Suppose that changes in bank regulations expand the availability of credit cards, so

that people need to hold less cash. Use the money demand and supply diagram in the long run to answer

the following:

a.   How does this event affect the demand for money? (explain with graph + words)

b. If the Bank of Canada does not respond to this event, what will happen to the price level?

c. If the Bank of Canada wants to keep the price level stable, what should it do? (show on graph + explain with words)

1. How did employees of Enron (and employees of the utilities company in Oregon) end up losing billions in retirement funds?

Consider a representative firm with the total costs of TC=16+Q^2 (and marginal costs of 2Q, MC=2Q) . The market demand curve is given by P=36-1/2Q and the starting market price is $18

1. Graph the starting scenario using comparative statistics

2. Why is this not a long run equilibrium?

3. What happens in order to transition to the long run?

4. Graph the long run equilibrium using comparative statistics

5. How many firms are in the market in the long run?

1. What percent of its demand deposits is this bank holding in cash reserves (the reserve ratio)? (1 mark)

2. If a deposit of $10,000 is made, how much of this is lent out to maintain the same reserve ratio? How much can bank deposits in the system potentially increase as a result?  

3. Show the balance sheet after the bank receives the $10,000 deposit and then makes loans from that deposit.

1. The following two linear functions represent a market (thus one is a supply function, the other a demand function). Circle the answer closest to being correct. Approximately what will suppliers willingly supply if the government controls the market price to be $3.00 (You must first find the market equilibrium price and quantity in order to see how the $3.00 relates to them)? Q = 100 – 4.6P and Q = 75 + 6.2P
Possible answers: 2.3 84.3 86.2     89.3     93.1     93.6 (all close, but approximate)

2. There has been a change in the market (represented in 1 above). The change is represented by the following two equations. Circle the one correct conclusion that describes the market change. Q = 90 + 6.2P   and Q = 110 – 4.6P
Possible Answers: a. demand has decreased,  b. demand has increased, c. supply has decreased, d. supply has increased, e. supply has decreased and demand has decreased, f. supply has increased and demand has increased

3. Circle the function on the answer sheet that represents the marginal revenue (MR) function for this demand function: Q = 75 – 7P
Possible Answers: a. MR=19.57-.044Q, b. MR=21.74-.044Q, c. MR=26.09-.044Q, d. MR=33.33-.066Q, e. MR= 30.00-0.4Q, f. MR=10.71-0.28Q

4. Circle the quantity that maximizes total revenue (TR) for the marginal revenue (MR) function selected in number three (3).
Possible Answers: 38.25   44.48   49.41   50.50   59.30   75.00

5. If supply decreases but demand remains the same, we can conclude that the new equilibrium:
Possible Answers: a. Price must fall but market quantity is indeterminate.    b. Quantity must increase but market price is indeterminate.   c. Price must increase but market quantity is indeterminate.   d. Quantity must decrease but market price is indeterminate.   e. Price must increase and Quantity must increase.     f.   Price must increase and quantity must decrease.

You are planning to estimate a short- run production function for your firm, and you have collected the following data on labor usage (L) and output (Q):

a. Please key in the data into MS Excel for regression analysis. Estimate your firm’s
short-run production function. Do the parameter estimates have the appropriate algebraic
signs? Are they statistically significant at the 5 percent level?
b. At what point do you estimate marginal product (MP) begins to fall?
c. Calculate estimates of average products (AP) and marginal products (MP) when the
firm employs 20 workers.
d. When the firm employs 20 workers, is short-run marginal cost (MC) rising or falling?

Jack and Kate both care about the poor. A €10 reduction in poverty generates benefits of €7.50 for both Jack and Kate. Assume that Jack and Kate can make a charity donation of a maximum of €10 each if they so wish.

(i) Using a pay-off matrix outline and explain the four possible pay-offs.

(ii) Assuming both Jack and Kate have an incentive to free-ride on the giving of others how much will each of them contribute to poverty alleviation? Explain, using your pay-off matrix. (iii) (ii)Using your pay-off matrix explain how compelling both Jack and Kate to give €10 each through an income tax system could benefit both of them and lead to a Pareto improvement.
