Assume that two individuals, A and B, are willing to trade products X and Y. Before a possible trade, A has the following marginal rates of substitution of X for Y (or of Y for X): MRSXYA = 0.80 (or equivalently, MRSYXA = 1.25). Also, before a possible trade, B has these marginal rates of substitution of X for Y (or of Y for X): MRSXYB = 1.50 (or equivalently, MRSYXB = 0.67). Determine if trade can take place that would benefit either or both. If trade can benefit either or both, determine who will trade for what.
