The document discusses different types of investment that contribute to a country's capital stock and macroeconomic growth. It explains that there are three main types of investment: business fixed investment, inventory investment, and residential investment. Business fixed investment includes physical capital like buildings, plants, and machinery. Inventory investment includes raw materials and finished goods held by companies. Residential investment includes new housing construction. The document also discusses models for how companies determine their desired capital stock and reach that level over time through gradual investment, such as the flexible accelerator model of investment.
I apologize, upon reviewing the transcript I do not see any clear question being asked that I can directly answer. The discussion covered several concepts related to GDP, GNP, national income accounting and differences between various measures. Please feel free to ask a more specific question if you would like me to clarify or expand on any part of the discussion.
This document provides an overview of the Keynesian cross model. It begins by stating that the Keynesian model assumes there is unused capacity in the short run, rendering the supply curve horizontal. This makes the model demand-determined, unlike classical models where supply determined output. The model considers only the goods market, ignoring money and labor markets. It presents the goods market equilibrium condition as Y=C+I, where Y is output, C is consumption, and I is investment. It then makes two assumptions: 1) Investment I is autonomous (does not depend on other variables) and 2) Consumption C follows a linear function C=C0 + cY, where C0 is autonomous consumption and c is the marginal
This document provides teaching notes for a chapter on the costs of production. It discusses key topics like accounting versus economic costs, definitions of total, average and marginal costs, and cost minimization. It emphasizes distinguishing accounting and economic costs, understanding cost curves, and how costs relate to profit maximization and the supply curve. It provides questions to review the chapter, including questions about opportunity costs, true/false statements about costs, implications of marginal costs, cost minimization, and properties of isocost lines.
This lecture discusses national income accounting methods for measuring macroeconomic activity. It introduces three key economic agents - households, firms, and the government - and how they interact in a circular flow. It also notes that the government, which provides public goods, was omitted from the previous discussion of the circular flow diagram.
The lecture then explains that there are three main approaches to national income accounting: the output method, income method, and expenditure method. The output method values the total output produced across all industries in a country. However, this poses challenges with double-counting intermediary goods that are used as inputs by other firms.
Finally, it distinguishes between GDP, which measures all output within a country's geographical boundaries
Can 6 words impact millions of people !Prashant Roy
The Supreme Court is considering a challenge to the Affordable Care Act that hinges on the interpretation of six words - "an exchange established by the states". If the plaintiffs' argument is accepted, insurance subsidies would only be available in states that set up their own exchanges, not those relying on the federal marketplace. This could cause 7.5 million people to lose subsidies, resulting in higher premiums and fewer people able to afford coverage. It would disrupt insurer business models and the larger marketplace ecosystem created to support ACA reforms. Millions of insured people could lose their healthcare based on the interpretation of these six words.
The professor discusses the multiplier effect under flexible and fixed exchange rate systems.
Under flexible exchange rates, when money supply increases, the interest rate falls, leading to capital outflows and depreciation of the exchange rate. This shifts the IS curve right and makes the BP curve flatter, reaching a new equilibrium with higher output.
Under fixed exchange rates, a government spending increase shifts the IS curve right. Interest rates rise to clear the money market, creating a balance of payments surplus. Higher reserves shift the LM curve right until a new equilibrium is reached with higher output.
When money supply increases under fixed rates, interest rates initially fall, causing capital outflows that shift the LM curve back. This res
This document provides an overview and summary of key concepts from a lecture on macroeconomic theory and stabilization policy based on the classical model.
The classical model assumes full employment in the long run. It models the economy as having three sectors: the goods market, money market, and labor market. The demand side consists of the goods and money markets, while the supply side is the labor market.
Key identities and equilibrium conditions in the classical model are discussed, including: savings equals investment (S=I), the money market equilibrium of MV=PY, and the labor demand function derived from profit maximization of F(N)=W/P. Changes in the wage rate or price level could cause firms to hire more
The document is a transcript of a lecture on macroeconomic theory and stabilization policy. It discusses three main topics:
1. The professor corrects a mistake from the previous class regarding the intercept of the savings function line. The correct intercept is minus C naught plus S*T f, not just minus C naught.
2. When government increases expenditure (dG) and finances it through increased taxes (dT) such that the budget surplus does not change, the multiplier effect on output (dY/dG) is equal to 1. This is known as the balanced budget multiplier.
3. The professor provides a diagrammatic explanation of how the budget surplus line would shift if government increases expenditure and taxes to keep the

This document discusses macroeconomic concepts and national income accounting methods. It contains lecture slides and explanations from a professor on topics such as:
- Macroeconomic problems like business cycles and inflation
- Cyclical and long-run macroeconomic models
- Stabilization policy, Okun's Law, and the relationship between unemployment and output
- Measurement of aggregate variables in national income accounting, including GDP, GNP, personal and disposable income
- Components included and excluded from these aggregate variables based on national income accounting conventions
The professor provides examples and clarifies questions from students on these macroeconomic topics and accounting approaches. Key areas discussed are the treatment of depreciation, taxes, transfers, and social insurance
This document provides an overview and summary of a lecture on macroeconomic theory and stabilization policy. It discusses the IS-LM model, which uses two equations to solve for two unknowns - national income (Y) and interest rate (r). It explains that the IS curve plots combinations of Y and r that satisfy goods market equilibrium in the Keynesian cross model. It then introduces the concept of the money market and how Keynes expanded the demand for money to include speculative demand, based on the interest rate, in addition to transaction demand based on national income. The lecture elaborates on conceptualizing the overall assets market in terms of demand and supply and focuses on elaborating the demand for money component, where Keynes' contribution lies
This document provides a summary of a lecture on macroeconomic theory and stabilization policy. The lecture discusses business cycles and how they relate to changes in actual output levels and rates of change. It notes that a recession can be defined as successive quarters of declining growth rates, even if output levels are not falling. The lecture then addresses the problem of "stagflation" seen in some economies in the 1970s-1980s - when growth rates were falling yet inflation was high. This contradicted traditional Keynesian models, suggesting supply-side factors were involved. The lecture analyzes demand-supply diagrams and how demand-side policies cannot effectively address stagflation if caused by supply shocks. It questions policies adopted in a recent
The document discusses the effectiveness of fiscal and monetary policies. It presents three cases where fiscal policy is most effective:
1) When the interest rate (Ir) is zero, the fiscal policy multiplier becomes 1/(1-c)(1-t), making fiscal policy more effective.
2) When the monetary policy keeps the interest rate fixed at zero, the model becomes recursive with the LM curve endogenously adjusting to maintain equilibrium.
3) When the LM curve is horizontal, representing a liquidity trap scenario where the interest rate is very low, the fiscal policy multiplier again equals 1/(1-c)(1-t), making it most effective.
The document also discusses that fiscal policy becomes less
This document provides an overview and summary of key concepts from a lecture on the Keynesian model that allows for variable prices. It begins by recapping the previous lecture where the Keynesian supply function was developed based on a production function with labor as the single input. It then derives the positive slope of the aggregate supply curve based on the production function and labor demand equations. This shows that unlike earlier Keynesian models which assumed a horizontal supply curve, this model allows for upward sloping supply that is determined by technology and responsiveness of output to changes in employment. The document concludes by outlining the four equations that define the complete Keynesian model with variable prices: the IS-LM equations, production function, and labor
This document provides a summary of a lecture on measuring real GDP and prices. The professor discusses how nominal GDP measured at current market prices can provide misleading information if prices change. To obtain a true measure of real output, it is necessary to use constant prices from a base year to calculate real GDP. The GDP deflator, which is nominal GDP divided by real GDP, provides a measure of overall price changes in the economy. The professor also discusses how consumer price index and wholesale price index are used to measure inflation in India.
