5) One of the following statements is false. Which one is it?

a) TSP and SOx come predominantly from combustion of fossil fuels in the power generation and industrial sectors of the economy.

b) Among the commonly monitored pollutants, TSP and SOx are of more concern, from a health perspective than are hydrocarbons (VOCs) and ozone.

b) benefit-cost analysis as usually practiced pays no attention to who wins and who loses.

c) there is a tendency to over-estimate costs of regulations in advance of their implementation.

d) there is a tendency to understate estimates of benefits because difficult to price benefits are often ignored.
(error in question--should be an e) answer, "all of the above" which is correct)

 

7) Which, if any, of the following statements are false?

            a) Technological advance generally results in less pollution per unit of output.

b) Materials extracted from the environment do not simply disappear when they are consumed.

c) From the perspective of economists, emissions are to be controlled independently of their impact on environmental quality and regardless of whether human externalities result.

d) Most rich (high GNP) countries have higher quality environments than do middle income countries in the $4-8,000 per capita range, despite the former's greater total production.


8) One of the following statements is false. Which one is it?

b) At the economist's optimal environmental quality, total benefits equal total costs of clean-up.

c) Environmental trade-offs (costs and benefits) are inevitable, hence should be considered, from the perspective of efficiency, in environmental policy decisions.

d) While there are many positive and negative features of voting as a means of deciding public issues, one undesirable feature of voting is that it does not allow those with very large environmental demands to express them at the expense of the majority.

(error in question--both a and b are false)


9) Environmental policy, like any policy, involves both efficiency and equity. Which of the following are correct statements about these concepts?

a) Efficiency has to do with whether benefits are greater than costs while equity has to do with how those benefits and costs are distributed among people.

            c) Policies can be efficient yet socially undesirable on equity grounds.

d) Engineers and economists use “efficiency” in the same way, as for example in energy efficiency ratings of heaters.

            e) Only a) and c) are true.

 

10) In class discussion of consumer boycotts and treaties to prevent trade in endangered species, for example with the ivory of elephants, the critical issue was seen to be:

            a) the greed of mankind in consuming species to the point of extinction.

            b) the size of the penalties against poachers.

c) the effectiveness of these policies in lowering the value of ivory, hence reducing poaching.

d) whether effective property rights exist so that the scarcity value of the elephant gets reflected in use decisions.

            e) breeding size and rates of the species under consideration, in this case elephants.

13) For the hedonic method for valuing environmental improvements to work well, a number of conditions must hold. Which of the following is not one of those conditions?
