Author's abstract. In nonlinear state-space models, sequential learning about the hidden state can proceed by particle filtering when the density of the observation conditional on the state is available analytically (e.g. Gordon et al. 1993). This condition need not hold in complex environments,...

In this paper, the authors draw from theories of cognition, in particular Piaget (1930, 1931, 1934, 1935, 1949, 1966, 1968) and provide some content analysis of Simons’ writings (1987, 1990, 1991, 1994, 1995, 2000), based on four categories, which stem from our interpretation of Piaget’s...

Inter-organizational communities of practice (IOCoPs) are today an emergent research topic and studies in this area are still in an exploratory phase. Theoretical mechanisms are vaguely specified and empirical studies are incipient. For this reason, this paper firstly aims at presenting the...

How can an organization define policy for managing its knowledge ? In this article, an integrative model is proposed : the Learning Mix. It consists of 4 interacting facets: Information Technology, Learning Structure, Knowledge Portfolio and Learning Identity.

This paper proposes an indirect inference (Gourieroux, Monfort and Renault, 1993; Smith, 1993) estimation method for a large class of dynamic equilibrium models. The authors' approach is based on the observation that the econometric structure of these systems naturally generates auxiliary equilibria...
