| This paper aims to measure the time pattern of multiple and resurgent food scares and their direct and cross-product impacts on consumer response. The Almost Ideal Demand System (AIDS) is augmented by a flexible stochastic framework which has no need for additional explanatory variables such as a media index. Italian aggregate household data on meat demand is used to assess the time-varying impact of a resurgent BSE crisis (1996 and 2000) and the 1999 Dioxin crisis. The impact of the first BSE crisis on preferences seems to be reabsorbed after a few months. The second wave of the scare at the end of 2000 had a much stronger effect on preferences and the positive shift in chicken demand continued to persist after the onset of the crisis. Empirical results... |

| The aim of this work is to contribute to the definition of an analytical approach for evaluating the dynamics in progress in the agricultural and rural development at a territorial level. For this purpose principal components analysis and cluster analysis were applied and the different methodological approaches reviewed. A two-stage method is also proposed. This could provide the analytical tools to simplify and interpret the results of the territorial analyses, also in order to supply a flexible instrument to policy-makers. A case-study on the Emilia-Romagna region, in Italy, is presented. |

| Theoretical models suggest that decisions about diet, weight and health status are endogenous within a utility maximisation framework. In this paper, we model these behavioural relationships in a fixed-effect panel setting using a simultaneous equation system, with a view to determining whether economic variables can explain the trends in calorie consumption, obesity and health in OECD countries and the large differences among countries. The empirical model shows that progress in medical treatment and health expenditure mitigates mortality from diet-related diseases, despite rising obesity rates. While the model accounts for endogeneity and serial correlation, results are affected by data limitations. |

| We estimate the effects of the 2005 ban on vending machines in French schools using the 1998 and 2006 INCA nutrition surveys. These surveys contain no information on the presence of vending machines in schools attended by respondents, but the adoption of a Difference-in-Difference design, and a Regression Discontinuity Design enable us to obtain indirect estimates of the policy impact. Results are consistent and suggest that the measure has had a small but significant impact on teenager nutrition, especially in terms of reduced fat intakes. |

| Together with a call for more effective and efficient regulations in the EU, there is a growing demand for transparency in the evaluation methods used to assess their effects. This paper proposes a classification of the impacts that food safety regulations can produce and discusses the quantitative methods that are used in the literature to measure those impacts. Along with the strengths and limitations of each methodological approach, this review highlights other transversal issues relevant when developing assessment strategies, like the unbalance between ex-ante and ex-post evaluation, the lack of adequate data, the difficulty of estimating the dynamic effects of regulations, and the possibility of endogenous relationships. |

| 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... |

| As the avian flu pandemic threatens Europe, consumer awareness of the theoretical possibility of contraction of the avian flu virus through consumption of chicken saw a decline in demand at the end of 2005, with peaks between 40% - 50% in Southern European countries such as Italy whilst having little impact on demand in Northern countries like the UK. Such food scares, coupled with an increasing awareness of food safety issues by the general public, highlight the importance of evaluating the perceived risks associated with food purchasing and consumption are paramount in order to provide effective policy communication in this area. There is considerable empirical evidence that different consumers respond to food risk communication in different ways.... |
