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.
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
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 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.
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 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
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 defines key economic concepts like GDP, price indexes, and real GDP. It explains that GDP measures total output in currency terms, but rising prices can make GDP rise even if actual output does not change. To account for changing prices, economists use price indexes like the GDP price deflator. Real GDP divides nominal GDP by the price deflator to express output in constant base year prices, allowing more accurate comparisons of how output changes over time independent of inflation.
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.
GDP measures the total value of goods and services produced in an economy over a period of time. There are rules for computing GDP, such as only including the value of final goods and services and using imputed values for non-market goods and services. GDP can be measured nominally, using current prices, or realistically, using fixed base year prices to adjust for inflation. Real GDP is a better measure of economic activity as it accounts for changes in quantity rather than just price level changes. The GDP deflator shows the inflation rate by dividing nominal GDP by real GDP.
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 an overview of key macroeconomic concepts including Gross Domestic Product (GDP) and the business cycle. It defines GDP as the total value of final goods and services produced within a country in a given year, which can be measured using either the expenditure approach or the income approach. It also explains how to use price indices to adjust nominal GDP values for inflation and obtain real GDP in order to make accurate comparisons over time. Finally, it outlines the four phases of the typical business cycle: peak, trough, recession, and expansion.
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

Topics in this lecture:
1. Purchasing power
2. Inflation
3. Index numbers and the Consumer Price Index (CPI)
4. Problems with the CPI
5. Real and nominal wages and income
6. Real and nominal interest rates
We all have a sense of what “inflation” means… The prices that we pay for goods
and services are rising over time. The goal of this lecture is to carefully define the
concept of inflation and understand how it is measured. Along the way, we’ll
develop the idea of using an “index” that will allow us to distinguish changes in
nominal output and real output. This can be applied to national output (GDP) or to
firm-level output.
Why is an understanding of price changes and the “cost of living” an important
concept?
Understanding how prices have changed over time allows for some insight into
whether or not people are better off or worse off over time. For example, your
grandparents might lament the relatively high prices of certain goods or services
today compared to prices in “the old days”. In 1950, a new house could be
purchased for around $8,000. Most new cars could be purchased for less than
$2,000 and the price of a gallon of gasoline was less than 20 cents. Compared with
prices today, these prices are quite low. Do today’s higher prices mean that we are
worse off? Not necessarily. In 1950 U.S. per capita GDP was around $14,000.
2
Today it is well over $50,000. To decide whether the average person is better off
or worse off than in the past, we need to look at purchasing power.
Purchasing power is the value of currency in terms of its ability to be traded for
goods and services. In terms of the above example comparing the price of goods
and services in 1950 to those same prices today, we’d ask how far the average
income of 1950 went in terms of a consumer’s ability to purchase things compared
to today’s average income.
How do we compare values over time?
In order to help with comparisons of value over time, economists often rely on
index numbers. Index numbers indicate the value of something relative to a
baseline value. The baseline value is usually a number that makes mathematical
comparisons easy, like 100. A price index can be used to calculate the rate of
inflation to help understand changes in the cost of living over time. Other examples
include stock market indices like the Standard & Poor's 500 and the Nasdaq
Composite Index.
For example, the consumer price index (CPI) allows us to make such comparisons
for consumer goods. The CPI is a measure of the average cost of a standard

Colin Tan: Why Investing in Singapore is Still a Good BetiProperty Malaysia
The document discusses why investing in Singapore property over the next 3-5 years is still a good option. It outlines several factors that will support rising property prices such as population growth, a strong economy, government plans to transform Singapore, low interest rates, and low price disparities between mass and high-end properties. The document also discusses recent government cooling measures and argues they aim for sustainable growth, not lower prices. It concludes that fundamental forces will outweigh temporary measures and property prices will continue increasing in Singapore.
This document discusses nominal and real gross national product (GNP). Nominal GNP measures total output at current prices, while real GNP adjusts for inflation by using constant prices from a base year. To calculate real GNP, nominal GNP is divided by the GNP deflator, which is a price index that shows inflation. Comparing nominal and real GNP allows economists to distinguish between changes in output versus changes due to price inflation. Real GNP provides a more accurate view of economic growth by filtering out the effects of rising prices.
This document discusses price indices and provides details about the Wholesale Price Index (WPI) and Consumer Price Index (CPI) in India. It defines price indices as weighted averages of price relatives that track prices of goods and services over time. The WPI measures inflation at wholesale levels, while the CPI measures inflation experienced by consumers. The document outlines the methodology used to calculate the WPI and CPI in India, including selecting commodities, collecting prices, determining weights, and calculating index values.
This document proposes strategies to add value to Mindvalley, an info publishing company. It suggests implementing dynamic pricing by testing different price points for different customer segments based on geography, passion level, age, etc. It also recommends staggering content delivery by breaking courses into modules and delivering them over time instead of all at once to encourage continued consumption and repeat purchases. The document aims to demonstrate the author's strategic thinking abilities to help grow the company.
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 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

Gross Domestic Product
Erskine S. Walther, Ph.D.
GDP: Defined
GDP: The market value of all final goods and services produced in an economy in a specific period of time.
Market Value: The measurement is in current prices, this known as Nominal GDP or just GDP.
Final Goods and Services: Goods and services that have reached their final usage. They are not used to produce another good or service. Goods that are used in that way are Intermediate Goods.