- The document discusses introducing the government into the Keynesian cross model (case b).
- There are two main changes: 1) Government expenditure (G) is added to consumption (C) and investment (I) on the demand side. 2) Consumption is now a function of disposable income rather than total income, where disposable income equals total income minus taxes plus transfer payments.
- Taxes are modeled as either a lump sum tax (fixed amount) or a proportional tax (a percentage of income). The model uses a proportional tax.
This document discusses national income accounting methods and measuring GDP using the income approach. It explains that the income method, also called factor cost valuation, measures GDP by looking at the total income generated in an economy during a given time period. GDP at factor cost is the income counterpart of GDP at market prices. To calculate GDP at factor cost from GDP at market prices, you deduct indirect taxes and add any subsidies provided by the government. This gives the total income received by the factors of production, including labor, capital, land, and organizations.
This document discusses the Keynesian macroeconomic model. It begins by deriving the Keynesian demand function from the IS-LM model. The demand function shows that as prices fall, output will rise, with a negative slope. Parameter restrictions like the liquidity preference (LR) can impact the effectiveness of fiscal and monetary policy and even make the demand curve perfectly inelastic. The document then notes that the classical model can be obtained as a special case if these parameter restrictions are applied. It outlines the classical model of the goods and money markets. Finally, it states that the discussion will now turn to deriving the Keynesian supply side model.
Labeling the virus share malware dataset lessons learnedJohn Seymour
This document summarizes the process of labeling the VirusShare malware dataset for use in malware classification machine learning models. Key points include:
- The VirusShare dataset contains over 27 million malware samples that were labeled using the VirusTotal API by 30 people over 6 months to overcome rate limiting.
- An index was built using PySpark to list each malware label and the chunks it occurs in, to minimize download size and time for retrieving samples.
- Words of warning are provided about not using the labels to compare antivirus vendors and that ground truth may be noisy due to inconsistent antivirus labeling.
- Useful extensions discussed are adding timestamp data and implementing stemming to help address inconsistent labeling issues.
This document discusses fixed capital, which refers to long-term assets that businesses invest in but do not directly produce goods. Fixed capital includes property, plant, equipment, land, vehicles, and machinery. It helps businesses by facilitating production over long periods of time. Sources of fixed capital include owners' resources, term loans, issuing shares, retained earnings, and issuing debentures. Examples include buildings, machinery, vehicles, and equipment. Fixed capital is important because it provides necessary infrastructure for businesses to operate and produce goods.
The document discusses the importance of feasibility reports in technical communication and business situations. It provides reasons for why feasibility reports are important before starting new projects. The key points made are that feasibility reports assess the availability of required materials, compare total project costs to potential benefits, ensure compliance with local laws, determine if timelines can be met, and evaluate how customer requirements will be addressed. Conducting proper research and considering technology, economic, legal, operational, and scheduling feasibility are essential before designing an important feasibility study.
You can think of outsourcing everything, including yourself. How do you outsource yourself? You can become a vendor that provides services to your company on a contract basis instead of being an employee. That is extreme, but possible. The other extreme is where the company employs everyone and makes everything. Now, this is extreme and impossible. Can a company make its own photocopiers? And coffee maker? Remember the old make or buy economic question? Exciting micro-economic analysis exercise back then. Now it’s a really life question – in-house or outsource?
A feasibility report is important in technical communication as it allows companies to determine if a new project or product is viable before starting. A feasibility report should examine the technical, economic, legal, operational, and schedule feasibility of a project. It is necessary to conduct research on these various factors to understand what resources are needed and if the project can realistically be completed as planned.
The document discusses the importance of feasibility reports in technical communication and business situations. It provides examples of key points to consider in a feasibility report, including technology, economic, legal, operational, and schedule feasibility. It also explains that a feasibility report is necessary before starting a new business project to determine if the required materials, timeline, costs, legal issues, and other factors are feasible.

Part 1: Application Transformation Case Study Dives Down to Bottom Line with ...Dana Gardner
Transcript of the first in a series of sponsored BriefingsDirect podcasts -- "Application Transformation: Getting to the Bottom Line" -- on the rationale and strategies for application transformation.
- The document discusses the ISLMBP model under a flexible exchange rate system. It finds that there are three dependent variables - output (y), interest rate (r), and exchange rate (e).
- Under flexible exchange rates, the monetary policy multiplier becomes stronger while the fiscal policy multiplier becomes weaker compared to the ISLM model.
- An expansionary fiscal policy could depreciate the currency if the slope of the LM curve is less than the slope of the BP curve, meaning BP is steeper. This suggests capital movement sensitivity may be lower for India.
This document discusses national income accounting methods and measuring GDP using the income approach. It explains that the income method, also called factor cost valuation, measures the total income generated in an economy over a given time period by factoring in incomes to all factors of production, including labor, capital, land, and organization. GDP at factor cost is the income counterpart of GDP at market prices, and can be calculated by deducting indirect taxes from GDP and adding any subsidies provided by the government. The document provides examples to illustrate how subsidies and public sector surpluses are treated in national income accounting.
This document provides an overview of balance of payments accounts and open economic macroeconomics. It discusses that balance of payments is an accounting procedure that records surplus and deficit items related to a country's interactions with other countries. The main accounts included in balance of payments are the current account and capital account. The current account has three sub-accounts: the trade account, services account, and transfer payments account. The trade account records exports and imports of goods, while the services account records exports and imports of services such as shipping, professional services, and dividend/interest payments.
- The document discusses macroeconomic stability and equilibrium using the IS-LM model.
- It explains that with one variable (output/Y), stability is achieved if the change in output (dy/dt) becomes smaller over time as equilibrium is approached.
- With two dynamic variables (output/Y and interest rate/r) in the IS-LM model, stability conditions can be analyzed using a 2x2 matrix where the determinant is positive and trace is negative. This ensures the system converges to equilibrium after a shock.
This document provides a summary of a lecture on the classical macroeconomic model. It begins by explaining the key components of macroeconomic models - the goods market, money market, and labor market. It then discusses the assumptions of the classical model, which describes the long-run economy with full employment. Specifically, it assumes no government, a closed economy with no trade, and that the private economy consists of consumption and investment. The lecture then sets up an equilibrium condition for the goods market using two identities: the output identity equating total output to consumer and investment goods output, and the income identity equating income to consumption and savings. It shows that equilibrium in the goods market occurs when savings equals investment.
This document provides a summary of a lecture on macroeconomic theory and stabilization policy. The lecture begins by distinguishing between microeconomics, which deals with individual economic problems, and macroeconomics, which must aggregate individuals and consider more complex problems facing entire economies, such as inflation and unemployment.
The lecture then discusses different economic systems, including socialist systems where the government controls production and allocation of resources, capitalist systems where capital is privately owned, and mixed economies. Examples of different countries representing these systems are provided. The lecture focuses on macroeconomic models that examine the very long-run, long-run, and short-run/medium-run behavior of economies. It explains the assumptions and analytical frameworks used in these different time horiz
This document provides an overview of geotechnical engineering and soils. It discusses the origin of soils through weathering of rocks, including physical and chemical weathering processes. It describes different types of soils based on their mode of deposition, such as alluvial, lacustrine, marine, aeolian, and colluvial soils. It also discusses major soil types found in India like black cotton soils, marine soils, and desert soils; and their key engineering properties. The document provides useful background information on soil formation and classification for geotechnical engineering applications.
