This presentation continues our analysis of the forces governing long-run economicgrowth. With the basic version of the Solow growth model with technological progress.
Unit - IV discusses production functions and the laws of production. It explains that a production function shows the relationship between inputs like labor, capital, land and the output produced. The laws of variable proportions and returns to scale are then covered. The law of variable proportions explains how output changes when one input is varied while others stay fixed. Returns to scale looks at what happens to output when all inputs change proportionately. Economies and diseconomies of scale are also discussed.
Macroeconomics is the study of the economy as a whole, including issues like growth, inflation, and unemployment. Economists use models to help explain and address these issues. Models make simplifying assumptions, like whether prices are flexible or sticky in the short-run. The chapter introduces concepts like endogenous and exogenous variables. It provides an example model of supply and demand for cars and how it can be used to analyze changes. The chapter outlines the topics that will be covered in the macroeconomics textbook, including classical theory, growth theory, and business cycle theory.
This document provides an overview of a macroeconomic model that examines national income. It discusses how total output is determined by factors of production like capital and labor. It then explains how factor prices, like wages and rental rates, are set through supply and demand in factor markets. The model shows how total national income is distributed to factor payments. It also outlines the components of aggregate demand, like consumption, investment, and government spending, and how their equilibrium in the goods market determines total output.
Methodology of Econometrics / Hypothesis Testing Sakthivel R
This document discusses key concepts in hypothesis testing in econometrics, including:
1) Hypotheses can be simple, specifying all parameters, or composite, specifying some parameters.
2) The null hypothesis is the initial hypothesis being tested, often of no difference. The alternative hypothesis is complementary to the null.
3) Data can be collected through sampling, experiments, or other sources and is either primary or secondary.
4) Hypothesis testing involves statistical procedures to decide whether to accept or reject the null hypothesis. If accepted, the theory can be used for forecasting, prediction, or policy recommendations.
The Philip curve shows an inverse relationship between the rate of unemployment and the rate of change in money wages in the short run. Friedman argued that in the long run, there is no tradeoff between inflation and unemployment - the Philip curve becomes vertical at the natural rate of unemployment, which is the rate where expected and actual inflation are equal. Temporary reductions in unemployment below the natural rate are only possible if inflation rises above expectations, but eventually expectations will adjust and unemployment will return to the natural rate, even as inflation accelerates.
This document discusses the natural rate of unemployment and its causes. It begins by defining the natural rate of unemployment as the average rate around which the actual unemployment rate fluctuates over the business cycle. It then presents a model showing how the natural rate is determined by the rates of job separation and job finding. Frictional unemployment results from the time it takes to search for and transition between jobs, while structural unemployment stems from wage rigidities that prevent wages from adjusting downward to clear the labor market. The document explores factors like minimum wages, unions, efficiency wages, and sectoral shifts that contribute to real wage rigidity and the natural rate of unemployment.
This document provides an overview of classical macroeconomic theory. It discusses how classical economics emerged as a revolution against mercantilism, emphasizing free markets and real factors of production over money and trade balances. Key aspects of classical theory covered include:
- Labor and capital markets clear through price adjustments to equilibrium.
- Firms maximize profits by equaling marginal revenue product to factor prices.
- Production depends on labor, capital and technology. Increases in these real factors of supply are what increase output.
- Money is neutral, having no long-run impact on real variables like output and employment.
The Harrod-Domar growth model uses 3 key variables to determine the growth rate:
1. The saving rate, which determines how much can be invested.
2. Capital productivity, or how much output increases with each unit of new capital.
3. The depreciation rate, which accounts for aging of the existing capital stock.
The model's formula is: Growth Rate = Saving Rate x Capital Productivity - Depreciation Rate. It provides a simple framework for analyzing how changes to these variables impact long-term economic growth.

Ordinary Least Squares (OLS) is commonly used to estimate relationships between variables using observational data in economics. OLS finds the line of best fit by minimizing the sum of squared residuals to estimate parameters. The OLS estimator is a random variable that depends on the sample data. Asymptotically, as the sample size increases, the OLS estimator becomes consistent and its variance decreases. OLS provides the best linear unbiased estimates under the assumptions of the linear regression model.
This document provides an overview of classical theories of inflation and the quantity theory of money. It defines key concepts like money, inflation, the money supply, and velocity. The quantity theory of money posits that inflation is primarily caused by increases in the money supply that outpace economic growth. It predicts a direct relationship between money growth and inflation. The document uses graphs and international data to show this relationship generally holds in practice and discusses implications for interest rates.