Intermediate Goods and Services are those that are used as inputs into the production of other goods and services. There are not directly counted in GDP as their value is included in the value (price) of the final goods and services. Thus, counting them directly would double count the same output. However, if the intermediate good has not been sold, it is counted in GDP as inventory.
GDP Defined: continued
Specific Period of Time: GDP can be computed for a month, a quarter or a year. The most common measures are annually and quarterly.
Formal, Legal Markets: Only goods and services that are traded in formal, legal markets are counted in GDP.
Underground Economy: The underground economy is composed of economic transactions involving activities that are not legal activities in a given society. These are not included in GDP. Illegal drugs and illegal gambling are common examples.
Informal Economy: These are legal activities that do no go through formal markets. They are not included in GDP. Income not reported for taxation purposes or work done for barter are examples of informal economic activities.
Some authors include legal activities as part of the underground economy definition.
GDP Defined: continued
Household Production: Productive activities done in and for the household are not counted in GDP as there is no direct monetary payment for such activities. (If you give children an allowance for household chores that would be part of the informal economy. If you clean your own home, that is household production.)
Leisure Activities: Leisure activities that do not involve the purchase of goods and services are not counted in GDP.
Spending an afternoon with family and friends that does not involve buying goods or services would not be counted in GDP as no economic transaction has occurred.
A vacation involving paid activities does count in GDP as goods and services are purchased.
GDP: Purpose
The Purpose of GDP is to measure the total output of goods and services in any economy during a specific period of time.
GDP is Value Neutral: It makes no judgments regarding product quality or whether or not a good or service is “good” for you. Those judgments are left to the consumer who is assumed to be able to make intelligent decisions that reflect their own personal tastes, preferences and values.
Changes in GDP measure economic growth.
Economic growth is the increase in the output of goods and services in an economy over a specific period of time. This must b ...

Identify the uses of GNP in measuring the performance of our economy.
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.
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 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 discusses macroeconomic concepts and national income accounting methods. It contains lecture slides and explanations from a professor on topics such as:

Gross Domestic Product
Erskine S. Walther, Ph.D.
GDP: Defined
GDP: The market value of all final goods and services produced in an economy in a specific period of time.
Market Value: The measurement is in current prices, this known as Nominal GDP or just GDP.
Final Goods and Services: Goods and services that have reached their final usage. They are not used to produce another good or service. Goods that are used in that way are Intermediate Goods.
Intermediate Goods and Services are those that are used as inputs into the production of other goods and services. There are not directly counted in GDP as their value is included in the value (price) of the final goods and services. Thus, counting them directly would double count the same output. However, if the intermediate good has not been sold, it is counted in GDP as inventory.
GDP Defined: continued
Specific Period of Time: GDP can be computed for a month, a quarter or a year. The most common measures are annually and quarterly.
Formal, Legal Markets: Only goods and services that are traded in formal, legal markets are counted in GDP.
Underground Economy: The underground economy is composed of economic transactions involving activities that are not legal activities in a given society. These are not included in GDP. Illegal drugs and illegal gambling are common examples.
Informal Economy: These are legal activities that do no go through formal markets. They are not included in GDP. Income not reported for taxation purposes or work done for barter are examples of informal economic activities.
Some authors include legal activities as part of the underground economy definition.
GDP Defined: continued
Household Production: Productive activities done in and for the household are not counted in GDP as there is no direct monetary payment for such activities. (If you give children an allowance for household chores that would be part of the informal economy. If you clean your own home, that is household production.)
Leisure Activities: Leisure activities that do not involve the purchase of goods and services are not counted in GDP.
Spending an afternoon with family and friends that does not involve buying goods or services would not be counted in GDP as no economic transaction has occurred.
A vacation involving paid activities does count in GDP as goods and services are purchased.
GDP: Purpose
The Purpose of GDP is to measure the total output of goods and services in any economy during a specific period of time.
GDP is Value Neutral: It makes no judgments regarding product quality or whether or not a good or service is “good” for you. Those judgments are left to the consumer who is assumed to be able to make intelligent decisions that reflect their own personal tastes, preferences and values.
Changes in GDP measure economic growth.
Economic growth is the increase in the output of goods and services in an economy over a specific period of time. This must b ...

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.
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
- 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 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
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.
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
- 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 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.

OJP data from firms like Vicinity Jobs have emerged as a complement to traditional sources of labour demand data, such as the Job Vacancy and Wages Survey (JVWS). Ibrahim Abuallail, PhD Candidate, University of Ottawa, presented research relating to bias in OJPs and a proposed approach to effectively adjust OJP data to complement existing official data (such as from the JVWS) and improve the measurement of labour demand.
Confirmation of Payee (CoP) is a vital security measure adopted by financial institutions and payment service providers. Its core purpose is to confirm that the recipient’s name matches the information provided by the sender during a banking transaction, ensuring that funds are transferred to the correct payment account.
Confirmation of Payee was built to tackle the increasing numbers of APP Fraud and in the landscape of UK banking, the spectre of APP fraud looms large. In 2022, over £1.2 billion was stolen by fraudsters through authorised and unauthorised fraud, equivalent to more than £2,300 every minute. This statistic emphasises the urgent need for robust security measures like CoP. While over £1.2 billion was stolen through fraud in 2022, there was an eight per cent reduction compared to 2021 which highlights the positive outcomes obtained from the implementation of Confirmation of Payee. The number of fraud cases across the UK also decreased by four per cent to nearly three million cases during the same period; latest statistics from UK Finance.
