The basic role of fiat money in a dynamic economy is considered. Its role as a virtual asset whose store of value properties are the outcome of the dynamics is explored and the role of the limits on the money supply and the bankruptcy laws in bounding prices are considered. The actions of the...

In this paper, we examine the conditions that allow increased recombination to evolve in the presence of recurrent deleterious mutation. We focus on a three-locus model first studied by Feldman et al. (1980), which follows the dynamics of a modifier locus that alters the recombination rate...

Allometric scaling relationships, including the $3/4$-power law for metabolic rates, which are characteristic of all organisms, are derived from a general model that describes how essential materials are transported through space-filling fractal networks of branching tubes. The model assumes...

Computer simulation modeling for policy development in planning has had difficulty gaining a consistent foothold. Reasons for this include bad experiences with large-scale, comprehensive models (e.g., Forrester, 1969) and the lack of theory that one can quantify (Batty, 1994). Batty (1994) has...

The evolution of cooperation often requires genetic similarity among interactors. For populations that are divided into groups such that a given trait affects all group members, this requires positive assortment of individuals into groups, i.e., that individuals are more similar to other group...

The Superconducting Super Collider (SSC) is a major project promising to open the vistas of very high energy particle physics. When the SSC is in operation, data will be produced at a staggering rate. Current estimates place the raw data coming out of the proposed silicon detector system at $2.5...

We describe in detail a new and highly effcient algorithm for studying site or bond percolation on any lattice. The algorithm can measure an observable quantity in a percolation system for all values of the site or bond occupation probability from zero to one in an amount of time which scales...

Swarm is a multi-agent software platform for the simulation of complex adaptive systems. In the Swarm system the basic unit of si8mulation is the swarm, a collection of agents executing a schedule of actions. Swarm supports hierarchical modeling approaches whereby agents can be composed of...

This paper is divided into four parts. The first section (I.) consists of definitions which center on the concept of complexity. As a minimum, the terms, system, complexity, and adaptation as used in this paper need an explanation. The second section (II.) is a sketch of cultural complexity in...

This paper draws on modern psychology to argue that as humans, in economic decision contexts that are complicated or ill-defined, we use not deductive, but inductive reasoning. That is, in such contexts we induce a variety of working hypotheses or mental models, act upon the most credible, and...
