In the last years, several countries implemented policy interventions to entitle urban squatters, encouraged by the results of studies showing large welfare gains from entitlement. We study a natural experiment in the allocation of land titles to very poor families in a suburban area of Buenos Aires, Argentina. Although previous studies on this experiment have found important effects of titling on investment, household structure, educational achievement, and child health, in this article we document that a large fraction of households that went through a situation at which formalization was challenged (death, divorce, sale/purchase), ended up being de-regularized. The legal costs of remaining formal seem too high relative to the value of these parcels and the income of their inhabitants.

We study the re-arrest rates for two groups: individuals formerly in prison and individuals formerly under electronic monitoring (EM). We find that the recidivism rate of former prisoners is 22% while that for those 'treated' with electronic monitoring is 13% (40% lower). We convince ourselves that the estimates are causal using peculiarities of the Argentine setting. For example, we have almost as much information as the judges have when deciding on the allocation of EM; the program is rationed to only some offenders; and some institutional features (such as bad prison conditions) convert ideological differences across judges (to which detainees are randomly matched) into very large differences in the allocation of electronic monitoring.

We study desensitization to crime in a lab experiment by showing footage of criminal acts to a group of subjects, some of whom have been previously victimized. We measure biological markers of stress and behavioral indices of cognitive control before and after treated participants watch a series of real, crime-related videos (while the control group watches non-crime-related videos). Not previously victimized participants exposed to the treatment video show significant changes in cortisol level, heart rate, and measures of cognitive control. Instead, previously victimized individuals who are exposed to the treatment video show biological markers and cognitive performance comparable to those measured in individuals exposed to the control video. These results suggest a phenomenon of desensitization or habituation of victims to crime exposure.

Large numbers of people in urbanizing regions in the developing world live and work in unplanned settlements that grow through incremental processes of squatting and self-building. Slums: How Informal Real Estate Markets Work shows that unauthorized settlements in rapidly growing cities are not divorced from market forces; rather, they must be understood as complex environments where state policies and market actors still do play a role. In this volume, contributors examine how the form and function of informal real estate markets are shaped by legal systems governing property rights, by national and local policy, and by historical and geographic particularities of specific neighborhoods. Their essays provide detailed portraits of individuals and community organizations, revealing in granular detail the working of informal real estate markets, and they review programs that have been implemented in unconventional settlements to provide lessons about the effectiveness and implementation challenges of different approaches. Chapters explore the relationships between informality, state policies, and market forces from a range of disciplinary perspectives and on different scales, from an analysis of the relationship between regulations and housing in six hundred developing world cities to an ethnographic account of the buying and selling of houses in Rio de Janeiro's favelas. While many of the book's contributors focus on the emerging economies of India and Brazil, the conclusions drawn illustrate dynamics relevant to developing countries throughout the Global South. The diversity of perspectives combines to create a rich understanding of an important, complex, and understudied topic.