In essence, Confirmation of Payee plays a pivotal role in digital banking, guaranteeing the flawless execution of banking transactions. It stands as a guardian against fraud and misallocation, demonstrating the commitment of financial institutions to safeguard their clients’ assets. The next time you engage in a banking transaction, remember the invaluable role of CoP in ensuring the security of your financial interests.

"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.
Vicinity Jobs’ data includes more than three million 2023 OJPs and thousands of skills. Most skills appear in less than 0.02% of job postings, so most postings rely on a small subset of commonly used terms, like teamwork.
Laura Adkins-Hackett, Economist, LMIC, and Sukriti Trehan, Data Scientist, LMIC, presented their research exploring trends in the skills listed in OJPs to develop a deeper understanding of in-demand skills. This research project uses pointwise mutual information and other methods to extract more information about common skills from the relationships between skills, occupations and regions.

(Refer Slide Time: 00:19)
So, I want to know the real value, so he spent 2 kgs of apple.
(Refer Slide Time: 00:28)
He spent at rupees 140 per kg is equal to rupee 280, that is the nominal income to it and
my nominal expenditure. The real expenditure is this total expenditure if I divide it by
2. prices, I get real expenditure or real income from his point of view which is 280 divided
by 140, 2 in this case. It is measured in term, so 2 kgs of apple in case of natural income,
therefore you can see what I have arriving at, and you need a measure of prices which
you would use to divide the national income. You get the real income real national
income, so we need a measure of prices; the problem is there are millions of goods and
millions of prices.
In fact one good is somebody pointed out in the very beginning whenever I was talking
about; we need to add the market price value of goods and throughout the year market
price keep on changing. What will you do which market price are you talking about, you
have to find out which one decide that, some time they take the average value some time.
They take the reprehensive value which is not necessary, average value they think the
Ahmadabad price is the most reprehensive one work.
There are prices higher and lower by the workers also the thing that this is the sufficient
decision the judgment, the uses we need not get into that point is there are prices and
even one good has many prices. So, how would you measure prices, this is what I am
going to get into because unless we know prices we cannot determine the real value.
Here, to get the real value, we need the prices total expenditure would not have done;
total expenditure is like total income.
So, if I have total income of the country, suppose I have national income using the
income method or market price valuation of GDP if I have that or market price
valuations of GDP. We need to have some measure prices to get the real value, what is
your question?
Student: If the prices rise by 30 percent, but my income has not changed, what is the
significance of this for real income?
Quite possible.
Student: What is the significant of real variable?
Significant of real variable measure, the real value you are absolutely right, my income
remain, the price gone up to real income has gone down. It is quite possible, these are the
things we need to know understand, you are absolutely right, the real income did not
3. increase are persons real income is really falling because of inflation that is the macro
economy problem. So, do not think it cannot happen I earned the same money income
six months back what I used to earn in the six month period prices have been gone up the
goods that I have prices. The goods that I buy those buy prices, it may not be the
countries price level that cares at an individual level.
Therefore, my real income has fallen because that may be at higher prices of the bread
and butter and the rice and wheat that we buy and the vegetables. My real income has
fallen, it is correct that is why inflations is worries is that your question.
Student: What is the significance of real income?
Louder.
Student: What is the significance of real income?
This is the significance of the real income, it measure the actual income level what else
can be the significance, more significant do you want what more significant do you want
regarding real income is true measure of an income. You just do not say as I pointed out
19,000 rupees cablecast made point is actually real term, how much game did he make is
significant because with 90,000 rupees. You may not be able to buy the goods 10 years
later that bought 10 years back, so that is the significant variables income. Now, what is
your problem, that was not the very good question, you were thinking of something do
not interrupt me.
There is in discussion hour we take it up you are interrupting me, do not interrupt me if
you do not have good questions in discussion hour we will take it up. So, the real income
is become very important, so people want to know that in a country national income have
grown in rupees terms. I want to know what is the real gain to the country say per capital
income have you heard a measure per capital income. It is simple total national income
divided by the population sides, now you see the per capital nominal income has gone up
good, but I really want to know per capital real income, how much it is gone up.
That would benefit that on an average, it as an a average measure that as mean
everybody has gain, but kind of average income how much as it increase in a India real
income again, real national income that is the issue. Now, I guess somewhere I have to
4. being this how can I begin this if you remember a few things I said that the few things, I
said is a things like GDP or GNP when it is just written, it means it is measure the
current market prices that you have heard all. Now, let me tell you a very interesting first
a very useful measure a real variable how it is ramp one very common approach to
measure real GDP or real GNP is the following one very common approach to measure
real GDP is the following.
(Refer Slide Time: 07:45)
Now, what is happening in nominal GDP in nominal GDP or in GDP what we usually do
is the following. If some goods at a particular current time period like this where i goes
from 1 to n P i t is the price of good i in time period t and Q i t is total amount of good
would i produce in time period t. So, that is what is GDP in the country produce by
whoever, it can be produce by domestics companies. It may produce by a foreign
companies, this is GDP that what I thought you in algebraic terms, now problem with
this is that even Q i quantity remains same, but most price if even if some quantities are
falling the prices have changed quite of rate.
Then, the GDP in the next current, next time period will be a large the number Q i
remains more all this constants and even some are fall lesser amount produce, but p I is
large, this speaking have grown up majority of goods. In the next period, GDP value be
higher, this is this is a misleading you, this is the misleading information output in the
economy has to grown up overall output, but it shows a large a number.
