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...

Given a set of continuous variables with missing data, we prove in this paper that the iterative application of a simple “least-squares estimation/multivariate normal simulation” procedure produces an efficient parameters estimator. There are two main assumptions behind our proof: (1) the...

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...

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...

Multiplicative Error Models (MEM) can be used to trace the dynamics of non–negative valued processes. Interactions between several such processes are accommodated by the vector MEM and estimated by maximum likelihood (Gamma marginals with copula functions) or by Generalized Method of Moments....

In financial time series analysis we encounter several instances of non–negative valued processes (volumes, trades, durations, realized volatility, daily range, and so on) which exhibit clustering and can be modeled as the product of a vector of conditionally autoregressive scale factors and a...
