A new highway is to be constructed with two alternative designs. Design A calls for a concrete pavement costing $90 per foot with a 20-year life; two paved ditches costing $3 per foot each; and three box culverts every mile, each costing $9,000 and having a 20-year life. Annual maintenance will cost $1,800 per mile; the culverts must be cleaned every five years at a cost of $450 each per mile. Design B calls for a bituminous pavement costing $45 per foot with a 10-year life, two sodded ditches costing $1.50 per foot each; and three pipe culverts every mile, each costing $2,250 and having a 10-year life. The replacement culverts will cost $2,400 each. Annual maintenance will cost $2,700 per mile; the culverts must be cleaned yearly at a cost of $225 each per mile; and the annual ditch maintenance will cost $1.50 per foot per ditch. Compare the two designs using equivalent worth per mile for a 20-year period. Find the most economical design if the MARR is 6% per year.

1) Apple was effectively a monopolist in the tablet computer market in the spring of 2010. You could go for the iPad or, well, the iPad. It didn’t even come in a choice of colors. Suppose the marginal cost of producing iPads is constant at $200, and the inverse demand curve for iPads is P = 1,000 – 5Q (where Q in millions and P in dollars). The associated marginal revenue is MR = 1,000 – 10Q.

1. How much should Apple charge, and how many will it sell at that price?
2. Compute the consumer surplus and Apple’s producer surplus. (It is helpful if you draw the demand and MC curves first. Recall that CS is the area under demand curve and above the price. PS is the area below the price and above the MC).
3. Now let’s think about how market would look like if Apple behaved like a competitive firm and priced at marginal cost. How many iPads will Apple? Compute the new consumer surplus and Apple’s producer surplus.
4. Compute the value of the “deadweight loss” from monopolization? (Note: One method, use the producer and consumer surpluses you found in parts (b) and (c). Another method, compute the DWL directly by finding the area of the triangle).
5. Draw your results you found in parts (a) – (d) in one P-Q space.
6. Suppose a government regulatory agency sets a price ceiling of $400 per iPad. How many iPads will Apple sell, and what will be its producer surplus?
7. Compute and compare the degrees of monopoly power (Lerner Index) for cases in (a), (c), and (f).
8. Suppose, instead of price ceiling, government imposes a per unit tax of $200. Find the Apple’s price, quantity and producer surplus for iPad.

You have extra $5,000 to invest. You do not need the money now but will need it after 3 years, so you plan to cash your investment at the end of 3 year. Usually your investments earn 7% annual interest compounded annually and you’d like to consider it as your minimum acceptable rate of return. You are considering several investment opportunities: Option 1. Depositing your money on the high interest savings account that earns 0.58% interest each month. Option 2. Buying and holding a stock that grows 10% per year. Option 3. Making a personal loan of $5000 to a friend and receiving $400 per year. Select the best option and explain why.

2. The main factors influencing technological change.

Question 1

(a) Interpret the prediction of Hecksher-Ohlin theorem on international trade in the exports and imports.

(b) Determine three (3) critical assumptions of a simplistic and specific version of Hecksher-Ohlin theory for gains in trade, which can be challenged as not true in the real world?
