In a preceding article we have studied the Communities of Practice and their conditions of emergence using an Agent based model of a set of agents facing a continuous flow of problems. We center now our analysis on the performance of this organizational structure in comparison with a two-level...

This paper analyses a situation where market designers create new trading platforms and traders learn to select among them. We ask whether 'Walrasian' platforms, leading to market-clearing trading outcomes, will dominate the market in the long run. If several market designers are competing, we...

This paper aims to analyze and exemplify some methodological implications on the way to conduct experiments related to the adoption of a cognitive approach in Economics. Many differences arise in relation to a more traditional way. In fact cognitive economics has strong descriptive attention and...

Is it possible to consider that the Organizational Information System (OIS) allows to articulate individual and organizational dynamics of learning ? Our aim is to answer the central question, in economics, of the cognitive transfers between the individual and the organization as a collective...

Economies are complicated systems encompassing micro behaviors, interaction patterns, and global regularities. Whether partial or general in scope, studies of economic systems must consider how to handle difficult real-world aspects such as asymmetric information, imperfect competition,...

We consider a pure exchange economy, where for each good several trading institutions are available, only one of which is market-clearing. The other feasible trading institutions lead to rationing. To learn on which trading institutions to coordinate, traders follow behavioural rules of thumb...

The rational expectations equilibrium has been criticized as an equilibrium concept in market game environments. Such an equilibrium may not exist generically, or it may introduce unrealistic assumptions about an economic agent's knowledge or computational ability. We define a rational...
