In year 2000 Portugal is celebrating the 500th anniversary of the arrival to Brazil. The Portuguese overseas adventure is now five centuries old and more than one third of the Portuguese nationals are living outside their homeland; in France they are the largest foreign community.

We discuss how six dimensions of the authentizotic psychological climate explain stress and affective well-being at work, and how stress and affective well-being explain self-reported individual performance. The sample comprises 199 employees from 118 organizations. The findings indicate the...

The starting point is an interrogation about the non-broken character of the term structure of interest rates. Some arguments for that smooth character are presented here, all of which are based upon the assumption that market participants - arbitrageurs and speculators - always try to explore...

This paper is a direct response to a recent observation in the literature that managers appear to be short-term oriented when they assess the performance of an export venture (Madsen 1998). Based on a survey of Portuguese and British exporters, this paper presents a three-dimensional scale for...

We argue that it is natural to study social institutions within the framework of standard game theory (i.e., only by resorting to concepts like players, actions, strategies, information sets, payoff functions, and stochastic processes describing the moves of nature, which constitute a stochastic...

The convergence features of an Endogenous Growth model with Physical capital, Human Capital and R&D have been studied. We add an erosion effect (supported by empirical evidence) to this model, and fully characterize its convergence properties. The dynamics is described by a fourth-order system...
