Abstract |
Dr Lott's econometric suggestions are problematic. It is well known that arrest rates have a spurious negative correlation with the crime rate, since the latter constitutes the denominator of the former.1 Introducing an "independent" variable that is co-determined with the dependent variable will generally bias all coefficient estimates. |
