Crime and the fear of crime have a deep negative impact on personal and societal well-being. Several observed patterns regarding criminal behavior, however, remain inadequately understood. In this analysis, individual's perceptions (concerning their probabilities of punishment) and choices are determined endogenously, while incorporating the information available to them and how this information is generated within the economy. The resulting dynamic relationships are then studied to examine how criminality might evolve over time, why crime participation rates might differ among societal groups even when they face similar economic fundamentals, and how the features of the economy might affect these rates.

Empirical studies have overwhelmingly shown that a lower child mortality rate leads to lower fertility. Yet it has not been possible to satisfactorily analyze this relationship in even the simplest theoretical models. This paper attempts to bridge this gap between theory and the empirical literature. The paper also presents results on the effects of child mortality changes on parental welfare. The analysis captures the dynamic stochastic feature of fertility choice, subsumes other endogeneous choices (e.g., the quality of the children), and treats the number of children as a discrete variable (this added realism is important for the analysis).
