2. A rm is going to hire a new manager. Assume that there is a wide set of homogeneous managers with Bernoulli utility function u=w"'5-g(e), where W represents the wage rate, e the manager's effort, and g(e) the cost of effort. The effort level can either be high or low. The cost ofa high effort level is 10, and the cost ofa low effort level is 1. Assume that the managers\" reservation utility is zero. The prot level depends on the effort level chosen by the manager. The following table represents the probabilities of each profit level ( before paying the manager's wage) Prot 10'D 2m} 5013 mm mau we mw- 2.1 What is the optimal contract when effort is observable?| 2.2 What is the optimal contract when effort is not observable (assume that the wage rate can never be negative) 2.3 Calculate the range of values for the high effort level, such that the rm chooses to implement that effort level (assume that the wage rate can never be negative)
