Consider a lake stocked with fish. The total value of fish caught at the lake depends on the number of fishers, as shown in the accompanying table. As the table indicates, 1 fisher can catch $36 worth of fish in a day, 2 fishers can catch a total of $66 worth of fish, 3 fishers can catch a total of $90 worth of fish, and so forth. The fishers are identical, and the opportunity cost of a day at the lake is $18 for each fisher.
(i) Complete the table by calculating the value of each fisher's catch, on average, and the social marginal benefit of the lake.
(ii) If use of the lake is nonexcludable, how many fishers come to the lake? What is the total value of their catch? What is their total cost? What is the social gain from the existence of the lake?
(iii) What is the optimal number of fishers at the lake? What is the social gain if this optimum is achieved?
(iv) What entrance fee would lead to the optimal outcome?
A natural monopoly's average cost curve i. intersects the demand curve while the average cost curve slopes downward
ii. reaches its minimum before it intersects the demand curve. iii. intersects the demand curve below the intersection of the marginal cost curve and the demand curve. A) i only B) ii only C) iii only D) i and iii E) i, ii, and iii
In the short run, with predetermined prices, when output is less than planned aggregate expenditure:
A. planned investment is less than actual investment. B. potential output is less than short run equilibrium output. C. planned investment is greater than actual investment. D. potential output is greater than short run equilibrium output.
Peter consumes bags of potato chips and cans of soft drink. The marginal utility of bags of potato chips is 10 utils per bag and the marginal utility of cans of soft drink is 50 utils per can. Potato chips cost $0.50 a bag, and a can of soft drink costs
$1.00. What should Peter do? A) Peter should eat more chips, because they cost less. B) Peter should buy more chips and less soft drink. C) Peter should buy more soft drink, because it costs less. D) Peter should buy more soft drink and fewer potato chips.
