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.

Why is it downward sloping? Because of the law of diminishing marginal
returns
12
Each additional resource is less productive and therefore is worth less than the previous one

MRP increases causing demand to shift right

3 Shifters of Resource Demand1.) 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? 15

increased significantly?1.Price of the good would

________ in the demand for processor assemblers.2. Increase in the price for plastic piping causes the
demand for copper piping to _________.3. Increase in demand for small homes (compared to big
homes) leads to a(n) _________ the demand for lumber.4. For shipping companies, __________ in price of trains
leads to decrease in demand for trucks.5. Decrease in price of sugar leads to a(n) __________ in
the demand for aluminum for soda producers.6. Substantial increase in education and training leads to

Resource Supply ShiftersSupply Shifters for Labor1. Number of qualified workers
• Education, training, & abilities required2. Government regulation/licensing
Ex: What if waiters had to obtain a license to serve food?
3. Personal values regarding leisure time and societal roles.Ex: Why did the US Labor supply increase during
WWII?Why do some occupations get paid more
than others?

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 (Market Power)•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!).

From our Textbook
• Compensating differentials
• Differences in talent
• Differences in the quality of human capital
• Idea of “efficiency wage”
• Marginal productivity theory of income distribution
27
![Page 28: Unit 5: The Resource Market](https://reader035.vdocuments.us/reader035/viewer/2022062322/568149de550346895db70434/html5/thumbnails/28.jpg)
Marginal Productivity Theory of Income Distribution
• Idea that wages are in equilibrium based on the marginal resource cost of the “last” worker hired
• Wages are in equilibrium when MRPL = MRCL
• But there are problems with this argument
28
![Page 29: Unit 5: The Resource Market](https://reader035.vdocuments.us/reader035/viewer/2022062322/568149de550346895db70434/html5/thumbnails/29.jpg)
Problems with the Marginal Productivity Theory of Income Distribution
• There are income gaps between groups of people who really should be paid the same– Do the wage differences really reflect
differences in marginal productivity?
• Theory gives a moral justification for the distribution of income. What percentage of our national income does the top 1% control?