5. If you use a method like this in the real value, but current price are involved in the value
which is the more significant value, how much the country producing more Indian
aggregate terms Indian aggregate sense. Over the years, how much it has produced today
more than the previous year, how much was produce in the previous year more than the
year before that and how much was produce in the next year compare to this year.
If I have to have a maculate economics data set where I can have a look on a big screen
how is Indian GDP value real GDP value in which is actually Indian producing modified.
How much is producing is a very simple way we approached that problem, we agreed
with would be to keep this prices that is use measure the value alive. So, we cannot add
apple or orange, we cannot have number of cars number of they have to be converted to
in common unit where you need the money value or something. So, price is happening,
but suppose I tell you solution to this problem find out real term, how much more is
produced I can do case of one pickle goods we will use.
I tell the case of multiple goods just do not happens millions of producing the country, if
I keep the price, but my steel allows me to convert see the volume of automobiles and
fans and. Then, to the nominal value, I can add in a common unit, then I saw the
publicity because year after year very GDP value would be reflected to overall change in
the cube value and what the P is the head constant, this is called using the basis prices.
(Refer Slide Time: 12:58)
6. So, use it constant basis for the base period in which we compare the number in future all
time and constant, now all goods are still multiplied by the prices which existed in 1993-
95, that is also once the data is tried. Then, data period basis I can compute real GDP,
one can obtain which is known as constant instant. It is not GDP, I can obtain constant
GDP as sigma i equals 1 to n P 0 and then you have Q i t for t overall times. I tell you
that real GDP constant GDP and GDP at constant prices are interchangeably used. This
is what I am trying to tell you, the multiple course, the real GDP like this, it is low in
physical term because this is it is not meaningful.
One happens or origins, but you are this spectacular shirt, watch, pen everything they has
to be, but still this is what real life because if you check only the value we have changed
over time keep that in mind respective is the physical quantity. We have to defense the
real GDP this is called constant GDP and real and this very simple, but very effective
which need the prices constant.
So, you have to evaluate goods in the current or any time period, how much actually
produce in a centre in an industry multiply, why the price are existed this is series and
shown on the mega screen. Exactly, how Indian real output or real output whatever and
then and in which price is measured has been moving. It has been moved and it is not
going to confuse you or misinform you with respect to how much GDP changes, which
is very important from the constant, how much more the country is producing has the
goods. It is very important, this is what you look at using the GDP, I have said that this is
real GDP. Now, I can tell you the first numbers measured of prices is the following
method.
7. (Refer Slide Time: 17:17)
The first measure real GDP, simple example again, if nominal expenditure is equal to P
into Q. Then, the theory follows the price the nominal value divided by q cross multiply,
nominal value divided by real value. Now, I have real GDP here constant, I have
nominal GDP here, so what is the first important letter average price in the country, what
is the example prices in the country, price level like in the sea shore at any point of at
any particular place of it values. I do not do the point what is the point, now you have
various point various heights of wages you want the average wage. You have to find out
the total always at any point and form some extra we made, how we can do it? In this
case, nominal value is equal to P price good, therefore price is equal to nominal value
physical quantity.
What will be the measure of price vertex from this two variables nominal GDP which is
current price market price and constant GDP the nominal GDP divided by GDP. You
have the measure prices. You buy an analogy by analogy, these two examples, so
nominal value expenditure on apple price I report the price of apple; you divide the
nominal value expenditure by the amount of apples. Here, when you have the price in
this case, we usually have always upwards measure of prices in the country.
8. (Refer Slide Time: 20:03)
That emerges GDP deflator, the prices that emerges which is GDP which is nominal
GDP divided by constant GDP called GDP defect as named what is GDP d. It measures
some prices, measure of all prices the one thing you should know, it is this of multiples
where we have been discovered method or keep the base time from constant throughout
the series. Then, we get the constant GDP and apply, multiply cannot get GDP, apply
multiply system, we already have. Then, we have the GDP designer measure the prices
in the country, one thing is done, somewhere you see that is different GDP value says
you can see.
There may be foot note or a base period price is measured and you know how they
mention the price. It is very important by the base crises are if you the base period the
price value change you take as the base period, sometimes it existed another GF. Then,
you evaluate all output levels to numbers of all output series that is true to the price are
different in that year 1994 and evaluate and get if the modern GDP. Then, the whole
GDP because of prices are all different although physical quantity are same in all this
year prices are different GDP numbers are different the real GDP values.
So, always it is therefore, mandatory to write down when GDP or constant GDP, the real
GDP what is what they right is because see this is the way created you have the wave
better that is used etcetera. They gone used, but GDP within bracket 1991 - 92 is equal to
100. This is what they will write, what it means physical is 1001 GDP is the value is
9. GDP is constant GDP is in the base of numbers one this one is actually ninety one make
this simple solution multiply 91, 90 prices one is equal to 100.
In fact, you will see some year mentioned is equal to 100, what it means is that year
prices have been used as the basic prices. You check that magazines that what is that
please check that, how they write, so whenever real values are mentioned all the prices
are mentioned respect to the particular set of prices. Otherwise, GDP are current number
using the current prices. That is the only we have I made it clear anybody very important
thing I wrote.
So, if you look at the basic price, then actually there are been 5, 6 prices, since he
depends price initially 40 is the change somewhere between. Then, it changes to 60, 70,
80, 94, now it has changed in some part prices, so it is continuously shifting, if you shift,
please give us the back number also because in the back numbers 40 years back are in
1993 or 81 price.
