This paper generalizes the classical existence results for games with discontinuous payoffs, developed by Dasgupta and Maskin in 1986. This new existence result is then applied to a simple duopoly model with quantity precommitment and Bertrand competition. Copyright 1997 by Blackwell Publishing...

Within a standard three-tier regulatory model, a benevolent prin- cipal delegates to a regulatory agency two tasks: the supervision of the …rms (two-type) costs and the arrangement of a pricing mecha- nism. The agency may have an incentive to manipulate information to the principal to share the...

Do the citizens have a role in constraining policies in autocratic governments? Usually the political and economic literature model autocracy as if the citizens have no role in constraining leader’s behavior, but actually autocratic government are afraid of possible citizens’ revolts. In...

Questo saggio si propone come ausilio metodologico per favorire la discussione e la comparazione di approcci alternativi alla contaminazione tra economia, psicologia e scienze sociali in genere. Il suo scopo specifico Š di esemplificare le modalita' di fertilizzazione incrociata tra queste...

This paper deals with the problem of specifying a general learning model, the rationality of which is not situation dependent. I propose a very general model of adaptive learning suitable to study learning problems in games with imperfect monitoring, such as extensive form games. In this context...

This paper provides a general framework for analysing rational learning in strategic situations in which the players have private priors and private information. The author analyses the behaviour of Bayesian rational players both in a repeated game and in a recurrent game when they are uncertain...

This paper provides a genera1 framework to analyze rational learning in strategic situations where the players have private information and update their private priors collecting data through optimal experimentation. The theory of statistica1 inference for stochastic processes and of Markovian...

Admissibility, i.e. the deletion of weakly dominated strategies, is a highly controversia1 solution concept for non cooperative games. This paper proposes a complete theory of weak dominance and, contrary to almost al1 the literature on this topic, it provides positive results on foundations of...

The purpose of this paper is to explore the joint work of two mechanisms that might constrain autocratic rulers: the threat of a coup by the political elite and of a revolution by the citizens. Our results will help explain a well-established and crucial fact, that is, that autocracies are far...
