Assume the following production functions in a Ricardian model: Country A: X = 1/8L_X and Y = 1/2L_Y and Country B: X = 2L_X and Y = 2L_Y Also, assume that Country A's labor endowment is L = 80 and B's labor endowment is L= 40. From this information we can derive:

a. (MCx/MCy) equals 0.25Y per X in A. b. the PPF for B is given by 40 = 2X + 2Y. c. Country A has a comparative advantage in the production of X. d. the maximum amount of good Y that A can produce is 160 units. e. the derivative the X production function in A would yield a number that is in units of the number of hours it takes to produce one unit of X. f. the labor requirement coefficient for good X in B equals 2. g. if the relative price of X is in the mutually beneficial range, then (W_B/W_A) must be such

that 4 < (W_B/W_A) < 16. h. if the relative price of X is very close to 1 Y per X, but still in the mutually beneficial range, then most of the gains from trade would go to country B. i. if you think two of the above are correct, choose this option. j. if you think three of the above are correct, choose this option k. if you think all of the above are correct, choose this option. l. if you think none of the above are correct, choose this option.
