In the market for lemons, we defined buyers' and sellers' utility functions as: UE= ZAX j+M j=1 Us= ZBX j+M i=1 where both A and B were positive, and the magnitude of A was greater than the magnitude of B. Now consider the market for health insurance. Assume that buyers' and sellers' utility functions are of the same form as above. That is, the coefficients A and B can assume new values, but the structure of the equations must remain unchanged. Based on what X represents in the market for health insurance a.) Do you expectA and B to be positive or negative in the market for health insurance? Why
