This paper is concerned with the subject of how the three main approaches to model aggregate fluctuations are related. That is, we are interested in the relation between real business cycle models, endogenous business cycle models and sunspot equilibria models. It is shown that there exists an...

A kooperatív játékelmélet egyik legjelentősebb eredménye, hogy számos konfliktushelyzetben stabil megoldást nyújt. Ez azonban csak statikus és determinisztikus környezetben alkalmazható jól. Most megmutatjuk a mag egy olyan kiterjesztését - a gyenge szekvenciális magot -, amely...

Jól ismert tény, hogy az egyes országokban a kormányzat különböző szervezeteinek úgy kell meghozniuk és megvalósítaniuk a gazdasági fejlődést befolyásoló gazdaságpolitikai döntéseket, hogy közben korlátozott ismeretekkel rendelkeznek a gazdasági szereplők adottságairól,...

It is found that the “Theory of Moves” is adequate in a Cold War scenario, with functionally equal participants, such as the Cuban Missile Crisis. The destabilization of normal incentive systems, under power and information asymmetry, is what prevents an equilibrium from being reached, as...

We investigate experimentally whether the extent of conditional cooperation in public good games depends on the marginal per capita return (MPCR) to the public good and type of game. The MPCR is varied from 0.2 to 0.4 to 0.8. The ‘standard’ game, in which three players contribute before a...

We analyze dynamic price competition in a homogeneous goods duopoly, where consumers exchange information via word-of-mouth communication. A fraction of consumers, who do not learn any new information, remain locked-in at their previous supplier in each period. We analyze Markov perfect...

Two signaling games of monetary policy are considered: game one examines the effect of hysteresis on the labor market on the results of the repeated monetary policy game. Disciplinary effects of reputation disappear in presence of hysteresis. The second game compares weifare effects of monetary...

We propose a stylised dynamic model to understand the role of social networks in the phenomenon we call "globalization." This term refers to the process by which even agents who are geographically far apart come to interact, thus being able to overcome what would otherwise be a fast saturation...

We consider the effect of an increase in the risk from pollution. We show that in the case of a flow pollution, when the number of players is sufficiently large, the result of Bramoulle and Treich [<italic>Journal of the European Economic Association</italic>, 2009], showing that a marginal increase of risk in...
