Efeito do policiamento sobre a criminalidade: uma análise em painel para o municípios paulistas e estados brasileiros

This work had the aim of investigating the effect of policing over crime rates, analyzing both the municipalities of São Paulo as well the Brazilian states. The analysis of counties developed for four types of criminal practices classified as theft, burglary, robbery and vehicle theft and murders, while the second analysis of the Brazilian states was restricted to murders. The São Paulo counties crime data were extracted from the Bureau of Public Security of the State of São Paulo and the Brazilian state data has the Datasus/SIM as the main source. The model used is based on the economic theory of crime proposed by Becker (1968). The attempt of measuring the police effect over crime was carry on for 2 variables: the police force and the public security expenditure. Besides those variables, control variables were added to the regressions such as demographic and socio-economics, compiled from various sources. Models were estimated with fixed effects panel methodology, controlling for the simultaneity bias of the relationship between policing and crime in a two stages regression. The results, especially in the regressions for the Brazilian states, illustrate the positive bias of simultaneity between police and crime, once the firsts regressions, that did not control for this endogeneity, resulted in positive parameters, while all regressions in two stages resulted in negative coefficients for the police variable, which are significant when expenditure is used as public security measure. The São Paulo counties regressions, we found evidence that the existence of a municipality guard may have a reduction effect over thefts rate.

Impacto dos laudos de homicídio de latrocínio junto aos operadores do direito e às sentenças judiciais: o caso da perícia criminal do Instituto de Criminalística no âmbito do Distrito Federal

A presente pesquisa visa identificar o papel do Laudo de Perícia Criminal junto aos operadores do direito, bem como qual o grau de participação nas sentenças proferidas em âmbito judicial. Sabe-se que o Laudo de Perícia Criminal é um documento de cunho técnico-científico – produzido por perito criminal – com o objetivo de auxiliar à Justiça com seu conteúdo baseado no estudo de especialistas, sendo o Laudo de Perícia Criminal um dos meios de prova mais robustos utilizados pelo magistrado para proferir uma sentença judicial ou para uso dos jurados nos casos de crimes dolosos contra a vida. Parte do método de pesquisa foi qualitativo e, para a coleta de dados, utilizou-se de entrevista – mediante questionário – com operadores do direito (delegados de polícia, juízes de direito e promotores de justiça) que atuavam em processos de homicídio e/ou latrocínio e lotados nas cinco Regiões Administrativas que, em conjunto, abarcavam mais de 50% dos crimes dessas naturezas. Posteriormente passou-se à análise documental, onde foram verificados 172 (cento e setenta e dois) levantamentos de local e suas repercussões no âmbito judicial. Algumas conclusões em relação aos laudos foram apontadas: tais como sua intempestividade em alguns casos. Porém, foi possível abrir um novo olhar para o documento técnico que tanto auxilia a justiça criminal. Abordou-se, ainda, a falta de uma realimentação (feedback) de informações para os peritos criminais do Instituto de Criminalística, que acarreta problemas de ordem motivacional.

What causes violent crime?

This study uses a new data set of crime ratesfor a large sample of countriesfor the period 1970- 1994, based on information from the United Nations World Crime Surveys, to ana/yze the determinants ofnational homicide and robbery rates. A simple model of the incentives to commit crimes is proposed, which explicit/y considers possible causes of the persistence of crime over time (criminal inertia). Several econometric mode/s are estimated, attempting to capture the . determinonts of crime rates across countries and over time. The empirical mode/s are first run for cross-sections and then applie'd to panel data. The former focus on erplanatory variables that do not change markedly over time, while the panel data techniques consider both the eflect of the business cyc1e (i.e., GDP growth rate) on the crime rate and criminal inertia (accountedfor by the inclusion of the /agged crime rate as an explanatory variable). The panel data techniques a/so consider country-specific eflects, the joint endogeneity of some of the erplanatory variables, and lhe existence of some types of measurement e"ors aJjlicting the crime data. The results showthat increases in income inequality raise crime rates, dete"ence eflects are significant, crime tends to be counter-cyclical, and criminal inertia is significant even after controlling for other potential determinants of homicide and robbery rates.

Microinsurance: income risk, social security and the demand for private onsurance by low-income families

Insurance provision against uncertainties is present in several dimensions of peoples´s lives, such as the provisions related to, inter alia, unemployment, diseases, accidents, robbery and death. Microinsurance improves the ability of low-income individuals to cope with these risks. Brazil has a fairly developed financial system but still not geared towards the poor, especially in what concerns the insurance industry. The evaluation of the microinsurance effects on well-being, and the demand for different types of microinsurance require an analysis of the dynamics of the individual income process and an assessment of substitutes and complementary institutions that condition their respective financial behavior. The evaluation of the microinsurance effects on well-being, and the demand for different types of microinsurance require an analysis of the dynamics of the individual income process and an assessment of substitutes and complementary institutions that condition their respective financial behavior. The Brazilian government provides a relatively developed social security system considering other countries of similar income level which crowds-out the demand for insurance and savings. On the other hand, this same public infrastructure may help to foster microfinance products supply. The objective of this paper is to analyze the demand for different types of private insurance by the low-income population using microdata from a National Expenditure Survey (POF/IBGE). The final objective is to help to understand the trade-offs faced for the development of an emerging industry of microinsurance in Brazil.