Suddenly, we are using the current numbers, how is it economic if I have research or
whatever going to find what is called the between the series. Some numbers are using
some series and other numbers last ten years between this is the huge number. Suddenly,
it is been shift [FL], these are the data to collect was on the base of one current present is
these problem are in the base period. Some product may not have existed, then how will
you account for them in the current period coming to it early question, but you know this
base period. Now, in US they are not using the GDP different value or measuring GDP
this way base 3 price what they are doing every two success year.
They take the average difference again that which does not know pricing bank all the
way you getting, they get the average of the year of the current or any year. So, they used
what is known real GDP in US, they are using called chain weighted measure of the
GDP chain weighted measure of GDP. This is what they used for everything, the prices
more than it and number continuously price and they have to current GDP is also GDP.
There are two years having the small changes whatever happen GDP, this is what they
use, now I come to the question that is the how do we measure and how to measure
prices.
GDP can be published once a year once you have all the values of output it takes the
long time. So, GDP reflected cannot be published data every week, it is very difficult, so
10. how do we measure prices and therefore, how do we measure inflation in India the way
we report there are two forms of measures in India. One is called CPI, other one is called
WPI in us the word WPI does not exists in US, it is called BPI what are the measure to
consumers price index how do exists and hopes the price index double index in US.
Also, price index have another name is called producer price index, so we are going to
talk about two most formula prices.
(Refer Slide Time: 30:21)
One is CPI, then and talk about another one which is known as WPI consumer price
index some people say economic say it actually does not just measured prices it
measures the cost of living of individuals. It has the very limited set of goods which are
called representative basket of the consumption of average consumer, if that is true, it is
the representative set of goods or basket average consumers. There are so many you can
ask this question, there can be average consumer go linear change in any constraint, there
average consumer of worker industry worker [FL].
They find the average consumer, it is very classic or they thought in middle family
average. So, there are so many average consumers, so basket of goods are that we
typically consumes in the week or a month or a year or whatever [FL], this much of
chemistry what they used whatever goods. So, CPI has fixed basket of goods that
represents average consumer in India is so diverse the rural side is different.
11. The urban side and the urban middle class is so different from what else, so what do you
find in India, there are three CPI majors. I can thank Indian government have one for
agricultural labor they call a l, then one for industrial worker price of it CPI [FL] and one
or the other like US upper income or lower income is called all that. So, these are three
CPI, so what they chose to do they find the measure of cost of living that is the price
movement of this typical three types of consumers in India which has rich or middle
whatever.
So, they constructed the representative baskets of goods that they consumes in terms of
quantity and they use the symbol the GDP differences that I used the index number, I
approach they use commonly. So, CPI is essential these typical baskets for any consumer
group of consumer and what you do is that you measures that in terms. So, one j is the
basket fixed basket of goods that the typical consumer same as the nominal divided by
real value, in case of multiple goods. The nominal value, the real value in terms of the
basic price, but the fixed cost is something.
So, there is no super script, here one going time period change what I do not have done is
nothing but the satiation deserves the right to change. The basket consumption that
changes and it forms the change physical composition of the basket of a carbon manual
or agricultural labor CPI basket and what will be the way does the a bounce the
changing. They can also change titans, they can drop some titans include something else
I can do that, but that entail is done only by the decision people would like we just look
at the numbers.
They do not look into all basket and output has changed how the CPI basket is revolved
go out workers in the past 50 years, how I change having the same quantities you want to
give change all throughout or q 1 is the different q 1. Now, the amount you want the
different amount what is the different amount I have the feeling that urban non manual
workers is not living in a city have very different of basket of concerns. When I look at
my kids they like food there is I stand over food with me 40 years, 50 years back, I did
eat that I had a very good food habit. These fellows at home is what they are happy, there
is no chapatti and rice, they are happy, I cannot imagine in dinner or lunch without rice
or chapatti food to buy such that they are happy.
12. These kids would not care, so foods habit has changed CPI baskets are might have
change the agriculture labor may not have change. So, that is the very interesting issue,
but I am not getting into that, I am not trying to take the conceptual frame of this term.
So, same method is used again the base period value would be 100 because you
multiplied and this 100 and you get a base period value. The issue is not kept it in term
of number which is expressed or not because you have since P 1 t, q naught 2 is the same
number into one the presentation. So, they are CPI series are 91 and 92 is a 100
published in India on a monthly basis, so this is the CPI value because these three
measures.
Now, I would conclude talking about price index briefly before I go into a comparison I
look after that, I just talk about the whole set price, and then going to the whole sale
price index the whole sale price index. If you want to look at the items including supply
some information as much longer items in a city in India number one is the same method
used. Once they have fixed, once they are fixed sometimes they may have a weight q 1 is
the type of goods was small you one a weight way make were one or that approved what
100 or whatever how you are express the weight.
So, they may not have so physical quantity method above that the type represent the type
of t kerosene q 3, now the weight attached alpha telling in that index in that index price,
how much weight is gain, how much involved is important. Depending upon the
consumer prices this is such an economic what is typical consumer’s preferences of
wheat type of oil they use etcetera. They were the various thing is going the wholesale
prices index very similar to this accept. They are longer set of number and the consumers
detect important is much this is the all as doing consumes there as consumers.
