The magnitude of land conversion caused by biofuels expansion largely determines whether biofuels reduce net greenhouse gas emissions. To examine this issue, we model how equilibrium changes in input use and land allocation decisions respond to market- and policy-induced increases in corn...

Life cycle analysis (LCA) is the standard approach used to evaluate the greenhouse gas (GHG) benefits of biofuels. However, it is increasingly recognized that LCA results do not account for some impacts including land use changes that have important implications on GHGs. Thus, an alternative...

Life cycle analysis (LCA) is the standard approach used to evaluate the greenhouse gas (GHG) benefits of biofuels. However, it is increasingly recognized that LCA results do not account for some impacts-including land use changes-that have important implications on GHGs. Thus, an alternative...

Land use impacts of biofuel expansion have attracted a tremendous amount of attention because of the implications for the climate, the environment, and the food supply. To examine these impacts, we set up an economic framework that links input use and land allocation decisions with ethanol and...

As the United States begins to move towards putting an economic value on reducing greenhouse gas (GHG) emissions, the need for improved accounting standards becomes acute. Lifecycle analysis (LCA), which involves the systematic collection and interpretation of material flow in all relevant...

The U.S. market in subsidized commodity revenue insurance contracts has expanded rapidly since 1996. By far the most prevalent contract forms are crop-specific, rather than the whole-farm design which has a better claim to being optimal. For an arbitrary acre allocation vector, this paper...