This document does not contain any meaningful information to summarize in 3 sentences or less. It consists of repeated symbols and characters without any context.
The document provides equations to determine the elastic curve of beams under different loading and boundary conditions. It gives the equations of the elastic curve in terms of the slope and deflection at points along the beam. The maximum deflection is calculated to be wL4/1823EI between supports A and B for a beam with a constant distributed load w and of length L with both ends fixed.
The Rise and Fall of Ponzi Schemes in America.pptxDiana Rose
Ponzi schemes, a notorious form of financial fraud, have plagued America’s investment landscape for decades. Named after Charles Ponzi, who orchestrated one of the most infamous schemes in the early 20th century, these fraudulent operations promise high returns with little or no risk, only to collapse and leave investors with significant losses. This article explores the nature of Ponzi schemes, notable cases in American history, their impact on victims, and measures to prevent falling prey to such scams.
Understanding Ponzi Schemes
A Ponzi scheme is an investment scam where returns are paid to earlier investors using the capital from newer investors, rather than from legitimate profit earned. The scheme relies on a constant influx of new investments to continue paying the promised returns. Eventually, when the flow of new money slows down or stops, the scheme collapses, leaving the majority of investors with substantial financial losses.
Historical Context: Charles Ponzi and His Legacy
Charles Ponzi is the namesake of this deceptive practice. In the 1920s, Ponzi promised investors in Boston a 50% return within 45 days or 100% return in 90 days through arbitrage of international reply coupons. Initially, he paid returns as promised, not from profits, but from the investments of new participants. When his scheme unraveled, it resulted in losses exceeding $20 million (equivalent to about $270 million today).
Notable American Ponzi Schemes
1. Bernie Madoff: Perhaps the most notorious Ponzi scheme in recent history, Bernie Madoff’s fraud involved $65 billion. Madoff, a well-respected figure in the financial industry, promised steady, high returns through a secretive investment strategy. His scheme lasted for decades before collapsing in 2008, devastating thousands of investors, including individuals, charities, and institutional clients.
2. Allen Stanford: Through his company, Stanford Financial Group, Allen Stanford orchestrated a $7 billion Ponzi scheme, luring investors with fraudulent certificates of deposit issued by his offshore bank. Stanford promised high returns and lavish lifestyle benefits to his investors, which ultimately led to a 110-year prison sentence for the financier in 2012.
3. Tom Petters: In a scheme that lasted more than a decade, Tom Petters ran a $3.65 billion Ponzi scheme, using his company, Petters Group Worldwide. He claimed to buy and sell consumer electronics, but in reality, he used new investments to pay off old debts and fund his extravagant lifestyle. Petters was convicted in 2009 and sentenced to 50 years in prison.
4. Eric Dalius and Saivian: Eric Dalius, a prominent figure behind Saivian, a cashback program promising high returns, is under scrutiny for allegedly orchestrating a Ponzi scheme. Saivian enticed investors with promises of up to 20% cash back on everyday purchases. However, investigations suggest that the returns were paid using new investments rather than legitimate profits. The collapse of Saivian l

"Does Foreign Direct Investment Negatively Affect Preservation of Culture in the Global South? Case Studies in Thailand and Cambodia."
Do elements of globalization, such as Foreign Direct Investment (FDI), negatively affect the ability of countries in the Global South to preserve their culture? This research aims to answer this question by employing a cross-sectional comparative case study analysis utilizing methods of difference. Thailand and Cambodia are compared as they are in the same region and have a similar culture. The metric of difference between Thailand and Cambodia is their ability to preserve their culture. This ability is operationalized by their respective attitudes towards FDI; Thailand imposes stringent regulations and limitations on FDI while Cambodia does not hesitate to accept most FDI and imposes fewer limitations. The evidence from this study suggests that FDI from globally influential countries with high gross domestic products (GDPs) (e.g. China, U.S.) challenges the ability of countries with lower GDPs (e.g. Cambodia) to protect their culture. Furthermore, the ability, or lack thereof, of the receiving countries to protect their culture is amplified by the existence and implementation of restrictive FDI policies imposed by their governments.
My study abroad in Bali, Indonesia, inspired this research topic as I noticed how globalization is changing the culture of its people. I learned their language and way of life which helped me understand the beauty and importance of cultural preservation. I believe we could all benefit from learning new perspectives as they could help us ideate solutions to contemporary issues and empathize with others.

In a tight labour market, job-seekers gain bargaining power and leverage it into greater job quality—at least, that’s the conventional wisdom.
Michael, LMIC Economist, presented findings that reveal a weakened relationship between labour market tightness and job quality indicators following the pandemic. Labour market tightness coincided with growth in real wages for only a portion of workers: those in low-wage jobs requiring little education. Several factors—including labour market composition, worker and employer behaviour, and labour market practices—have contributed to the absence of worker benefits. These will be investigated further in future work.

1. Macroeconomic Theory and Stabilization Policy
Prof. Dr. Surajit Sinha
Department of Humanities and Social Sciences
Indian Institute of Technology, Kanpur
Lecture - 12
Now, I have a few things to talk about investment which is started in the last class. Then
I would conclude investment and go onto the second half of the course, which is much
more useful as a as a tool of economic analysis or as a economic theory which can be
used to understand things. So, the second half I will begin, let me complete investment
part, investment is an additional thing I am doing in this course because many people do
not understand what it means by investment. So, briefly what I said in the previous class
is that investment can be of two types, net investment and replacement investment.
Together they are called gross investment or investment. So, investment expenditures in
a country need not be a new machine created, it may be old machine replaced and still
part of investment, but that is replacement investment.
The example I was trying to give you suppose this chair breaks down and we get a
replacement, that is not new investment, chair was there, but I get a replacement which is
a new thing produced by some company, but it is not part of macroeconomic net
investment or new investment. Typically, in a country more than 80 percent of the
investment in a year is replacement investment, which is sometimes called a precession
investment or depreciation of capital lead to depreciation of capital creates.
This requirement of replacement investment, we call it sometimes maintenance cost,
service cost all sorts of names we have now. So, if that is true than in macro economics
sense what kinds of investment do take place in a country in a year, well if you look
around you find that there are three kinds of investment activities going on all the time,
one which is famous investment. We all know that called business fix fixed investment,
business fixed investment is the investment that many people think, even lots the people
say. If you ask a businessman he would talk about money he put in.
So, it is business activities that connects investment usual in peoples mind and business
fixed investment is just not how much money you put in, but how much of physical
capital stock the company has acquired. Physical capital stock of a company consists of
office spaces, buildings plants, factories whatever machines tools they are part of
2. business fixed investment. Except for say the other cost that a company has say raw
material, costs, labor costs, they are not a rent.
They are not part of investment expenditures or not part of capital stock. Capital stocks
consist of if IIT Kanpur put this building it is part of the capital stock of IIT Kanpur.
When you are the fixture inside our part of the capital stock of the of IIT Kanpur and I
was telling you that in a war, the worst thing that can happen to a country is this
historical accumulation of capital stock, historical means what time. You cannot build
the building one night, over time in a month, in a year and a Kanpur city cannot be
created in one month, but you can destroy Kanpur city in one month in a war.
