Research on problem solving drawing on the Carnegie School suggests that if a problem is of elevated complexity an appropriate representation is key to tackling it. However, when an appropriate representation is not in the decision maker's knowledge base, it is unclear what determines whether...

This paper applies the theory of aspiration adaptation to industrial economics. It is motivated by the question, frequently raised in the context of theoretical and empirical research on industrial innovation, of what triggers a firm's innovative activity. We develop a model of the management's...

A model of new-product diffusion is proposed in which a site-percolation dynamics represents socially-driven diffusion of knowledge about the product's characteristics in a population of potential buyers. A consumer buys the new product if her valuation of it is not below the price of the...

The dynamics of individual characteristics of economic agents is modeled with the link structure influenced by this dynamics: links between agents with similar characteristics are more stable than those between agents with vastly different characteristics. A simple scaling law describes the...