Lecture slides for an undergraduate course on Basic Macroeconomics that I taught in the Fall of 2007.
This lecture introduces national income accounts.
This chapter discusses recent advances in business cycle theory, including Real Business Cycle theory and New Keynesian economics. Real Business Cycle theory assumes flexible prices and that fluctuations result from optimal responses to productivity shocks, while New Keynesian economics focuses on explaining price stickiness through microeconomic factors like menu costs. There is ongoing debate around the assumptions and empirical evidence regarding both approaches.
Meeting 5 - Leontief Paradox (International Economics)Albina Gaisina
Leontief attempted to empirically test the Heckscher-Ohlin theory that predicted countries would export goods intensive in their abundant factors and import goods intensive in their scarce factors. However, his analysis found the opposite - that the US exported labor-intensive goods despite being capital abundant. This contradiction became known as Leontief's paradox. Explanations for the paradox included differences in labor productivity between countries and the oversimplification of excluding natural resources. Later studies by others found similar paradoxical results for other countries like Japan. The paradox led some economists to dismiss the Heckscher-Ohlin theory in favor of models based on technological differences.
General Equilibrium IS-LM Framework for Macroeconomic AnalysisKhemraj Subedi
The document summarizes the IS-LM model of macroeconomics. It explains that the IS curve represents equilibrium in the goods market where investment equals savings at different interest rate and income level combinations. It slopes downward to show that lower interest rates lead to higher investment and income. The LM curve represents equilibrium in the money market where money demand equals supply at different interest rate and income level combinations. It slopes upward as higher income increases money demand, requiring higher interest rates to equilibrate the money market. The IS and LM curves intersect to determine the general equilibrium interest rate and income level in the short run.
This document provides an overview of circular flow models in economics. It begins with defining the circular flow of income as the circulation of money, goods, and services between producers and consumers. It then covers the two sector model which includes households and firms exchanging money for goods. It introduces the three sector model which adds the government sector that collects taxes, spends on goods/services, and provides transfers. Key points are explained through diagrams and the document signifies how these models underpin national accounting and macroeconomics.
The Bergson social welfare function was introduced to provide a scientifically normative study of welfare economics. It defines social welfare as a function of the welfare of each member of the community, depending on factors like their consumption and services. The function establishes a relation between social welfare (W) and the utility levels (U) of each individual (U1, U2, etc.), representing social welfare as an increasing function of individual utilities. It assumes social welfare depends on individual wealth/income and distribution of welfare, and allows for interpersonal comparisons of utility. However, the concept has been criticized for not applying to all governments, being difficult to construct, arbitrary, and not empirically significant or helpful for solving problems.
1. The document discusses using the IS-LM model to analyze the effects of shocks, fiscal policy, and monetary policy. It provides examples of analyzing different policy changes using the IS-LM diagram.
2. It then discusses how the IS-LM model can be used to derive the aggregate demand curve and analyze short-run and long-run effects of shocks. Price level adjustments move the economy from short-run to long-run equilibrium.
3. The document contains an example analyzing the 2001 US recession using the IS-LM framework, examining the effects of stock market decline, 9/11, accounting scandals, and fiscal and monetary policy responses.
Supply-side economics believes that high tax rates in the 1970s slowed economic growth. Supply-siders argue that lowering tax rates will increase incentives to work, save, and invest, leading to higher output and tax revenues in the long run. However, the relationship between tax rates and revenues depicted by the Laffer curve is uncertain, as it is difficult to know the precise tax rate that maximizes revenue. Additionally, the impact of tax changes depends on the time horizon considered, as adjustments to incentives take time.
This document provides background information on John Maynard Keynes and his development of Keynesian economic theory. It discusses Keynes' life and education. It then summarizes Keynes' vision, which rejected classical assumptions about full employment and Say's Law. Keynes argued that aggregate demand, not supply, determines output and employment. The document also provides accounting identities that define equilibrium in the Keynesian model and Keynes' initial assumptions about price and quantity adjustments.
