The effect of Ponzi schemes on crime: Evidence from the colombian case

This paper estimates the impact of a massive negative income shock led by the simultaneous crash down of several Ponzi schemes (also known as financial ``pyramids"") in Colombia on crime rates at the municipal level. Using novel data on the spatial incidence of the latest wave of Colombian pyramids and their crash down date, I estimate difference-in-differences models with both monthly and yearly frequency. I find that the negative income shock of the pyramids" crash down differentially exacerbates crime in affected municipalities compared to those with no presence of Ponzi schemes. This is true for minor offenses like commercial theft or residential burglary, but not for major crimes as murder or terrorism.

The swindle crime: a necessary normative construction of its elements

The present work exposes a review about the performance of the “traditional” thesis(Naturalistic) of the swindle crime in front of the needs of the present’s Political Policy.For this system, the various frauds’ elements require a causal relationship. Today itmight be wondered whether this solution is desirable, i.e. whether respond efficientlyto the problematic assumptions that the contemporary business practices raises.

Incidencia de la política de Seguridad Democrática en la inversión y migración venezolana en el sector de hidrocarburos en Colombia. Periodo 2002-2010.

El presente trabajo busca analizar los factores que llevaron a que se produjera una importante dinámica migratoria de venezolanos que llegaron a Colombia a invertir o a trabajar en el sector de hidrocarburos. Específicamente se busca encontrar la incidencia de la política de Seguridad Democrática en este fenómeno tomando como periodo de estudio el gobierno de Álvaro Uribe Vélez, es decir, de 2002 a 2010. Se examina la percepción de seguridad en Colombia vista por los venezolanos y por los colombianos y los diferentes factores que contribuyeron al “boom” petrolero en este país. El resultado de las investigaciones de este estudio de caso permite establecer que la Seguridad Democrática si fue un factor incidente en las dinámicas migratorias pero que se articula junto con otros hechos específicos para que se haya dado de la manera que se dio y que en este texto se expone.

La captura del estado vista desde los procesos de formulación e implementación de la política pública agro ingreso seguro. Periodo 2007-2009

RESUMEN En esta monografía el interés es comprender la dimensión de la captura del estado, su complejidad y cómo ha penetrado en la cultura política institucional de nuestro país; así mismo, el análisis permite entender el grado de influencia de los grupos de poder para lograr leyes y regulaciones a favor suyo en detrimento del interés general. Este trabajo aborda dicho fenómeno en los procesos de formulación e implementación de la política pública de Agro Ingreso Seguro – AIS– y explica consecuencias y efectos de la captura del Estado en su gobernabilidad y eficacia social. Para ello se desarrolló una investigación de tipo documental que permitió identificar el grado de legitimación de los propósitos de la política pública poniendo en perspectiva la intervención de agentes capturadores en el proceso de implementación de la política Agro Ingreso Seguro.

Neighborhood characteristics and the spatial concentration of crime: Evidence for Bogotá

Using a unique neighborhood crime dataset for Bogotá in 2011, this study uses a spatial econometric approach and examines the role of socioeconomic and agglomeration variables in explaining the variance of crime. It uses two different types of crime, violent crime represented in homicides and property crime represented in residential burglaries. These two types of crime are then measured in non-standard crime statistics that are created as the area incidence for each crime in the neighborhood. The existence of crime hotspots in Bogotá has been shown in most of the literature, and using these non-standard crime statistics at this neighborhood level some hotspots arise again, thus validating the use of a spatial approach for these new crime statistics. The final specification includes socioeconomic, agglomeration, land-use and visual aspect variables that are then included in a SARAR model an estimated by the procedure devised by Kelejian and Prucha (2009). The resulting coefficients and marginal effects show the relevance of these crime hotspots which is similar with most previous studies. However, socioeconomic variables are significant and show the importance of age, and education. Agglomeration variables are significant and thus more densely populated areas are correlated with more crime. Interestingly, both types of crimes do not have the same significant covariates. Education and young male population have a different sign for homicide and residential burglaries. Inequality matters for homicides while higher real estate valuation matters for residential burglaries. Finally, density impacts positively both crimes.

Territorialización de la inseguridad ciudadana en Bogotá: La Calle del Bronx

La tesis devela la connotación sistemática y multicausal de lo que a través de la investigación se denomina como "Procesos de Territorialización de la Inseguridad Ciudadana". Mediante un estudio de caso, se pone en evidencia la apropiación y captura sostenida en el tiempo de fenómenos como la inseguridad y la criminalidad, sobre determinadas zonas o barrios urbanos que por sus características socioeconómicas, políticas, geográficas, culturales, laborales y de mercado de quienes los habitan o frecuentan, se consideran como sectores "críticos y/o vulnerables".

The crime kuznets curve

We document the existence of a Crime Kuznets Curve in US states since the 1970s. As income levels have risen, crime has followed an inverted U-shaped pattern, first increasing and then dropping. The Crime Kuznets Curve is not explained by income inequality. In fact, we show that during the sample period inequality has risen monotonically with income, ruling out the traditional Kuznets Curve. Our finding is robust to adding a large set of controls that are used in the literature to explain the incidence of crime, as well as to controlling for state and year fixed effects. The Curve is also revealed in nonparametric specifications. The Crime Kuznets Curve exists for property crime and for some categories of violent crime.

Economic shocks and crime: evidence from the crash of ponzi schemes

In November 2008, Colombian authorities dismantled a network of Ponzi schemes, making hundreds of thousands of investors lose tens of millions of dollars throughout the country. Using original data on the geographical incidence of the Ponzi schemes, this paper estimates the impact of their break down on crime. We find that the crash of Ponzi schemes differentially exacerbated crime in affected districts. Confirming the intuition of the standard economic model of crime, this effect is only present in places with relatively weak judicial and law enforcement institutions, and with little access to consumption smoothing mechanisms such as microcredit. In addition, we show that, with the exception of economically-motivated felonies such as robbery, violent crime is not affected by the negative shock.
