Problem
1. Why does the payroll tax have the same impact on wages and employment regardless of whether it is imposed on workers or on firms?
2. Do immigrants reduce the wages of native workers? Do immigrants "take jobs away" from native workers?
3. Describe the trends in wages and employment implied by the cobweb model for the engineering market. What would happen to the cobwebs if an economics consulting firm sold information on the history of wages and employment in the engineering market?
