Signaling when education is productive. there are two groups of workers: h types (higher productivity) and l types (lower productivity). let ch(e) denote a type h worker’s cost function for obtaining education and let cl(e) denote the cost function for a type l worker, where: cl(e) = 0.5 · e 2 (10) ch(e) = 0.25 · e 2 . (11) mh = 4e is the marginal product of labor for a type h worker and ml = 2e is the marginal product for a type l worker. by assumption, the marginal product of labor for each type depends on the amount of education received. a fraction p = 0.4 are type h and the rest of the workers are type l. as usual, the utility that a worker receives from working is the wage minus cost: u(e) = w(e) − c(e) (12) answer the following:
(a) clearly define a pooling equilibrium for this problem.
(b) solve for all values of ¯e that are consistent with a pooling equilibrium. show your work.
(c) clearly define a separating equilibrium for this problem.
(d) solve for all values of ¯e that are consistent with a separating equilibrium. show your work.

You manage an equity fund with an expected risk premium of 10% and a standard deviation of 14%. the rate on treasury bills is 6%. your client chooses to invest $60,000 of her portfolio in your equity fund and $40,000 in a t-bill money market fund. what is the expected return and standard deviation of return on your client’s portfolio?

Areal estate agent is considering changing her cell phone plan. there are three plans to choose from, all of which involve a monthly service charge of $20. plan a has a cost of $.42 a minute for daytime calls and $.17 a minute for evening calls. plan b has a charge of $.52 a minute for daytime calls and $.15 a minute for evening calls. plan c has a flat rate of $80 with 275 minutes of calls allowed per month and a charge of $.38 per minute beyond that, day or evening.a. determine the total charge under each plan for this case: 150 minutes of day calls and 70 minutes of evening calls in a month. (do not round intermediate calculations. round your answer to 2 decimal places. omit the "$" sign in your response.)c. if the agent will use the service for daytime calls, over what range of call minutes will each plan be optimal? (round each answer to the nearest whole number.include the indifference point itself in each answer.)d. suppose that the agent expects both daytime and evening calls. at what point (i.e., percentage of total call minutes used for daytime calls) would she be indifferent between plans a and b?
