When there are market externalities, the market allocation of resources will not be optimal.

Group of answer choices

True

False

Expert Solution

Ans. True, when there are market externalities, the market allocation of resources will not be optimal because there will be overproduction of the good in case of a negative externality and there will be an underproduction of the good incase of a positive externality.

In case of a positive externality, the marginal social benefit exceeds the marginal private benefit but buyers and sellers while taking the decision for how much to buy/produce the good don't consider marginal social benefit but take their decisions by comparing marginal private benefit and marginal private cost. This leads to an output that is less than socially optimal level

In case of a negative externality, the marginal social cost exceeds the marginal private cost but decisions are made by comparing marginal private benefit and marginal private cost only. This leads to an output which is more than the socially optimal level.

In stratified sampling, there are two methods of sample size allocation to the strata: optimal allocation and proportional-to-size allocation. Suppose interest lies in estimating the mean of the population using ŭstrat(y). Let Vopt show the variance of ŭstrat(y) under optional allocation and Vprop show the variance of ŭstrat(y) under proportional-to-size allocation. (a) [4 marks] Show, with detailed steps, that Vopt <= Vprop. (b) [2 marks] under what conditions Vopt = Vprop? provide a proof for your answer.

Even when there are no externalities in a market, a government may still tax a good such as petrol to earn revenue. Describe what happens to each of the surpluses (including total surplus) in the market for petrol when this occurs, and why. What elasticity is the market for petrol likely to exhibit? Explain how elasticity influences the impact of the price change on total surplus.

8. When some goods are public A. The market outcome is Pareto optimal B. The market outcome is not Pareto optimal because too much of the public good is supplied. C. The market is not Pareto optimal because too little of the public good is supplied due to the free-rider problem. D. The market outcome is not Pareto optimal because government spending is distortionary.
