In this paper,we consider the transparency of monetary policy in a New Keynesian model with misspecification doubts. Model uncertainty allows us to identify a new source of central bank opacity, which refers to a lack of information about central bank’s preference for model robustness. Thus,...

We present, a relatively new and unpublished concept here : the " ba ". This one is advanced by two authors : I. Nonaka and N. Konno [1998]. They show that this concept - shape of place where take place interactions - is a foundation of creation of new knowledge in an organization. Our...

This paper explores the impact of diversity of innovative strategy of firms upon the industrial dynamics through a micro-simulation model. We consider two types of firms each one being characterised by a specific innovative strategy. Basically we assume that some cumulative firms adopt an...

Cette contribution se propose de tester la substituabilité entre Etat et famille dans la prise en charge du chômage dans dix pays européens. Après avoir estimé ce que pourrait être le gain estimé des chômeurs, nous utilisons cette base de comparaison pour analyser le pourcentage du...

This paper examines a model of financial and exchange crises with balance-sheet effects by explicitly taking account of wealth accumulation and external equilibrium condition. We have found that, in a general equilibrium analysis, there are two stationary equilibria. Since foreign debt is always...

We show that experimental subjects tend to contribute more to the public good if they perceive the actions of the others as a source of positive externality rather than a source of negative externality. In our experiment partial contribution to the public good is the unique subgame perfect...

Ce travail définit la notion de processus entrepreneurial dans un cadre évolutionniste. Il apporte un éclairage sur la formation de la firme et de l’organisation. En ouvrant la « boîte noire » du processus entrepreneurial, nous montrons que ce mécanisme peut être découpé en étapes...

In this paper, we say a few words about the context, role and classification of Origin-Destination (O-D) matrix determination procedures, with a view to situating existing research streams within a common framework. We distinguish between O-D matrix derivation approaches and proper O-D matrix...

In their paper on Best-Reply Matching (BRM), Droste, Kosfeld & Voorneveld (2003) obtained quite intuitive results for the centipede game. In this short paper we first show that these results derive from the application of their criterion to the reduced normal form of the game. Then we prove that...
