Experimental Economics and Resource/Environmental Economics
My primary research interest is in using laboratory experiments to address environmental and natural resource issues. I am particularly interested in topics that have public policy implications. My current areas of research include compliance behavior and enforcement of emissions trading programs, hypothetical bias in environmental valuation techniques, local governance of communal resources in developing nations, and the design of computer-assisted water markets.
