Question
8. Consider a two-good, two-consumer exchange economy, with utility functions and endowments (15) U1(x1, x2) = x 1 1/2 x 2 1/2 , e 1
8. Consider a two-good, two-consumer exchange economy, with utility functions and endowments (15)
U1(x1, x2) = x1 1/2 x21/2 , e1 = (2, 1).
U2(x1, x2) = min { x1 , x2 } , e2 = (1, 2).
(a) Find the set of Pareto effcient allocations.
(b) Find the core of the economy.
(c) Find the aggregate excess demand functions
for goods 1 and 2.
(d) Find a Walrasian equilibrium for this economy and the associated WEA.
(e) Consider the allocation
(x11 x12) = (2/3, 4/3), (x21 ,x22) = (7/3,5/3).
i. Is this allocation feasible?
ii. Is the allocation Pareto optimal?
iii. Can this allocation be the Walrasian equilibrium allocation of a redistribution of
the endowment?
