This was the text for EVSP 502 Environmental Economics.
p. 55. The scale of environmental problems in capitalist economies like the United States often pales next to the devastation wrought in socialist economies like the former Soviet Union.
p. 84. Many people assume that natural resources have infinite value. But economics does not,
p. 86. Stanley Jevons, a renowned nineteenth century British economist, predicted in a book called The Coal Question that as Britain depleted its coal reserves, its economic power would decline precipitously. Jevons failed to account for the fact that an increase in the price of coal would spur the development of alternative sources, new extracting technologies, and greater efficiency in coal use, and he failed to anticipate the rise of oil and natural gas as alternative fuels.
p. 92. When resources are limited, current consumption comes at the cost of foregone potential future consumption. The present value (at the margin) of these foregone future consumption opportunities is marginal user cost, or scarcity rent.
p. 114. Notice that the fishery is economically overfished before it is biologically overfished. This will always be true because fishing is costly.
p. 115. Here again, actors in a market generate costs (fish depletion) that are external to the transactions between buyers and sellers. No individual fisher has an incentive to account for the externality of depletion of the fish stock
p. 136. A tax on pollution equal to the marginal damage at the socially efficient level of pollution will achieve the socially efficient outcome.
p. 137. What is the Optimal Gasoline Tax? . . . They found that the Pigouvian tax reflecting marginal external costs would be eighty-three cents per gallon in the United States. . . . Taxing gasoline, therefore, is just an (imperfect) proxy for taxing miles driven.
p. 138. The marginal cost and benefit functions look an awful lot like supply and demand curves.
p. 139. The role of government policy, then, can be understood as filling in the missing demand curve.
p. 140. In effect, a tax on pollution amounts to charging firms for what they would pollute in the absence of regulations, and then paying them back for every ton they abate. . . . The tax and the cap-and-trade policy are essentially different ways of getting to the same point.
p. 197. Concerns about distributional equity could be addressed by combining drought pricing with income transfers.
p. 198. In contrast, drought pricing involves simply changing the price of water.
p. 199. . . . the "dead zone" in the Gulf of Mexico, and we have determined that the two main causes are farming upstream of the Mississippi Delta and municipal sewage plant discharge from cities in the delta.