The marginal productivity theory of distribution Prabha Panth
The document discusses the neoclassical theory of distribution and the concept of factor payments. It addresses the "adding up" problem of whether total factor payments will equal total product. Wicksteed showed that under constant returns to scale and factors paid their marginal products, total revenue will equal total costs through Euler's theorem. However, this assumes a linear homogeneous production function. Later economists like Samuelson and Hicks found the condition is only met at the minimum point of the long-run average cost curve, where a firm has constant returns to scale.
Regulation and control refer to government intervention in markets through various policies. There are several rationales for regulation, including addressing market failures from natural monopolies and externalities. However, regulation also imposes costs. When competition is eliminated and a monopoly is formed, either private or public, welfare loss occurs as output is restricted and prices rise. Resources also may be wasted in "rent-seeking," which refers to efforts to capture wealth transfers from the government, such as through lobbying for regulations that create monopolies, tariffs, quotas, or subsidies.
INDIRECT UTILITY FUNCTION AND ROY’S IDENTITIY by Maryam LoneSAMEENALONE2
- Utility is a measure of satisfaction derived from consuming goods and services. Individuals seek to maximize their utility subject to a budget constraint.
- Indifference curves represent combinations of goods that provide equal utility. The slope of the indifference curve is the marginal rate of substitution (MRS).
- The budget constraint shows affordable combinations given prices and income. Utility is maximized at the point where the MRS equals the price ratio, where the indifference curve is tangent to the budget constraint.
- Using tools like Lagrangian optimization and the envelope theorem, the amounts demanded of each good can be derived as functions of prices and income.
This document provides an overview of the Solow growth model, which examines how economic growth and standards of living are determined in the long run. It introduces key concepts such as the production function, saving rate, depreciation rate, capital accumulation, and steady state. The steady state is the level of capital where investment just offsets depreciation and capital remains constant. The model predicts that countries with higher saving and investment rates will have higher levels of capital and income per worker in the long run. It also discusses finding the optimal saving rate and capital stock, known as the Golden Rule, which maximizes consumption.
The Mundell-Fleming model is an extension of the IS-LM model that accounts for an open economy with international capital flows and exchange rates. It shows how fiscal and monetary policy can affect output and exchange rates under both fixed and flexible exchange rate regimes. Under flexible exchange rates, expansionary domestic policies may be offset by currency appreciation, while under fixed rates they may lead to balance of payments deficits. The model suggests using different combinations of fiscal and monetary policies to achieve objectives like boosting output while maintaining a stable currency value.
1. The document discusses general equilibrium theory (GET) and defines general equilibrium as a state where all markets and decision-making units are in simultaneous equilibrium.
2. It presents a simple two-sector general equilibrium model of an economy with two consumers, two goods, and two factors of production. Equations represent consumer demand, factor supply, factor demand, good supply, and market clearing for goods and factors.
3. With the number of equations equal to the number of unknowns, a general equilibrium solution exists in this Walrasian model under certain assumptions. GET provides a framework for understanding the complexity of economic systems through interdependent markets.
This chapter discusses the determination of national income and its distribution in a closed economy. It introduces the production function and factors of production, capital and labor. It explains that total output is determined by factor supplies and technology. Factor prices, the wage rate and rental rate, are determined by supply and demand in factor markets. Total income is distributed to factors based on their marginal products. The chapter then covers the components of aggregate demand - consumption, investment, and government spending. It presents the loanable funds market model to show how interest rates adjust to equilibrate saving and investment.
This chapter discusses two modern theories of business cycles:
1) Real Business Cycle theory assumes flexible prices and that fluctuations result from optimal responses to productivity shocks.
2) New Keynesian theory explains why prices and wages are sticky in the short-run, causing recessions as coordination failures when firms do not lower prices together. It incorporates insights from both schools to better understand economic fluctuations.
National income is generated as households supply factors of production to firms and firms supply goods and services in return. Factors of production earn income which contributes to national income.
The circular flow of income shows how income and spending flow between households and firms. Income from the sale of goods leads to more spending, which generates more income and spending in a continuous cycle. Savings, investment, taxes, government spending, imports and exports can inject or withdraw from the circular flow and influence national income.
Nuclear family, also called elementary family, in sociology and anthropology, a group of people who are united by ties of partnership and parenthood and consisting of a pair of adults and their socially recognized children. Sometimes, not always, the adults in a nuclear family are married and such couples are most often a man and a woman.

