The above table has the marginal product schedule for a firm. If the firm is a perfect competitor and the price of the product is constant at $2 a unit, complete the table. If the wage rate is $8 an hour, how many workers does the firm hire?

Consider two firms that are in the same industry and the industry is competitive. Initially each firm employees equal amounts of type A and type B labor

Labor is perfectly mobile between the two firms, and type A and type B labor are perfect substitutes. Diagram separately the equilibrium conditions in the labor markets for type A and type B labor. What must be true about the wages both firms face? Why? Now assume that one of the firms decides not to hire type A labor due to some type of discrimination. What do you think will happen to the type A labor supply for both firms? How do you think the action will affect the wages for type A labor relative to type B? Why?

Based on the figure below. Starting from long-run equilibrium at point C, an increase in government spending that increases aggregate demand from AD to AD1 will lead to a short-run equilibrium at point ________ creating _____gap.  

A. D; an expansionary B. B; no output C. B; expansionary D. A; a recessionary
