Testing the stability of the Benefit Transfer Function for Discrete Choice Contingent Valuation Data
Matthews, David I.; Scarpa, Riccardo; Hutchinson, W. George - Department of Economics, Waikato Management School - 2007
We examine the stability of the benefit transfer function across 42 recreational forests in the British Isles. A working definition of reliable function transfer is put forward, and a suitable statistical test is provided. The test is based on the sensitivity of the model log-likelihood to...

One and One-Half Bound Dichotomous Choice Contingent Valuation
Cooper, Joseph C.; Hanemann, W.M.; Signorello, Giovanni - Volkswirtschaftliche Fakultät, … - 2002
To reduce the potential for response bias on the follow-up bid in multiple-bound discrete choice CVM questions while maintaining much of the efficiency gains of the multiple-bound approach, we introduce the one-and-one-half-bound (OOHB) approach. Despite the fact that the OOHB model uses less...

Assessing forest management strategies using a contingent valuation approach and advanced visualisation techniques: A Portuguese case study
Madureira, Lívia; Nunes, Luis C.; Borges, José G.; … - In: Journal of Forest Economics 17 (2011) 4, pp. 399-414
The assessment of alternative forest management strategies should account not only for the private benefits to forest landowners but also for the ecological, environmental and economic benefits valued by society. There are a number of empirical valuation methods that may contribute to that...

The Copula Approach to Sample Selection Modelling: An Application to the Recreational Value of Forests
Strazzera, Elisabetta; Genius, Margarita - Fondazione ENI Enrico Mattei (FEEM) - 2004
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...