The goods that the consumers are called and then the fuel electricity cost etcetera and
then you have a bundle of raw material and semi finished goods of wholesale price and
the total list is like 200, 300 items. Everyone has the weight every goods has the weight
and weight does not point out, so they are all rated and the weight can change time to
time changes WPI. They are adjusted depending upon the important thing, so it would
process we should find out what is important in the country and by looking at that has
finished goods like CPI for primary goods any were electricity fuel etcetera cost in India.
13. Then, you have finished a semi finished raw material that means that one means industry
producers they are all included in it and whole large longer listed number. It is published
weekly that is every week data is collected from various corners and mostly probably as
the probably as people fixed it. They report the data on a particular date, they collect the
data they know where to collect they have decided already. They have to make the
average number put it in the computer to the US computer, but the thing is what is very it
is not talking about. So, there would be electricity cost and they will take final goods also
food items fruits etcetera industrial goods semi finished goods which industries used
assumption.
My assumption not final goods assumption, I got the CPI try to multiply what will
become CPI what will be the data remember is not present. So, it is very different WTI
letter, so the first I gave to the GDP which will be the same method of limited number of
goods CPI, WPI whole sale price index. One thing you have to notice compare to CPI, it
includes the number of industrial products just not consumer products, therefore this
price index is most relevant to industry, but consumer also pay attention to it. To be
honest with you the true price level that is relevant to consumer is real prices, but
newspaper etcetera journals the fashion.
The trend is you know the practice is not to report CPI value the cost of leaving for you
and me most important CPI value this somebody. Some economic students are doing a
project trying to find out this under my guidance means they come and concern me not
on the regular guidance bunch of people are doing some projects. They want to do
something I said, one of the fellows tow fellows have involve with this on the difference
in the numbers coming from CPI and WPI. The government when reports or talk about
inflation any discussion on TV on inflation, all is based on WPI value.
That has the largest audience which interest people on a wide scale, but to US consumer
the most important inflation or price index value would be CPI whichever CPI is relevant
because of that way cost of living, so the question is that WPI. Why this relevant, why
one thing includes industrial goods is relevant to industry goods, second this is the very
interesting inside into WPI useless. Since, WPI includes semi finished goods and raw
materials and quite to bit of it large chunk of it weighted is very high. The largest
weighted among the three groups in WPI is probably on this, and then there is
disadvantage of using the price index to predict the future.
14. Let me tell you this way if semi finished product and raw material price are going up
quite a bit if the stations observes that and that as the reflection WPI value level. Then, it
is indicating, these semi finish goods are raw material which are going to produce finish
goods tomorrow will also going to have a higher prices. So, it has the futuristic
component a continent it can be used to predict future price changes, CPI not necessarily
gives that it is only the finis foods price which may fluctuated for various reason, but in
this case the cost of living. If they are going the cost of input raw material cost etcetera
are going up, then for sure it can explain expect in future prices finish good will grow up.
There will be upward pressure inflation, so many economist say WPI is more useful than
CPI, but CPI is more useful to consumer to us, so I am concerned CPI, most relevant
value. So, whole sale price is index whole sale price index is a very interesting thing, it
has the futuristic component, it can be used through to predict the future what is going to
happen. It has so much of importance to semi finish goods and raw materials that if there
is measure change is in prices, then WPI would reflect that today, but also it is telling
tomorrow is going to be more price increase. This semi finishes goods raw materials
would convert and finish goods whose prices also will be higher naturally simple logic.
If cost are higher, the producer also raise the market price, but now I want do a
comparison between CPI and GDP well you are absolutely when you say somebody
pointed out that a GDP a base period price concept has some problems. I am coming to
that, first of all note that CPI compare to GDP is a discretion advantage because CPI is
selected, the very smalls of set of produce that are produce in the country which interest
the consumer. So, it has a very narrow objective to word serve the consumer and that to
they fix it year after year.
When they get the numbers well consumer reference chanced as I told you if you take a
long run view of 30, 40 years in my life for instance as I have seen consumer preferences
for instance shifting different kind of food have been etcetera. For loading reference, for
instance we use to go to Cinema Theater, you use to fight in the line get a ticket, you
want get a ticket stands in the line for 2 hours to get into movie theatre, who does it
today only. Anybody does this no consumer preference the sit at home watch TV. They
get a DVD, they get everything pirates cassette have DVD has floated the market any
film which is released the immediately pirates staff is out, I have seen preference are
shifted they goes to mall this days.
15. I never seen a mall in my life until recently, so GDP is much useful because GDP take all
goods into consideration and if you talk to talk about prices taking all goods into
consideration is the wonderful thing. Then, considering a very compensate price index
compressive major prices, so many people like GDP, the problem is since GDP includes
all goods where is the time to collect the data or all goods it takes the long time to take to
collect the data. When you talk about CPI in any countries, the matter of fact there is no
restriction on CPI to include imported goods because consumers like it imported goods
you take an African country, some country.
When they do not produce enough most of the things are imported if you take the small
country in Europe symbols Luxemburg for instant one of the richest country in the world
small country. They do not produce everything, they import more bulk things their CPI
would include imported goods, but if you talk about GDP reflector, GDP is all goods
produced within the country, these no imported content. So, imported goods would not
be there remember is another different that is coming, now the other point which I have
already mentioned the CPI is fixed and the GDP reflector is ready because every year
how much is produce taken into consideration.
There is something which is very important suppose there is to be CPI good number n or
j which has now disappeared from the market this year. There has been the crop failure;
however some amount of that output is still in the market on the shells because
somebody holed it. They have been sold the in the high price basically crop is not the
market, there was the crop failure the item is there in CPI because of fixity awaits. You
cannot remove it and normally high price is not measuring typical consumers
consumption if normally high price are there consumer is not typically consuming.
