In this paper we consider financial time series from U.S. Fixed Income Market, S&P500, DJ Eurostoxx 50, Dow Jones,Mibtel and Nikkei 225. It is well known that financial time series reveal some anomalies regarding the EfficientMarketHypothesis and some scaling behaviour, such as fat tails and...

Nell’ambito della complessa riforma delle politiche di finanziamento del sistema universitario nazionale, si inserisce anche la nuova regolamentazione della ripartizione del Fondo di Finanziamento Ordinario (FFO), che vincola parte della stessa ad una specifica valutazione (ex-post) effettuata...

The new Italian regulation for the distribution of the Ordinary Financing “public” Fund (FFO) is included in the framework of the reformation of the University System financing politics. A part of the FFO is bound by a specific merit rating performed by the C.N.V.S.U. (forthcoming...

In the complex frame of the EU agriculture politics, a particular relevant aspect is given by the new regulation on durum wheat production and diffusion incentives. These subsidies are assigned according to a particular indicator (Quality Global Index - QGI), built up through a weighted mean of...

Questo lavoro, attraverso lo studio di modelli per la gestione delle risorse rinnovabili, studia giochi differenziali con orizzonti asincroni e in particolare in presenza di giocatori non perfettamente simmetrici.

We present cross and time series analysis of price fluctuations in the U.S. Treasury fixed income market. By means of techniques borrowed from statistical physics we show that the correlation among bonds depends strongly on the maturity and bonds' price increments do not fulfill the random walk...

The Minority Game comes from the so-called "El Farol bar" problem by W.B. Arthur. The underlying idea is competition for limited resources and it can be applied to different fields such as: stock markets, alternative roads between two locations and in general problems in which the players in the...

We present cross and time series analysis of price fluctuations in the U.S. Treasury fixed income market. Bonds have been classified according to a suitable metric based on the correlation among them. The classification shows how the correlation among fixed income securities depends strongly on...

Combinare insieme piu' mezzi espressivi e' divenuto sempre pi semplice grazie agli sviluppi dell'informatica. I segnali del mondo che ci circonda sono grandezze analogiche, per poter trattare queste grandezze con un elaboratore elettronico e' necessario dapprima convertirle da analogico in...

In this paper a convergence result for the BBGKY hierarchy to a Boltzmann-like equation, in the case of anelastic collision, is shown. Boltzmann-like equations are often used to model dissipative dynamical systems such as granular media. This convergence result aims to make a contribution...
