Recent developments in the study of the pehistory of the northern Mogollon and Anasazi areas of the North American Southwest are reviewed, with emphasis on the pre-A.D. 1150 period, in an attempt to identify key empirical results and incipient interpretive directions.

The collapse of ancient societies such as the Mesa Verde-region pre-Hispanic Pueblos has puzzled generations of scientists. Many explanations for particular cases have been suggested, from combinations of social, political and economic factors (Tainter 1988), to climatic factors such as drought....

One clear trend that can be discerned in the last 15 years of otherwise-rather-protean Southwestern archaeology is a growing recognition that at any given time, demographic productive, and organizational strategies can be quite variable, even within comparatively small regions; that these...

The object of the workshop was to discuss and demonstrate the modeling of artificial societies and to suggest its potential for extending our knowledge about the prehistoric Southwest. Our efforts are part of the much larger questions anthropologists have asked for generations concerning how...

Reciprocity is an ancient and important social practice that evolved in very small-scale societies. In this paper we present an abstract model of the way systems work that are organized through balanced reciprocity (Sahlins 1972:185-275). This model will help us understand the general nature of...

In this paper we build a spatial, aspiration-based model of learning in the context of Cournot oligopoly from which we want to explore the conditions that lead to the emergence of cooperation among firms. We consider an economy consisting of many identical duopolies; each duopoly is placed on a...

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...

This paper investigates the properties of a local economy in which personal connections are important in finding jobs. The complementarities in the model generate an interesting nonlinear relationship between the distribution of human capital in the economy, the characteristics of the social...