It is not there in the market, some rich people playing high price is alright say apples,
there was the apple has huge amount of there was the consumers preference. When it is
normally available, but if there is the crop failure a few basket available sold at a very
high price. It is not the typically consumer basket in case of GDP apple would not show
there crop failure thing, but in case of CPI since you fixed it and you do not change. It
will distort the price movement of CPI basket is another disadvantage of having fixed
rate in typical microeconomic theory.
16. We also say that when price is change when the price is change consumers have the
substitution effect where the substitution effect is, if prices of apple go up to much
consumers would look for substitute food product. Then, I go for bananas orange, even if
they do not like that much in winter, they will look for apples, but apple prices are too
high. They will substitute away, but if you fix the weight consumer preferences are not
reflected these changes seasonal changes yearly changes. It is the consumption basket
because the weight of fixed CPI is not a good measure; they will not reflect the
substitution effect. Now, I come to this point, there are 1980-81 for instant when I was
coming out university and trying to go for higher studies.
Around that time, there were no computers in India, so I remember how nervous I got
when I first saw the computer and I was given the assignment of the computer. I have
seen a computer I was asked to do the assignment on computer, how that I am going to
do, anyways those used to do. Now, imagine Indian output, no computer sold base period
is 1990 s when computers have come has entered in the market place what price I am
going to use to compute the real value of GDP because in 81 there was no computers, but
there were reporting numbers.
So, what they do is the question you had you were good exist in west period, but now it
exist and they would try to look for an international price convert that into Indian
currency price looking at similar goods if international price is such and such. So, much
demand of preference in the country what is the drafting Indian price which is the close
substitute in case of computer is possible, but in case of some other case, it may be
possible which existed in India those of that auto mobile what price would have been
there. So, statistician problem GDP conceptual frame talking about a lot, but the
statistician really has the final stage and also has the night mare of crunching the
numbers out these variables.
So, many compromises, so many assumptions, so many difficulties he has to finally get
the numbers for you, which we look at and say inflation is going up India, inflation is
good not such a bad number of after all. To come to that point, you many have that there
are many problems with these variables final point neither GDP nor CPI neither GDP nor
CPI. I take into consideration the qualities changes that as taking place, they only look at
the quantity that are produced a quantity is demanded how about the qualitative changes
taken place, TV used to be like this, TV price are fallen as quality has fallen.
17. When Quality has gone up, TV price are fallen does not means the TV has become less,
so qualitative changes in variable. So, what will you do in when the quality changes, it is
very difficult they do not accurate? So, they price level measures real variable measures
very crude still they have to make many assumptions the problems that just I pointed out
some case fixed goods basket are there. In some case, goods does not exist in the base
year some case qualitative changes are taking place in some cases there may be entire
crop failure the product is not there in the market, but just because it is there in the few
the shops. The prices sky rocketed are and some consumers are buying, it will distort the
numbers and still enters unless force fully you will take the number out.
All depends upon the statistician preferences to small point I am finding a variable to sit
here, therefore what is inflation rate any rate how will you calculate CPI value WPI, CPI
GDP deflector. What will be the inflation rate, what is the simple arithmetic measure,
simulation rate, how would the inflation rate measure percentage change in prices, why
is no answer there how is the growth rate is measured. How did I say the growth rate
measured, how is the growth rate of the variable measured, y t divided by y t minus equal
to 100, you can make the percentage change.
So, the inflation rate is how much CPI rate is how much CPI minus t into 100, this is
how inflation rate is measured in India WPI minus today value divide by minus WPI.
Yesterday, value into 100 percentage change is same thing in case of growth rate of
output growth rate prices and prices have been measured in price level which is price
indices consumer price index WPI whole sale price index. Then, you have GDP also
price index, this is how would you measure that inflation rate, but remember one thing
which people forget was suppose the price of the price of the some goods in year if I
draw the diagram.
18. (Refer Slide Time: 59:48)
This is the time period, and suppose CPI value I am measuring, CPI value was 100 here,
then for one time period to 1, 2, 3, 4, 5, 6 and 7. Suppose, one time period it remain the
same and then in seventh period it went up to a number which may be something like
100 to 200, 300, 400. So, you say this is 400 percentage inflation rate or something or
how much it will be 400 minus 300, 300 percent inflation rate. You say what is that is
not true because prices are remain constant priceless are remained constant for all this
periods.
Suddenly, it has gone up this is not inflation persistence rising prices, so in case of
inflation the line price line either like this or like this have reached that point or like this
have reached that point over time. So, every period there is some increase in prices either
in the concave shape convex shape or concave shape whatever or in a linear fashion. It
can also go up in a linear fashion the price can also go up in the linear fashion prices can
go up in the linear fashion.
So, come to that point, then you call that inflation, so persistence change in prices
upward is inflation change persistence is change in down ward if they falling they called
deflation, one is inflation. If it remains constant for a while the choke and then suddenly
jumps to the same height I am talking about the same height, it jumps inflation that is
how one short increases in price the two short increase in price. That is not called
inflation, so in India will be talking about inflation, if you notice is the persistence
19. increases in prices that you called inflation what you call one time increase in price one
shot change in price one time change in price or something 300 percent, 200 percent
whatever that is not inflation.
So, when India talks about inflation is a problem you will see that the talk about the
positive inflation rate every period no period is 0, 0, 0, 0 and suddenly 300 percent.
