The launch of Viagra in April 1998 led to a historically unprecedented high usage of erectile dysfunction (ED) drugs. We test whether Viagra's introduction significantly influenced outcomes for its target population such as STD rates of older men, as well as its non-target populations, such as...

Several countries are considering extending Daylight Saving Time (DST) in order to conserve energy, and the U.S. will extend DST by one month beginning in 2007. However, projections that these extensions will reduce electricity consumption rely on extrapolations and simulations rather than...

This paper estimates indirect benefits of improved air quality induced by hydraulic fracturing, or "fracking". The recent increase in natural gas supply led to displacement of coal-fired electricity by cleaner natural gas-fired generation. Using detailed spatial panel data comprising the near...

Recently, Weather Index Insurance (WII) has received considerable attention as a tool to insure farmers against weather related risks, particularly in developing countries. Donor organizations, local governments, insurance companies, development economists as well as agricultural economists are...

Spatial distribution and leakage effects are of great policy concern and increasingly discussed in the economics literature. Here we study Europe's most aggressive recent air pollution regulation: Low Emission Zones are areas in which vehicular access is allowed only to vehicles that emit low...

Every year between 2000 and 2010, our planet lost native forests roughly the size of Costa Rica. (FAO, 2010). This rapid deforestation has dramatically changed the chemical composition of the world's atmosphere, the level of biodiversity, and the presence of vegetation key to maintaining...

We present a hedonic framework to estimate U.S. households' preferences over local climates, using detailed weather and 2000 Census data. We find that Americans favor an average daily temperature of 65 degrees Fahrenheit, will pay more on the margin to avoid excess heat than cold, and are not...

Do drivers reduce speeds when gasoline prices are high? Previous research investigating this energy conservation hypothesis produced mixed results. We take a fresh look at the data and estimate a significant negative relationship between speeding and gasoline prices. This presents a new...

Most activities in life require a certain amount of continuous time. Yet, in the traditional economic model of time allocation, the time block is not taken into account. Hence, the same amount of utility is derived from an activity regardless of whether it is performed continuously over one time...
