A computational model of a retail chain is developed in which store managers continually search for better practices. Search takes place over a rugged landscape defined over the space of store practices. The main objective of this research is to determine how the amount of discretion given to...

The dynamic choice between individual and social learning is explored for a population of autonomous agents whose objective is to find solutions to a stream of related problems. The probability that an agent is in the individual learning mode, as opposed to the social learning mode, evolves over...

Two distinct learning mechanisms are considered for a population of agents who engage in decentralized search for the common optimum. An agent may choose to learn via innovation (individual learning) or via imitation (social learning). The agents are endowed with heterogeneous skills in engaging...

Empirical studies have found high correlation between entry and exit across industries, indicating that industries differ substantially in their degree of firm turnover. I propose a computational model of dynamic oligopoly with entry and exit in a turbulent technological environment. I examine...

This paper discusses the need for, the mechanics of, and some potential application of agent-based modeling and computational analysis in industrial organization.

One of the primary challenges to measuring the impact of antitrust or competition policy on collusion is that the cartel population is unobservable; we observe only the population of discovered cartels. To address this challenge, a model of cartel creation and dissolution is developed to...

This research explores how market competition influences a firm's optimal organizational structure. For this purpose, a computational model of competing multiunit firms is developed in which unit managers and corporate staff continually search for better practices, while consumers search among...

An organization is a collection of agents that interact and produce some form of output. Formal organizations - such as corporations and governments - are typically constructed for an explicit purpose though this purpose needn’t be shared by all organizational members. An entrepreneur who...

We explore the evolution of the structure and performance of a social network in a population of individuals who search for local optima in diverse and dynamic task environments. Individuals choose whether to innovate or imitate and, in the latter case, from whom to learn. The probabilities of...