This chapter discusses the determination of national income and its distribution in a closed economy. It introduces the production function and factors of production, capital and labor. It explains that total output is determined by factor supplies and technology. Factor prices, the wage rate and rental rate, are determined by supply and demand in factor markets. Total income is distributed to factors based on their marginal products. The chapter then covers the components of aggregate demand - consumption, investment, and government spending. It presents the loanable funds market model to show how interest rates adjust to equilibrate saving and investment.

The document provides an overview of the Huli people, an ethnic group native to Papua New Guinea. It describes that the Huli are the largest ethnic group in Hela Province, with a population of around 90,000 people. They are known for their elaborate hairstyles and wigs, which can take up to six months to create. The document outlines aspects of Huli culture such as their traditional costumes, food sources, spiritual dances and ceremonies, and belief systems. It also notes that they live in villages separated from other groups and have a history of fighting among themselves.
This document provides an overview of agriculture in Bangladesh. It outlines that agriculture is the backbone of Bangladesh's economy, providing employment to around 48% of the labor force and contributing about 19.29% to GDP. The document discusses key agricultural statistics for Bangladesh and examines the importance and challenges of the agriculture sector, including problems related to climate change, population growth, and lack of modern machinery. It also reviews the various government agencies and organizations involved in the agriculture sector in Bangladesh.
Gross Domestic Product (GDP) consists of consumer spending, investment expenditure, government spending and net exports hence it portrays an all-inclusive picture of an economy because of which it provides an insight to investors which highlights the trend of the economy by comparing GDP levels as an index. It is used as an indicator for most governments and economic decision-makers for planning and policy formulation. In case of GDP, each component is given the weight of its relative price. GDP helps the investors to manage their portfolios by providing them with guidance about the state of the economy. Calculation of GDP provides with the general health of the economy. A negative GDP growth portrays bad signals for the economy. When the economy is expanding, the GDP growth rate is positive. If it's growing, so will businesses, jobs and personal income. If the GDP growth rate turns negative, then the country's economy is in a recession. It is not a measure of the overall standard of living or well-being of a country. Although changes in the output of goods and services per person (GDP per capita) are often used as a measure of whether the average citizen in a country is better or worse off, it does not capture things that may be deemed important to general well-being. Without an increase in GDP, there are always going to be limitations to economic development.

The document discusses technological progress in economic growth models. It introduces an endogenous growth model where the rate of technological progress is determined within the model rather than assumed constant. It also discusses policies that can promote economic growth, such as increasing the savings rate, allocating investment efficiently among different types of capital, and encouraging innovation. Empirical evidence generally confirms predictions of the Solow growth model.
Advanced And Contemporary Topics In Macroeconomics ISandra Long
This document outlines a course on advanced macroeconomics topics including the Solow-Swan neoclassical growth model. It provides an overview of the course content, which includes lectures on the Solow-Swan model, Ramsey-Cass-Koopmans model, endogenous growth models, and real business cycle models. It also lists relevant reading materials and outlines the course assessment including papers, presentations, and exams. The first lecture introduces the Solow-Swan model and covers its assumptions, production function, dynamics, impact of savings rates, and empirical applications to growth accounting and convergence analysis.
1) The simple growth model contains 5 main equations that relate key economic variables like investment, saving, capital stock, labor force, and output.
2) The aggregate production function shows that total output is a function of capital stock and labor force. As capital stock and labor increase, output will also increase.
3) Saving is determined by the saving rate multiplied by total income. Investment is equal to saving in a closed economy where saving must be used for investment or consumption.
The document analyzes economic growth in Darkhan-Uul province from 2000-2017. It finds that GDP grew at an average annual rate of 11.3% over this period, driven primarily by increases in labor productivity rather than employment. The economy transitioned from agriculture to industry and services, with services becoming the largest sector. Labor productivity accounted for over 50% of GDP growth, with the remaining growth from increased employment. Multiple factors influenced growth, including higher labor productivity, more days worked per employee, and increases in population and the labor force.
This document summarizes the results of a study on long-term changes in Spain's employment structure from 1977 to 2013. The study found that Spain experienced modernization, with a shift away from agriculture and industry towards services. Housing and construction boomed then declined. The welfare state expanded significantly. During economic crises, employment became more polarized, with job losses concentrated in middle-income occupations and gains at the top and bottom. However, polarization was small relative to overall employment trends and limited to recession periods. The findings suggest technology is not the sole driver of labor market changes.

