Given the following information for a monopolistic competitor:

Demand: P = 78 – 5(Q)

Marginal revenue: MR = 78 – 10(Q)

Marginal cost: MC = 2(Q) + 10

Average total cost at equilibrium is 14

2. At what price (P) will this firm maximize profit? _______

3. What is the total revenue (TR) earned at this output level? _____

4. What is the total cost (TC) accrued at this output? _____

5. What profit or loss is experienced by this firm? ______

6. Could this firm be in a longrun situation? (answer 1 = yes, 2 = no) _____

Why does the auto industry prefer uniform (national) standards for automobile emissions as opposed to regionally varying standards? Are uniform standards beneficial to everyone?

Explain how the shape of the load duration curve for a particular system affects the selection of technology mix

Consider two neighboring island countries called Arcadia and Dolorium. They each have 4 million labor hours available per week that they can use to produce jeans, rye, or a combination of both. The following table shows the amount of jeans or rye that can be produced using 1 hour of labor.

Initially, suppose Arcadia uses 1 million hours of labor per week to produce jeans and 3 million hours per week to produce rye, while Dolorium uses 3 million hours of labor per week to produce jeans and 1 million hours per week to produce rye. Consequently, Arcadia produces 6 million pairs of jeans and 36 million bushels of rye, and Dolorium produces 12 million pairs of jeans and 16 million bushels of rye. Assume there are no other countries willing to trade goods, so, in the absence of trade between these two countries, each country consumes the amount of jeans and rye it produces.

Arcadia's opportunity cost of producing 1 pair of jeans is of rye, and Dolorium's opportunity cost of producing 1 pair of jeans is of rye. Therefore, has a comparative advantage in the production of jeans, and has a comparative advantage in the production of rye.

Suppose that each country completely specializes in the production of the good in which it has a comparative advantage, producing only that good. In this case, the country that produces jeans will producemillion pairs per week, and the country that produces rye will producemillion bushels per week.

In the following table, enter each country's production decision on the third row of the table (marked “Production”).

Suppose the country that produces jeans trades 14 million pairs of jeans to the other country in exchange for 42 million bushels of rye.

In the following table, select the amount of each good that each country exports and imports in the boxes across the row marked “Trade Action,” and enter each country's final consumption of each good on the line marked “Consumption.”

When the two countries did not specialize, the total production of jeans was 18 million pairs per week, and the total production of rye was 52 million bushels per week. Because of specialization, the total production of jeans has increased bymillion pairs per week, and the total production of rye has increased bymillion bushels per week.

Because the two countries produce more jeans and more rye under specialization, each country is able to gain from trade.

Calculate the gains from trade—that is, the amount by which each country has increased its consumption of each good relative to the first row of the table. In the following table, enter this difference in the boxes across the last row (marked “Increase in Consumption”).

Consider a consumer’s consumption-saving decision in a two-period model. Suppose that the real interest rate is r. This consumer’s current income is y and the future income is y’ . The government imposes lumpsum taxes t and t’ in the current period and future period, respectively. In addition, the government subsidizes savings with rate q: the consumer needs to pay 1 /(1+q) to save one unit of consumption. That is, the budget constraint of the current period is c + s/( 1 + q) = y − t.

(a) (10 points) Derive the lifetime budget constraint. Graphically illustrate this person’s budget constraint, endowment point, and optimal choice. Assume that this consumer is the lender (saver).

(b) (10 points) What will be the effects of decreasing q on (c, c’ , s), respectively? Assume that this consumer remains as the lender, and the substitution effects are dominating. Explain.

Show by graphing how a change (upward shift or downward shift) in each of the following factors would alter the shape of the total product curve for medical care. A. An increase of education spending. B. An improvement in lifestyle. C. An improvement in the environment.

What are the basic differences between proprietary and public companies?

Given that labor is a resource that needs to be used efficiently, what responsibility do you feel the government has in decreasing unemployment? Does the negative relationship between inflation and unemployment have any impact on your decision?

3. Please illustrate in one market:
a. a $0.15 excise tax
b. a $0.15 sales tax (independently, not a sales and excise tax)
c. Does the legal incidence of the tax affect the economic incidence?

You decide to open a retirement account at your local bank that pays 8%/year/month (8% per year compounded monthly). For the next 20 years, you will deposit $500 per month into the account, with all deposits and withdrawals occurring at month’s end. On the day of the last deposit, you will retire. Your expenses during the first year of retirement will be covered by your company’s retirement plan. As such, your first withdrawal from your retirement account will occur on the day exactly 12 months after the last deposit.

What monthly withdrawal can you make if you want the account to last 15 years

What monthly withdrawal can you make if you want the account to last forever (with infinite withdrawals)?
