Firm’s Demand for Labor LO: 10-1 Labor is the most important of the resources used by firms. Labor demand is a derived demand, thus it depends on the productivity of labor the price of the good or service it helps produce Derived demand is the demand for a resource that results from the demand for the product it helps produce 10-2
3
Marginal Revenue Product and Marginal Revenue Cost LO: 10-1 Marginal revenue product (MRP) of labor is the change in a firm’s total revenue when it employs one more unit of labor. Marginal resource cost (MRC) of labor is the change in a firm’s total cost when it employs one more unit of labor. In a competitive labor market, MRC is equal to market wage rate. MRP = Change in total revenue Unit change in labor MRC = Change in total cost Unit change in labor 10-3
4
MRP of Labor as Labor Demand Schedule LO: 10-1 MRP=MRC can be written as MRP=wage rate. The MRP schedule therefore constitutes the firm’s demand for labor because each point on this schedule (or curve) indicates the quantity of labor units the firm would hire at each possible wage rate. The market demand for labor is the horizontal summation of all the individual firm demand curves for labor. 10-4
5
Changes in Labor Demand The labor demand curve can shift if there are: Changes in product demand: higher product demand – higher labor demand. Changes in productivity: higher productivity of labor – higher labor demand. Productivity depends on Quantity of other resources Technological advance Quality of labor Changes in the prices of other resources: a decline in price of complementary resources increases labor demand a change in price of substitute resources has an ambiguous effect on labor demand LO: 10-2 10-5
6
Elasticity of Labor Demand Elasticity of Labor Demand (E w ) is a measure of the responsiveness of employers to a change in the wage rate. Also called wage elasticity of demand. E w < 1: labor demand is inelastic E w > 1: labor demand is elastic E w = 1: labor demand is unit-elastic E w = Percentage change in labor quantity Percentage change in the wage rate LO: 10-3 10-6
7
Changes in Elasticity of Labor Demand Wage elasticity of demand depends on: Ease of resource substitutability: the greater the substitutability, the more elastic is the labor demand Elasticity of product demand: the greater the elasticity of product demand, the greater the elasticity of labor demand Ratio of labor cost to total cost: the greater the share of labor in total cost, the greater the elasticity of labor demand LO: 10-3 10-7
8
Market Supply of Labor The supply curve for each type of labor slopes upward, indicating that firms must pay a higher wage rate in order to attract workers away from the alternative job opportunities available to them and workers not in the labor force. The intersection of labor supply and labor demand determine the equilibrium wage rate and level of employment in a given labor market. LO: 10-4 10-8
9
Competitive Labor Market Many employers compete for specific types of labor. Many workers with identical skills supply that type of labor. Individual employers are “wage takers.” Individual firm’s labor supply is perfectly elastic at the market wage rate. Firms use MRP=MRC rule to determine employment at market wage. LO: 10-4 10-9

Monopsony In labor market monopsony, the single employer is a “wage maker.” Monopsonist’s labor supply curve is the same as market labor supply curve and is upward-sloping. The MRC curve lies above the labor supply curve and MRC exceeds the wage rate. Monopsonist will use MRP=MRC rule to determine how much labor to hire and pay wage corresponding to this quantity supplied. LO: 10-4 Monopsony is a market structure in which there is only a single buyer of a good, service, or resource. 10-11

Union Models In some labor markets, workers sell their labor services collectively through labor unions. Unions work to raise wage rates for members. LO: 10-5 Exclusive (craft) unions Restrict supply of skilled labor to increase the wage rate received by union members Inclusive (industrial) unions Include as members all workers in an industry Put great pressure on firms to agree to wage demands through the threat of a strike 10-13

Wage Differentials Wage differentials are the differences between the wages of different groups of workers. Wage differentials can arise either on the demand or the supply side of labor markets. A weak labor demand will result in a low equilibrium wage, but a strong labor demand will result in a high equilibrium wage. A low labor supply will result in a high equilibrium wage, while a higher labor supply results in a low equilibrium wage. Members of noncompeting groups differ in their mental and physical abilities and in their levels of education and training, and therefore, they receive different compensation. LO: 10-6 10-16