So, the huge loss that can happen to a country is loss of capital stock. So, these are part
of investment activities, part of there a portion is replacement investment and a portion
will be new investment like new building. At IIT recently we had new capital stock
acquired at IIT Kanpur, we have seen that towards in the city many office, buildings,
labs, etcetera have come off new cold lab building, etcetera, etcetera, alright?
So, business fixed investment is something that usually connects people, connect when
they talk about investment, but there are other kinds of investments. The one I talked
about in the previous class is the inventory investment and the inventory investments are
unfortunately both, just not finished goods. It can also be goods, it can be raw materials,
everything part of inventory investment.
So, here the word capital stock becomes very thin are raw materials essentially part of
capital stock, no finished goods of a company jam, jelly, butter, part of capital stock of a
of a company. No, but in a macro sense inventories are part of the investment activities
of a country. So, if a company is putting in more into inventory either purchasing raw
materials or producing finished goods, keeping them there incase future there is more
demand. They can bring it out, they all come under investment activities in macro sense,
not in the strict micro sense, but in a macro sense. They are part of investment activities
and I told you about inventories there some cost, you put in money, you create a go
down, you construct a storage, cold storage depending upon the products you have.
So, you borrow money from the bank, there will be an interest cost, than you have the
running cost, the refrigeration cost, the labor cost involve with it. So, inventory
investments are associated with their number of other cost associated with inventory
3. investments, alright? The final investment that I need to talk today, but before that I need
to talk about rather things, is it the residential buildings are also not company buildings,
not plants factories residential buildings are part of the capital stock of a country.
So, any new building coming up means adding a capital stock. So, it is essential
investment activity, someday sent a mail to me before exam is it part of GDP, essential is
it part of GDP infrastructure expenditures. Then the services you get from that building
year after year after year are also put in part of the GDP of the any future year services. It
may be your own house, it may be your rented flat it does not matter. So, residential
buildings are also part of investment activities constructive buildings, you see apartment
buildings coming up multi storied buildings. You go to any city today you will see that
that is essentially creating capital stock of India called residential investment, alright?
Now, before I talk about residential investment I just wanted to make one or two quick
points. That which you know in case of inventory investment, costs of various types I
told you in case of business investment. There are very specific models and often these
models are micro economic models and one of the micro economics exercises I did I
said. Let us assume a company minimizes cost and objective function is to minimize cost
subject to an output it wants to produce. Now, as soon as it wants to produce an output it
has planned that output. Now, the question is how to organize its production process to
produce it.
So, it has to select the raw materials and the other inputs labor etcetera and machine. So,
it has to also select a technology that it will use to produce it and you can set up a micro
economic problem, which is called constraint cost minimization problem where you
minimize cost total cost subject to an output. It wishes to produce and through that
exercise I told you that you can get a capital demand function and labor demand
function, any input you may have you can get a fact demand function. The demand
function is essentially what are algebraic equation I wrote where on the left hand side
you have k and on the right hand side you have bunch of parameters and variables of the
module. In the previous class I did that is the capital demand function.
So, the best way to conceptualize to see the capital demand function is to put k is the
function of the cost of capital R. I put rental cost of capital and put all other variables
under one club, one gross variables say Z know, you can see K and R are inversely
4. related. If you look at that algebraic equation you will see K and R are inversely related,
meaning it is telling you there is inverse relationship which we called demand function.
Demand function are inverse relationship between price and the item concerned.
So, more capital would be demanded if rate of interest falls than I told you the idea
behind that is there is something called diminishing marginal pro activity of capital. If
you hire machine in this room, after a point machine will give you, giving a increasing
output, after that it will give an extra output, but a smaller amount. Next time you have
other machine it will give an extra output, it contributes to total output and there is a
extra that you get from hiring that machine. Combining it, but that extra is becoming
smaller which is called diminishing marginal pro activity of capital.
So, capital becomes less and less pro active as you hire them, reason is capital you are
hiring keeping all other factors of production constant. So, there is an optimum that you
can have number of chairs, see in this room an optimum numbers of student you can
teach in this room. You go beyond that the pro activity of the education that you have
imparting on students would go down, some would not see my face, some would be if
too many people are there, some would be standing in front of somebody because there
is not a chair there, alright?
So, all these pro activity business is also in relation to other factors you know. If you
increase the class size I have a better amplifying system or whatever microphones,
etcetera lights class to increases. Yes, I can accommodate 200 students here. I teach
efficiently, but given the size given other factors like the size of the room and other
features that you have. It is not possible to increase pro activity by just employing more
and more amount of some other factor. This is diminishing marginal pro activity.
So, if R is the cost of capital and diminishing marginal, pro activity is downward sloping
line. It will be a obtain when R is called to diminishing marginal pro activity because
beyond that what you are saying the pro activity is less than the cost of buying a machine
or renting a machine. So, the return is less than the cost, alright? Pre prior to that the
return is greater than the cost prior unit of extra machine. So, you keep on employing
machine. So, you get an equilibrium condition there, R is called to marginal pro activity
of capital of labor, what I am saying is if you are not following me.
5. (Refer Slide Time: 12:16)
If you have diminishing marginal pro activity of capital, essentially what you are saying
is that suppose, I have capital here. I have marginal pro activity of capital here and it is a
downward sloping line, marginal pro activity of capital which is diminishing marginal
pro activity of capital as you have more capital.
If the rental cost of capital is given said the rental cost of capital is somewhere here or
not. Then clearly you would hire only up to that point where it marginal pro activity is
called to rental cost of capital. Because the rental cost of capital is saying that this is the
cost you pay to hire an extra machine or per unit cost when you purchase a machine,
alright? Per unit cost can be calculated like if a machine has a life of ten years, total
amount say 1 lakh rupees you pay. Then per year it is 10000 rupees plus some servicing
cost, it can be rental cost of capital, alright?
So, is this rental cost of capital marginal is diminishing. Of course, you would not go
beyond that point to hand more. Let us say this is some K naught, you would not go
beyond K naught because the marginal product which is the return to the company from
extra unit of capital. That you employ of rent is less than the cost which is here. So, it
gives you an equilibrium condition.
So, what do you essentially have is therefore given the parameters of the model, in that
micro model if you know the rental cost of capital, alright? A company can decide what
would be the desired amount of capital wish to have to produce 5000 units of an output
6. per year. This is the amount of capitalize required, it can be worked out like an
arithmetic problem from that capital demand function that I showed you once. You have
that once, you have that desired capital. Then the question is how long the company will
take to obtain that amount of capital, because capital is an expensive item. It may not
have all the money initially to buy it.
So, it may gradually purchase capital stock and reach that optimum level. So, the micro
economic theory with this diminishing marginal pro activity of capital and rental cost of
capital and other parameters like the labor cost, etcetera. What you essentially obtain is if
a company wants to produce this amount of output, than the company can also find out
what is the amount of capital I required. Now, the question is how I reach that capital
stock that is called the desired capital stock.
So, essentially if from the capital demand function, you have the desired capital stock.
The question is now how will it take to reach that desired capital stock and you have how
much investment activities that you will take place in very cruel terms. If number of
machine today is 5, I desired 10 machines. My physical investment is roughly equal to 5
machines in real terms in money terms. You can multiply that with price desired, capital
stock is 10 machines, the investment that I would undertake is equal to 5 machines, very
simple. In physical terms, in money terms you multiply that with price, job done.
If you rent that you multiply that with the rental cost per unit of time. One year rental
cost you can get a cost total investment activities, you can say in some sense that well in
some sense, yes, alright? Now, as soon as I raised this issue that there is a desired capital
stock and the company will now have to reach the desired capital stock, because it
wishes to also produce desired level of output which is a target output. Then there are
also many models I tell you investment literature is just full of models. Lots of models
are there, I need not talk about that, I am just giving you the broad concepts.
