This means that the price of good Y will rise and/or the price of good X must fall. Process continues until all excess demand and supply are eliminated, and IC tangent to each other (on the Contract curve) and to the price line (which will now be flatter. So in the competitive equilibrium all markets clear, MRSA = MRSB = PX/PY. (see lecture overheads) 5. Suppose the production possibilities for two countries, A and B, producing two goods, X and Y, are as follows: | A | B | X | 2 | 7 | Y | 4 | 7 | They can each produce any linear combination as well. Measuring X on the horizontal axis, the joint production possibility frontier: a) will kink away from the origin at 7 units of X. b) will kink toward the origin at 7 units of X. c) will kink away from the origin at 2 units of X d) will kink toward the origin at 2 units of X e) will not have a kink answer: a jointly the countries can produce either a total of 9X or 11Y. MRT of A is – 4/ 2= -2 MRT of B is - 7/7 = -1 Country B has comparative advantage
