6. Consider a two-consumer economy in which wa = (1,0), w" = (0, 1) and u"(x1, x?) = min {r{ , x} } for J = A, B. (a) Derive a competitive equilibrium for this economy in which pi/p; = 1. (b) Illustrate the equilibrium from (a) in an Edgeworth box. (c) Derive a competitive equilibrium for this economy in which pi/p; = 1/3. (d) Illustrate the equilibrium from (c) in an Edgeworth box. (c) What other prices can be supported as part of some competitive equilibrium