There is the one that I have found out in your textbook mentioned is called the flexible
accelerator model of investment flexible. Accelerator model of investment, what it is
very interesting thing, this is the conceptualization as to how a company reaches a
desired capital stock. The flexible accelerator model of investment essentially says.
7. (Refer Slide Time: 17:09)
Flexible accelerator model of investment, what it says a company adjust towards the
desired capital stock, only gradually, slowly it does not acquire the capital stock
overnight. So, it basically sets of a model which is in this kind of a time frame. There is a
time say 1 period, 2 period, 3 period, 4 period, 5 period, 6, 7, 8, 9, 10. Suppose, the
capital stock right now is somewhere at the 0 period is somewhere here. This is the K lag
one period, the capital I have from the last period, alright? Suppose, the desired capital
stock k start is suppose here. Now, you can draw a line here saying said this is the height
I want to reach and I am at a height here, alright?
So, what path should I take? Many people suggests various things, one can say that at the
end of the tenth period I will reach this point. So, one can conceptualize a path like this, a
linear path, every period I undertake and in a honor at on the linear line some amount of
investment that one can think about a path like this. It increases initially very much and
gradually tapers off. One can have a very slow beginning and then rapidly concludes
investment, who knows it is the company’s decision.
It depends upon a number of issues, how much money it has, how much it can get, what
is the availability of machines, alright? In the first period it may not acquire any
machine, in the second period it acquires, it starts working with old machine, only
second period acquires one unit. In the third period it may not have enough money, again
8. in the fourth period it acquires the second unit. So, it can be a very much step function, it
can very much be a step function.
(Refer Slide Time: 19:55)
Now, the flexible accelerator model essentially saying that the capital stock or what you
call that the net investment, I think yeah essentially the capital stock today will be what I
had yesterday plus only a lambda fraction of K star minus K lag, one period will be
undertaken, well lambda lies between 0 and 1. Therefore, I can rewrite this as K, K
minus 1 is equal to lambda k star minus k lag. One period this is net investment, this K
minus, K minus 1 is net investment. Essentially, this is Net I is equal to lambda K star
minus K lag 1 period. This is Net I actual capital stock that I have today, minus the
capital stock I had yesterday is my net investment today.
Now, that today and yesterday and tomorrow can be any time period on 11th of July. I
can calculate that again on 11th of August. I can go and calculate that number, than 11th
of July number will be yesterday, it can be anything, alright? So, do you saying there is a
gap between desired capital stock, 10 machines and current capital stocks said. Today 5
machines, how much investment do I undertake in any period? I only add fraction
lambda of the gap, that fraction can be anything, 10 percent, 5 percent, some machines
takes time bring parts and bolted down. It requires a whole lot of cost and then it is ready
to be used, alright?
9. It comes in parts and therefore, you can in fractions of investment undertaken. Therefore,
what I am saying is that any amount that the gap you bridge, you what used you feel can
be only a fraction in any one period and therefore, suppose you take lambda to be half.
(Refer Slide Time: 22:20)
Suppose, take an example lambda is equal to half, 0.5. Now, what will happen to this
line? This is K lag one period, this is K star. So, in the very first period by the end of the
first period, period one half of that is met. You are already here half of the gap in the
second period, whatever remains between these two you can, you can meet half of that.
So, essentially what is happening is you go here from here, from here you go here, then
here, here. In this way step function can be emerged which is a little bit more and then in
a continuous time period it will become smaller and smaller, but it may require say four
periods to conclude it. Last one is you ignore lambda is equal to half, you just jump to
the end.
So, lambda value can change, so the a step function path, a step function like path the
company can follow to reach the desired level. So, this is actually what happens in real
life company decide how much to produce in the coming 5 years, 4 years, 2 years. Than
it decides how to organize that production and therefore, what other things required.
Then it gets a desired capital stock and then the question is how it gets the desired capital
stock realized? Actually it is there in the company in the plant on the short flow, it
10. cannot have various approach. So, this is one thing which is you may find in your
textbooks to talk about this desired capital stock, etcetera, business, alright? Okay?
Having said that what I would do, I need not going to there are so many issues related to
investment and that is the big issue in a country. Now, they are also talking about how to
pick up investment because Indian GDP growth industrial output growth is falling
negative quarter. After quarter GDP growth rate is falling somebody is predicting, it will
be only 5 plus percentage point. So, these are the basic issues one gets into. So, I need
not get into many more issues, if anybody has interest can pursue that. There is enormous
amount of literature on investment, what I need to tell you now is a little bit about
residential investment, alright?
Now, residential investment as you know can be broadly of two types, owner’s house
only. The one you see abroad for instance if you watch a Hollywood film, a lane and
than one side there is one storied houses. On both sides each of the house is owned by a
person, owner’s house like IIT Kanpur type, four houses single storied buildings or you
can have essential complex and apartment complex, where in one building many people
can live.
So, there can be various types of residential buildings, there all together called the
housing industry all called housing industry in any country, alright? Now, at any point of
time when you look at the residential buildings or house is this part cleared, the flexible
accelerator model what they say this kind of conceptualization is there. So, the
residential investment essentially talks about houses.
11. (Refer Slide Time: 26:35)
So, at any point of time there is a stock of houses, there is a stock of houses that exist in a
country, where you can go and live. You can ask somebody to live, you can rent it out,
you your self can rent it, purchase it, whatever a stock of houses are there, this is called
the short run. The short run supply of houses, this is the short run supply of houses at any
point of time.
So, essentially what you have at any point of time if this is housing market and suppose
this is price of housing. You have a supply of houses which is essentially the short run
supply of houses which is very inelastic, perfectly fixed, very inelastic. It would not
change because why because houses take time to construct. At any point of time the
number of flats you can have in a city and houses, own your own houses will be fixed
and but there can be lot under construction.
But I am not taking the data on under construction, I am only talking of complete houses
where I can go and live if I want, if I have the money, alright? That stock of house is
essentially a very inelastic line is called in economics and inelastic line is perfectly
inelastic, vertical line inelastic means if price is change supply does not change at all,
complete inelastic insensitive. You can say a human being is insensitive, you scold him
he does not respond, you give him punishment he does not respond, anything happen he
does not respond. Like in inelastic line is perfectly insensitive to price changes, but there
12. is a demand curve for houses which can be a normal demand curve which can be a
downward sloping line, alright?
So, depends upon how much demand you have for residences in a city, say Kanpur city
in the year 2012. Number of houses that is available you can get a market price of houses
which can be thought about, if it is owner house than entire price, it is an apartment
entire price. If it a rented flat what is the rent per period, say per annum or something,
alright?
Now, so the price of house P H can be interoperated various ways, it was vary from type
of houses, you have it is the owner house is the price. You pay is the flat, the price
apartment cost 12 lakhs, 20 lakhs, 30 lakhs, 40 lakhs, whatever. Depends upon the area
and if it is a rented flat, what is the rent per month which multiply by 12 will give you
the rent per annum. Now, at a point of time I want to tell something, the supply and the
demand for houses are also influenced by particular demand for houses, are often
influenced by a number of other factors. There are number of other factors which
influenced the demand for houses, not so much supply, supply does, but I will talk about
that.
