In this paper, we show that, when combining revealed (RP) and stated (SP) data, for marginal changes in quality of environmental goods, rationality implies consistency, as the consistency conditions coincide with a subset of the conditions for rationality.

The long march of modernization of the Western societies tends to be presented as following a regular sequence: societies and institutions were pre-modern, and then they were modernized, eventually becoming post-modern. Such teleology may provide an incomplete or distorted narrative of societal...

This paper studies how reciprocity and inequity aversion influence the behavior of firms in imperfectly competitive markets. The paper shows that if reciprocal firms compete à la Cournot, then they are able to sustain “collusive” outcomes under a positive reciprocity equilibrium. By...

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...
