Throughout this problem set, we will look at exchange economies with two goods
and two agents. Let X = R², let u denote agent i's utility, and let wie X denote
agent i's endowment.
1. Suppose u¹(x¹) = min{ri, 2} and wi = (4,8) for both agents i.
(a) Argue that every Pareto optimal allocation has r≥r for both agents
i.
(b) Argue that every allocation z with r≥r for both agents i is Pareto
optimal.
(c) Draw an Edgeworth box, with a picture depicting every Pareto-optimal
allocation. In this picture, also draw the endowment allocation, and draw
each agent's indifference curve through the endowment.
(d) Argue that, in any competitive equilibrium, the price of good 2 must be
zero.
(e) Find all competitive equilibria.
