- You need to hire some new employees to staff your startup venture. You know that potential employees are distributed throughout the population as follows, but you can't distinguish among them: Employee Value $30,000 $49,000 $68,000 $87,000 Probability 0.25 0.25 0.25 0.25 The expected value of hiring one employee is $ Suppose you set the salary of the position equal to the expected value of an employee. Assume that employees will not work for a salary below their employee value. The expected value of an employee who would apply for the position, at this salary, is $ Given this adverse selection, your most reasonable salary offer (that ensures you do not lose money) isarrow_forwardDiscuss: i) diversifiable risk; ii) market risk; iii) systematic risk iv) unsystematic risk;arrow_forwardThe value of a successful project is $420,000; the probabilities of success are 1/2 with good supervision and 1/4 without. The manager is risk neutral, not risk averse as in the text, so his expected utility equals his expected income minus his disutility of effort. He can get other jobs paying $90,000, and his disutility for exerting the extra effort for good supervision on your project is $100,000. (a) Show that inducing high effort would require the firm to offer a compensation scheme with a negative base salary; that is, if the project fails, the manager pays the firm an amount stipulated in the scheme. (b) How might a negative base salary be implemented in reality? (c) Show that if a negative base salary is not feasible, then the firm does better to settle for the low-pay, low-effort situation.arrow_forward
- Consider the model of competitive insurance discussed in lectures (Topic 6.7). Peter is a risk averse individual with the utility function u(w) = w0.5. His current wealth is $300 and with probability 1/2 he will incur a loss of D = $240, but with probability 1/2 he will incur no loss. Ann has the same utility u(w) = w0.5 and current wealth $300 as Peter, but a different probability of loss: she will incur a loss of D = $240 with probability 0.1, and no loss with probability 0.9. As we showed in lectures, in the separating equilibrium Peter is offered actuarially fair full insurance contract, so his wealth is equal to $180, whether loss happens or not. Ann will be offered an insurance contract with the amount of insurance (approximately) equal to Group of answer choices 0 16 36 66 120 240arrow_forwardSetup from Question 1) An expected utility maximiser owns a car worth £60 000 and has a bank account with £20 000. The money in the bank is safe, but there is a 50% probability that the car will be stolen. The utility of wealth for the agent is u(y) = In(y) and they have no other assets. Question 2)arrow_forwardConsider a coin toss experiment and the following assets. Asset A gives £200 if the first is heads, £50 for tails. Asset B gives £200 if the second is heads and £50 for tails. Asset C is half of A plus half of B. Assets A and B are independent. Show that the expected value of each asset is the same and C reduces risk. Explain why C reduces risk?arrow_forward
