Keywords: Policy evaluation Demand analysis Food Policy Consumer behaviour Statistics for marketing and consumer research

1) Demand Analysis and Consumer Behaviour: Market surveys, primary data collection, multivariate statistical analysis, habits and addiction in consumer behaviour, consumer response to information, shocks and advertising, structural change, integration of economics and cognitive sciences in consumer research

2) Economic and Policy of Obesity and Nutrition: economic policies to tackle the adverse effects of obesity, modelling the nutrition-health relationship and its economic impacts, child obesity and the role of marketing

3) Applied Econometrics: structural time series systems (time-varying parameter models), Cointegrated Vector Error Correction Models, testing for structural breaks, discrete choice and censored models, event study analysis

4) Economic policy: monitoring and evaluation of economic policies, impact of food safety regulations, cohesion and rural development


A) Survey planning with a focus on food consumption behaviour, questionnaires based on economic psychology teories (e.g. Theory of Planned Behaviour, Prospect Theory, Food Psychographics, Lifestyles) which allow to estimate behavioural models integrating economic determinants (prices, income, information) with other psychological factors (attitudes, social norms, etc.);
B) specification and estimation of consumer behaviour models with a focus on the role of information, risk perception, consumer trust and health issues;
C) demand models with stochastic parameters aimed at evaluating the impact of information release, with a special focus on media-enhanced food scares (e.g. mad cow crisis, bird flu, etc.);
D) consumer behaviour models for habits and addiction (e.g. alcohol and tobacco demand), intertemporal preference models, adaptive and rational expectations, rational addiction

ECONOMICS AND POLICY OF OBESITY AND NUTRITION: nutrition policy analysis in different world areas (developed and developing countries), with a special focus on the obesity epidemics, the relationship between obesity and non-communicable diseases, and economic impact assessment. Specification ande estimation of micro- and macro-economic models for the statistical evaluation of the relationship among nutrition, obesity, health and public expenditure. Evaluation of nutrition policies (nutrient taxes and subsidies, information policy, labels). 

APPLIED ECONOMETRICS: Structural time series models with a range of applications (household consumption, tourism, energy). Specification and estimation of the Almost Ideal Demand System with stochastic coefficients. Cointegration and Vector Error Correction Models with a focus on demand systems and the integration of these methods with the structural time series model. Ordered probit and logit models. Tobit models with individual threshold. Event Study Analysis for financial data. Testing for multiple structural breaks.

ECONOMIC POLICY: Economic impact assessment of the introduction of food safety standards (MoniQA project). Models for evaluating agricultural policies, detection of homogeneous rural development areas through multivariate statistics. Taxation and consumer response.
