This paper models the role of the fiscal policy and the behaviour of the budget deficit in a continuous time stochastic economy. The model is developed in a general equilibrium framework, integrating the optimisation behaviour of representative consumer and the intertemporal resource constraint...

Over the years, several formalizations of games with a continuum of players have been given. These include those of Schmeidler (1973), Mas-Colell (1984) and Khan and Sun (1999). Unlike the others, Khan and Sun (1999) also addressed the equilibrium problem of large ¯- nite games, establishing...

We show that every bounded, continuous at infinity game of perfect information has an "!perfect equilibrium. Our method consists of approximating the payoff function of each player by a sequence of simple functions, and to consider the corresponding sequence of games, each differing form the...

Fiscal decentralisation is a hot issue worldwide. Within the European Union, there are even opposing tendencies with respect to the assignment of responsibilities between government tiers. This is a textbook paper aiming to provide a pedagogic introduction to the economics of government...

This paper is an empirical application that combines averting behavior with contingent valuation data. Consistency tests are performed incorporating alternative heteroscedastic structures in the bivariate probit models by taking advantage of the different information content that characterizes...

While building on the contingency theory, this paper proposes a conceptual framework that links five factors: a) internal forces, b) external forces, c) past web and firm performance, d) current web and firm performance, and e) e-marketing strategy in terms of the strategy defined for the 4Ws...

This paper discusses how new competitive landscapes invite organizational scholars and practitioners to adopt a new organizational mindset. The proposed new mindset does not negate the importance of the traditional functions of management, but invites a reexamination of how they are expected to...

We study whether we can weaken the conditions given in Reny [4] and still obtain existence of pure strategy Nash equilibria in quasiconcave normal form games, or, at least, existence of pure strategy "!equilibria for all " 0. We show by examples that there are: 1. quasiconcave, payoff secure...

For Portugal, the transition to the Euro began in September 1989 and featured three successive institutional arrangements related to the Exchange Rate Mechanism of the European Monetary System: shadowing it, belonging to it with 6% and then with 15% fluctuation bands. Using daily data, we study...

We present a qualitative analysis of organizational improvisation and provide a preliminary insight into the following question: how is improvisation present in tightly controlled work environments? We conducted in situ observations of, and interviews with, several emergency medical teams and...
