Although the double-bound (DB) format for the discrete choice contingent valuation method (CVM) has the benefit of higher efficiency in welfare benefit estimates than the single-bound (SB) discrete choice CVM, it has been subject to criticism due to evidence that some of the responses to the second bid may be inconsistent with the responses to the first bid. As a means to reduce the potential for response bias on the follow-up bid in multiple-bound discrete choice formats such as the DB model while maintaining much of the efficiency gains of the multiple-bound approach, we introduce the one-and-one-half-bound (OOHB) approach and present a real-world application. In a laboratory setting, despite the fact that the OOHB model uses less information than the DB approach, the efficiency gains in moving from SB to OOHB capture a large portion of the gain associated with moving from SB to DB. Utilizing distribution-free seminonparametric estimation techniques on a split-survey data set, our OOHB estimates demonstrated higher consistency with respect to the follow-up data than the DB estimates and were more efficient as well. Hence, OOHB may serve as a viable alternative to the DB format in situations where follow-up response bias may be a concern. © 2002 President and Fellows of Harvard College and the Massachusetts Institute of Technology.

The European COST Action E45 on European Forest Externalities (EUROFOREX) participants developed a set of good practice guidelines for the non-market valuation of forests, elaborating on stated and revealed preference methodologies, as well as benefit transfer and meta-analytical procedures. This article presents a summary of the guidelines

The total economic value (TEV) of two threatened Italian cattle breeds (Modicana and Maremmana) was investigated using a choice experiment survey. Most respondents (85%) support breed conservation, their stated willingness-to-pay easily justifying EU support. The high landscape maintenance, existence and future option values of both breeds (around 80% of their TEVs) suggest that incentives mechanisms are indeed needed in order to allow farmers to capture some of these public good values and hence motivate them to undertake conservation-related activities. The positive direct use values of both breeds (around 20% of their TEVs) imply that niche product markets aimed at enhancing the private good values associated with conservation could also form elements of a conservation and use strategy for these breeds.

ABSTRACT. The aim of the paper is twofold: to carry out a contingent valuation (CV) study of Napoli Musei Aperti, a cultural public good provided by the city of Naples, and to explore some alternative schemes of cultural policy. Revealing individual preferences is a necessary condition for optimal provision of public goods, and of cultural public goods as well. Moreover, assessing the use value and the passive-use values (existence, option and bequest value), tacitly comprehended by the willingness to pay for cultural public goods, provides a basic information as far as the regulatory policy issues of the cultural sector are concerned. As far as the economic evaluation of cultural public goods is concerned, only a few empirical CV studies can be mentioned. Willis (1994) quantified the user value for the Durham Cathedral; Martin (1994) valued the " Musée de la civilisation" in Quebec; Bille Hansen (1995) measured the total value of The Royal Theatre in Copenhagen; Scarpa et. al. (1998) estimated access value to the Contemporary Art Museum of the Castello di Rivoli (Turin); Whitehead , Chambers, and Chambers (1998) investigated the preservation value of an historic building located in St.Genevieve, Missouri. Frey (1997) provided a critical appraisal of CV in this area. This paper presents some results of a CV study aimed to measure holistically the total benefits accruing to the local resident from maintaining the provision of Napoli Musei Aperti, a cultural public good provided in Naples. The present application combines and extends in several ways the previous CV studies carried out in the field. The distinctive features of our CV study are retraceable in the ways we set up the scenario, executed the survey, analyzed the data set, and derived policy implications for the cultural sector.

The econometric analysis shows the usefulness of spike models when in the sample there is a large proportion of corner solutions (zero bidders); our findings also indicate that conventional logit analysis, based on the ignorance of the payment principle answers, provides a good approximation to the more complete spike model. As the effect of question formats on values is concerned, we obtained, as have others, a significant difference between discrete and continuous WTP estimates, with discrete format yielding a WTP larger than the open-ended format.The second part of the pap...
