Book Description
This paper extends Weitzman's (1974) "Prices vs. Quantities" to allow for incomplete enforcement. Whether the regulator uses prices (e.g., taxes) or quantities (e.g., tradeable quotas), a first-best design is always inefficient in the presence of incomplete enforcement. A second-best design that incorporates incomplete enforcement, and where cost and benefit curves are known with certainty, can be implemented equally well with either instrument. If benefit and cost curves are uncertain, however, a quantity instrument performs better than a price instrument. In fact, if the slopes of the marginal cost and marginal benefit curves are equal, quantities are always preferred over prices. Results are consistent to alternative enforcement policies.

Book Description
This paper considers how policy updates and trading of regulated quantities over time changes the traditional comparative advantage of prices versus quantities. Quantity regulation that can be traded over time leads firms to set current prices equal to expected future prices. A government seeking to maximize net societal benefits can take advantage of this behavior with a sequence of quantity policy updates that achieves the first best in all periods. Under price regulation where current prices remain fixed until future policy changes occur, no such opportunity exists to achieve the first best, and prices are never preferred. However, if we assume policy updates are driven in part by political "noise" rather than maximizing net societal benefits, the result changes and prices can again be preferred. The comparative advantage now depends the relative variance of noise shocks compared to true cost and benefit shocks. This contrasts sharply with the traditional comparative advantage that depends on the relative slopes of marginal costs and benefits. Applied to climate change, we estimate the comparative advantage of intertemporally tradable quantities (over prices) to be $2 billion over five years. This estimate grows if updates occur less frequently or could be made negative by political noise.

Book Description
In a market subject to environmental regulation, a firm's strategic behavior affects the production and emissions decisions of all firms. If firms are regulated by a Pigouvian tax, changing emissions will not affect the marginal cost of polluting. However, under a tradable permits system, the polluters' decisions affect the permit price. This paper shows that this feedback effect may increase a strategic firm's output. Relative to a tax, tradable permits improve welfare in a market with imperfect competition. As an application, I model strategic and competitive behavior of wholesalers in the Pennsylvania, New Jersey, and Maryland electricity market. Simulations suggest that exercising market power decreased local pollution by approximately nine percent, and therefore, substantially reduced the price of the region's pollution permits. Furthermore, I find that had regulators opted to use a tax instead of permits, the deadweight loss from imperfect competition would have been approximately seven percent greater.

Book Description
This paper extends Weitzman's (1974) seminal paper comparing price and quantity instruments for regulation to consider a third option: tradable quantity regulations, such as tradable permits. Contrary to what prior work has suggested, fixed quantities may be more efficient than tradable quantities if the regulated goods are not perfect substitutes, even when trading ratios are based on the ratio of expected marginal benefits between goods, not simply one-for-one. Indeed, when benefits are independent across goods, or when the goods are complements, tradable quantities are never the most efficient instrument. This theory is applied to dynamic pollution problems, and suggests that permit banking should be allowed for stock pollutants, but not for flow pollutants. These results indicate that many regulations, including the current sulfur dioxide trading program and proposed greenhouse gas regulations, are inefficient
