CHAPTER 3

1)You and two partners start a company. However, your partners play no role in running the company. You devote all our time and talent to run your own business rather than working for someone else. You incur an(a):

1. 1. explicit cost.
   2. marginal cost.
   3. sunk cost
   4. opportunity cost.

2. A business owner makes 1000 items a day. Each day he/she contributes 8 hours to produce those items. If hired, elsewhere he/she could have earned $250 an hour. The item sells for $15 each. Production does not stop during weekends. If the explicit costs total $150,000 for 30 days, the firm’s accounting profit for the month equals:

a) $300,000

b) $60,000

c)   $450,000

d)   $240,000

Production does not stop during weekends. If the explicit costs total $150,000 for 30 days, the economic profit for the month equals:

b) $60,000

c)   $450,000

4. The opportunity cost of an action:

   2. is equal to explicit cost
   3. is equal to the next best alternative forgone
   4. is the total cost of an action

5. Economists argue that:
   1. accounting costs consider all types of costs including implicit costs
   2. there is an opportunity cost associated with all decisions.
   3. economic decisions do not have opportunity costs but other decisions do.
   4. economic decisions should consider sunk costs

8. Variable costs are
   1. costs that vary with output
   2. equal marginal costs
   3. not considered in decision-making

9. Economic Value Added helps firms to avoid the hidden-cost fallacy
   1. by ignoring the opportunity costs to using a capital

   3. by taking all capital costs into account including the cost of equity
   4. none of the above

10. A manager invests $400,000 in a technology to reduce overall costs of production. The company managed to reduce their cost per unit from $2 to $1.85. After a year, the manager has an opportunity to outsource production to another company at a cost per unity of $1.75. If you are the manager, you
    1. should consider the $400,000 as sunk cost and therefore it should not be relevant to the decision.
    2. should base your decision upon economic profit and not accounting profit
    3. should avoid the fixed-cost fallacy
    4. all the above

11. Which of the following statements is true?
    1. Economic profits ignore implicit costs and revenues.
