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...

Transitional societies are faced with particularly challenging and pressing problems. These usually involve the passage from a centralised, socialist-based society, to a decentralised, market-based economy. This paper addresses a somewhat different case: that of Cuba. According to the official...

This paper aims to trace the development of management accounting systems (MAS) in a Portuguese bank, where an activity based costing system (ABC) has been trialled for implementation over the past few years, as a means to improving the economy, efficiency and effectiveness of employee activity....

In this paper the new member problem faced by the regional fisheries management organisations is discussed for a typical highly migratory species: the northern Atlantic bluefin tuna. The analysis is based on simulation and optimisation results from a bio-economic model. The results, for both the...

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...

After the collapse of state socialism in Eastern Europe, management researchers devoted considerable energy to investigate ways to smooth transition to market economies. But one country of the former Soviet bloc, Cuba resisted transition and reaffirmed loyalty to communism. Little is known about...

Forest literature uses both continous and discrete time models to study forest management problems, and when carbon sequestration benefits are considered, the results obtained in both approaches are not always equivalent. This issue is relevant from a policy point of view if credits are to be...
