Article
Individual citizens obtain political information through continuing patterns of social interaction with other citizens, but newly obtained information is evaluated in the context of previously obtained information. In particular, citizens are more likely to discount a source of new information that contradicts old information taken from other sourc...

There is a natural tension between the effects on public opinion of social networks and the news media. It is widely believed that social networks tend to harmonize opinions within them, but the presence of media may accentuate diversity by inserting discordant messages. On the other hand, in a totalitarian state where the government controls the m...
Article
This paper addresses the factors that give rise to both heterogeneous and homogeneous opinion distributions within political communication networks. We argue that the factors sustaining homogeneity and heterogeneity are not entirely symmetrical – heterogeneity is not necessarily explained by treating it as the flip side of homogeneity. Two primary...
Article
This paper tests a variety of explanations for variation in distrust of local police in the US. As with other attitudes toward the police, there is a substantial race gap in distrust of the police. Our analysis is based upon citizen survey data from 33 cities and data on policing characteristics and the city context for those same cities. It reveal...
Article
Abstract This is a report on a long-term research project about the evolution of system,of political organizations. An agent-based computer,simulation,model,is developed,with the aim of exploring the inter-connection between,tools and concepts from the field of political science with the emerging,field of complex,systems,analysis and the simu- lati...

The Politics of Attention: How Government Prioritizes Problems. By Bryan D. Jones and Frank R. Baumgartner. Chicago: University of Chicago Press, 2005. 304p. $70.00 cloth, $25.00 paper. This book is about policy change in the U.S. national government. Drawing on their exhaustive collection of policy data for the last three decades, Bryan Jones and...
Article
Recent highly publicized traffic accidents involving older drivers have led to renewed interest in state policies and administrative practices that award and renew drivers' licenses in the American states. Because the probability of traffic accidents is linked to the medical conditions that are more prevalent among the elderly, and because the numb...

Paper prepared for presentation at the Midwest Political Science Association Conference, Chicago Illinois, April, 2005. The proliferation of mixed electoral systems across the globe has spawned a growing literature assessing how these rules affect the behavior of political actors at the micro-level and partisan competition at the macro-level. Score...
Article
Abstract Agent-based models can be used to explore the impact of micro-level theories of political inter- action on aggregate patterns in public opinion. We are interested in several theories about the conditions under which people interact with and respond to one another. In this report, our cen- tral question is this: under what conditions will d...
Article
Without the experience of disagreement, political communication among citizens loses value and meaning. At the same time, political disagreement and diversity do not always or inevitably survive. This book, accordingly, considers the compelling issue of the circumstances that sustain political diversity, even in politically high stimulus environmen...

This project is a "proof of concept" exercise intended to demonstrate the workability and usefulness of computer-generated choreography. We have developed a framework that represents dancers as individualized computer ob- jects that can choose dance steps and move about on a rectangular dance floor. The effort begins with the creation of an agent-b...
Article
This paper presents an agent-based simulation model of protest activity. Agents are located in a two dimensional grid and have limited ability to observe the behavior of other agents in the grid. The model is used to explore questions inspired by research on different theories of individual motivation and the so-called theory of critical mass. The...
Article
The Santa Fe Artificial Stock Market (ASM) is a well-known agent-based model. A new revision of the code (ASM-2.2) is now available. This article describes some of the changes that were made in the code base and also presents some important lessons for agent-based modelers that can be illustrated with the code. Because the code is available on the...
Article
This paper addresses a series of questions related to the survival of disagreement among interdependent citizens during an election campaign. Do campaign-stimulated processes of collective deliberation result in the elimination of disagreement within networks of social communication? If not, what are the factors that sustain political heterogeneity...
Article
This paper combines results from survey research and simulation to address questions regarding the nature and impact of political communication among citizens. While influential and long-standing theories predict that political disagreement will be a rare event among people who communicate on a frequent basis, the accumulating evidence points to a...
Article
This project explores agent-based models of the formation of individual opinions and collective judgments. The goal is to understand the effect of political communication on opinion formation and collective decision making.
Article
Several simulation models of public opinion are investigated in this paper. We begin with an implementation of Robert Axelrod's "culture model." After a discussion of the implications of that model, we then consider several variants. The central question is this: under what conditions will diversity be preserved? That is to say, when should we expe...
Book
Full-text available
The Swarm toolkit for agent-based modelling is discussed in three stages of increasing detail. The first part provides an introductory treatment and description of Swarm. The second part provides a deeper survey of the anatomy of a swarm program. The third part goes into significantly greater detail on some elements of programming in Swarm that use...
Article
Simulation research has made some notable contributions in political science. This article describes a variety of simulation projects and points out the strengths and weaknesses of simulation in contrast with other methods of research. The strength of simulation research is that it is naturally suited to modeling projects that include a large numbe...
Article
This paper explores the logic of a corporation's decision whether to create a political lobbying department to hire fee-for-service lobbyists. It does so by adapting the rent-seeking model of interest group behavior (Tullock 1980; Rowley, Tollison & Tullock 1988; Hillman & Riley 1989) in a sequential game. After the corporation decides whether or n...
Article
This paper presents results of simulation models of democratic government in voluntary organizations. The models explore the impact of changes in the institutions that control exit and entry into the organization as well as some basic parameters that determine the distribution of preferences. Results indicate the following. First, democratically go...
Article
Political parties receive a greater or lesser percent of seats than their percent of the vote in an election for a variety of reasons. District magnitude, the type of the electoral system, and strategic errors are three inherent features of an electoral system that affect seat bonuses. Malapportionment and turnout differentials are features specifi...
Article
This article explores the logic of political competition between interest groups. It is shown how a general model of group allocation of resources can be simplified to be equivalent with the well-known rent-seeking game model of government resource allocation. After the existence of equilibrium is investigated, comparative statics results illustrat...
Article
This essay presents a framework for the analysis of voting processes in interest group organizations. It explores the tension between majority rule and membership maintenance in a group. The major theoretical propositions are that myopic majority rule government can cause instability and a loss of members from the group. The risk of this instabilit...
Article
This chapter discusses the scope of mathematical modeling in political science. Mathematical models became popular in political science in the 1950s, when inferential statistics came into common usage. The 1950s and 1960s are referred to as the behavioral era, because most effort was focused on the detection of empirical patterns in voting behavior...
Article
It is a widely held belief that interest groups respond competitively to political challenges from other groups. This view is found not only in the traditional theory of interest groups, but also in the literature on policy typologies. Though it is not necessarily supposed that groups form in response to opposition, it is believed that when groups...
Article
This paper demonstrates the importance of foresight in organizational membership decisions. The analysis is directed toward union membership decisions, but the logic holds for other kinds of organizations which provide selective incentives on the basis of member seniority. Discussion proceeds along these lines. First, the importance of seniority an...
Article
This paper is about the theoretical implications of agent-based modeling exercises. Construction of an agent-based model challenges a social scientist to formalize many concepts and relationships that would have remained implicit or unrecognized. While formalizing these "unimportant" assumptions can be a nuisance, it can also have sub-stantial theo...
