Abstract
This article provides a broad overview of the interplay among cognition, belief systems and institutions, fleshing out a position best characterized as 'cognitive institutionalism'. We argue that a deeper understanding of institutions, emergence, their working properties and their effect on economic performance should start with the analysis of cognitive processes. Exploring the nature of individual and collective learning the article suggests that the issue is not whether agents are perfectly or boundedly rational, but rather how human beings actually reason and choose. We also show how a full treatment of the phenomenon of path dependence should look like; there is a path dependence at the cognitive level, at the institutional level and at the economic level and there are links among them.
