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...

The sample selection model is based upon a bivariate or a multivariate structure, and distributional assumptions are in this context more severe than in univariate settings, due to the limited availability of tractable multivariate distributions. While the standard FIML estimation of the...

The use of the contingent valuation method (CVM) policy analysis has grown significantly in the last two decades, with applications to a variety of public goods. The primary purpose of this paper is to present an application of the CVM to the valuation of projects for the improvement of some...

Since Soviet times Lake Ülemiste has been closed to public access. The current practice of Tallinn may entail unnecessary losses of benefits to the local population. The aim of this paper is to find the value of the foregone benefits. In order to find this value, a contingent valuation (CVM)...

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 nonparametric estimations of the mixture model. We consider...

Colombia has the greatest bird diversity of any country in the world, with approximately 20% of all bird species worldwide. Advances made by the Colombian government to end long-standing armed conflict and to promote ecotourism can help position Colombia as one of the most important bird...

This paper investigates the role of congestion in influencing the site choice of recreation participants and derived values for a trip. Estimation is performed in a revealed preference framework by constructing an instrument for congestion within the estimation using the predicted choices of...

The purpose of this paper is to establish whether the unobserved spatial interdependencies between individual households influence recreational travel choices. To coherently incorporate spatial interdependencies in the behavioral analysis, we propose spatial random utility model of recreation...
