Suppose Ann is working on a project with John. Both must decide whether to put into a descent amount of effeort into the project. Since Ann is the leader of the project, her contribution determines whether the project will be successful. If she puts into a descent amount of effort, the project will be finished on time and each will enjoy 3 units of benefit. If she decides not do so, the project will not be finished on time, neither one will get benefit, Suppose a decent amount of effort incurs a cost of 1 unit for each person. Please draw normal form represent the situation and identify the Nash Equilibrium if there is any. Would both be happy about the outcome and why? Please explain in detail.

Answer:

It is a problem on game theory. Two persons are involved in the game. They are Ann and John. Among them Ann is leader. So the return will depend upon the action taken by Ann. John has no option but to follow what Ann is doing. If she puts into a decent effort the project will be finished in time. In that situation both of them will get benefit of 3 units. If she decides to put a decent amount of effort then each of them will incur a cost of 1 unit. Thus net benefit from decent effort is 3-1=2 units. Finally if no decent effort is made, then project will remain incomplete. None of them will gain anything.

Nash equilibrium is a situation where optimum benefit will accrue. Ann as a leader will optimize her pay off y putting decent effort. John being the follower will adopt the strategy of leader. It will give return of 2 units to both of them. It is equilibrium. It implies that players will not deviate from it as no extra gain will be available from such deviation.

Result: Nash equilibrium is put decent effort to gain 3 units each.

Investment and Work Effort: Suppose that Lisa must decide whether or not to invest $40,000 in a new computer system for her company. If she buys the system, she must also hire a technician, Bart. The effect on the firm’s revenues depends on Bart’s effort. If Bart puts in high effort (H) in working with the new system, then revenues increase by $120,000. If Bart puts in low effort (L) then revenues increase by only $50,000. Bart has disutility of...

John and Jane are working on a project, and all of their project meetings are scheduled to start at 9:00. John always arrives promptly at 9:00. Jane is highly disorganized and arrives at a time that is uniformly distributed between 8:20 and 10:50. The time (measured in minutes, a real number that can take fractional values) between 8:20 and the time Jane arrives is thus a continuous, uniformly distributed random variable. If Jane arrives before 9:00, their project meeting will...

Suppose we are asked to decide whether a new project should be launched. We expect that cash flows over the five-year life of the project will be $350 million in the first two years, $375 million in the next two years, and $385 million in the last year. The initial investment is expected to cost $995 million.   The firm’s required return is 10%. Using a financial calculator, compute the NPV and IRR of this project.

You are trying to decide whether to accept or reject a project. The project will generate a cash flow of $15,000 in year one; $25,000 in year two; $20,000 in year three; and $4,000 in year four. The project costs $40,000 initially. The firm has a weighted average cost of capital of 8%. Your firm generally accepts projects that payback in three years or less. What is the discounted payback of the project? Should you accept or reject the project?
