less capital due to the substitution effect. more labor due to the substitution effect. less output due to the scale effect more capital due to the scale effect. more labor due to the scale effect.

12. Why is the short-run labor demand curve less elastic relative to the long-run labor demand curve?

A. Because firms care about changes in wages in the short-run but not in the long-run B. Because firms are better able to substitute capital for labor in the long run compared to the short run. C. Because labor is a normal good. D. Because a perfectly competitive firm can always pay lower wages in the long run E. Because isocost curves get shallower when the wage increases 13. The elasticity of substitutions is

A. the change in capital over the change in the price of labor. B. the percentage change in capital over the percentage change in labor C. the change in the price of capital over the change in the price of labor D. the percentage change in the price of capital over the percentage change in the price of labor E. the percentage change in the capital/labor ratio resulting from a 1 percent change in the relative price of labor. 14. At a wage of $25 per hour, the firm employs 50,000 hours of labor per week. If the wage would increase to $27 per hour, the firm would employ 45,000 hours of labor per week. What is the elasticity of labor demand?

A. -2.50. B. -1.50. C. -1.25. D. -0.50. E. -0.25.

The more two factors are substitutes in the firm’s production function, the greater is the elasticity of substitution. E. Perfect substitutes do not need to be employed in a 1-to-1 ratio by the firm

A. the greater is the supply elasticity of capital B. the greater is the elasticity of substitution between labor and capital C. the greater is the elasticity of demand for the firm's output. D. the greater is labor's share in total costs E. All of the above. 18. Labor demand is more elastic the greater the elasticity of substitution between labor and capital because

A. workers supply more labor when their wage increases. B. the firm's output price falls when the firm produces more output. C. a firm is less willing to pay higher labor costs if it is easy for the firm to substitute capital for labor. D. firms always have the option of substituting capital for labor E. a firm's technology is slow to change. 19. The cross-elasticity of labor with respect to capital is

A. the change B. the change C. the percent D. the percent E. the percent

in labor relative to a change in capital. in wages relative to a change in the price of capital change in labor relative to a percent change in capital change in wages relative to a percent change in the price of capital change in labor relative to a percent change in the price of capital

20. If unskilled labor and capital are substitutes,

A. demand for unskilled labor increases when the price of capital decreases B. the cross-elasticity between unskilled labor and capital is positive C. the price of unskilled labor decreases when the price of capital increases D. the price of capital is increasing. E. the demand curve for capital is upward-sloping. 21. The imposition of a minimum wage on a competitive labor market will likely

A. create additional employment opportunities because some low-skilled workers will now see their wage increase. B. lower the wages of workers earning more than the minimum wage. C. create unemployment as some people enter the labor market while some firms reduce the quantity of labor they are willing to employ due to the increased wage. D. increase unemployment of high-skilled workers as firms substitute high-skilled labor for lowskilled labor. E. lower the unemployment rate of low-income families.
