Participation in Illegitimate Activities: A Theoretical and Empirical Investigation

Open access
Ehrlich, Isaac·1973·Journal of Political Economy

Abstract

A theory of participation in illegitimate activities is developed and tested against data on variations in index crimes across states in the United States. Theorems and behavioral implications are derived using the state preference approach to behavior under uncertainty. The investigation deals directly with the interaction between offense and defense: crime and collective law enforcement. It indicates the existence of a deterrent effect of law-enforcement activity on all crimes and a strong positive correlation between income inequality and crimes against property. The empirical results also provide some tentative estimates of the effectiveness of law enforcement in reducing crime and the resulting social losses.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
