Dr. Colby's research is in natural resource and environmental economics
and in public policy, and in particular, water resource economics.
Some of her current projects involve nonmarket valuation of natural
amenities, analyzing transactions costs generated by regulatory
policies, evaluating the reallocation of water resources among
economic sectors, economic tools to resolve environmental conflicts,
and identifying strategies to promote efficient allocation of
risk associated with variability in water supply and water quality.
