Ever since the European Commission (EC) defined what “corporate social responsibility” is, European debate has taken up the definition as given. However a brief review of literature soon highlights that the adopted definition has given rise to some relevant concerns and is not without its...

This paper deals with the problem of robust estimation in a Bayesian context. We present an overview on some families of so-called robust distributions and we prove that they belong to the family of elliptical distributions. According to this results, extensions to the multivariate case can be...

Economic theory has not paid much attention to the topic of firm financing; this lack of interest was common to the two principal macroeconomic theories, the Keynesian theory and the Monetarist one. This work considers two important exceptions to the mainstream theory. The first coincides with...

Recent trends in Europe have given rise to some ethical concerns. Publishing a social report is a way to show organizational ethical commitment. The analysis tries to find out empirical validation of the hypothesis that this phenomenon is growing in importance. Moreover, ethical commitment is...

Minty Variational Inequalities (for short, MVI) have proved to characterize a kind of equilibrium more qualified than Stampacchia Variational Inequalities (for short, SVI). This conclusion leads to argue that, when a MVI admits a solution and the operator F admits a primitive minimization...

The following statistical study is about a series of quantitative response variables monitored three and six months after a breast operation. All patients that underwent a brest cancer operation from January 2003 untill June 2003 have been enrolled in the study. The number of patients observed...

In this paper we deal with a Fritz John type constrained vector optimization problem. In spite that there are many concepts of solutions for an unconstrained vector optimization problem, we show the possibility “to double” the number of concepts when a constrained problem is considered. In...

The recent management literature on multinational corporations (MNCs) has mainly focused on the new role played by subsidiaries within the international firms. Many scholars have underlined that MNCs tend to organise themselves along a differentiated network approach, where subsidiaries play a...

We develop a Bayesian hierarchical logistic regression model to predict the credit risk of companiers classified in different sectors. Explanatory variables derived by experts from balance-sheets are included. Markov chain Monte Carlo (MCMC) methods are used to estimate the proposed model. In...

This paper analyses the relative effects of national, international, sectoral and intersectoral spillovers on innovative activity in six large, industrialized countries (France, Germany, Italy, Japan, UK and US) over the period 1981-1995. This is done controlling for firm level effects and...
