Altruistic preferences of various forms may cause difficulties in welfare economics. In the valuation of public goods, such preferences are believed to help explain the substantial non-use values found in many stated preference (SP) valuation surveys. However, studies analysing the effect of...

With the current growth in broadband penetration, Internet is likely to be the data collection mode of choice for contingent valuation (CV) and stated preference research in the not so distant future. However, little is known about how this survey mode may influence data quality and welfare...

With the current growth in broadband penetration, Internet is likely to be the data collection mode of choice for stated preference research in the not so distant future. However, little is known about how this survey mode may influence data quality and welfare estimates. In a first controlled...

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...

To avoid conflicts often associated with mandatory regulations, it is crucial to motivate and incentivize forest owners to participate in voluntary conservation programs. To investigate forest owner preferences and willingness to accept compensation (WTA) to participate, we conduct a contingent...

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...
