Consider a potential, voluntary exchange between two people. Assume that both people have complete information about each other's preferences and that there are no transaction costs. Consumers A and B have between them 9 units of X and 15 units of Y. Initially, A has 6 of X and 10 of Y, and B has 3 of X and 5 of Y. Consumer A's marginal rate of substitution of X for Y is 2 and B's marginal rate of substitution of X for Y is 1/3. Is there room for a mutually beneficial, voluntary exchange? Determine which consumer would trade for more X and which consumer would trade for more Y. If trade takes place, can you explain the terms of trade?
