(4)is set at a price below the equilibrium price. (A). (2) only (B). (4) only (C). (1) and (3) only (D). (2) and (4) only 2. A binding price floor (1) causes a surplus. (2) caeses a shortage. (3) is set at a price above the equilibrium price. (4)is set at a price below the equilibrium price. (A). (1) only (B). (3) only (C). (1) and (3) only (D). (2) and (4) only 3. When the minimum wage is set above the equilibrium market wage, (A).there will be an excess demand for labor at the minimum wage. (B).it will have no effect on the quantity of labor employed. (C).the unemployment rate will rise. (D).the qualrice of the labor force will rise. (E).the unemployment rate will fall. 4. The particular price that results in quantity supplied being equal to quantity demanded is the best price because it (A). maximizes costs of the seller. (B). maximizes tax revenue for the government. (C). maximizes the combined welfare of buyers and sellers. (D). minimizes the expenditure of buyers. 5. Consumer surplus (A). is the amount of a good that a consumer can buy at a price below equilibrium price. (B). is the amount a consumer is willing to pay minus the amount the consumer actually pays. (C). is the number of consumers who are excluded from a market because of scarcity. (D). measures how much a seller values a good. 6. Total surplus in a market will increase when the government (A). imposes a binding price floor or a binding price ceiling on that market. (B). imposes a tax on that market. (C). Both a and b are correct. (D). Neither a nor b is correct. 7. Refer to Figure 1. What is the consumer's marginal rate of substitution? (A). 12 (B). 4 (C). 1 (D). We do not have enough information to answer the question because the MRS varies along the graph. 8. Refer to Figure 1. What is the consumer's marginal rate of substitution as she moves A to B ? (A). 12 (B). 6 (C). 4 (D). 1 9. Refer to Figure 2. Suppose that a consumer is originally at point R. Then the price of good X decreases. Which of the following represents the income effect of the price decrease? (A). the movement from point R to point S. (B). the movement from point R to point T. (C). the movement from point T to point S. (D). None of the above is correct. 10.Refer to Figure 2. Suppose that a consumer is originally at point R. Then the price of good X decreases. Which of the following represents the substitution effect of the price decrease? (A). the movement from point R to point S. (B). the movement from point R to point T. (C). the movement from point T to point S. (D). None of the above is correct. 二、計算題（請寫出計算過程，否則不予計分） 1.
