The focus of my research has been on both the demand and supply of environmental resources.||On the demand side, much of my research has centered on developing and testing the contingent valuation method (a leading, but controversial technique of eliciting social values for environmental and other public goods), with particular applications to groundwater quality, pollution of remote mountain lakes, ecosystem protection, and "green" electricity. Through a series of NSF, EPA and USDA grants I also been active in using experimental economic methods to empirically explore single-shot public goods funding mechanisms. These two separate thrusts have been brought together in efforts to develop improved methods for comparing hypothetical contingent values with actual contributions to public goods. My research in non-market valuation techniques also includes ongoing work funded by the USDA to develop a hedonic analysis of property values for rural New York residences, so as to gauge how much rural amenities and disamenities are incorporated into housing prices.||On the supply side I have had longstanding interests in the design of environmental programs related to water quality, with particular interest in non-point source pollution and land use. Over the last decade my attention in this area has largely been directed toward evaluating voluntary pollution control policies. More recently, with funding from the EPA STAR program, I am using experimental economic methods to test the efficacy of ambient-based incentive policies to examine voluntary and regulatory approaches to control non-point source pollution. With colleagues from Cornell and Rutgers, I am also working on a project an EPA and USDA funded project to develop a pollution trading program in the non-tidal portion of the Passaic River in New Jersey.

My instruction focuses on teaching, advising, and working on environemtal and resource economics topics at all levels (Undergraduate, MS. and Ph.D.). I presently teach an introductory environmental and natural resource economics service course, for primarily natural resource and environemtnal studies majors, a M.S course on environmental and resource economics for M.S> level students across campus, and a Ph.D. level course in environmental economics.
