Consider an exchange economy with two consumers A and B, and teo goods X and Y. A's utility function is Ua=X^(1/3)Y^(2/3) and B's utility function is Ub=X^(2/3)Y^(1/3). Initial endowments for A are (18,4) and for B are (2,6). Q. Suppose that B realizes he has market power and hence optimizes by controlling price. Individual A behaves as price taker. Formulate the optimization problem of individual B and solve the equilibrium.

A consumer’s preferences are represented by the following utility function: u(x, y) = lnx + 1/2 lny 1. Recall that for any two bundles A and B the following equivalence then holds A ≽ B ⇔ u(A) ≥ u (B) Which of the two bundles (xA,yA) = (1,9) or (xB,yB) = (9,1) does the consumer prefer? Take as given for now that this utility function represents a consumer with convex preferences. Also remember that preferences ≽ are convex when for...
