Olof Dahlbäck's book breaks new ground for the analysis of crime from a rationality perspective by presenting models and methods that go far beyond those with which researchers have hitherto been equipped. The book examines single crimes, individual criminality, and societal crime, and it discusses thoroughly the general decision theoretical presuppositions necessary for analyzing these various types of crime. An expected utility maximization model for a single discrete choice regarding the commission of a crime is the foundation of most of the analyses presented. A version of this model is developed that permits interpersonal comparisons, and this basic model is used when deriving more complex models of crime as well as when analyzing the potential for such derivations. The rigorous, powerful methods suggested provide considerable opportunities for improving research and for seeing old problems in a new light.

The concept of rationality used in this book. 2. Rational Decisions under Conditions of Risk. Focusing on individual's decisions under conditions of risk. The concept of utility. The von-Neumann-Morgenstern theory of maximization of expected utility. Maximization of expected 'riskless' utility. The basic model of the choice to commit or not to commit a crime. 3. Descriptive Validity of the Rationality Theories of Expected Utility Maximization. Introduction. Judgment mechanisms. Maximization of expected von-Neumann-Morgenstern utility. Prospect theory and the use of reference points. Some comments on research methods. What choices are the result of decisions? Why use the rational-choice approach? 4.
