Theory and intuition tell us that the imposition of stringent environmental policies by a given country will reduce its net exports of commodities produced using pollution-intensive industries. It is therefore surprising that many empirical studies of international commodity trade have failed to...

Technological innovations in horizontal drilling and hydraulic fracturing have enabled tremendous amounts of natural gas to be extracted profitably from underground shale formations that were long thought to be uneconomical. In this paper, we provide the first estimates of broad-scale welfare...

We show that oil production from existing wells in Texas does not respond to price incentives. Drilling activity and costs, however, do respond strongly to prices. To explain these facts, we reformulate Hotelling's (1931) classic model of exhaustible resource extraction as a drilling problem:...

This paper estimates the response of investment to changes in uncertainty using data on oil drilling in Texas and the expected volatility of the future price of oil. Using a dynamic model of firms' investment problem, I find that: (1) the response of drilling activity to changes in price...
