The Deepwater Horizon oil spill in the Gulf of Mexico in April 2010 led to the deaths of 11 workers, a six-month moratorium on deepwater drilling in the Gulf, and nearly three months of massive engineering and logistics efforts to stop the spill. The series of failures before the well was...

Methane is the second most prevalent greenhouse gas and has a global warming potential at least 28 times as high as carbon dioxide. Municipal solid waste landfills are reported to be the third-largest source of anthropogenic methane emissions in the United States, responsible for 18 percent of...

We demonstrate the diffusion in use of Earth observations data in social science research. Our study is motivated by the continuing debate among policymakers over the value of the nation’s investment in Earth observations. We also consider the role of related factors including the spread of...

We extend the theory of quality-adjusted expenditure indices to estimate benefits from public investment. In particular, we model the selection of new instruments (in the form of remote-sensing devices) to enhance the longest-operating U.S. satellite-based land-observing program, Landsat. We...

We examine the problem of the intertemporal allocation of the solid waste of cities within the United States to spatially distributed landfills and incinerators, taking into account that capacity at existing and potential landfills is scarce. Amendments to the Solid Waste Disposal Act have been...
