Drug battles and school achievement: evidence from Rio de Janeiro's favelas

This paper examines the effects of armed conflicts between drug gangs in Rio de Janeiro's favelas on student achievement. We explore variation in violence that occurs across time and space when gangs battle over territories. Within-school estimates indicate that students from schools exposed to violence score less in math exams. The effect of violence increases with conflict intensity, duration, and proximity to exam dates; and decreases with the distance between the school and the conflict location. Finally, we find that school supply is an important mechanism driving the achievement results; armed conflicts are significantly associated with higher teacher absenteeism, principal turnover, and temporary school closings.

A model of rural conflict : violence and land reform policy in Brazil

In the past ten years the struggle for land in Brazil has taken the shape of invasions of private land by welI organized groups of land less squatters. It is argued in this paper that these invasions and the resulting contlicts are a direct response to the land reform program which has been adopted by the govemment since 1985. which is based on the expropriation of farms and the creation of settlement projects. The set of formal and informal institutions which compromise the land reform program are used as the background for a game-theory model of rural contlicts. T estable implications are derived trom this model with particular emphasis on the etfect of policy variables on violence. These are then tested with panel data at state levei from 1988 to 1995. - It is shown that govemment policy which has the intent of reducing the amount of violence has the opposite etfect of leading to more incentives for contlicts.

O crime de drogas e a violência em São Paulo: uma análise a partir da Lei de Drogas

O objetivo desta pesquisa é estudar o efeito da Lei nº 11.343/06 (Lei de Drogas) sobre o crime de tráfico e porte de drogas e a relação entre crimes de drogas e outros crimes. Para isso, são exploradas as variações da Lei de Drogas, através de análises de regressões com descontinuidade e com variável instrumental, além de estimações com dados em painel, em busca de um efeito causal entre drogas e violência. Como resultados, a Lei de Drogas parece não ter efeito negativo significativo sobre crimes de drogas. Por outro lado, crimes de drogas apresentam uma associação negativa sobre crimes de furto e uma relação positiva com crimes de formação de quadrilha. Para cada redução de 100 crimes de drogas (por mil habitantes) associa-se um aumento de 3,6 crimes de furto (por mil habitantes) e uma diminuição de 27 crimes de formação de quadrilha (por mil habitantes). Não são encontrados efeitos robustos sobre roubos, homicídios, latrocínios, estupros, crimes de lesão corporal e porte de arma de fogo.

Domestic violence in Brazil: social problems and legislative interventions

Recent statistical data confirms that domestic violence is a structural problem of exceptional gravity. We analyze the frequent legislative changes in Brazil since 2000 as a result of social pressure for protection of abused women. Only the Law 11.340 of 2006 was well received by lawyers, judges and the public opinion. We present the innovations and peculiarities of this statute and the allegations on unconstitutionality. We discuss cases of judicial review of this law and reject the arguments of unconstitutionality. That notwithstanding, we argue that penalization decisions is the wrong way from a criminological point of view because they do not take into consideration the desires and needs of the victims.
