The paper discusses the role of self-organizing phenomena like emergence of infrastructure and self-organizing criticality in a spatial economy. Some theoretical models are discussed and reviewed. Computer models in the form of simple cellular automata, similar to the game "Life" and Schelling's...

The spatial model of voting is a benchmark in theories purporting to explain political behavior. Yet, evidence against the accuracy of both the assumptions and predictions of the spatial model is accumulating in the scholarly literature. One long-held result of spatial theory is that incumbents...

The study of learning in games encompasses two research lines: (1) explaining the aggregate stability of classes of games when players use inductive reasoning, and (2) explaining the learning rules used by actual players. We mix approaches by considering both stability and learning rules in...

In the present paper I introduce the revelation principle of bounded rationality. The principle states that any behavior that a model of bounded rationality exhibits can be implemented as the choice of an agent with preferences and beliefs consistent with Savage-Bayesian rationality. The...

It is sometimes thought that philosophers have little to offer those who think about the science of complex systems. There are, however, two philosophical ideas that seem crucial in considering the very definition of complexity. The first is the distinction between "ontology" and "epistemology",...

Incomplete information, local interaction, and random matching games all share a common structure. A type or player interacts with various subsets of the set of all types/players. A type/player's total payoff is additive in the payoffs from these various interactions. This paper describes a...

The last decade has seen a resurgence of interest in issues of inequality by the economics profession. The sources of this increased interest are straightforward to discern. First, both increasing cross-section wage inequality as well as the apparent intractability of inner city poverty have...

Replicator dynamics and computer simulation techniques are used to construct a reduced form model which explores negative and positive feedback processes between firm costs and market shares embodied in the dynamics of (dis)economies of scale. After reproducing the standard equilibrium results...

In the framework of the median voter theorem, an ideologically driven candidate can fully alter policy when running against a vote-maximizing oponent. When turnout is allowed to depend on the relative positioning of the ideal points of the candidates relative to the voter, this result need not...
