Empirical studies have shown, paradoxically, that increasing the probability of apprehension can correlate with an increase in the total number of criminal actions. To examine this phenomenon, we develop a dynamic model of “personal rules” in which forgetfulness and hyperbolic discounting together can cause a potential criminal to commit more crimes as the probability of apprehension increases. At the time of the future decision, he may commit a crime due to hyperbolic discounting, even if it is not profitable. Hence, he may choose not to commit a crime today as a commitment device to abstain from crime in the future. However, increased prosecution can limit the effectiveness of the commitment device.
