Derived Demand
The demand for factors of production is derived from the demand for the end products.
For example, if computer software is in high demand, then demand for computer programmers will be high.

Definitions
Marginal product of labor (MPL): output of the last worker
Value of marginal product of labor (VMPL): value of output of the last worker
VMPL = P x MPL

• Technological Change
• Supply of Other factors

![Page 17: Workers, Wages and Unemployment in the Modern Economy Chapter 8.](https://reader035.fdocuments.us/reader035/viewer/2022062421/56649d405503460f94a1a8fd/html5/thumbnails/17.jpg)
Unemployment
• Labor Unions– Benefits
• Reduced worker exploitation• Support progressive labor legislation• Increase productivity• Promote democracy in the workplace
![Page 18: Workers, Wages and Unemployment in the Modern Economy Chapter 8.](https://reader035.fdocuments.us/reader035/viewer/2022062421/56649d405503460f94a1a8fd/html5/thumbnails/18.jpg)
Unemployment
• Labor Unions– Costs
• Unions cause otherwise competitive labor markets to function inefficiently.
• Unions may prevent companies from competing in the global economy.
![Page 19: Workers, Wages and Unemployment in the Modern Economy Chapter 8.](https://reader035.fdocuments.us/reader035/viewer/2022062421/56649d405503460f94a1a8fd/html5/thumbnails/19.jpg)
Unemployment
• Unemployment Insurance:– Helps to reduce the costs of unemployment.– May give the unemployed an incentive to
search longer and less intensely.– Unemployment benefits must balance the
benefit of providing support to the worker with the cost of reducing the incentive to work.
![Page 20: Workers, Wages and Unemployment in the Modern Economy Chapter 8.](https://reader035.fdocuments.us/reader035/viewer/2022062421/56649d405503460f94a1a8fd/html5/thumbnails/20.jpg)
Unemployment
• Other Government Regulations– Health and Safety Regulations
• These regulations can reduce the demand for labor by:
– Increasing employer costs.– Reducing productivity.
• The reduction in demand will:– Increase unemployment.– Lower wages.
