It is not 1.6. I have tried that. It is either A, B, or D.
Two identically able agents are competing for a promotion. The promotion is awarded on the basis of output (whomever has the highest output, gets the promotion). Because there are only two workers competing for one prize, the losing prize=0 and the winning prize =P. The output for each agent is equal to his or her effort level times a productivity parameter (d). (i.e. Q2=dE1 , Q2=dE2). If the distribution of “relative luck” is uniform, the probability of winning the promotion for agent 1 will be a function of his effort (E1) and the effort level of Agent 2 (E2). The formula is given by...Prob(win)=0.5 + α(E1-E2), where α is a parameter that reflects uncertainty and errors in measurement. High measurement errors are associated with small values of α (think about this: if there are high measurement errors, then the level of an agent’s effort will have a smaller effect on his/her chances of winning). Using this information, please answer the following questions. Both workers have a…

- A major proposed industry in the future is the provision of global satellite wifi. However, the actual willingness to pay for such a service is unknown. Assume there's a 40% chance that there are 1 billion people willing to pay $100/year for a service that would cost $60/year to provide and a 60% chance that those people would be willing to pay $10/year for a service that would cost $60/year to provide.

Assume that you could spend $75 billion to launch a testbed of the program, that could then either be scrapped if the willingness to pay were $10 or continue at normal cost afterward (for simplicity, assume that the program will last forever and generate constant annual returns if it is continued) if the willingness to pay were $100.

- An amount of money is accumulating; in period t (= 1, 2, . . . , T) its size is $2t. In each period two people simultaneously decide whether to claim the money. If only one person does so, she gets all the money; if both people do so, they split the money equally; and if neither person does so, both people have the opportunity to do so in the next period. If neither person claims the money in period T, each person obtains $T. Each person cares only about the amount of money she obtains. Formulate this situation as an extensive game with perfect information and simultaneous moves, and find its subgame perfect equilibria).

This could produce a substantial pay-off in terms of increased revenue net of costs but will require an investment of 1.4 million pesos.

A smaller scale project to re-decorate her premises. At 500,000 pesos this is less costly but will produce a lower pay-off. Research data suggests a 30% chance of a gain of one million pesos but a 70% chance of being only 500,000 pesos. Continuing the present operation without change. It will cost nothing but neither will it produce any pay-off. Clients will be unhappy and it will become harder to rent the flats out when they become free. What is the best alternative?
