Measuring the Economy 2

The costs of unemployment include a reduction in the standard of living, emotional stress, and a loss of output for society.

Okun's law describes the relationship between real GDP and unemployment. The equation for Okun's law is:

(the percentage change in real GDP) = 3% - 2 * (change in the unemployment rate).

This equation basically says that real GDP grows at about 3% per year when unemployment is normal. For every point above normal that unemployment moves, GDP falls by 2%. Similarly, for every point below normal that unemployment moves, GDP rises by 2%.

The equation for Okun's law is (the percentage change in real GDP) = 3% - 2 * (change in the unemployment rate). Using the information given in the problem, we get 3% - 2 * (-4) = 11%.

The 3 major types of unemployment are frictional, structural, and cyclical. The 4 major reasons for unemployment are minimum wage laws, labor unions, efficiency wages, and job search.

The labor force is the sum of the employed plus the unemployed or 30 + 10 = 40 people. The unemployment rate is the ratio of the unemployed to the total labor force or (10 / 40) = 25%.
