Some of the trickier aspects of designing the right contract with your agent include properly aligning her incentives and monitoring her work. Supervising your agent can be especially hard when she knows more than you do about the area of work. For example, hiring an agent who’s a lawyer and paying her on an hourly basis may induce her to spend more time than you think you necessary – at your expense. She might become a literary perfectionist, spending hours crafting and polishing an offer letter to the other side when, as far as you’re concerned, the second draft would have done just fine. To prevent her from running up needless hours, you might opt instead for a fixed-fee engagement. Then, however, she may cut corners, doing just enough to reach her fee.
