This year’s Report on Economics and Development (RED) proposes an approach for the analysis of insecurity in which crime results from decisions made by individuals in a particular situation. While it is true that beliefs, perceptions, self-control, and other personality traits (in turn shaped by family experiences, education level, job opportunities, and other experiences throughout the life cycle) can tip an individual into crime, his physical and social environment, the incentives provided by illegal markets (e.g., drugs), and the credibility and efficiency of the criminal justice system are also important.
