The study of Artificial Neural Networks derives from first trials to translate in mathematical models the principles of biological processing. An Artificial Neural Network deals with generating, in the fastest times, an implicit and predictive model of the evolution of a system. In particular,...

The aim of this paper is to analyze the trend of poverty and income distribution in Chile in the last seventeen years, that is since 1989, when elections allowed a coalition named Concertacion and driven by Patricio Aylwin to guide the country and to put an end to Augusto Pinochets government,...

Il passaggio dal mondo dellUniversita' a quello del lavoro e' influenzato da un insieme di variabili quali la congiuntura economica, la domanda di competenze specialistiche, la preparazione acquisita, il livello di specializzazione o professionalizzazione, la flessibilita' e le precedenti...

The aim of this paper is to analyse the social capital related to those formal institutions which support organic productions in the area of Foggia. In particular, we intend to investigate the structure of the institutional network to understand if it is the most suitable to represent an...

This paper shows that linear functions of order statistics (L-statistics) based on exchangeble random samples have a Fundamental Skew distribution (Arellano-Valle and Genton, 2003). The paper also examines the exact distribution of L.statistics when the sampled population is Skew-Normal. Exact...

To give sucient conditions for Nash Equilibrium existence in a continuous game is a central problem in Game Theory. In this paper, we present two games in which we show how the continuity and quasi-concavity hypotheses are unconnected one to each other. Then, we relax the quasiconcavity...

In this paper we propose a static model describing the commercial exploitation of a common property renewable resource by a population of agents. Players can cooperate or compete; cooperators maximize the utility of their group while defectors maximize their own profit. The model provide for one...

Long Term Fixed Income Market securities present a strong positive correlation in daily returns. By using a metrical approach and considering "modified" time series, I show how it is possible to show a more complex structure which depends strictly on the maturity date.