This document examines the sources of structural change in the Indian economy from 1951-52 to 1983-84 using input-output tables and the Chenery-Syrquin model. It finds that non-proportional growth was largely due to technological change and import substitution from 1951-52 to 1983-84, with import substitution playing a dominant role in the 1950s-1960s. Export expansion contributed little to structural change. At the sectoral level, traditional sectors like agriculture and textiles grew at less than the proportional rate, while non-traditional sectors contributed more to structural change.
This document provides an outline and overview of growth theory. It discusses the empirical picture of economic growth, including some stylized facts about growth rates, capital intensity, returns, and income distribution over time. It also examines convergence across countries and uses growth accounting to measure the contributions of capital, labor, and total factor productivity to output growth. The document reviews relevant literature on these topics and provides empirical examples and results.
This document summarizes a thesis that analyzes the Beveridge Curve at multiple levels. Chapter I provides a theoretical introduction to the Beveridge Curve. Chapter II analyzes the Beveridge Curve for 19 OECD countries from 1980 to 2004, investigating the effects of technological progress and globalization. Chapter III analyzes the Italian regional Beveridge Curves from 1992 to 2009, examining the impact of atypical jobs on matching efficiency and spatial interdependence between regions. The author uses various econometric techniques to estimate dynamic panel models and test for shifts in the Beveridge Curve due to institutional variables, globalization, and technological progress.
Engineers play a crucial role in a country's development by designing infrastructure and producing goods and services to raise the economy and standard of living. Development involves transforming traditional societies into modern, high-productivity nations with manufacturing and service industries. The objectives of development are to improve sustenance, increase self-esteem and freedom of choice by widening access to life's necessities. Countries are assessed based on economic indicators like GNP and GDP, social indicators like education and health, and science/technology levels. Engineers contribute to development by building infrastructure and industries in developing countries.
The classical theory of Economic DevelopmentSharin1234
The Classical theory of economic development is the sum total of all theories of classical economists. The views of Adam Smith, Malthus, and Mill on Economic development form the crux of the classical theory of development. Though they differ on a number of development issues, the essence of the classical approach to development is the same.

This document discusses the future of lean construction in the Ethiopian construction industry. It provides context on the development of the construction industry in Ethiopia. The construction industry faces challenges in meeting cost, time, and quality targets. Lean construction has been shown to improve performance in other countries. The document assesses the level of awareness and potential benefits and barriers to implementing lean construction principles in Ethiopia. It is found that professionals have some awareness of lean construction, and potential benefits include improved productivity, sustainability, customer satisfaction, and reduced schedules. Key barriers are expected to be lack of knowledge, industry support, and resistance to change.
This chapter introduces economic growth and development concepts. It discusses Malaysia's strong economic performance from the 1950s-1990s driven by foreign investment and incentives. GDP grew annually by 9% from 1990-1996. Economic development also requires socioeconomic and technological changes to improve living standards. Islamic economics focuses on moral/ethical growth alongside physical/environmental development. The Malaysian economy transitioned from agriculture to manufacturing and services, with manufacturing contributing 30.9% of GDP by 2000.
Global trends in technology and industryrachit7sharma
The document discusses the relationship between changes in technology and industry, and their impact on economics. It provides examples of how certain technological innovations from the past, such as the transistor, had impacts on the economy that were only realized decades later. While changes in technology and industry do not always immediately impact the economy, over the long run they tend to have significant effects by transforming economic structures and activities. Key technological revolutions of the past, like the Industrial Revolution, have driven major economic transformation by increasing productivity and production.
The CIPD is focused on researching three core themes around the future of work: 1) the changing nature of work including trends in skills needs, career patterns, and new ways of working, 2) the diverse and changing workforce including demographics, generational shifts, and changing skills needs, and 3) the evolving workplace including organizational culture, employee engagement, and how people are developed and managed. The purpose is to understand trends shaping the world of work in order to improve practices and advocate for policies that benefit individuals, businesses, and society.
1. The document discusses the difference between economic growth and development. Growth refers to increases in production, while development encompasses improvements in living standards.
2. It examines factors that influence economic growth according to neoclassical growth models, including capital accumulation, technological progress, savings rates, and human capital. The Solow and Romer growth models are described.
3. Empirical evidence suggests that differences in total factor productivity and institutional quality best explain variations in growth between rich and poor countries. Geography and institutions have significant impacts on development.
This document provides an overview of key concepts in macroeconomics including:
- National income is determined by the production function based on the fixed supplies of capital and labor.
