ECO 550 Week 11 Final Exam [Chapter 9 – Chapter 17]

1. Evidence from empirical studies of long-run cost-output relationships lends support to the:
a. existence of a non-linear cubic total cost functionb. hypothesis that marginal costs first decrease, then gradually increase over the normal operating range of the firmc. hypothesis that total costs increase quadratically over the ranges of output examinedd. hypothesis that total costs increase linearly over some considerable range of output examinede. none of the above
2. The short-run cost function is:
a. where all inputs to the production process are variableb. relevant to decisions in which one or more inputs to the production process are fixedc. not relevant to optimal pricing and production output decisionsd. crucial in making optimal investment decisions in new production facilitiese. none of the above
3. Theoretically, in a long-run cost function:
a. all inputs are fixedb. all inputs are considered variablec. some inputs are always fixedd. capital and labor are always combined in fixed proportionse. b and d
4. Break-even analysis usually assumes all of the following except:
a. in the short run, there is no distinction between variable and fixed costs. b. revenue and cost curves are straight-lines throughout the analysis.c. there appears to be perfect competition since the price is considered to remain the same re-gardless of quantity.d. the straight-line cost curve implies that marginal cost is constant.e. both c and d
5. What is another term meaning the degree of operating leverage?
a. The measure of the importance of fixed cost.b. The operating profit elasticity.c. The measure of business risk.d. .e. All of the above.
6. In a study of banking by asset size over time, we can find which asset sizes are tending to become more prominent. The size that is becoming more predominant is presumed to be least cost. This is called:
a. regression to the mean analysis.b. breakeven analysis.c. survivorship analysis.d. engineering cost analysis.e. a Willie Sutton analysis.
7. George Webb Restaurant collects on the average $5 per customer at its breakfast & lunch diner. Its variable cost per customer averages $3, and its annual fixed cost is $40,000. If George Webb wants to make a profit of $20,000 per year at the diner, it will have to serve__________ customers per year.
a. 10,000 customersb. 20,000 customersc. 30,000 customersd. 40,000 customerse. 50,000 customers
8. Which of the following is not a limitation of the survivor technique for measuring the optimum size of firms within an industry?
a. since the technique does not employ actual cost data in the analysis, there is no way to assess the magnitude of the cost differentials between firms of varying size and efficiency.b. the managerial and entrepreneurial aspects of the production process are not included in the analysisc. because of legal factors, the long-run cost curve derived by this technique may be distorted and may not measure the cost curve postulated in economic theoryd. a and be. b and c

a. trueb. false
10. A linear total cost function implies that:
