We develop a model of regulation of environmental risks in a heterogeneousindustry when policy makers are sensitive to uncertainties about the processes generating the risks. Optimal source reduction capacity is shown to vary according to site suitability. Optimal source reduction capacity and...

Transgenic pest-resistant varieties are hypothesized to reduce farmers’ demand for on-farm diversity through an act of substitution, as both serve as production risk reducing instruments. This adverse agro-biodiversity impact of technology adoption might be partially counteracted by an...

This paper examines the impact of transgenic technology adoption on varietal diversity. Transgenic pest-resistant varieties are hypothesized to reduce farmers’ demand for on-farm diversity through an act of substitution, as both serve as production risk reducing instruments. This adverse...

Do transgenic crops cause agrobiodiversity erosion? We hypothesize that they increase productivity and reduce production risk and may therefore reduce farmer demand for on-farm varietal diversity, especially when only a few transgenic varieties are available. We also hypothesize that varietal...

Major externality cases are random accidents which are not adequately addressed by the deterministic environmental policy literature -­‐ that of Pigouvian taxes, abatement subsidies and cap-­‐and-­‐trade. We consider a risk-­‐neutral industry where firms control the probability...

Traditionally, disaster assistance was available on an ad hoc basis, but the 2008 Farm Act provides a standing disaster assistance program known as Supplemental Revenue Assistance (SURE). This paper introduces a theory of nested insurance to evaluate the impact on of SURE on intensification,...

We use the actual insurance records of 52,300 farmers and 11 years to estimate two sets of insurance demands. We define measures of insurance's expected returns, variance and third moment, based on observed insurance data, and infer the expected returns for those farmers that have never had an...
