Most prior studies have found that substituting biofuels for gasoline will reduce greenhouse gases because biofuels sequester carbon through the growth of the feedstock. These analyses have failed to count the carbon emissions that occur as farmers worldwide respond to higher prices and convert forest and grassland to new cropland to replace the grain (or… (More)
This paper develops a simple model of land use with roots in von Thunen's work. A cross-section version of the model is estimated with data from a satellite image and other geographical sources for a region in central Mexico. Parameters from the model are used to examine the effects of reduced human activity. If variables that proxy human influence are… (More)
Use of crop biotechnology products, such as genetically engineered (GE) crops with input traits for pest management, has risen dramatically since commercial approval in the mid-1990s. This report addresses several of the economic dimensions regarding farmer adoption of bioengineered crops, including herbicide-tolerant and insect-resistant varieties. In… (More)

This paper demonstrates how satellite images and other geographic data can be used to estimate the determinants of land use. A cross-section model is estimated with data from central Mexico. Parameters from the model are used to examine the effects of reduced human activity. If variables that proxy human influence are changed to reflect reduced impact,… (More)
