Discuss the existence, stability and uniqueness of equilibrium in case exchange (consumption without production). Suppose and endowed with the total supply of X and total supply of Y. UA = XA XA, UB equilibrium relative price (20) Q.No.4. of pure consumers of type A consumers of type B with the = XB XB. In a competitor market what is an of X? Is this equilibrium (i) unique (ii) stable?
