State-level building energy codes have been around for over 40 years, but recent empirical research has cast doubt on their effectiveness. A potential virtue of standards-based policies is that they may be less regressive than explicit taxes on energy consumption. However, this conjecture has...

We develop an empirical approach to value changes to a climate in terms of total market output given optimal factor allocations in general equilibrium. Our approach accounts for unobservable heterogeneity across locations as well as the costs and benefits of adaptation in climates of arbitrary...

Economic theory suggests that demand is more elastic in the long run relative to the short run, but evidence on the empirical relevance of this phenomenon is scarce. We study the dynamics of residential electricity demand by exploiting price variation arising from a natural experiment: the...

The Samaritan's dilemma posits a downside to charity: recipients may rely on free aid instead of their own efforts. Anecdotally, the expectation of free assistance is thought to be important for decisions about insurance and risky behavior in numerous settings, but reliable empirical evidence is...

We estimate the causal effects of acute fine particulate matter (PM 2.5) exposure on mortality and health care use among the US elderly using Medicare administrative data and a novel instrument for air pollution: changes in the local wind direction. We then develop a new methodology that uses...

It is widely hypothesized that incomes in wealthy countries are insulated from environmental conditions because individuals have the resources needed to adapt to their environment. We test this idea in the wealthiest economy in human history. Using within-county variation in weather, we estimate...

Hurricane Katrina destroyed more than 200,000 homes and led to massive economic and physical dislocation. Using a panel of tax return data, we provide one of the first comprehensive analyses of the hurricane's long-term economic impact on its victims. Katrina had large and persistent impacts on...

Global warming has become a controversial public policy issue in spite of broad scientific consensus that it is real and that human activity is a contributing factor. It is likely that public consensus is also needed to support policies that might counteract it. It is therefore important to...

This paper provides empirical evidence of advantageous selection in insurance markets. By using a novel insurance setting where moral hazard is not a concern, I am able to overcome an important obstacle in most studies of selection: the inability to distinguish moral hazard from selection. In...

We know little about the dynamic economic impacts of natural disasters. I examine the effect of hurricanes on US counties’ economies 0-10 years after landfall. Overall, I find no substantial changes in county population, earnings, or the employment rate. The largest empirical effect of a...
