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...

Distributional assumptions are crucial in the estimation of the value of public projects assessed by means of contingent valuations analyses, and it would seem obvious that tests for model specification should play an important part in the statistical analysis. It can be observed, though, that...

This paper presents an application of two ML models to the analysis of residential demand of water - the heterogeneity and the two-error model, both apt to model demand in presence of a kinked budget constraint. The heterogeneity model is especially suitable when the distribution is...

The present work analyses a dataset on electricity consumption in an Italian region for a period of 11 years, using aggregated data on municipalities. Our aim is to estimate the value of the price elasticity, of the income elasticity and cross-price elasticity of other fuels and to analyse the...

Preference for flexibility is a behavioral attitude displayed by people that prefer reversible to irreversible actions, and that are willing to pay a premium in order to maintain the possibility of changing their decision. This paper provides a functional characterization of preference for...

In questo lavoro si utilizza il metodo della valutazione contingente per stimare il potenziale incremento della domanda turistica nel territorio della Maddalena, in seguito alla creazione del Parco Marino. Dopo una discussione di alcuni aspetti metodologici, viene presentata l’analisi...

International experience in environmental protection planning suggests that conservation projects can be successfully realized only if associated to socio-economic promotion, while taking account of possible distortions in the distribution of benefits. Furthermore, participation of local people...

Questo lavoro presenta alcuni risultati di uno studio di valutazione contingente, condotto al fine di stimare il valore turistico di Porto Flavia - un sito fra i più interessanti del Parco Geominerario recentemente istituito in Sardegna sotto il patrocinio dell’UNESCO. Dopo aver discusso il...
