Última INCOME REMINDER AND THE DIVERGENCE BETWEEN WILLINGNESS-TO-PAY ESTIMATES ASSOCIATED WITH DICHOTOMOUS CHOICE AND OPEN-ENDED ELICITATION FORMATS AgEcon He, Senhui; Jordan, Jeffrey L.; Florkowski, Wojciech J.. This study investigates whether an income reminder can reduce the divergence between the willingness-to-pay (WTP) estimates associated with the open-ended (OE) and dichotomous choice (DC) elicitation formats. Results show that without an income reminder, WTP estimate associated with DC elicitation format is about 1.66 times as large as that associated with OE elicitation format. With an income reminder, the WTP estimate associated with DC format decreased while the WTP estimate associated with OE format increased, and the divergence between the WTP estimates was almost eliminated.

Ano: 2003 URL: http://purl.umn.edu/35193 The Role of Participation in CVM Survey Design: Evidence from a Tap Water Improvement Program in Northern Thailand AgEcon Ahlheim, Michael; Fror, Oliver; Sinphurmsukskul, Nopasom. In the environmental economics literature results from contingent valuation mail surveys (MS) are usually considered less reliable than results from face-to-face surveys (FtF). This is mostly due to low response rates and self-selection effects of the respondents. However, MS are much less costly than FtF surveys so that there exists a strong need to make MS more reliable in order to save costs for environmental policy makers. This paper proposes a participatory procedure of survey design in order to improve MS questionnaires. In an empirical study of water quality improvement it is demonstrated that this procedure yields results identical to those of a FtF survey. In contrast to focus groups commonly applied in contingent valuation, we are able to show...
