real networks. A second aim is to introduce the adaptive interactive expectations (AIE) model, which uses a ‘pressure to … change profit expectations index’ to replace the utility curve maximising agent concept. The AIE model has an interactive … expectations network, which is difficult to determine, so suitable to illustrate network averaging. The AIE model is tested against …

We study a financial market populated by heterogeneous fundamentalists, whose decisions are driven by ``animal spirits''. Each agent may have optimistic or pessimistic beliefs about the fundamental value, which are selected from time to time on the basis of an evolutionary mechanism. The...

In modeling expectation formation, economic agents are usually viewed as forming expectations adaptively or in … accordance with some rationality postulate. We offer an alternative nonlinear model where agents exchange their opinions and …, we show that this kind of model performs well in simulation experiments. Focusing upon producers' expectations in the …

In this paper we provide a sufficient condition for a social welfare relation to be a social decision relation (i.e. an acyclic social welfare relation) when the profile of individual preferences is given.

In this paper, I develop a hybrid model that contains elements of both agent based simulations (ABS) as well as analytic Cournot models, to study the effects of firm characteristics, market characteristics, and innovation on market concentration, as measured by a Herfindahl-Hirschman Index...

This paper provides a general overview of theories and tools to model individual and collective decision-making. In particular, stress is laid on the interaction of several decision-makers. A substantial part of this paper is devoted to utility maximization and its application to collective...

This study investigates social welfare and privatization depending on the government's preference for tax revenues and the timing of wage setting in either a unionized-mixed or a unionized-privatized duopolistic market. We show that bargaining over wages is always sequential regardless of who...

We describe a candid model for learning, why and how learning transpires. We investigate the original as well as the leading conditions of the learning process. We provide an insight into the realm of beliefs and their formation, their interaction and influence with the actor’s environment. In...

Models of rational choice use different definitions of rationality. However, there is no clear description of the … latter. We recognize rationality as a conceptual conglomerate where reason, judgment, deliberation, relativity, behavior …, experience, and pragmatism interact. Using our definition, the game theoretic idealized principle of rationality becomes absolute …
