Teaching and Research Interests
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.
