Although the issue of offender decision-making pervades almost every discussion of crime and law enforcement, only a few comprehensive texts cover and integrate information about the role of decision-making in crime. The Oxford Handbook of Offender Decision Making provide high-quality reviews of the main paradigms in offender decision-making, such as rational choice theory and dual-process theory. It contains up-to-date reviews of empirical research on decision-making in a wide range of decision types including not only criminal initiation and desistance, but also choice of locations, times, targets, victims, methods as well as large variety crimes including homicide, robbery, domestic violence, burglary, street crime, sexual crimes, and cybercrime. Lastly, it provides in-depth treatments of the major methods used to study offender decision-making, including experiments, observation studies, surveys, offender interviews, and simulations. Comprehensive and authoritative, the Handbook will quickly become the primary source of theoretical, methodological, and empirical knowledge about decision-making as it relates to criminal behavior.

Agent-Based Modelling for Criminological Theory Testing and Development addresses the question whether and how we can use simulation methods in order to test criminological theories, and if they fail to be corroborated, how we can use simulation to mend and further develop theories. It is by no means immediately obvious how results being observed in an artificial environment have any relevance for what is going on in the real world. By using the concept of a "stylized fact," the contributors bridge the gap between artificial and real world. With backgrounds in criminology or artificial intelligence (AI), these contributors present agent-based model studies that test aspects of various theories, including crime pattern theory, guardianship in action theory, near repeat theory, routine activity theory, and general deterrence theory. All six simulation models presented have been specially developed for the book. Contributors have specified the theory, identified stylized facts, developed an agent-based simulation model, let it run, and interpreted whether the chosen stylized fact is occurring in their model, and what we should conclude from congruence or incongruence between simulation and expectations based on the theory under scrutiny. The final chapter discusses what can be learnt from these six enterprises.The book will be of great interest to scholars of criminology (in particular computational criminologists and theoretical criminologists) and AI (with an emphasis on AI for generative social processes), and more widely researchers in social science in general. It will also be valuable for master's courses in quantitative criminology.

This book brings together an influential group of academics and researchers to review key areas of research, theory and methodology within criminology and criminal justice, and to identify the most important new challenges facing the discipline. The contributors focus on the three central themes of punishment and criminal justice, location and mobility, and perpetrators and criminal careers, on which much cutting edge research within criminology has been taking place. A particular strength of the book is its multidisciplinary and international approach, with contributors drawn from Europe, the UK and the United States.

Research and theorizing on criminal decision making has not kept pace with recent developments in other fields of human decision making. Whereas criminal decision making theory is still largely dominated by cognitive approaches such as rational choice-based models, psychologists, behavioral economists and neuroscientists have found affect (i.e., emotions, moods) and visceral factors such as sexual arousal and drug craving, to play a fundamental role in human decision processes.This book examines alternative approaches to incorporating affect into criminal decision making and testing its influence on such decisions. In so doing it generalizes extant cognitive theories of criminal decision making by incorporating affect into the decision process. In two conceptual and ten empirical chapters it is carefully argued how affect influences criminal decisions alongside rational and cognitive considerations. The empirical studies use a wide variety of methods ranging from interviews and observations to experimental approaches and questionnaires, and treat crimes as diverse as street robbery, pilfering, and sex offences. It will be of interest to criminologists, social psychologists, judgment and decision making researchers, behavioral economists and sociologists alike.

The aim of this book, first published in 1991, is not to examine the moral or economic rights and wrongs of the issue, but to introduce a fresh way of exploring this old but growing problem. Research into tax evasion has been bedevilled with measurement problems: the hidden economy has been well named. The key is to design experimental situations that engage the same psychological processes as their real-world counterparts. This has been achieved by embedding the declaration of taxes in simulated business games. A feature of the research is that it is cross-national (carried out in the Netherlands and the UK), which also enhances ecological validity. This work will be of particular interest to applied social psychologists, tax researchers and experimental economists.
