Suppose the real interest rate is 0%. Daniel worked for 60 years and he retired for 20
years. When Daniel had a job, his annual income was $10,000. During retirement,
the annual pension he received was $6,000. Suppose Daniel smoothed consumption
completely. What was the amount of savings Daniel had when he retired?
O $16,000
O $120,000
$600,000

4. Suppose that you are an airline executive and you come to work one morning to find a memorandum on our desk indicating that the Boeing 747 that your company leased to fly between New York and London is bringing in revenues of $200,000 per day. You also know that the direct operating expenses (wages for the flight crew, aviation fuel, and that awful airline food) are $180,000 per day. Lastly, suppose you calculate that the interest cost of the loan to pay for the airplane was $40,000 per day. Should you continue to fly the plane? Why might your answer depend on the decision time frame, and what additional information would you need?

- Suppose that when the interest rate on loans is 16 percent, businesses find it unprofitable to invest in machinery and equipment. However, when the interest rate is 14 percent, $5 billion worth of investment is profitable. At 12 percent interest, a total of $10 billion of investment is profitable. Similarly, total investment increases by $5 billion for each successive 2-percentagepoint decline in the interest rate. Describe the relevant relationship between the interest rate and investment in a table, on a graph, and as an equation. Put the interest rate on the vertical axis and investment on the horizontal axis. In your equation use the form i = a + bI, where i is the interest rate, a is the vertical intercept, b is the slope of the line (which is negative),and I is the level of investment.arrow_forward10arrow_forward1.
