1. Suppose that a consumer has utility function U= Ax²y²with MU_x = 2Ay²x and MU_y = 2Ax²y. Which of the following statements is false? (A) The marginal utilities are positive. (B) The marginal rate of substitution is diminishing. (C) The indifference curves are bowed away from the origin. (D) The indifference curves are downwards sloping.

2. Let the price elasticity of demand for a soft drink be – 2. In the year 2020, the per capita consumption of soft drinks was about 500 cans per person, and the average price was $1.00 per can. If we suppose that demand for the soft drink is linear, , where a and b are constants, is quantity demanded and P is price, an estimate of the demand equation could be: (A) = 100 – 2P (B) = 1500 – 2P (C) = 1500 – 1000P (D) = 1000 – 1500P

3. Suppose that we illustrate demand and supply with quantity on the horizontal axis and income on the vertical axis. Let demand be a function of price and income, (P, I). Which of the following statements is true? (A) A change in income will cause a shift in the demand curve. (B) A change in income level is represented by a movement along the demand curve. (C) Income is treated as an exogenous variable in the graphical analysis. (D) Price and income together must change in order to create a shift in the demand curve.

4. Suppose that U(x,y) = min(3x,y). Further suppose that per unit and per unit and income is I = $105. For this consumer, the optimal basket to buy would be (A)(x,y) = (9,3) (B) (x,y) = (3,1) (C)(x,y) = (1,3) (D) (x,y) = (3,9)

【已刪除】5. For this consumer, the optimal basket to buy would be (A) (x,y) = (9,3) (B) (x,y) = (3,1) (C) (x,y) = (1,3) (D) (x,y) = (3,9)

5. Suppose a consumer buys two goods, x and y , and has income of $30. Initially and the consumer chooses basket A with x =5 and y= 5. The prices change to and the consumer chooses basket B with x = 1 and y = 13. (A) These choices are not consistent with utility maximization. (B) With this information it is not possible to determine if these choices are consistent with utility maximization. (C) These choices are consistent with utility maximization. (D) Basket B must be strictly preferred to basket A .

6. Suppose the consumer’s utility function is given by U(x,y) = where

The equation for this consumer’s demand curve for x is (A) (B) (C) (D)

7. Suppose the consumer’s utility function is given by U(x,y) = xy + y where

The equation for this consumer’s demand curve for x when I ＞

8. Consider a production function of the form Q = K ² L² with marginal products and . What is the marginal rate of technical substitution of labor for capital at the point where K = 5 and L = 5? (A) 5 (B) 25 (C) 50 (D) 1

9. Consider the CES production function . This production function exhibits (A) decreasing returns to scale. (B) constant returns to scale. (C) increasing returns to scale. (D) either decreasing or constant returns to scale, but more information is needed to determine which one.

11. In Game (*) above, (A) Player A choosing A1 and Player B choosing B1 is a Nash equilibrium. (B) Player A choosing A2 and Player B choosing B1 is a Nash equilibrium. (C) Player A choosing A1 and Player B choosing B2 is a Nash equilibrium. (D) there are no Nash equilibria in pure strategies.

12. In Game (*) above, in the Nash equilibrium in mixed strategies (A) player A chooses A1 with a 2/9 probability. (B) player A chooses A1 with a 3/9 probability. (C) player A chooses A1 with a 4/9 probability. (D) player A chooses A1 with a 5/9 probability.

13. In Game (*) above, if the players move sequentially with Player B choosing first, the Nash equilibrium will be (A) Player A choosing A1 and Player B choosing B1. (B) Player A choosing A1 and Player B choosing B2. (C) Player A choosing A2 and Player B choosing B1. (D) Player A choosing A2 and Player B choosing B2.

14. Suppose a decision maker has a utility function U = √I and is faced with a lottery where there is a 30% chance of earning $30 and a 70% chance of earning $80. What is the expected utility of this lottery? (A) 7.6 (B) 7.9 (C) 8.2 (D) 8.5

15. A decision-maker is faced with a choice between a lottery with a 30% chance of a payoff of $30 and a 70% chance of a payoff of $80, and a guaranteed payoff of $65.
