Financial time series analysis has focused on data related to market trading activity. Next to the modeling of the conditional variance of returns within the GARCH family of models, recent attention has been devoted to other variables: first, and foremost, volatility measured on the basis of...

In questo articolo si sviluppa un nuovo approccio per il calcolo del Value-at-Risk che utilizza il Filtro di Kalman per stimare il beta dei titoli di un portafoglio. Tale tecnica viene applicata al portafoglio azionario di una società assicurativa e confrontata con i metodi tradizionali basati...

In this paper we address the issue of forecasting Value–at–Risk (VaR) using different volatility measures: realized volatility, bipower realized volatility, two scales realized volatility, realized kernel as well as the daily range. We propose a dynamic model with a flexible trend...

The Multiplicative Error Model introduced by Engle (2002) for non-negative valued processes is specified as the product of a (conditionally autoregressive) scale factor and an innovation process with positive support. In this paper we propose a multivariate extension of such a model, by taking...

The explosion of algorithmic trading has been one of the most prominent recent trends in the financial industry. Algorithmic trading consists of automated trading strategies that attempt to minimize transaction costs by optimally placing orders. The key ingredient of many of these strategies are...

The purpose of this work is to build a quali-quantitative method for measuring the endogenous performance in R&D organization which supports the process of evaluation. The method is tested on Cnr Institutes of Piemonte, a highly industrialised region in North Western Italy and the score of...

The purpose of this study was to investigate the contributions of Social Identify Theory’s variables to research performance. Regression models were applied on data of ten national research Council (Cnr) institutes of Piemonte, a highly industrialised region in North Western Italy.Results show...

Aim of this paper is to analyse the spatial aspects of technology transfer (t.t.) in Cnr Institutes of Piemonte, a highly industrialised region in North Western Italy. The specific purpose is to verify two hypotheses 1) If the spatial propagation of t.t. follows the Hägerstrand...

Italian Abstract: Il lavoro esamina le caratteristiche delle imprese multinazionali italiane e ne confronta la performance con quella delle altre imprese nei quattro anni successivi alla crisi del 2008. La quota di imprese industriali con almeno 20 addetti che operano anche all’estero è in...

The transmission mechanisms of volatility between markets can be characterized within a new Markov Switching bivariate model where the state of one variable feeds into the transition probability of the state of the other. A number of model restrictions and hypotheses can be tested to stress the...
