Question

1. two best friends, each of whom belongs to opposing political coalition, typically vote oppositely in local elections and so their votes “cancel each other out”. they each gain two units of utility from a vote for their positions (and lose two units of utility from a vote against their positions). however, the bother of actually voting costs each one unit of utility.

diagram a game in which they choose whether to vote or not to vote.

2. Suppose the two bestfriends from opposing political coalition have common interest to vote for a public policy on banning vaping in all public places and imposing higher sales tax for all vaping products in attempt to decrease addiction to nicotine in teenagers and young adults. The two friends agreed not to vote in tomorrow’s election to allow vaping in public places. Would such an agreement improve utility? Would such an agreement be an equilibrium?
