Roger has invited Caleb to his party. Roger must choose whether or not to hire a clown. Simultaneously, Caleb must decide whether or not to go to the party. Caleb likes Roger but he hates clowns - he even hates other people seeing clowns! Caleb’s payoff from going to the party is 4 if there is no clown, but 0 if there is a clown there. Caleb’s payoff from not going to the party is 3 if there is no clown at the party, but 1 if there is a clown at the party. Roger likes clowns - he especially likes Caleb’s reaction to them but does not like paying for them. Roger’s payoff, if Caleb comes to the party, is 4 if there is no clown, but 8 − x if there is a clown (x is the cost of a clown). Roger’s payoff, if Caleb does not come to the party, is 2 if there is no clown, but 3 − x if there is a clown there.
