Question
A supplier and a buyer, who are both risk neutral, play the following game.
1. the buyer orders a good of quality q>=0 from the supplier and promises to pay s>=0.
2. The supplier decides which quality q'>=0 to deliver.
3. The buyer observes q' and decides how much to pay (s'>=0) for the delivered quality
The buyer's payoff is q'-s', and the supplier's payoff is s'-C(q'), where C() is a strictly convex function with C(0)=C'(0)=0. These payoffs are commonly known.
What is the subgame perfect equilibrium of this game?
Explanation / Answer
A perfect equilibrium will be when the q=q' and thus s=s'.
