In the current paper we examine the role of forest carbon sequestration benefits in optimal forest management. When carbon benefits are considered not only the forested area is relevant, but also the flow of carbon between land and the atmosphere through the carbon cycle. To account for all...

Radzik (1991) showed that two-player games on compact intervals of the real line have " { equilibria for all " 0, provided that payo® functions are upper semicontinuous and strongly quasi-concave. In an attempt to generalize this theorem, Ziad (1997) stated that the same is true for n-player...

Promover a “autodescoberta” dos portugueses - levá-los a exportar mais e melhor - exige cooperação inter temporal e implica tanto avançar na agenda comunitária de Lisboa quanto enquadrar a lusofonia na parceria global para o desenvolvimento. Este argumento desenvolve-se em três...

In this research, key determinants of expected short-term export performance improvement are identified. We develop a conceptual framework that incorporates past, current and expected performance, internal and external forces of the firm, and pricing strategy adaptation to the foreign market....

This article calls for research on organizational improvisation to go beyond the currently dominant jazz metaphor in theory development. We recognize the important contribution that jazz improvisation has made and will no doubt continue to make in understanding the nature and complexity of...

We define social institutions as strategies in some repeated game. With this interpretation in mind, we consider the impact of introducing requirements on strategies which have been viewed as necessary properties for any social institution to endure. The properties we study are finite...

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...

This paper develops a framework to nonparametrically test whether discretevalued irregularly-spaced financial transactions data follow a Markov process. For that purpose, we consider a specific optional sampling in which a continuous-time Markov process is observed only when it crosses some...