Every period they are talking about 7 percent, 8 percent and 12 percent, 13 percent
increasing prices nonzero increase that is why they talk about inflation as problem. Every
period there is nonzero change in price a positive point may be 4 percent may be 10
percent may be 12 percent, 8 percent that percent change may be going up and down, but
prices are increasing continuously.
I have CPI measured, this I do not have inflation rate measured here, I have CPI
measured here, what I am trying to tell you to this point. This point same change in
prices are taken place to n point, but one path is this one the white line the other one path
is any of this lines this pink cooler inflation problem in the country because CPI value is
increasing every period.
(Refer Slide Time: 01:03:54)
So, pi value which we call pi, it is measured in terms of pi, so the pi value is changing or
non zero, it may change, may not change may be constant, but non zero that means CPI
is changing continuously. So, you have CPI t minus CPI p minus 1 over CPI t minus 1 in
200 pi is inflation typical notation and economic for inflation is pi Greek alphabet phi
20. typical notation for all output in economic is small typical notation for price is P typical
notation for output is y. I have been using them already, but you will get with it, you will
get used to that the notation are always this the last point you remember unemployment
data define that unemployed total labor force.
I want to make one or two concluding remarks here that if a person is unemployed, he or
she cannot be discouraged worker sitting at home nit looking for job. I have friends
Kolkata did not get the job in 60s and 70s, I remember who would do nothing will not
even look for a job. Those people are not called unemployed, who are not looking for a
job or a discouraged worker a person who is unemployed is essentially looking for a job.
Actually, it is fit enough to work offer a job, but he is not finding the work remember
secondly part time workers are not counted as unemployed, part time worker are counted
as employed, although they have only half the job. There is no waited system in
unemployment calculation, if it is part time the one-third, remember that, so the part time
workers is not consider to be unemployed is consider to be employed. Although it is not
fully employed, the last point I want to mention is a very interesting thing a few point I
am going to mention and you can or man view a person is unemployed.
If he is a paid employed like me, I am paid by IIT, I am paid in employee, I am
considering to be employed, but all was own business also called employed. I am not
paid any anybody, I have my own shop, I am employed, there another very interesting
point I have, I get labor laws from vary from country to country. A person is also called
employed if he is unpaid family business, he is still employed, suppose your elder
brother business even he would not pay you asked to come there you spent time from
morning.
You do not get the salary, but you would considered as employed because you are
working there and of course if you are temporarily absent because of vacation or ill or
something you are not necessary unemployed. You were absent, but you are absent for
some reason that does not mean you become the student. So, you do not become
unemployed, if you are interest employment and unemployment and labor force is called
labor force participation rate is called labor force participation rate. A very interesting
labor force participation rate that is if this is the total count of labor force who are above.
21. The employable age is not a minor child worker the issue of child worker child labor
there are not suppose to be working, so they are not part of labor force, but it is the
illegal thing to do, child labor is called very important issue in the world. Many countries
do not buy form India, they think that Indian carpet industry, Indian handicraft industry
employed child worker. They do not want to buy goods from there, but a person who is
age who can work of the labor force, but does not mean necessarily that he is either
unemployed or employed. This is very much employed, but he is not part of the labor
force, so labor force participation something very interesting number is I will tell you
example. Suppose, I am an adult human being may be I have the degree like you from a
good place.
I can own business, I can get employed, but I decided not be a part of the labor force, I
prefer my wife should go out, I sit at the home and do the I raise my stop when I was in
college what happened. Basically, this couple decided to reverse the role because I have
been got unemployed. The wife started working and the man in the house started looking
up the kinds doing the house hold work doing the taking children to bed, putting them to
sleep, taking them to the school. All the mom’s work, the man is doing, his name was
mister mom, I am not joking, I have seen, I will tell you the you can search internet that
the details I am taking about 1980 film early 1980s, you will get the even.
I remember that, the actress, but I forgot the name, so in western country very interesting
this is happening which is actual data the labor force participation rate is more or less
study that is labor force the actively count or unemployed looking for the job. The labor
force participation rate and the male and female amazing trend in the western country
like us the male labor force participation is like a man curve going down many men
prefer to not work. After few years the female participation ratio has gone up a supply
curve and clearly there is the equilibrium like the demand supply diagram.
I thought my goodness what is diagram is then I paid attention to the table, this is greater
in man curve open deserve section and find if I am joking or not, they have actually
collected numbers labor force participation in the US, in India. It might happen
tomorrow, so much freedom from women and equality of women which is very, but you
cannot help it. You will find female participation ratio going up more female in the
ministry, more female members in the parliament more female in the police force, but no
female.
22. Unfortunately, all male are at home most male are at home in US, the data is showing
that go and check that book second chapter. You do not have to go to many later chapter
to search for it, so that is also another interesting number of which labor force
participation rate has to do with labor has unemployed etcetera.
Then, only calling unemployed anymore clearing the labor force, usually when do people
drop out labor force population when they are very young they are not part of labor
force. After retirement very old they are not part of the labor force in between say from
70 and 80 year to the 60 years. It should be part of the labor force, but where do you find
labor force participation, so what the hell are they doing this is what they are doing wife
is very happy earning because they do not earn enough.
That is why you have the women exploitation in labor country one of the reason is that
economically not independent. You have to dependent upon the man takes her for the
ride. So, women gets freedom economically, then it is much easier than I do not know
what else can happen, do not ask me.
