hy does a measure of labor productivity—the output produced per worker– rise for many firms during recessions? During the boom years period of 2005through November 2007, the annual average output per worker was lower in U.S.manufacturing than during the Great Recession of 2007–2009 as well during therelatively low-demand years since then through 2013.Firms produce less output during recessions as demand for their products falls.Consequently, firms typically lay off workers during recessions. Thus, whetheroutput per worker rises or falls depends on whether output or employment fallsby more. The labor productivity pattern over the business cycle differs across in-dustries. If we know about a firm’s production process, can we predict whetheroutput produced per worker will rise or fall with each additional layoff?
Consider an economy with production function given by Y = AK0:5L0:5 where A is the total factorproductivity (TFP), K is the capital stock and L is the labor input. For simplicity assume capital is xed and equal to 1. Assume A=100.a. Write the rm's problem of choosing labor demand. Derive the demand for labor as a functionof the real wage.b. Assume labor supply is inelastic and xed at L= 100. Find the equilibrium values of the wageand the employment level for this economy. Display graphically the labor supply and the labordemand curves. Carefully label your graph.c. Suppose the economy faces a positive productivity shock and TFP is now A=200. Displaygraphically the new labor demand function.

Let a firm's production function Q (L)=12L^2-1/20L^3 (i.e. output as TL orthe amount of production depends on the workforce, L, as Q is the number of people with a single production input). This functionlet be the foreground 0 ≤ L ≤ 200 for. Accordingly,A) What is the number of labour force (L*) that will make output (Q) the highest?B) what is the number of workers (L**) who will make the maximum amount of output per employee(i.e. Q (L)/L)?c) in both cases the output of the L* and L** values you find and the output per employee at the mosthow can you be sure it's high?

A production function has two inputs: domestic labor (Edom) and foreign labor (Efor.) The market is originally in equilibrium as shown below, and the production budget is fixed. Suppose a shock occurs that increases the marginal product of domestic labor. Assuming no changes in domestic or foreign wages, what will happen to the quantities of domestic and foreign labor employed? Initial long run equilibrium (prior to shock):
Suppose a firm’s hourly marginal product of labour is given by MPN = 0.2(200 − N), where N is the number of labour hours used in production. The amount of labour supplied by workers, NS, is given by NS = 100 + 5w, where w is the real wage. (a) Suppose the current real wage is equal to 20. How much labour will the firm want to hire? How much labour will the workers want to supply? Is there excess supply or excess demand of labour in the economy? Do you expect the real wage to go up or go down in this case? (b) Find the equation of the labour demand and calculate the equilibrium levels of real wage and full-employment. (c) If the government decides to tax the labour income, the equation of labour supply becomes NS = 100 + 5(1 − τ )w. Suppose τ = 40%. Repeat part (b). Compared to the results in (b), do the equilibrium levels of real wage and full-employment increase or decrease? Provide an intuitive explanation to your answers.
In the context of a perfectly competitive model of the labour market, an increase in technologythat raises the marginal product of labour at any given level of employment would be expected, inequilibrium, toa) reduce the amount of labour required to produce a given amount of output and hence increaseunemployment.b) shift the labour demand curve outwards and lead to an increase in employment and wages.c) have no effect upon labour supply or labour demand curves and hence have no impact onemployment or wages.d) reduce the supply of labour to the market and result in an increase in wages but a fall inemployment Why the correct answer is B?