There are other factors that influenced just not the price, just not the price there are other
factors which influenced the demand influence, the demand for houses. Of course,
demand is a function of price, if the price is low, more demand for houses would be
there. There price is less demand for houses would be there, but there are other factors.
So, matter can anybody tell me what are the other factors which can also matter, when it
comes to a demand for houses in a society, in a country as a matter in a macro economics
sense houses are part of something.
We call property sometimes, it is essential I do not have a house up to live, but it is still
also part of your wealth because normally what happens buying a house, buying a flat or
an apartment requires a lot of money. The money magnitude and in the current scenario
where property price is going up every day is also considered to be part of your wealth,
an individual side I live there, but also it a part of my wealth tomorrow if necessary.
Hopefully, nothing will happen if any on forcing thing happens I can sell of this property
at a reasonable price, have the cash go and live in a smaller flat rented flat somewhere by
sell it off and get the money.
13. So, it is like wealth like gold, like jewelry, like share certificates, houses also have a
dimension which is it is part of wealth. Now, here comes the complication if it is part of
wealth than if an individual, when its basic needs are met he has more money. There can
be a question in his mind whether to put the extra in another property or whether to put
the money in a fixed deposited account in a bank, buy share certificates bonds of
governments or what jewelry gold. There are alternative forms of wealth in which an
individual can put money in put his savings. What I am trying to say is after point, this
property is also a necessary thing for my existence, because I have to have a place to live
place to stay, but after a point when more money is there more saving is there with me.
I can think about a business, than alternative forms of property come in to the picture,
should I go for a property. Two things will matter there, what is the current price at
which I would buy it and what are my expectations about future property prices, because
now I am businessman, I have my essentials. This is extra I am doing for further gain.
So, if future prices are very prospective in this city, see in Delhi, Noida, Bombay,
Calcutta, Madras, Bangalore, etcetera. Oh I should buy a property, it becomes an
investment activity a different kind of investment, a personal investment activity where I
put money in like in the share market, I make money out of it, alright? Now, you see this
is a problem there are other factors which are coming into the picture which can
influence the demand for houses or property. Now, I do not called it houses, maybe I call
it property, it can be land also which can come into property, but here let us concentrate
on residential houses. Many people buy flats and rent them out, you know is called sub
renting like you people when you go to a city.
Suppose, I buy tomorrow I become rich one day which would never happen, IIT Kanpur,
but suppose I become rich, I can dream about it, I go and buy a couple of flats in
Bangalore. I know IIT Kanpur students go there and students know me, I know the
students. I said you do not worry, you pay me a rent we will have a contractual
agreement for 4 years, 2 years whatever and this flat in a good location in Bangalore and
I make money on that. I invest that is my investment, I am not living there IIT Kanpur
has provided me a house, I live here.
So, it is not essential, but that is a form of kind of personal investment activity and
therefore in order to do that what I would count. What is important in economics is that
14. whenever I do check a choice, there are alternatives that are important to be taken into
consideration. If the returned from the share market, if the return from the bank if the
returned from the bonds, if the returned from the gold, if the returned from the something
else an alternative form of wealth is comparable to a returned to a property. And I find
the returned form of property like a house if I owned is higher, I would choose that is
like maximizing profit in economics. What we called we maximize profit at a personal
level, we can say maximizing returned, alright?
So, the housing market is now getting quite complicated, it is not just to live there, it also
to make money and if my demand for houses go up what will happen? If the demand
curve shifts in the short run suddenly demand depends upon a very slow variable like
people. Suddenly there is a migration where I have seen that happening in Calcutta,
suddenly there is influx of Bihari people. In 1971 with the Bangladesh war, you would
not believe me how many people cross the border into Calcutta and West Bengal, you
were not born there, but I have seen that myself.
The demand in the short run also is a very fluid variable I tell you, it can be suppose the
metro just opened. It was getting under construction, but this year the metro open
immediately property prices demand for housing will change, which direction it will
change I cannot predict, but immediately very short run phenomenon or short run
situations variables starts effecting property prices. I tell you influx of people, I told you
my goodness Calcutta housing rents starts going up. Therefore, alternatives forms of
wealth, what kind of return they have matter, what happens in the property market or
residential housing market also, alright?
So, I am inter changing using property market and residential housing remember, but
property is much more than that people can buy land and call it property also. Property is
just not housing property, can be other things to just a plot of land can also be part of
that, I hope you are enjoying it a little bit too and following it. This is how it gets
complicated, social science there are too many variables that starts coming not like
physical science. You know the number of variables and then you play with it and find
out experiment social science. Suddenly other variable you never thought of variable.
Now, it has become important world recession property price, but India’s globalize and
world recession has becoming important. Now, I have fund now how to model it what
15. kind of relationship which can have, you think about it test them. Social science is very
very open, in some sense you cannot close it and say I have done enough, tomorrow
something crops up, alright? Therefore, the various kinds of and then in the western
world you have mortgage, etcetera. The interest cost are very important, western world
do you know what happens which is becoming popular in India?
You do not buy property from your savings, you start earning, get married. I have seen
young couples, my classmates who did not go for PhD got married and the first they did
was they just started earning, may be husband and wife both are earning. They bought a
house, how did you manage? I cannot imagine in India, my father never had house.
So, I cannot imagine either. So, I said how did you manage [FL] under mortgage [FL],
not in Hindi. They did not tell me, but this is all under mortgage. Mortgage means what
[FL] you go to the bank, mortgage your house, you take a loan against that house. It
house becomes yours except conditional, you have to pay the interest cost, the mortgage
cost. Once the interest cost and the loan has been repaid, the house become fully your
house, you owned it. Until you do that it is under the mortgage scheme of the bank, the
financial institution.
So, bank can confiscate that. That is it, yeah and how what guarantee do you have that
you would repay the loan? It is thousands of dollars you talking about. Oh my goodness
and those days I was very naïve, whenever they used to talk about dollar I think my
goodness convert that into Indian rupee, which you never do. You live in a country
which has dollar. Why would you convert that Indian rupee unless you are in India and I
am see my goodness, that amount of money and then I was very naïve. I would say that
amount loan you have taken from the bank, they saying yeah we do that all the time and
you have every guarantee to repay. Usually we do, but then the country is get into
recession. They do not repay, house get mortgaged, banks confiscate that, but economy
is very down there. Then what will the bank do? Sell the house to whom, which is
happening in the western world.
So, banks are in trouble, they give it out these loans credit, that is the system functions
the economy is floating on credit, which means what future promises payments. If it does
not go through fine you kick out that person [FL], whatever they can sell, resell, rather
they sell sold off. Suppose, they went, but what will the bank do in the economy,
16. recession, bank cannot just sell it off to anybody. There is no buyer, but banks money are
all tired up. This is precisely what has happened in the western world. The credit system
has put them into trouble which is part of their culture in India.
We did not have a credit system, I remember whoever my friends and friends families
parents, whenever earlier I am talking about what a flat, what a house, bank never came
into the picture is there savings when they retired. The provident fund income, the
personal savings saved in banks, they used to bought a flat, but now it is changing.
Now, it is changing, a lot of bank loans are involved, we are become westerner. Now, be
careful it looks very nice if the economy is doing well, if you have a job, but if you lose
your job [FL], but so it becomes part of the cultural thing in a country. How you know
what kind of food, when you get a what kind of clothes you wear, how you talk to
people, how you treat your relatives and friends. What you do if you have to purchase,
do you go to the bank and take the loan all the time? Or use your savings in a poor
country like India? Certain habits are very good, it is not a credit base system.
