With the use of an example, briefly explain the main difference between the ex-ante and the ex-post opportunity cost of capital. Why does this matter for the evaluation of an investment decision? In what ways can managers utilise the distinction between ex-ante and ex-post opportunity cost of capital when deciding on the firm’s strategy?
"The four factors of production are needed in an efficient market to provide goods and services at an affordable price at the right time, place and mix,"... "Missing the calibration of these factors can be disastrous for the supplier and consumer." The supplier may face higher costs of production, forcing them to charge a higher price to the consumer or risk going out of business.

Suppose that in your first year of college you spend $33,600.00 more than you earn. In your second year, your expenses increase a bit, leading you to spend $34,300.00 more than you earn. This gap goes to $35,030.00 in your third year of college, then falls a bit to $35,030.00 in your fourth and final year. What is your deficit in your third year of college? $ $ How much debt do you have that year? $ $ Will give you thumbs up only for the correct answer.

(a) If the interest rate between time periods is 50%, what is the budget constraint between consumption in the present and consumption in the future? (B) If the interest rate at which the consumer can borrow is 75% but the rate at which she can lend is25%, what is the budget constraint? (C) Suppose the interest rate is 50%. If the consumer has to pay a fee of 10% of the loan amount in order to borrow money, what is the budget constraint?arrow_forward

Mathematically, it must always be true that: Consumption = =arrow_forwardThe diagram depicts Marco's choice of consumptions in periods 1 and 2. He has $100 worth of grain in period 1 and no income in period 2. Marco has two choices. In scheme 1, he can sell the grain that he does not consume and lend the money at 10%. In scheme 2, he can invest the grain that he does not consume (e.g. planting as seed) for a return of 50%. Which of the following statements is correct? Consumption later, $ 150 110 60 39 0 0 FF(lend at 10%) FF (invest at 50%) B 60 68 Consumption now, $ 100 Going from scheme 1 to scheme 2, the substitution and income effects have opposite effects on period 2 consumption. Marco can do better than consumption choice B by investing all of his grain and borrowing against his period 2 output. O Marco is less impatient at B than at A. Marco can do better than consumption choice B by investing all of his grain and consuming the output in period 2.arrow_forwardProblem 2.

The maximum amount that group 1 is willing to pay for room and board is GHC 2500 and for entertainment is GHC 500. For group 2, the maximumamount they are willing to pay for room and board is GHC 1800 and forentertainment is GHC 750. Although Ben is not able to identify members of either group, it does know that each group values the components of the package differently. Assuming there are an equal number of members in each group and that the total membership in each group is a single individual. If the marginal cost of providing the service (room and board and/or entertainment) to each group is GHC 1000. i.
