Suppose that the St Clair river, which flows along the border between Ontario and Michigan, becomes polluted and needs to be cleaned.

Question
Suppose that the St Clair river, which flows along the border between Ontario and Michigan,
becomes polluted and needs to be cleaned. The American and Canadian governments need to
make a decision on whether to clean the river or not. They must make this decision
simultaneously. If both countries invest in cleaning the river, they each get a payoff of 871. If one
country invests in cleaning the river, but the other one doesn't, the country that spends the
money on the cleanup gets a payoff of 161, while the other country gets to enjoy the benefits of
the clean river without having to spend any money, and therefore gets a payoff of 1159. If neither
country invests in cleaning the river, they must both deal with the consequences of the pollution,
and they each get a payoff of -639.
Suppose that the U.S. and Canada are again making decisions simultaneously. Find the Nash
