Resource markets are linked over time through extraction, storage, and durable demand-side investments. I show that an anticipated strengthening of environmental policy can increase emissions today through the first two linkages and can decrease them through the third. I then use a unique...

An increasingly common type of environmental policy instrument regulates the carbon intensity of transportation and electricity markets. In order to extend the policy's scope beyond point-of-use emissions, regulators assign each competing fuel an emission intensity rating for use in calculating...

Our perception of time is both nonlinear and nonstationary, which makes preference reversals possible. I decompose the sources of dynamic inconsistency into a time acceleration effect and a time compression effect. Standard economic models focus only on the second effect. I show that when the...

Conventional wisdom holds that the efficient way to limit warming to a chosen level is to price carbon emissions at a rate that increases exponentially. We show that this "Hotelling" tax on carbon emissions is actually inefficient. The least-cost policy path takes advantage of the climate...

Energy efficiency improvements "rebound" when economic responses undercut their direct energy savings. I show that general equilibrium channels typically amplify rebound by making consumption goods cheaper but typically dampen rebound by increasing demand for non-energy inputs to production and...
