In a developing country such as India the contingent valuation method (CVM) cannot always provide a correct valuation of recreational use benefits of an environmental resource given the huge size of the parallel economy involving different categories of middle to upper income group families which have the capacity to move as tourists. The ‘participant observation method’ and ‘unstructured inter...

in addition to ecological values, wetlands provide many goods and services for local communities. anzali international wetland has always played the same role, but recently, besides degradations caused by population pressure, construction and operation of different infrastructures and developments in its basin, have caused considerable negative impacts on this precious ecosystem. it is obvious ...

This study uses the contingent valuation method to elicit individuals' preferences for their own and others' safety in road-traffic. Whereas one group is asked about a private safety device for themselves, other groups are asked about safety devices for their children, household, relatives and the public. Support is found for the hypothesis that individuals are not purely selfish when it comes ...

In this paper, we study starting point bias in double-bounded contingent valuation surveys. This phenomenon arises in applications that use multiple valuation questions. Indeed, response to follow-up valuation questions may be influenced by the bid proposed in the initial valuation question. Previous researches have been conducted in order to control for such an effect. However, they find that ...

Given the specific geographic and spatial location of rural areas in developing countries, to bring agrochemical to the rural farming households, it is argued, may have to come at a cost over and above the normal price it is sold in market. To this end, this work focuses on the willingness of rural farming households to pay more than the mean average regional retail price for agrochemicals in K...

I am glad to have the opportunity to respond to the fine paper by Professors Smith and Sach (2009). They raise both foundational questions concerning the justification of contingent valuation studies in the health policy area, and important implementation questions concerning the appropriate design of such studies. I will focus my attention on the question of justification. The debate about con...

This paper compares contingent values for a hypothetical landscape protection programme with respondents’ voting behaviour in an actual referendum. We use the example of a proposed increase of expenditures for landscape protection in the canton of Zurich, Switzerland. In particular we examine (i) CVM bid magnitudes of the different voter groups, (ii) relationships between qualitative response c...

OBJECTIVES Protest responses, whereby respondents refuse to state the value they place on the health gain, are commonly encountered in contingent valuation (CV) studies, and they tend to be excluded from analyses. Such an approach will be biased if protesters differ from non-protesters on characteristics that predict their responses. The Heckman selection model has been commonly used to adjust ...
