Systematic supervision procedures have been proposed to improve contingent valuation surveying, particularly in developing countries. Surprisingly, the CV literature does not say much about the potential effects of supervision even though there is evidence of interviewer effects and social...

This paper surveys the literature on pollinator declines and related concerns regarding global food security. Methods for valuing the economic risks associated with pollinator declines are also reviewed. A computable general equilibrium (CGE) approach is introduced to assess the effects of a...

Producing biomass energy requires extensive land resources. In western Massachusetts, where almost 90 percent of former farmland is no longer in commercial use, we study factors that motivate landowners to grow biomass energy crops. A geographic information system model identifies a landowner...

The cost-effectiveness of total maximum daily load (TMDL) programs depends heavily on program design. We develop an optimization framework to evaluate design choices for the TMDL for the Potomac River, a Chesapeake Bay subbasin. Scenario results suggest that policies inhibiting nutrient trading...

The provision point mechanism mitigates free-riding behavior in economic experiments. In two contingent valuation method surveys, we implement the provision point design. We ask respondents for their perceptions about the success of the provision point mechanism. We find that respondents who...

Willingness to pay (WTP) estimation typically involves some strategy for mapping nondichotomous contingent valuation (CV) responses onto a dichotomous yes/no dependent variable. We propose a new approach to selecting which responses qualify as ‘yes.’ We apply the proposed method to...

We compare two approaches to mitigating hypothetical bias. The study design includes three treatments: an actual payment treatment, a contingent valuation (CV) treatment with a follow-up certainty question, and a CV treatment with a cheap talk script. Our results suggest that both the follow-up...
