Hypothetical bias is one of the main issues bedeviling the field of nonmarket valuation. The general criticism is that survey responses reflect how people would like to behave, rather than how they actually behave. In our study of climate change and emissions reductions, we took advantage of the...

Unique survey data from a contingent valuation study conducted in three different countries (China, Sweden, and the United States) were used to investigate the ordinary citizen’s willingness to pay (WTP) for reducing CO2 emissions. We find that a large majority of the respondents in all three...

This study employed a choice experiment (CE) to ascertain consumer preferences and willingness to pay (WTP) for non-market food product quality attributes. Data were obtained from a large mail survey and estimated with a random parameter logit model. The results indicate that Swedish consumers...

This paper analyzes the welfare effects of a 50 percent reduction in air pollution caused by road traffic in both Cairo (Egypt) and Rabat-Salé (Morocco) using a contingent valuation method with identical elicitation questions. Despite the fact that both the numbers of inhabitants and vehicles...

Empirical evidence suggests that people’s maximum willingness to pay for having a good is often substantially lower than their minimum willingness to accept not having it, and that this discrepancy tends to be especially large when valuing public goods. This paper hypothesizes that differences...

This paper analyzes the welfare effects of improved health status through increased water quality using a choice experiment. The survey was administered to a random sample of households in metropolitan Cairo, Egypt. We apply a random parameter logit model in the analysis and illustrate the...

Using a contingent valuation survey, people’s willingness to pay for a given risk reduction is found to be much larger when traveling by air compared to by taxi. Follow-up questions revealed that an important reason for this discrepancy is that many experience a higher mental suffering from...

Using a choice experiment survey, the marginal willingness to pay (WTP) among Swedish households for reductions in power outages is estimated. The results from the random parameter logit estimation indicate that the marginal WTP increases with the duration of the outages, and is higher if the...
