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...

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...

This paper investigates the empirical identification of perceived congestion and mitigating behavior using observational data. Congestion effects are identified using a procedure based upon a non-linear function of the choice attributes combined with an equilibrium condition on the sorting...

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...

We design a choice experiment comparing policies that reduce agricultural nutrient pollution and harmful algal blooms in Lake Erie and administer it to Ohio residents using an online survey panel. We compare two treatments that have been found to mitigate hypothetical bias, cheap talk and...

In order to control for censoring and the integer nature of trip demand, the use of count data models in travel cost analysis is attractive. Two such models, the Poisson and negative binomial, are discussed. Robust estimation techniques that loosen potentially stringent distributional...
