There are three people who consume public and private goods. As usual, the public good is x, and i represents person i's consumption of the private good. The prices of both the public good and the rivate good are $1 per unit. The initial endowments of the private good are (w1, w2, w3) = (10, 10, 10).

(i) Assume that the public good is purchased privately, and that person 3 is the first to go to the market and buy the public good.

There are three people who consume public and private goods. As usual, the public good is x, and
i represents person i's consumption of the private good. The prices of both the public good and the
rivate good are $1 per unit. The initial endowments of the private good are (w1, w2, w3) = (10, 10, 10).
'he three people have the following utility functions:
%3D
u1 (x, y1) = In x + Y1,
u2 (x, y2)
= 2 In a + Y2,
u3(r, Y3)
= 3 In r + Y3.
(i) Assume that the public good is purchased privately, and that person 3 is the first to go to the
market and buy the public good. Assume he does not act strategically he ignores persons 1
and 2 when he buys x, and thinks only of his own utility maximisation problem. What is the
outcome? How much of the public good does person 3 buy? How much do persons 1 and 2 buy?
