RESEARCH
Economics of Endangered Species Conservation
My research focuses on three main topics: the economics of endangered species conservation, nonprofit organizations, environmental regulation, and environmental public goods, and the environmental impacts of agricultural policy. I have also conducted research on a number of additional topics.

Nonprofit Organizations, Environmental Regulation, and Environmental Public Goods
My work on endangered species conservation examines incentives for conservation on private land, the effectiveness of endangered species legislation, and the impact of litigation by environmental groups on ESA implementation.

Environmental Impacts of Agricultural Policies
My work on nonprofits, regulation, and public goods has focused on: (i) The effects of lawsuits filed by environmental organizations on the behavior of regulatory agencies and on environmental outcomes, (ii) The provision of public goods by environmental groups, and (iii) The effect of environmental quality on fundraising and contributions to environmental nonprofits.
This work examines the effects of policies such as land use regulations, biofuel subsidies, and crop insurance on welfare, land use, crop choice, and environmental outcomes such as wildlife habitat and water quality .

Other Topics
I have also conducted research on topics such as carbon sequestration in private forests, irrigation decisions, fuel choice and indoor air pollution, the use of water temperature forecasts for fisheries management, and wildfire.
