This study uses a unique firm-level dataset to examine how falling trade costs from 1993-2001 affected entry, exit, productivity, and exporting in the Korean manufacturing sector. We verify many of the predictions of recent heterogeneous-firm models of international trade. For example, falling...

Recent years have seen mass casualties and severe property damage caused by wildland fires. With increasing housing development in natural-amenity-rich fire-prone areas, human activities not only exert intense pressures on local ecosystems, but also increase difficulties for wildland fire...

This project examines the driving forces behind the land-use change and evaluates the effects of land-use transition on soil organic carbon density and sequestration cost in China. It contributes to the literature in three aspects. First, it applies a discrete choice method to model multiple...

This study integrates economic and physical models to estimate the social costs of several commonly suggested policies (chemical-use tax and three types of conservation payments) for reducing nitrogen loads to the Mississippi River and for controlling hypoxia in the Gulf of Mexico. The economic...

This nation-scale, watershed-level analysis focuses on the major trends and the spatial pattern of land use and the impact on watershed health. We estimate a simultaneous equation system to analyze the impact of land use on aquatic health in watersheds across the United States.

A leading cause of biodiversity decline is the habitat destruction associated with urban development. We use a database of county-level land use regulations to analyze the effects of local land use regulations on land use changes. We use the results of this analysis and a species-habitat...
