We generalize the Tobit censored regression to permit unique unobserved censoring thresholds conditioned by covariates and a set of common response coefficients. This situation , we argue, is one arising frequently in applications of censored regression and we provide three diverse examples to motivate the theory. We derive a robust estimation algorithm with three noteworthy features. First, by augmenting the observed-data likelihood with the censored observations, the estimation strategy is the same as Chib (1992) who derives Bayes estimates of the conventional censored regression. Second, by virtue of its generality, the model is applicable to a much broader set of circumstances than the conventional Tobit regression, which is nested as a special case of... |

This working paper estimates the impact on the local economy of the High Garda Natural Park of alternative management scenarios for the West Garda Regional Forest. The local economy is specialized in tourist services and strongly linked to the tourist presence and their level of expenditure. We wish to investigate the effects of the participative management strategy, which takes into account users preferences and the non-participative strategy, using the SAM multiplier analysis. The local SAM has been constructed considering three sectors: agriculture, tourism and a third aggregate sector including all the other activities. The resident population has been divided into two categories: residents employed in the tourist sector and the remaining resident... |

This study examines some of the issues that are often encountered when analysing the socio-economic information of expenditure surveys using the Colombian 1985 urban expenditure survey as an example. This study discusses the problem of estimating prices when only information on expenditures and demographic characteristics is available, the options available when aggregating commodities and defining demographic or labour information, and the advantages and drawbacks in choosing total expenditure as a proxy for income or as the metric for poverty measurement. The study also applies non-parametric density estimation as a form of exploratory data analysis and as a means to learn from the data about the most proper parametric specification. |
