3. Voluntary contributions toward a public goodLarry and Raphael are considering contributing toward the creation of a public park. Each can choose whether to contribute $400 to the public park or to keep that $400 for a new suit.Since a public park is a public good, both Larry and Raphael will benefit from any contributions made by the other person. Specifically, every dollar that either one of them contributes will bring each of them $0.80 of benefit. For example, if both Larry and Raphael choose to contribute, then a total of $800 would be contributed to the public park. So, Larry and Raphael would each receive $640 of benefit from the public park, and their combined benefit would be $1,280. This is shown in the upper left cell of the first table.Since a new suit is a private good, if Larry chooses to spend $400 on a new suit, Larry would get $400 of benefit from the new suit and Raphael wouldn't receive any benefit from Larry's choice. If Larry still spends $400 on a new suit and…
3. Voluntary contributions toward a public good
Eleanor and Kyoko are considering contributing toward the creation of a public park. Each can choose whether to contribute $400 to the public park or
to keep that $400 for a cell phone.
Since a public park is a public good, both Eleanor and Kyoko will benefit from any contributions made by the other person. Specifically, every dollar
that either one of them contributes will bring each of them $0.80 of benefit. For example, if both Eleanor and Kyoko choose to contribute, then a total
of $800 would be contributed to the public park. So, Eleanor and Kyoko would each receive $640 of benefit from the public park, and their combined
benefit would be $1,280. This is shown in the upper left cell of the first table.

3. Suppose the production possibility frontier for an economy that produces one public
good (y) and one private good (x) is given by
x*+100y =5,000
This economy is populated by 100 identical individuals, each with a utility function of
the form
Utility = (x,y)2
where x,is the individual's share of private good production (=x/100). Notice that the public
good is nonexclusive and that everyone benefits equally from its level of production.
a. If the market for x and y were perfectly competitive, what levels of those goods
would be produced? What would the typical individual's utility be in this situation?
b. What are the optimal production levels for x and y? What would the typical
individual's utility level be? (Hint: The numbers in this problem do not come out
evenly, and some approximations should suffice.)

Suppose that Capsule Corporation and Red Ribbon Company are producers of spaceships. In their production processes, each firm emits 50 units of pollution. Now, the government wants to reduce smoke emissions by 40% by issuing tradable permits.
