2. 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 2

5. 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 Perfect Competition Monopsony Resource Markets

7. 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

8. Continue to hire until… MRP = MFC How do you know how many resources (workers) to employ? 8 Remember the Paper Chain Activity

9. Push-Up Machine 9

10. I am the inventor of a new generator that converts human push ups into safe and clean electrical energy. Each push up generative $1 worth of energy. Supply and demand in the labor market has resulted in a equilibrium wage of $10 (MRC = $10). The supply curve for the firm is perfectly elastic at $10…how much will you work for? Assuming identical skills, hire the first worker (do push ups in a 4ft x 7ft box). Let’s start hiring workers (Each worker must make sound effects) 10 The Push-Up Machine

11. 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: Marginal Factor Cost = Change in Total Cost Change in Inputs 11 Marginal Factor Cost (MFC)

12. 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 3 rd worker is 5 and the price of the good is constant at $20 the MRP is……. $100 Another way to calculate MRP is: Marginal Revenue Product = Change in Total Revenue Change in Inputs 12 Marginal Revenue Product (MRP)

13. Calculate MP and MRP The Push-Up Machine Quantity Labor Total ProductMarginal Product MRP @ $1 Price

14. Supply Supply and demand in the INDUSTRY GRAPH has resulted in a equilibrium wage of $10. How much MUST each worker work for? Why not ask for more? Why not less? Demand If each push up generates $1 worth of energy what is the MRP for each worker? How much is each worker worth to the firm? The Push-Up Machine

15. Why does the MRP eventually fall? Diminishing Marginal Returns. Fixed resources means each worker will eventually add less than the previous workers. The MRP determines the demand for labor The firm is willing and able to pay each worker up to the amount they generate. Each worker is worth the amount of money they generate for the firm. The Push-Up Machine

21. 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. DL Quantity of Workers Wage As wage falls, Qd increases. As wage increases, Qd falls. 21

22. 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. Quantity of Workers Wage As wage increases, Qs increases. As wage decreases, Qs decreases. Labor Supply 22

23. Market Equilibrium Wage (the price of labor) is set by the market. EX: Supply and Demand for Carpenters Quantity of Workers Wage Labor Supply = MFC Labor Demand = MRP $30hr 23

25. 25 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. 1.What is the MFC for each worker? 2.What is the first worker’s MRP? 3.What is the second worker’s MRP? 4.How many workers will you hire? 5.How much are you willing to pay the first worker? 6.How much will you actually pay the first worker? 7.What must happen to the wage in the market for you to hire the second worker?

26. 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.

39. 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”)

40. Average Wage (1964-2006)

41. Wage Trends Other US labor market trends: 1)Workers with higher skills are paid more than unskilled workers. This gap is increasing. 2)College graduates earn more than high school graduates and the gap has been increasing. 3)Women, on average, are paid lower than men, although the gap has become more narrow over the years.

49. 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? 49

60. What are other reasons for differences in wage? Labor Market Imperfections- Insufficient/misleading job information- This prevents workers from seeking better employment. Geographical Immobility- Many people are reluctant or too poor to move so they accept a lower wage Unions- Collective bargaining and threats to strike often lead to higher than equilibrium wages Wage Discrimination- Some people get paid differently for doing the same job based on race or gender (Very illegal!).

90. Labor Unions Goal is to increasing wages and benefits

91. How can Unions Increase Wages? 1.Convince Consumers to buy only Union Products Ex: Advertising the quality of union/domestic products 2.Lobbying government officials to increase demand Ex: Teacher’s Unions petition governor to increase spending. 3.Increase the price of substitute resources Ex: Unions support increases in minimum wage so employers are less likely to seek non-union workers

95. Why is Globalization Happening? Globalization is the result of firms seeking lowest costs. Firms are seeking greater profits. Parts are made in China because labor in significantly cheaper. What is Outsourcing? Outsourcing is when firms send jobs overseas. What types of jobs are outsourced? For many years it was only unskilled jobs, but now other skilled jobs are sent overseas.

97. Outsourcing- Advantages and Disadvantages Disadvantages Increases U.S. unemployment Less US tax revenue generated from workers and corporations means less public benefits Foreign workers don’t receive same protections as US workers Advantages Lowers prices for nearly all goods and services Decreases world unemployment Improves quality of life and decreases poverty in less developed countries
