In this article, I examine the operation of ordinary linear contingent
fees in a model of litigation in which the recovery on a claim is a f
unction of the lawyer's efforts, My object here is to analyze the line
ar fee that maximizes the client's welfare in the presence of attorney
moral hazard. I identify the optimal fee as the one that minimizes tw
o agency costs: underinvestment in the claim, and attorney rents. I al
so attempt to identify how the optimal linear fee varies with differen
t case characteristics.