If you have money in your bank than you buy, if you cannot afford it, you do not have
money, you do not buy it, but aboard is not like that. The western world is very much
credit system, credit based, you take a loan every time and bank is always willing to give
you loan. My goodness and if the loan is not repaid, this what has happened, Europe,
North America, this is precisely what has happened, the financial nothing more than that
and some cheating going on.
Now, what has happened I tell you, suppose in Noida suddenly there is an influx
highway constructed, [FL] metro, [FL] property pirates are shooting off, everybody
wants to buy a property. There is no problem to travel from Noida to Connaught place
and work because the metro is there and highway, new highways is there.
17. (Refer Slide Time: 44:29)
The demand for houses will shoot up. What was happen to the price of in the housing
market, in the short run is not flexible, will shoot up [FL]. This will give rise, the short
run to one very interesting thing. The long run supply of houses in a particular area in a
particular economy depends upon the short prices. If the short run prices are good from
the point of view of the builder, more builders will be encouraged to construct houses.
So, in the long run what you have the supply of houses, which is the flow of supply
called the long run.
(Refer Slide Time: 45:16)
18. The flow supply of house is influenced by the short run price and short run demand and
supply, essentially that is short run demand and supply and in the long run what you have
the flow, supply of houses will be an upward, sloping line is a long run supply. That is
the short run supply and there is a long run supply that will be upward sloping as prices
increase in the short run. In the long run builders, more builders will come and produce
more, but it will take time. That long run quite a bit of long run, for an apartment
building I think about 2 years it takes, if not more to completed these days. So, the long
run sometimes the calendar time period can be quite long, but do you understand what I
am saying, the short run tells the builders how much return is there.
So, they go into a long run how much more they would supply. So, the long supply is
more elastic, if the price is high they will supply more, if the return is low in a place, the
place is dying, industries are dying, people are moving out, the supply would shrink, no
more supply. So, there is a flow of supply in the long run and a very stock supply in the
short run. Stock means stock of cash, pocket, I can count taking all the people, how
much cash I have, that does not mean that is the cash. You can only have this number of
people if you go to bank. If you give us time, we can have a flow supply of cash which
can be much more, but the stock supply I want to take.
So, everybody takes out the cash they have in their pocket, somebody have 5 rupees,
somebody has 100 rupees, somebody has 50 rupees, somebody has none and I can
calculate the stock of supply, because I have to do something with the stock today, right?
Now, slow flow might determine the kind of target oriented. It can be how much cash we
need and give us time ourselves to reach the target. So, in the short run therefore, when
there is influx of people, what happens in a place like Bangalore? Do you think the
market price is the price that the renters pay? Just one question before I go for a break, is
the market price the only price that the renters pay?
The tenants pay, there is one more price which is not shown there, which they pay is the
under the table payment, 2 months, 6 months, advance rent, no receipt is required in
India, it is very general practice. In foreign country it is never a practice and this practice
is primarily because of shortage of houses, shortage of housing.
So, that demand pressure is so much that the owner of the house makes an extra profit
which is not shown in the diagram, which is more than the market price. Market price is
19. something they pay every month, may be additional thing called [FL] in Bengali and
Hindi and other languages, which they make under the table payment for which no
receipt is given. It precisely depends upon the demand supply relationship in the short
run. In the long run it may ease [FL] may go down. If more houses coming to the picture,
because the return is high market is a very funny situation, market is so high price today,
but high may attract more producer tomorrow.
The price high price may become a low price tomorrow, but always in relation to how
much demand you have. If the demand is multiply more than the houses at any given
time frame, given time period than God help you. The prices would never come down,
prices would keep on rising if the demand increases more than supply, clear? So, this is
roughly the investment story I wanted to tell you.
So, next thing what I do is I will gradually get into more algebraic model and more
interesting models, in fact the most famous topic. Now, I will get into topic number 6,
the IS LM model, this IS LM model is originally due to a famous paper written by a
noble orate in economics and since then it has been there, important part of macro
economics theory. The IS LM model I will begin today, topic 6 and I will continue with
this few days.
(Refer Slide Time: 50:55)
IS LM model. Now, you have seen in the Keynesian cross model, the first Keynesian
model that the money market was ignored. We had a very simple supply relationship
20. with the aggregate supply was horizontal and the demand curve. Determine the output
level in the economy and the demand was also very simple, there was no investment
function.
Investment was autonomous then there were other autonomous components, government
expenditure, consumption, transfer, payments, they were all autonomous. So, that a
naught terms was trying to proxy for that represent that and the important role that was
played was that role of the consumption function, because consumption was a function
of income. So, any income produce in economy would be affected by consumption and
consumption affected by income, because consumption is function of income.
So, that was the key factor there in the Keynesian cross model. The consumption
function the in the IS LM model, essentially I extend that short run frame work to
include two things, one investment will love be a function of something and I will bring
in money market. Otherwise, it is just like the Keynesian cross model. So, two changes
there are coming. So, in topic 6, I will still assume a short run model where the supply
side will be glued, prices are constant, but I will make two changes to the existing
Keynesian cross model, one I will think about an investment function. Now, two I will
consider money market.
So, money market will play a role now. So, after that what do you think will happen to
complete the modeling macro modeling? I need to bring in only labor market at some
stage, than the Keynesian model is complete like the classical model. If you open your
note will you see there is a goods market, there is a money market, there is a labor
market. In the Keynesian model is much more cumbersome, I am doing it step by step,
not together. So, I will still have a short run model, where price are constant and I will
have two changes to the Keynesian cross model, one an investment function, two the
money market I will bring in. So, let us do one by one.
21. (Refer Slide Time: 54:30)
So, the changes in the goods market, let us focus on the goods market, the goods market
now if you recall the goods market clearing condition, recall the clearing condition or
equilibrium condition. Here in the goods market what was that, it was output is equal to
demand or supply is equal to demand and where demand had three components,
consumption plus investment plus government expenditure.
Now, I am not going to have I naught, I am going to have an investment function. So, I
would retain the government expenditure thing as autonomous, but I will have an
investment function. As I said there on that part of the world and C as before, plus C into
Y minus t Y plus T f as before consumption function, but I will assume to be a function
of r, where I r the first derivative is negative.
That means real rate of interest goes up, investment would fall in a country you saw that
from marginal productive of capital etcetera, because if real interest rate goes up that is
the rental cost of capital is going up, real rental cost of capital. Than is more costly for
company to investment.
So, they would stop investment at a high level of marginal productivity, where marginal
product from capital after investing matches with the cost. So, returned match is the cost,
otherwise it will not. So, it has a universal relationship, r goes up investment falls in a
country, r goes down investment goes up in a country. I was talking about the capital
demand function and all that marginal productivity of capital, all that explains that. So,
22. this is the goods market clearing condition, if that is true than I have the following thing
also.
(Refer Slide Time: 57:05)
Therefore, Y is equal to sum a naught plus C into 1 minus t Y plus I r, where A naught is
equal to C naught plus G naught plus, I think c T f naught, these are the three
components. Now, you are in this equation, the left hand side is supply, the right hand
side is demand. This is what I am writing, D contains these things. On the right hand side
equilibrium is supply is equal to demand. Now, you can imagine, just imagine the
following. Suppose, real rate of interest goes up what will happen? I r will fall, I r is
negative. So, I will fall, not I r, I will fall if r goes up [FL]. Therefore, the output the
economy is producing is now greater than demand, because the demand will fall given
other things remaining same. If I falls, I is on the right hand side.
