Meier [Games Econ. Behav. 62, 53–66] shows that the universal knowledge–belief space exists. However, besides the universality there is an other important property might be imposed on knowledge–belief spaces, inherited also from type spaces, the completeness. In this paper, we introduce...

This paper analyses the decision-making processes of heterogeneous agents, when both individual preferences and group actions are taken into account. Under the assumptions of certain topologies of interactions and assuming cognitive and informational restrictions, an agent-based model is...

This paper surveys work on dynamic heterogeneous agent models (HAMs) in economics and finance. Emphasis is given to simple models that, at least to some extent, are tractable by analytic methods in combination with computational tools. Most of these models are behavioral models with boundedly...

With behavioral experiments and protocol analysis, researchers can capture cognition in action. Using behavioral experiments, they can study realized behavior, not perception or self-reports. And they can do that in a controlled laboratory environment to establish causality, curbing spurious...

This research note provides clear, unambiguous rationalization for the normative that applications of utility functions to modeling of expectations are non-robust, are, in relation to best practice, out of whack. With this inference in tow, all formal theoretical studies that apply utility...

The agent-based approach views an organization as a collection of agents, interacting with one another in their pursuit of assigned tasks. The performance of an organization in this framework is determined by the formal and informal structures of interactions among agents, which define the lines...

We study consumption behaviour in systems with heterogeneous interacting agents. Two different models are introduced, respectively with long and short range interactions among agents. At any time step an agent decides whether or not to consume a good, doing so if this provides positive utility....

Necessarily, new technical change is facilitated by the development of new technical proficiencies. Whenever the claim to `new technical change' is robust, the accompanying `new technical proficiencies' facilitate an `outcome', in respect of which `old technical proficiencies' are intractable....

We exhibit and characterize an entire class of simple adaptive strategies, in the repeated play of a game, having the Hannan-consistency property: In the long-run, the player is guaranteed an average payoff as large as the best-reply payoff to the empirical distribution of play of the other...
