The paper introduces the reader to the contingent valuation method for monetary valuation of individuals preferences regarding changes to environmental goods. Approaches to the validity testing of results from such studies are discussed. These focus upon whether findings conform to prior...

Contingent valuation (CV) surveys frequently employ elicitation procedures that return interval-censored data on respondents' willingness to pay (WTP). Almost exclusively, CV practitioners have applied Turnbull's self-consistent algorithm to such data in order to obtain nonparametric maximum...

Over the past few decades the problem of eutrophication of water bodies has accelerated due to large additions of nutrients from human sources. This paper conducts a contingent valuation of household willingness to pay to reduce eutrophication impacts. The application employs the recently...

Contingent valuation (CV) surveys frequently employ elicitation procedures that return interval-censored data on respondents’ willingness to pay (WTP). Almost without exception, CV practitioners have applied Turnbull’s self-consistent algorithm to such data in order to obtain nonparametric...

Internet is quickly becoming the survey mode of choice for stated preference (SP) surveys in environmental economics. However, this choice is being made with relatively little consideration of its potential influence on survey results. This paper reviews the theory and emerging evidence of mode...

The aggregate welfare measure for a change in the provision of a public good derived from a contingent valuation (CV) survey will be much higher if the same elicited mean willingness to pay (WTP) is added up over individuals rather than households. A trivial fact, however, once respondents are...
