Hansen's work focuses on the valuation of offsite environmental benefits and costs associated with changes in farm programs and practices. He has estimated non-market demands for improvements in environmental quality. The estimated demand functions—demands for improved wildlife habitat and water quality—are designed to be used in subsequent environmental policy analyses. Recent research has focused on the valuation of wetland ecosystem services and targeting wetland restoration funding to maximize benefits relative to costs.
