Research Interests

The academic core of my research is applied welfare economics, centering on the use of surveys and experimental situations to understand how individuals make decisions affecting their economic welfare. The work is based in environmental economics, safety economics and health economics.

Key interests: Environmental Economics (non-market valuation), Experimental Economics, Safety Economics, Health Economics
