ABSTRACT

In this chapter we outline the principal sources of bias in contingent valuation studies, the conditions that promote their occurrence, and approaches that may be used to minimize their effects. Our intent is to convey a sense of the variety and subtlety of systematic error and of the ways in which these biases can and should be taken into account in the design and execution of a CV study. Susceptibility to particular biases will vary greatly according to the nature of the amenity being valued.
