3. Consider an economy with L=2 goods and M=2 consumers. Consumers i=1,2 have utility functions u1(x11,x12)=lnx11+(1)lnx12u2(x21,x22)=lnx21+(1)lnx22 (a) Solve for the Walrasian demand functions of each consumer, assuming agent i=1,2 has an endowment of goods i0. (b) Let 1=(1,0) and 2=(0,1). Solve for an equilibrium of this economy..
