What are the economic tradeoffs between lowincome and high-income countries in international conferences on global environmental damage?
Classify the following pollution-control policies as command-and-control or market incentive based. a. A state emissions tax on the quantity of carbon emitted by each firm. b. The federal government requires domestic auto companies to improve car emissions by 2020 . c. The EPA sets national standards for water quality. d. A city sells permits to firms that allow them to emit a specified quantity of pollution. e. The federal government pays fishermen to preserve salmon.
From an economic perspective, is it sound policy to pursue a goal of zero pollution? Why or why not?
In the Land of Purity, there is only one form of pollution, called "gunk." Table 12.14 shows possible combinations of economic output and reduction of gunk, depending on what kinds of environmental regulations you choose. $$\begin{array}{l|l|l} \hline \text { Combos } & \text { Eco Output } & \text { Gunk Cleaned Up } \\ \hline \mathrm{J} & 800 & 10 \% \\ \hline \mathrm{K} & 500 & 30 \% \\ \hline \mathrm{L} & 600 & 40 \% \\ \hline \mathrm{M} & 400 & 40 \% \\ \hline \mathrm{N} & 100 & 90 \% \\ \hline \end{array}$$ a. Sketch a graph of a production possibility frontier with environmental quality on the horizontal axis, measured by the percentage reduction of gunk, and with the quantity of economic output on the vertical axis. b. Which choices display productive efficiency? How can you tell? c. Which choices show allocative efficiency? How can you tell? d. In the choice between \(K\) and \(L\), can you say which one is better and why? e. In the choice between \(K\) and \(N,\) can you say which one is better, and why? f. If you had to guess, which choice would you think is more likely to represent a command-andcontrol environmental policy and which choice is more likely to represent a market-oriented environmental policy, choice L or M? Why?
Consider the case of global environmental problems that spill across international borders as a prisoner's dilemma of the sort studied in Monopolistic Competition and Oligopoly. Say that there are two countries, A and B. Each country can choose whether to protect the environment, at a cost of \(10,\) or not to protect it, at a cost of zero. If one country decides to protect the environment, there is a benefit of \(16,\) but the benefit is divided equally between the two countries. If both countries decide to protect the environment, there is a benefit of \(32,\) which is divided equally between the two countries. a. In Table 12.10 , fill in the costs, benefits, and total payoffs to the countries of the following decisions. Explain why, without some international agreement, they are likely to end up with neither country acting to protect the environment.
