Consider the following simple principal/agent problem. A firm hires an employee to perform a sales function. Let e denote employee's effort level. Suppose e is not observable by the prin- cipal. Assume that every additional unit of effort increases sales by $300, and the employee's marginal cost of effort satisfies the following equation: 0 mc(e) = {e - 2 15 if e 15 if e 15 The employee's salary is determined as: $3000 base salary plus 15 percent commission on sales. Under this salary scheme, the employee will choose the effort level e at and the firm's profit would be $
