Harmful algal bIoom species are the cause of important damages to marine living resources and human beings. These marine species are primarily introduced in North-European waters through ballast water, i.e. water trans-ported across the oceans so as to keep a vessel in balance. Port authorities...

If local communities living adjacent to the elephant see it as a burden, then they cannot be trusted to be its stewards. To assess their valuation of it, a CVM study was conducted for one CAMPFIRE district in Zimbabwe. Respondents were classified according to their preferences over the elephant....

Basic services in Finnish national parks and state-owned recreation areas have traditionally been publicly financed and thus free of charge for users. Since the benefits of public recreation are not captured by market demand, government spending on recreation services must be motivated in some...

In this paper we propose a mixture model of willingness to pay distributions for contingent valuation studies. By allowing a point mass at zero, this model nests the conventional model as a special case. We discuss both parametric and non- parametric estimations of the mixture model. We consider...

Forecasts of the regional economic impacts of changes in the demand for recreation occasioned by regulatory changes, changes in the quality of the recreation experience, or changes in average trip costs require a model that links changes in these trip attributes to individual participation...

Nature based tourism is the fastest growing tourism in many parts of the world. The attitude towards conservation of nature is measured by individuals¡¯willingness to pay. This study has made an attempt to investigate the determinants of tourists¡¯willingness to pay (WTP) for biodiversity...

The forest is an important element in most countries and its multifunctional character explains its great value. This study aims at giving a monetary value to one of these functions that occupies a special place in our urban societies: the recreative use. We use the individual approach of the...

The paper presents the results of a choice experiment carried out on the visitors of the Galleria Borghese Museum in Rome. The main objective of the work is to study the relevancy of choice experiment techniques as a tool aimed at measuring economic values supplied by cultural institutions. A...

Wedevelop a multinomial logitmodel with missing information that can be used to test for hidden alternatives in random utility models and contingent valuation analysis. To illustrate our latentchoice technique, we focus on the “don’t know” responses in dichotomous choice contingent...
