| Valuation of environmental regulations and policy changes is usually focused on the achievement of economic efficiency or potential Pareto improvement (PPI): a proposed change or policy is accepted if those who gain from carrying out a specific project or policy could, in principle, compensate those who lose from implementing that policy so no one is worse off. Aggregate measures of value such as aggregate willingness to pay are common measures of economic efficiency. However, in reality, compensations by the gainers to the losers of a policy seldom take place and the disadvantaged must bear most if not all the cost of the adverse effects of the policy change or environmental degradation. Furthermore, willingness to pay is largely dependent on the ability... |

| This paper addresses conceptually and empirically some of the biases commonly associated with contingent valuation (CV) elicitation of willingness to pay (WTP) values for non-market goods and services. More specifically, the study focuses on testing for scope, context, and sequence effects in CV mail surveys as well as the assumption of well-defined preferences in mail questionnaires and how this assumption might bias WTP estimates. Our results suggest that the absence of scope effects in the some CV mail surveys might be a result of the complexity or multidimensional aspect of the policy in question (i.e. dredging with and without dam removal) and the assumption that increases in scale of the public good are easier to be comprehended and then translated... |