So, the equation does not match, no more equilibrium Y is greater than demand. Demand
has fallen what do the company see in terms of unintended changes in inventories,
positive pick [FL], demand [FL], economy [FL] this all. Therefore, implies that delta I N
V U are inter inventory changes are positive. So, what would companies do? What
would companies do then lower output. This means companies would have to lower
output, [FL] they are not being able to sell what they are producing until now.
So, they have to adjust their production plans, if this persists they have to lower their
output right and if Y is load. Therefore, economy reaches a new equilibrium, so the new
23. equilibrium will be reached with the lower level of demand and lower level of output,
new equilibrium in the economy. In the goods market there will be a new equilibrium in
the goods market, there will be a new equilibrium. In the goods market have you
understood this, is it clear now? So, when r has gone up a lower level of Y.
(Refer Slide Time: 01:00:41)
Therefore, note that r and Y are inversely related for goods market equilibrium. Hence, I
can draw a diagram where I can have Y here and r here and will have a downwards
sloping line, where on this line all points satisfy goods market equilibrium. If r goes up Y
should go down and reach goods market. If r falls, Y can go up and we reach goods
market equilibrium. This is known as the IS curve, I stands for investment, S for savings,
I is equal to S in the classical model, you have seen after that it changed.
So, when professor Hix was writing, this paper he essential had the classical goods
market and what changes it has taken place when you shift to over to the Keynesian
frame work. In the classical frame work what was the goods market saving is equal to
investment. So, you called that IS curve and in the IS curve it was not meant for the
classical market. It was meant for the Keynesian market, Keynesian goods market
because these equation are not there in the classical model, but still use the word IS
because the corresponding part in the classical model had INS equality as an important
algebraic description of the goods market. Clearing condition I is equal to S, if you open
your classical economics note that is the macro model you will find that.
24. So, he called it IS although this is not the classical saving is equal to investment is much
more complex. It is the goods market clearing condition with consumption function,
investment function, government which was not there in the classical mode. Therefore,
on this model now if I ask you a question, you will understand these things very well. If I
take a point like a what is the problem with point a point A is a disequilibrium point is
not on the goods market clearing on IS curve.
So, what kind of a disequilibrium you have if you look at it from the point of you. How
far away the Y is? You see the Y is very much, if you take a IS point equilibrium Y is
very much in the access. If you take the rate the of interest than you come down and you
see the rate of interest is too high compared to where it should be for goods market.
Clearing goods market equilibrium rate of interest should come down and output should
reduce, you are too far away.
So, that point a what kind of disequilibrium you have, you have too much of output or
too little of demand because rate of interest is too high. So, investment demand is very
low rate of interest should come down and investment demand should go up. So, you are
here you have a typical situation where Y is greater than D, which means there is excess
D supply in the goods market, too much is supply in the goods market. Demand is down,
excess supply in the goods market. Furthermore, if there is excess supply in the goods
market you can also conclude that delta I N V U is positive, companies are stock piling
increasing their inventory stock because they cannot sell it excess supply [FL].
Similarly, if you have a point like B what is it saying either output should increase
towards IS curve, when you reach equilibrium or rate of interest should increase to reach
IS curve and reach equilibrium, Y is equal to D. That means at this point B, you have too
little output compared to demand, demand is too high should go up. So, investment
demand would fall and demand should shrink, demand is too high.
Now, compared to output, so you have here an excess demand situation so that B what
you have is essentially Y is less than D, which means excess demand in the goods market
and delta I N V companies inventories because of excess demand is all continuously
declining because it has to take the stock out from the inventory and meet the market
demand bringing it out and bringing it in market demand just offers it.
25. So, delta I N V is less than 0. So, above the IS curve to the right, you have excess supply
below the IS curve on the left, you have excess demand situation. These are both
disequilibrium regions. The equilibrium region is only along the IS curve where at every
point the goods market is clear. Clear means in equilibrium no excess supply of demand,
no excess supply of goods, no excess demand for goods, Y is equal to D exactly match
[FL].
Y minus D is 0 along the IS curve, above the IS curve you have excess demand for
goods, excess supply of goods below the IS curve you have excess demand for goods,
remember? But this is a topic on IS LM. So, I have to bring in LM now, before I bring
LM excuse me before I bring LM, what I need to check is the slope of the IS curve. Can
anybody find out from the equation what is the slope of the IS curve? What is the slope
of the IS curve?
(Refer Slide Time: 01:08:48)
Besides function what is it slope, what will be the slope in terms of the using calculus.
What will be the slope of the function, what will be the slope of the function if we use
calculus, what is the expression D r D Y? So, what is D r D Y? Please find out D r D Y,
the slope of the function, what is D r D Y, how much is D r D Y in this function from
those algebra that you have on the board. You can easily find out D r D Y, how much is
it autonomous variables are when you differentiate their O, assume them to be 0. What is
26. D r D Y [FL], D r D Y, 1 minus 1 minus C into 1 into minus T divided by I r, will it be
positive or negative? Negative because I r is negative.
So, the IS line is downward sloping, tell me a couple of more things, what would happen
if G increases? Government expenditure increases what will happen to IS curve? The
discussion should begin with this equilibrium equation, if G increases A naught
increases, if a naught increases what you have a disequilibrium in the market. What kind
of disequilibrium supply, more than demand or demand more than supply, demand more
than supply. If demand is more than supply, how would you cure that disequilibrium by
increasing output.
So, how would the IS curve get effected if G increases? You have a disequilibrium, you
have a point on the new IS. It will shift a point on the new IS where demand is more. So,
you will have more output, also how would it shift right. It will shift to the right, will it
shift parallel or will it shift with the slope change parallel, very good. So, if G increases
the slope of the IS will not get affected, but it will shift parallel, same thing will happen
if autonomous consumption increases or trans of payments increase [FL].
Now, you tell if tax rate changes how would the slope of the IS will get affected, will it
shift parallel, say tax rate has increased what will happen to the IS curve? How will it
increase? How will it change if tax rate changes? How would the IS curve shift, there
will be an alteration, but how will it shift? It will become flatter, it will shift parallel, say
tax rate has increased. I am saying tax rate has increased, tax rate increases 1 minus T
false C into 1 minus T false, 1 minus C into 1 minus C increases.
So, how will it affect the IS curve? It will become steeper. So, the IS curve will become
like this. This orange or yellow line is the new IS curve, when tax rate increases it will
become steeper. If government expenditure increases it will shift parallel, if tax rate
increases than the IS curve will become steeper, right? Do you agree with me or not?
This is the parallel shift and the parallel shift is only when the tax rate increases and
when, sorry when government expenditure increases when tax rate increases. It become
backward shift, with slope change it will become steeper, agreed or not? Did you agree?
[FL] If you follow you would enjoy because now it becomes algebraic logical and very
can very interest, you would understand our macro economy world. The most useful part
27. is just beginning, this paper is a starting point of the, yes you have a question which one
you have not been able to understand, right? Backward shift [FL].
Now, it is alright [FL] line [FL] output movement steep [FL] backward, inverse
movement [FL], alright? I walk like this, now I am have an inward movement, alright? I
become like this, I bent tax rate [FL] [FL], tax rate [FL]. So, the may way a person walks
you can tell whether he is probably happy or not, you can say, alright? These are
nonsensical things, but what I am trying to say is have you understood. If the tax rate is
increase, it is become steeper means it has gone inwards and the slope has increased. In
absolute terms, in absolute terms the mode value has gone up, the mode value.
