Risk,power and crime prevention

This paper addresses the development of post-disciplinary ‘actuarial’ or risk-based technologies of power. Arguing against models which focus on icreased efficiency as an evolutionary criterion for emerging technologies of power, it suggests that such technologies' place and form are largely dtermined by the nature and fortunes of political programs with which they are aligned. Thus the rise of neo-conservatism and related programs have extensively modified and curtailed programs based on risk models, and expanded those based on punishment and discipline. The paper examines the nature of situational crime prevention in the light of these ideas, and moves on to consider certain broader theoretical implications.     

Return migration,crime, and electoral engagement in Mexico

Since 2006, the Great Recession and tighter migration policies in the U.S. have increased the rates of return migration to Mexico. Scholars debate whether high rates of return motivate greater electoral engagement via the democratic norms returnees may bring back with them. An alternative account holds that returnees are seen as dissimilar by their non-migrant co-nationals, causing returnees to disengage from politics. We contribute to this debate using municipal data on voter turnout and on rates of return migration for the case of Mexico from 2000 to 2010. Relying on an instrumental strategy that exploits migrants’ exposure to changes in unemployment rates as an exogenous predictor for return, we find robust evidence that high rates of return result in less electoral participation in presidential and local elections. Besides, electoral disengagement seems to be intensified by the presence of criminal violence, which surged during our period of analysis. Return migration may have a positive impact on other modes of political participation; but at least when it comes to voting, our research aligns with the pessimistic camp of the debate in that return migration increases electoral apathy.

The crime effect of refugees

We analyze the impact on crime of millions of refugees who entered and stayed in Turkey as a result of the civil war in Syria. Using a novel administrative data source on the flow of offense records to prosecutors’ offices in 81 provinces of the country each year, and utilizing the staggered movement of refugees across provinces over time, we estimate instrumental variables models that address potential endogeneity of the number of refugees and their location and find that an increase in the number of refugees leads to more crime. We estimate that the influx of refugees between 2012 and 2016 generated additional 75,000 to 150,000 crimes per year, although it is not possible to identify the distribution of these crimes between refugees and natives. Additional analyses reveal that a low-educated native population has a separate, but smaller, effect on crime. Our results underline the need to quickly strengthen the social safety systems, to take actions to dampen the impact on the labor market, and to provide support to the criminal justice system for mitigating the repercussions of massive influx of individuals into a country, and to counter the social and political backlash that typically emerges in the wake of such large-scale population movements.

Protest and property crime: political use of police resources and the deterrence of crime

This article investigates the claim that the political use of police resources promotes crime. Using a panel of South Korean metropolitan areas, we show that (1) the reallocation of police resources toward the control of political protests reduces arrest rates for crime and (2) the resulting reduction in criminal arrests significantly increases the incidence of crime. Overall, the impact of the reallocation of police resources works mainly through tradeoffs with arrest rates. Our findings imply that it is not the size of the police per se, but the allocation of police resources toward crime control that deters crime.     

A cure for crime: Can mental health treatment diversion reduce crime among youth?

Youth crime is a serious social problem, as is the high proportion of young offenders in the juvenile justice system who have mental disorders. A recent policy innovation applies the theory of therapeutic jurisprudence and diverts youth with mental disorders to treatment in lieu of further court processing. The expansion of mental health diversion programs reflects an increasingly popular view that there is a causal relationship between youth mental disorders and crime. Policymakers who share this view place greater emphasis on rehabilitation and treatment as a way to reduce crime, rather than on stricter punishment. This paper considers the policy issues around youth mental health diversion programs. In addition, it evaluates the effect of a mental health diversion program for youth that was implemented in Texas. The paper finds that mental health diversion can be used effectively to delay or prevent youth recidivism.
