There is also evidence that the IGESP is associated with improved police response … represented by the program may constitute a first-order factor in a successful policy for fighting crime. …

The paper revisits the local determinants of crime using a spatial model distinguishing between resident and non … crime. Also the socio-economic background in terms of unemployment, poverty, and inequality proves significant for both … property and violent crime. Whereas local inequality only shows an effect on crime committed by resident offenders, crime …

This paper analyzes the identifying power of weak convexity assumptions in treatment effect models with endogenous selection. The counterfactual distributions are constrained either in terms of the response function, or conditional on the realized treatment, and sharp bounds on the potential...

This paper studies single equation instrumental variable models of ordered choice in which explanatory variables may be endogenous. The models are weakly restrictive, leaving unspecified the mechanism that generates endogenous variables. These incomplete models are set, not point, identifying...

Single equation instrumental variable models for discrete outcomes are shown to be set not point identifying for the structural functions that deliver the values of the discrete outcome. Identified sets are derived for a general nonparametric model and sharp set identification is demonstrated....

We solve a class of identification problems for nonparametric and semiparametric models when the endogenous covariate is discrete with unbounded support. Then we proceed with an approach that resolves a polynomial basis problem for the above class of discrete distributions, and for the...

This paper argues that terrorism, beyond its immediate impact on innocent victims, also raises the costs of crime, and … therefore, imposes a negative externality on potential criminals. Terrorism raises the costs of crime through two channels: (i …) by increasing the presence and activity of the police force, and (ii) causing more people to stay at home rather than …