- Factor prices like wages and rental rates are determined by supply and demand in factor markets and will equal the marginal product of each input.
- Total income is distributed to capital and labor based on their marginal products.
- Aggregate demand is determined by consumption, investment, and government spending functions.
- Equilibrium in the goods market occurs when aggregate demand equals supply as determined by the production function.
- The loanable funds market equilibrates through adjustments in the real interest rate to equalize saving and investment
This document discusses the four sectors of economic activity: primary, secondary, tertiary, and quaternary. It provides examples of jobs that fall under each sector, such as farmers, miners, and steel workers for primary and secondary. The document asks students to categorize additional jobs, describe how employment varies by country, and analyze how the UK employment structure has changed over time from 1700 to 2050, noting key events like industrial revolutions, world wars, and technological growth.

5 Tips for Creating Standard Financial ReportsEasyReports
Well-crafted financial reports serve as vital tools for decision-making and transparency within an organization. By following the undermentioned tips, you can create standardized financial reports that effectively communicate your company's financial health and performance to stakeholders.
A toxic combination of 15 years of low growth, and four decades of high inequality, has left Britain poorer and falling behind its peers. Productivity growth is weak and public investment is low, while wages today are no higher than they were before the financial crisis. Britain needs a new economic strategy to lift itself out of stagnation.
Scotland is in many ways a microcosm of this challenge. It has become a hub for creative industries, is home to several world-class universities and a thriving community of businesses – strengths that need to be harness and leveraged. But it also has high levels of deprivation, with homelessness reaching a record high and nearly half a million people living in very deep poverty last year. Scotland won’t be truly thriving unless it finds ways to ensure that all its inhabitants benefit from growth and investment. This is the central challenge facing policy makers both in Holyrood and Westminster.
What should a new national economic strategy for Scotland include? What would the pursuit of stronger economic growth mean for local, national and UK-wide policy makers? How will economic change affect the jobs we do, the places we live and the businesses we work for? And what are the prospects for cities like Glasgow, and nations like Scotland, in rising to these challenges?
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.

Suzanne Spiteri’s recent report on improving the quality and accessibility of job postings to reduce employment barriers for neurodivergent people.
Decoding job postings: Improving accessibility for neurodivergent job seekers
Improving the quality and accessibility of job postings is one way to reduce employment barriers for neurodivergent people.
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.

• Technological Progress in the Solow Model
• The Efficiency of Labor
• The Steady State with Technological Progress
3. INTRODUCTION
• Macroeconomics tend to adopt more approaches, with models
often being developed with the intention of helping to explain
one particular aspect of macro economy.
• The first model that will a model of economic growth.
4. SOLOW GROWTH MODEL
• The Solow growth model is a
standard neoclassical model of
economic growth developed by
Robert Slow and Trevor Swan in
1956.
• It has three basic sources for GDP:
i) Labor (L)
ii) Capital (K)
Iii) Knowledge (A)
5. TECHNOLOGICAL PROGRESS IN THE SOLOW MODEL
• The third source of economic growth is technological progress.
• It is called the residual factor of economic growth.
• Technological progress alters the relationship between inputs
(capital and labor) and the output of goods and services and thus
leads to exogenous increases to societies capacity to produce.
6. EFFICIENCY OF LABOR
• To incorporate technological progress, we must return to
the production function that relates total capital K and
total labor L to total output Y. Thus far, the production
function has been:
Y = F(K, L).
We now write the production function as:
Y = F(K, L × E),
where E is a new variable called the efficiency of labor.
7. • Suppose, K= 4 in both 1984 and 2011
L= 10 in 1984 and L= 1 in 2011
The old function F(K,L) will say that output is larger in 1984.
• But we know that output is the same in both years because just
one worker in 2011 can do the work of 10 workers of 1984.
• We need a new production function : F(K, L × E)
8. • Assumption: the efficiency of labor grows at the constant and
exogenous rate g.
Example : if g= 0.02, then each unit of labor force 2 percent
efficient each year : output increases as if the labor force had
increased 2 percent.
• This is called labor augmenting and ‘g’ is called the rate of labor
augmenting technological progress.
• The labor force ‘L’ is growing at rate ‘n’ and the efficiency of each
unit of labor E is growing rate ‘g’.
Effective number of workers L × E is growing at rate n+g.
