His recent research has focused on measuring the costs associated with exposure to poor air quality, the benefits associated with remediating brownfields and toxic waste under the Superfund program, and the valuation of non-marginal changes in disamenities, such as was the case with the large reductions in violent crime that occurred in many US cities during the 1990’s.
