Unit 6: The FACTOR MARKET (aka: The Resource Market … or Input Market)
Unit 6: The Factor Market • Length: 5-6 Lessons • Chapters: 12 & 13 in textbook • Good News: • Only two Graphs to learn (PC vs. Monopsony – for factor market) • Many concepts are just the application of things we have already learned. • Basically just Supply and Demand
Product Market Producers Supply Households Demand
Resource Market Producers Demand Households Supply
Resource Markets Perfect Competition Monopsony Perfectly Competitive Labor Market • Characteristics: • Many small firms are hiring workers • No one firm is large enough to manipulate the market. • Many workers with identical skills • Wage is constant • Workers are wage takers • Firms can hire as many workers as they want at a wage set by the industry 5

DERIVED DEMAND Example 1: If there was a significant increase in the demand for pizza, how would this affect the demand for cheese? Cows? Milking Machines? Veterinarians? Vet Schools? Etc. Example 2: An increase in the demand for cars increases the demand for… Derived Demand- The demand for resources is determined (derived) by the products they help produce. 7
How do you know how many resources (workers) to employ? Continue to hire until… MRP = MFC Remember the Paper Chain Activity
Change in Total Cost Marginal Factor Cost = Change in Inputs Marginal Factor Cost (MFC) The additional cost of an additional worker (or resource). In a perfectly competitive labor market the MFC equals the WAGE set by the market and is constant. Ex: The MFC of an unskilled worker is $8.75. Another way to calculate MFC is:
Change in Total Revenue Marginal Revenue Product = Change in Inputs Marginal Revenue Product (MRP) The additional revenue generated by an additional worker (resource). In perfectly competitive product markets the MRP equals the marginal product of the resource times the price of the product. Ex: If the Marginal Product of the 3rd worker is 5 and the price of the good is constant at $20 the MRP is……. $100 Another way to calculate MRP is:

DEMAND RE-DEFINED • What is Demand for Labor? • Demand = quantities of workers that businesses are willing and able to hire at each wage. • What is the Law of Demand for Labor? • There is an INVERSE relationship between wage and quantity of labor demanded. • What is Supply for Labor? • Supply = quantities of individuals that are willing and able to sell their labor at each wage. • What is the Law of Supply for Labor? • There is a DIRECT (or positive) relationship between wage and quantity of labor supplied. • Workers face trade-off between work and leisure 19

Who demands labor? • FIRMS demand labor. • Demand for labor shows the quantities of workers that firms will hire at different wage rates. • Market Demand for Labor is the sum of each firm’s MRP. • As wage falls, Qd increases. • As wage increases, Qd falls. Wage DL Quantity of Workers 21
Who supplies labor? • Individuals supply labor. • Supply of labor is the number of workers that are willing to work at different wage rates. • Higher wages give workers incentive to leave other industries or give up leisure activities. Labor Supply Wage • As wage increases, Qs increases. • As wage decreases, Qs decreases. Quantity of Workers 22
Market Equilibrium Wage (the price of labor) is set by the market. EX: Supply and Demand for Carpenters Labor Supply = MFC Wage $30hr Labor Demand = MRP Quantity of Workers 23
Individual Firms Wage SL= MFC DL= MRP Qe Q 24
Example: • You hire workers to mow lawns. The wage for each worker is set at $100 a day. • Each lawn mowed earns your firm $50. • If you hire one worker, he can mow 4 lawns per day. • If you hire two workers, they can mow 5 lawns per day together. • What is the MFC for each worker? • What is the first worker’s MRP? • What is the second worker’s MRP? • How many workers will you hire? • How much are you willing to pay the first worker? • How much will you actually pay the first worker? • What must happen to the wage in the market for you to hire the second worker? 25
You’re the Boss • You own a business. • Assume the you are selling the goods in a perfectly competitive PRODUCT market so the price is constant at $10. • Assume that you are hiring workers in a perfectly competitive FACTOR market so the wage is constant at $20. • Also assume the wage is the ONLY cost. • Given the table (next slide) To maximize profit how many workers should you hire? 26

P.Q. • Give an example of Derived Demand. • Define MRP. • Explain the difference between MRP and MR. • Why does the MRP fall as more workers are hired? • Identify the two ways to calculate MRP. • Define MFC. • Explain the difference between MFC and MC. • How does a firm decide how many workers to hire?
Does having an education guarantee you a higher income?
Why do people with only high school degrees make less money on average? Employers assume they have low productivity and will generate less additional revenue. 36

Adjusting for Inflation • Wage – The price of labor defined as currency per unit of labor worked. • NOMINAL Wage – The price of labor not adjusted for inflation. • REAL wage – The price of labor adjusted for inflation; Economists use the CPI to adjust numbers from prices/wages from different times into a consistent unit of measure (ie. “2010 dollars”)
Wage Trends Other US labor market trends: • Workers with higher skills are paid more than unskilled workers. This gap is increasing. • College graduates earn more than high school graduates and the gap has been increasing. • Women, on average, are paid lower than men, although the gap has become more narrow over the years.

3 Shifters of Factor Demand • 1.) Derived Demand: • Changes in the Demand for the Product • Price increase of the product increases MRP and demand for the resource. • 2.) Changes in Productivity • Technological Advances increase Marginal Product and therefore MRP… Demand. • 3.) Changes in Price of Other Resources • Substitute Resources • Ex: What happens to the demand for assembly line workers if price of robots falls? • Complementary Resources • Ex: What happens to the demand nails if the price of lumber increases significantly?
