In many fields researchers wish to consider statistical models that allow for more complex relationships than can be inferred using only cross-sectional data. Panel or longitudinal data where the same units are observed repeatedly at different points in time can often provide the richer data...

Fourteen U.S. states recently pledged to adopt limits on greenhouse gases (GHGs) per mile of light-duty automobiles. Previous analyses predicted this action would significantly reduce emissions from new cars in these states, but ignored possible offsetting emissions increases from policy-induced...

There were substantial fluctuations in the numbers of American overseas travelers, especially before World War II. These fluctuations in travel around the robust, long term upward trend are the focus of this paper. We first identify those fluctuations in the raw data and then try to explain the...

Tourism today is an activity of substantial economic importance worldwide, and has been for some time. Tourism is also of substantial economic importance in the United States, sufficient to warrant the Bureau of Economic Analysis's establishing special accounts on travel and tourism. In this...

While Americans are less healthy than Europeans along some dimensions (like obesity), Americans are significantly less likely to smoke than their European counterparts. This difference emerged in the 1970s and it is biggest among the most educated. The puzzle becomes larger once we account for...

Americans average 25.1 working hours per person in working age per week, but the Germans average 18.6 hours. The average American works 46.2 weeks per year, while the French average 40 weeks per year. Why do western Europeans work so much less than Americans? Recent work argues that these...

American workweeks are long compared to other rich countries'. Much less well-known is that Americans are more likely to work at night and on weekends. We examine the relationship between these two phenomena using the American Time Use Survey and time-diary data from 5 other countries. Adjusting...

Tourism is a fast-growing services sector in developing countries. This paper combines a rich collection of Mexican microdata with a quantitative spatial equilibrium model and a new empirical strategy to study the long-term economic consequences of tourism both locally and in the aggregate. We...

This paper shows the endogeneity of amenities plays a crucial role in determining the welfare distribution of a city's residents. We quantify this mechanism by building a dynamic model of residential choice with heterogeneous households, where consumption amenities are the equilibrium outcome of...
