This paper uses a field experiment to investigate the quality of individuals’ forecasts of relative performance in tournaments. We ask players in luck-based (poker) and skill-based (chess) tournaments to make point forecasts of rank. The main finding of the paper is that players’ forecasts...

We assess the determinants of Chinese direct investment in Africa compared with those of global FDI. We find that economic size and macroeconomic stability are positively correlated with Chinese and global FDI in Africa. Institutional variables, such as accountability and rule of law, are not...

Antonio Manuel Pinto Barbosa (1917-2006), economist and official, was included by Expresso Revista among the 100 Portuguese who shaped the 20th century. He has been biographed by Joao Cesar das Neves and Francisco Azevedo e Silva in a book published in 1999, whose chapter 7 calls him the dean of...

This paper aims at building a theoretical framework to examine the impact of development pressure on private owner’s forest management practices, namely, on regeneration and conversion cut dates. As the rent for developed land is rising over time, our model creates the possibility of switching...

Este artigo apresenta um resumo dos principais resultados da teoria de integragco e cointegragco fraccional. Apesar do conceito de integragco fraccional ter sido objecto de particular interesse em diferentes areas do conhecimento, ss muito recentemente este passou a merecer a atengco dos...

We present a puri¯cation result for incomplete information games with a large ¯nite number of players that allows for compact metric spaces of actions and types. This result is then used to generalize the puri¯cation theorems of Schmeidler (1973), Rashid (1983) and Kalai (2004). Our proofs...

In this article the authors develop a new measurement scale (the RELQUAL scale) to assess the degree of relationship quality between the exporting firm and the importer. Relationship quality is presented as a high order concept. Findings reveal that a better quality of the relationship results...

The endogenous formation of coalitions involving asymmetric firms and their stability are analyzed as a function of diferences in eficiency and of the mixed cost of production. Results are derived for cartels as well as for mergers. Players have constant but diferent marginal costs of production...

Until now, in models of endogenous growth with physical capital, human capital and R&D such as in Arnold [Journal of Macroeconomics 20 (1998)] and followers, steady-state growth is independent of innovation activities. We introduce absorption in human capital accumulation and describe the...

This paper discusses a model where consumers simultaneously differ according to one unobservable (preference for quality) and one observable characteristic (location). In these circumstances nonlinear prices arise in equilibrium. The main question addressed in this work is whether firms should...
