(a) Calculate the set of Pareto optimal allocations (a convincing figure is enough).
(b) Assume that the planner wants to implement some Pareto efficient allocation
(x¹, x²) ((x1, x²), (x², x²)) where x½ ‡ 0, as an equilibrium with
transfers. Prove that any price vector such that 0 < p1 < 2√√x½ can
support that allocation (normalizing p2
=
: 1).
(c) What happens if the planner wants to implement precisely the allocation
((1,0), (0, 1))?
