L’analisi di benchmarking delle aziende congressuali: un’analisi statistica a livello internazionale
Abstract: In questo lavoro sono presentati i risultati di un’analisi di benchmarking congressuale che ha l’obiettivo di valutare la posizione delle aziende italiane sul mercato mondiale. L’analisi di benchmarking ha individuato le caratteristiche rilevanti che contraddistinguono i best in class dei centri congressuali a livello internazionale, quali un elevato tasso di utilizzo della struttura, la capacità di organizzare più di un evento contemporaneamente, la flessibilità strutturale rispetto alla domanda di mercato, la capacità di ospitare eventi internazionali a carattere associativo, la disponibilità di spazi ricettivi e la capacità di offrire internamente tutti i servizi di cui necessitano i congressisti durante lo svolgimento dell’evento.

Dynamic linkages between Euro-rates bifore Stage III of European Monetary Union
Abstract: In this paper we investigate the dynamic linkages between Euro-rates in Europe during the period preceding Stage III of EMU. We focus on three “core” European countries and in contrast to existing studies the econometric analysis is developed on the basis of a structural cointegrated VECM involving jointly long and short term rates of the selected countries. This model allows to investigate in a unified framework interest rates relationships in each country and between countries; it is therefore possible to measure possible departures from the benchmark hypothesis of “full integration” which states that the expectation hypothesis of the term structure holds in each country and a properly modified version of the uncovered interest rate parity links interest rates of di.erent countries.

Statistical Analysis of Process Capability Indices with Measurement Errors: the case of Cp
Abstract: Process capability indices (PCIs) have been widely used in manufacturing industries to provide a quantitative measure of process potential and performance. While some e.orts have been dedicated in the literature to the statistical properties of PCIs estimators, scarce attention has been given to the evaluation of these properties when sample data are a.ected by measurement errors. In this work we deal with the problem of measurement errors e.ects on the performance of PCIs. The analysis is illustrated with reference to Cp, i.e. the simplest and most common measure suggested to evaluate process capability.

Dinamica Demografica, Capitale Umano e Crescita Economica nei PVS: Teoria ed Evidenza Empirica
Abstract: The aim of the paper is to perform a “theoretically based empirical analysis” concerning the impact of demographic variables on human capital accumulation and economic growth in a large sample of low/middle income countries. By comparing the empirical evidence with the predictions about the effect of demographic variables on human capital accumulation and economic growth derived by different theoretical models, we are able to “explain” the effects found and to isolate the models which seem to be more promising for the development of future research. The first part of the paper presents a theoretical review whose aim is to shortly summarize the economic literature on demography and economic growth and to explain the rationale for the inclusion of the variables used in the empirical work. The main focus is on the role of demographic variables (such as life expetancy and fertility) upon physical and human capital accumulation, and consequently on economic growth. In the second part of the paper we perform the empirical analysis using a sample of countries at different stage of development, for which data are available.We use several sources of international data providing different kinds of variables, mainly World Bank data (WDIs) and the Barro-Lee data set for measures of human capital. We address the issue of the potential endogeneity of human capital variables by using simultaneous equations modeling. We find that human capital accumulation, in particular secondary education, gives a positive contribution to economic growth and that demographic variables, especially life expectancy at birth, have a positive impact on the accumulation of secondary and tertiary education. Moreover, geographic variables, such as geographic position or the endowment of natural resources, turn out to be of paramount importance for economic growth. In the light of the results obtained, we conclude that, demography matters for growth. In addition, and especially for the Mediterranean countries, the geographic proximity to other (much more developed) West countries and the degree of integration of the Mediterranean area, may both represent an important source of sustained long-run growth.

Learning of preferences and strategies of search for goods
Abstract: A consumer choice model is suggested where individuals select out of goods according to their decision preferences in order to maximize the utility function representing their experienced preferences which they do not know, but they learn through experience. In particular each good is identified by a set of attributes and depicted as a binary values vector, while the learning of preferences is said to occur when the decision preferences approach the experienced preferences and depicted by a pure forward neural network. Numerical experiments are presented where the consumer search behaviors elicited from the sequences of choices are: experimentation or sophisticated learning, hunch, unmotivated search or naive learning, and habit.

Testing consumption risk sharing among the United States 1963-1990
Abstract: In this paper we propose a new approach for testing consumption risk sharing among a set of countries or regions, where both the long run and short run implications of the theory are simultaneously investigated within a multivariate Error Correction Model. Differently  from existing literature we explicitly address the empirical implications arising from specifying different risk aversion coefficients in the utility functions of the countries comprising the risk sharing agreement. Application to the United States over the 1963-1990 period reveals that aggregate risk plays a relevant role in explaining consumption patterns not only in the short run but over longer horizons as well. As a consequence conventional risk sharing tests have to be properly modified to account for the possibility of error correcting dynamics.

Regional consumption dynamics and risk sharing in Italy: new evidence
Abstract: In this paper we investigate the dynamics of per capita consumption among the Italian regions by focusing on the issue of global risk sharing. Differently from existing literature, for each investigated region dynamic error correction VAR models are specified with the aim of capturing both the long run and the short run dimensions of risk sharing phenomena. Regional factors in consumption dynamics are analyzed by investigatine not only the twenty Italian regions but also its four macro-regions. Empirical results obtained over the 1960-1995 period reveal: (i) the presence of geographical biases in the allocation process of resources; (ii) the occurrence of consumption insurance against incombe fluctuations due to permanent shocks; (iii) the leading role of public consumption in determining the redistribution of resources in the long run; (iv) the better insurance of southern regions against permanent shocks, mainly because of the public consumption channel.
