The Law of Diminishing Returns (A) applies only in the long-run. (B) describes the phenomenon of a decreasing marginal product. (C) applies when there are negative returns to scale. (D) applies if all inputs are variable. (E) describes the behavior of a production function when all inputs’ ratios are fixed.

(A) The payments to labor and capital equal the value of the output. (B) Labor receives the largest share of income. (C) Profits equal the marginal product of labor. (D) The marginal products of labor and capital are linear-homogeneous functions of labor and capital. (E) The law of variable proportions does not hold.
Suppose that the production function of Firm A for the production of X is Q=L0.75K0.25, where Q is the rate of output of X, L is the rate of labor input, and K is the rate of input of capital services. If L is increased by 8 per cent and K is increased by 4 per cent, Q will increase by (A) 4% (B) 5% (C) 6% (D) 7% (E) 8%
A production analyst reports that the marginal product of a production worker in a firm exceeds that of a clerk. If markets for both types of workers are competitive and if the firm is minimizing the cost of producing its particular level of output, it can be concluded that (A) the firm should employ more production workers (B) production workers are more educated (C) clerks are less essential to the operations of the business (D) clerks are paid more than production workers (E) clerks are paid less than production workers
As the wage rate increases due to a decrease in labor supply, (A) the value of the marginal product will fall. (B) the value of the marginal product will rise. (C) a shortage of labor will result. (D) a surplus of labor will result. (E) none of the above. The graph above shows the marginal revenue product curve and supply curve of labor for a firm. The introduction of new management techniques dramatically increases worker productivity. Which of the following changes is most likely to occur? (A) The supply curve will shift to the left, increasing the wage rate. (B) The supply curve will shift to the right, increasing employment. (C) The marginal revenue product curve will shift to the right, increasing the wage rate. (D) The marginal revenue product curve will shift to the left, reducing employment. (E) Neither the marginal revenue product curve nor the supply curve will shift, but the wage will increase and employment will fall.
Assume that the government imposes a minimum wage in labor markets where the equilibrium wage had been below the new minimum. Which of the following will be expected effect on employment and total wage payments? Employment Total Wage Payments
(A) Decrease Increase (B) Decrease Decrease (C) Decrease Might either increase or decrease (D) Increase Increase (E) Increase Might either increase or decrease
A technological improvement which makes workers more productive at collecting apples will cause: (A) A fall in wages of apple picking workers which would lead to a reduction (shift inside) in labour supply; (B) An increase in supply of apple picking workers and thus an increase in their employment; (C) An increase in the marginal revenue product of apple picking workers, and thus an increase in their wage; (D) A decline in demand for workers as machines replace manual labour, and, therefore, a fall in the number of apple picking workers hired; (E) A fall in the marginal revenue product of apple picking workers, and thus an fall in their wage.

Which of the following statements can explain inequality in the distribution of income? I.
