3. According to the Okun’s Law, when the unemployment rate increases by 1 percentage point the GDP falls by approximately 2 percentage points. But our intuition suggests that it should be rather 1-to-1 relationship, i.e., when the unemployment rate increases by 1 percentage point the GDP should fall by approximately 1 percentage point:
For instance, you have 100 workers who sew jeans, each makes 10 pairs of pants per day; then your total production is 1,000 pairs of pants per day. If you lost one worker (a 1% decrease), the remaining 99 would together make 990 pairs of pants per day (a 1% decrease).
Explain why the decline in output (GDP) may not be proportional to reduction in the number of workers employed (increase in unemployment).
