5. Suppose that, at an old allocation, (35) is violated, in particular: u11(x1)/u21(x1)>f12(z2)/f11(z1). From the viewpoint of the social planner, design a reallocation that Pareto
5. Suppose that, at an old allocation, (35) is violated, in particular: u11(x1)/u21(x1)>f12(z2)/f11(z1). From the viewpoint of the social planner, design a reallocation that Pareto improves the old allocation. 3.5 Efficiency Definition 5 (An Allocation) An allocation a=({xi}iI,{yk,zk}kK) is a vector describing how all consumers and producers behave. In particular, {xi}iI and {yk,zk}kK are called consumption allocation and production allocation, respectively. Definition 6 (A Feasible Allocation) An allocation a is feasible if demand equals supply for all goods and inputs at the allocation. Definition 7 (A Pareto Improvement) An allocation a Pareto improves another allocation a if: ui(xi)ui(xi)i,ui(xi)>ui(xi)i. Definition 8 (A Pareto Efficient Allocation) A feasible allocation a is Pareto efficient if there exists no other feasible allocation that Pareto improves the allocation. characterizing a Pareto efficient allocation (from the viewpoint of the central planner): amaxs.t.given::u1=u1(x1),ui(xi)uii=1,:fk(zk)=iIxki,k=1,,n,:iIzhi=k=1nzhk,h=1,,m,{ui}i=1.
