1. Consider a two period model in which a scare resource (say, oil) is allocated competitively. The demand curve in both periods is given by ?? = 100 − ?? where ? = 1,2 represents the two periods. Let the unit extraction cost be $12 per barrel. Take the discount rate to be 5%.

(a) What is the threshold stock of barrels beyond which oil is no longer scare?

(b) Now suppose you are given 100 barrels of oil to allocate over the two periods. Compute quantities, prices, consumer and producer surplus and aggregate discounted welfare.

(c) How much would a monopoly supplier of oil extract in each of the two periods and at what price? Discuss by comparing to part (a).

Solutions

Expert Solution

(c) A monopolist will make the resource scarcier by supplying less than 100 in both the periods. And price will be higher in this case. Monopolist will enjoy the scarcity rent also.

Consider a two-period model in which the consumer receives income of y in the current period and y' in the future period. Rather than imposing lump-sum taxes, the government imposes a proportional tax on consumption. In the current period the tax rate is σ and in the future period the tax rate is σ'. As a result, the government collects σc in goods in the current period and σ'c' in goods in the future period. Since G and G' are...

Consider a two-period model of mineral extraction with a 3% discount rate, in which the total supply of minerals is fixed at 100. A social planner is trying to decide how much we should consume in each period (i.e. what the efficient consumption pattern would be). Q1 is our consumption in period 1; Q2 is our consumption in period 2. Prices (P1), marginal benefits (MB1), and marginal costs of extraction (MCE1) in period 1 are: P1 = MB1 = 80...

Assume a two-time-period model for a depletable resource, with identical demand functions in each of the tow time periods (i.e. P = 10 - 0.5q). The marginal cost of extraction is also constant for each of the two time periods (i.e. MC = $3). Calculate the dynamically efficient allocations of the depletable resource across the two time period when: (i) there are 20 units of the resouce available for use in total, and (ii) there are 30 units available. Also...
