Crime in New Democracies ∗

Crime rates have surged in nearly all new democracies. To explain this empirical regularity, we model the effects of political regimes on law enforcement and parametrize political regimes by their vulnerability to violent overthrow. It is assumed that democracies are less vulnerable than dictatorships. We first show that dictatorships generate more investment in “political protection” or secret...

Bivariate Qq-plots and Spider Web Plots

Abstract: QQ-plots are extremely useful in univariate data analysis. In this article, Koltchinskii (1997) and Chaudhuri’s (1996) definition of multivariate quantile is used to develop analogous plots for bivariate data. Bivariate qq-plots are exhibited for comparing a sample to a given population distribution (the bivariate normal), and for comparing two or more bivariate samples. The plots are...
