Learning Objectives Explain and illustrate graphically the concept of the aggregate production function Explain how its shape relates to the concept of diminishing marginal In this article, we review the debate and conclude that the elasticity of labor supply of the aggregate household is much higher than the elasticity of the Aggregate Labor Supply Federal Reserve Bank of Minneapolis
Our model of longrun aggregate supply tells us that in the long run, real GDP, the natural level of employment, and the real wage are determined by the economy's production the aggregate labor supply is given by H = ph¯ The aggregate labor supply elasticity is infinite, as the standin agent’s utility is linear inp While the aggregate labor supply is On the Aggregate Labor Supply Richmond Fed
The demand and supply curves for labor intersect at the real wage at which the economy achieves its natural level of employment We see in Panel (a) of Figure 86 “Deriving the LongRun Aggregate Supply Curve” that the equilibrium real wage is ω 1 and the natural level of employment is L1 Panel (b) shows that with employment of L1, theAggregate supply, also known as total output, is the total supply of goods and services produced within an economy at a given overall price level in a given time period It is represented by theAggregate Supply Explained: What It Is, How It Works
One important reason for the decline in labor force participation is that working families do not have the supports they need to both engage in employment and ensure quality care for children andThe more leisure people demand, the less labor they supply Two aspects of the demand for leisure play a key role in understanding the supply of labor First, leisure is a normal good All other things unchanged, an increase in income will increase the demand for leisure Second, the opportunity cost or “price” of leisure is the wage an122 The Supply of Labor Principles of Economics
LongRun Aggregate Supply The longrun aggregate supply (LRAS) curve relates the level of output produced by firms to the price level in the long run In Panel (b) of Figure 225 “Natural Employment and LongRun Aggregate Supply”, the longrun aggregate supply curve is a vertical line at the economy’s potential level of outputThere is a single real Figure 225 Natural Employment and LongRun Aggregate Supply When the economy achieves its natural level of employment, as shown in Panel (a) at the intersection of the demand and supply curves for labor, it achieves its potential output, as shown in Panel (b) by the vertical longrun aggregate supply curve LRAS at Y P72: Aggregate Demand and Aggregate Supply: The Long Run
Shortrun aggregate supply (SRAS) is a concept that represents the totality of the goods and services supplied in an economy at a particular price This macroeconomic concept helps determine the state of the economy and is affected by different factors called determinants, such as labor productivity, prices, government rules, subsidies, and taxesMaybe we can draw some graph about priceoutput (quantity) similar to supply curve in microeconomics! This curve derived from production function and labor market condition, it characterizes the supply side of macroeconomy, we call it aggregate supply curve (AS) The higher the real output ( \ (Y^ {r}\) ), the lower the unemployment Lecture 11: Aggregate Supply Pages
The longrun aggregate supply curve is vertical because in the long run, achanges in the price level affect potential GDP via other variables, such as the size of the labor force, capital stock, and technology b changes in the price level do not affect potential GDP, as potential GDP depends on the size of the labor force, capital stock, and technologyAnother event that can shift the longrun aggregate supply curve is an increase in the supply of labor, as shown in Figure 239 An increased supply of labor could result from immigration, an increase in the population, or increased participation in the labor force by the adult population62: Growth and the LongRun Aggregate Supply Curve
Aggregate supply is the goods and services produced by an economy It's driven by the four factors of production: labor, capital goods, natural resources, and entrepreneurship These factors are The aggregate demand/aggregate supply, or AD/AS, model is one of the fundamental tools in economics because it provides an overall framework for bringing these factors together in one diagram In addition, the AD/AS framework is flexible enough to accommodate both the Keynes’ law approach—focusing on aggregate demand and the How the AD/AS model incorporates growth, unemployment,
Formulae Aggregate supply = Y = Ynatural + a (P Pexpected) In this formula Y is output, Ynatural is the natural rate of output that exists when all productive factors are used at their normal rates, a is a constant greater than zero, P is the price level, and Pexpected is the expected price level Aggregate demand = Y = C (Y T) + I (r) + GLabor force Projections of the future supply of labor are calculated by applying BLS labor force participation rate projections to population projections produced by the US Census Bureau When the aggregate economic projection is final, the components of GDP are supplied to the commodity component of the projections processCalculation : Handbook of Methods: US Bureau of Labor Statistics
Over time as expectations adjust, the shortrun aggregate supply curve will shift to the right moving the economy back to the natural rate of output Figure 6 3 a When the United States experiences a wave of immigration, the labor force increases, so longrun aggregate supply increases as there are more people who can produce output bthe aggregate labor supply is given by H = ph¯ The aggregate labor supply elasticity is infinite, as the standin agent’s utility is linear inp While the aggregate labor supply is infinitely elastic in this environment, the underlying assumptions—homogeneity and complete market—are vulnerable even to casual empiricismOn the Aggregate Labor Supply Richmond Fed
Policies that discourage immigration or encourage emigration reduce an economy’s longrun aggregate supply Improving education increases a labor force’s productivity Policies that encourage labor participation increase the workforce, thereby increasing the longrun aggregate supply Entrepreneurs Governments that provide a hospitableIncreased labor supply Because more labor is available, the economy can produce more when each is employed And changes in the labor supply are affected by population growth, labor force participation rates, and net immigration More qualified workforce If human capital improves, laborers will be more productiveLongRun Aggregate Supply: Its Curve And Influencing Factors
In this article, we review the debate and conclude that the elasticity of labor supply of the aggregate household is much higher than the elasticity of the identical households being aggregated The aggregate household utility function differs from the individuals’ utility functions for the same reason that the aggregate production functionFactors Some factors influence the LRAS curve Labour supply Labour supply depends on population growth, level of immigration, and the number of people participating in the labor forceAn increase in labor will leads to a rise in output Thus, there are longrun aggregate supply curve shifts towards the right sideLongRun Aggregate Supply (LRAS) Definition, Formula, Curve
