Two firms, A and B, each currently dump 20 tons of chemicals into the local river. The government has decided to reduce the pollution and from now on will require a pollution permit for each ton of pollution dumped into the river. The government gives each firm 10 pollution permits, which it can either use or sell to the other firm.

After the two firms buy or sell pollution permits from each other, we would expect that

Firm B will no longer pollute. and Firm A will not reduce its pollution at all
