Padronização dos suprimentos utilizados nas maletas de local de crime dos institutos de criminalística do Brasil

Nos início da década de 90 teve início um movimento em todo Brasil, impulsionado por uma carta de intenções da ONU, que sugeria a desvinculação da Perícia Criminal da Instituição Polícia Civil. Após este movimento, verificou-se uma grande diversidade de estruturas que originaram as Instituições Periciais, tanto operacionalmente como administrativamente, chancelando um status quo de completo empirismo em todos os setores periciais. Buscou-se neste trabalho, iniciar uma análise da possibilidade de padronização dos materiais utilizados na coleta de impressões digitais latentes contidos na maleta de local de crime doada pela SENASP a todos os Institutos de Criminalística do Brasil. Na tentativa de alcançar a maior representatividade possível dentre os Institutos de Criminalística brasileiros, utilizou-se um questionário eletrônico direcionado ao Fórum Nacional de Peritos Criminais (FNPC), onde se obteve amostra de quase todos os estados da federação. No resultado alcançado qualitativamente, a marca comercial SIRCHIE demonstrou ter preferência considerável entre a classe Pericial.

Three essays on local demand for public services

Local provision of public services has the positive effect of increasing the efficiency because each locality has its idiosyncrasies that determine a particular demand for public services. This dissertation addresses different aspects of the local demand for public goods and services and their relationship with political incentives. The text is divided in three essays. The first essay aims to test the existence of yardstick competition in education spending using panel data from Brazilian municipalities. The essay estimates two-regime spatial Durbin models with time and spatial fixed effects using maximum likelihood, where the regimes represent different electoral and educational accountability institutional settings. First, it is investigated whether the lame duck incumbents tend to engage in less strategic interaction as a result of the impossibility of reelection, which lowers the incentives for them to signal their type (good or bad) to the voters by mimicking their neighbors’ expenditures. Additionally, it is evaluated whether the lack of electorate support faced by the minority governments causes the incumbents to mimic the neighbors’ spending to a greater extent to increase their odds of reelection. Next, the essay estimates the effects of the institutional change introduced by the disclosure on April 2007 of the Basic Education Development Index (known as IDEB) and its goals on the strategic interaction at the municipality level. This institutional change potentially increased the incentives for incumbents to follow the national best practices in an attempt to signal their type to voters, thus reducing the importance of local information spillover. The same model is also tested using school inputs that are believed to improve students’ performance in place of education spending. The results show evidence for yardstick competition in education spending. Spatial auto-correlation is lower among the lame ducks and higher among the incumbents with minority support (a smaller vote margin). In addition, the institutional change introduced by the IDEB reduced the spatial interaction in education spending and input-setting, thus diminishing the importance of local information spillover. The second essay investigates the role played by the geographic distance between the poor and non-poor in the local demand for income redistribution. In particular, the study provides an empirical test of the geographically limited altruism model proposed in Pauly (1973), incorporating the possibility of participation costs associated with the provision of transfers (Van de Wale, 1998). First, the discussion is motivated by allowing for an “iceberg cost” of participation in the programs for the poor individuals in Pauly’s original model. Next, using data from the 2000 Brazilian Census and a panel of municipalities based on the National Household Sample Survey (PNAD) from 2001 to 2007, all the distance-related explanatory variables indicate that an increased proximity between poor and non-poor is associated with better targeting of the programs (demand for redistribution). For instance, a 1-hour increase in the time spent commuting by the poor reduces the targeting by 3.158 percentage points. This result is similar to that of Ashworth, Heyndels and Smolders (2002) but is definitely not due to the program leakages. To empirically disentangle participation costs and spatially restricted altruism effects, an additional test is conducted using unique panel data based on the 2004 and 2006 PNAD, which assess the number of benefits and the average benefit value received by beneficiaries. The estimates suggest that both cost and altruism play important roles in targeting determination in Brazil, and thus, in the determination of the demand for redistribution. Lastly, the results indicate that ‘size matters’; i.e., the budget for redistribution has a positive impact on targeting. The third essay aims to empirically test the validity of the median voter model for the Brazilian case. Information on municipalities are obtained from the Population Census and the Brazilian Supreme Electoral Court for the year 2000. First, the median voter demand for local public services is estimated. The bundles of services offered by reelection candidates are identified as the expenditures realized during incumbents’ first term in office. The assumption of perfect information of candidates concerning the median demand is relaxed and a weaker hypothesis, of rational expectation, is imposed. Thus, incumbents make mistakes about the median demand that are referred to as misperception errors. Thus, at a given point in time, incumbents can provide a bundle (given by the amount of expenditures per capita) that differs from median voter’s demand for public services by a multiplicative error term, which is included in the residuals of the demand equation. Next, it is estimated the impact of the module of this misperception error on the electoral performance of incumbents using a selection models. The result suggests that the median voter model is valid for the case of Brazilian municipalities.

Proposta metodológica de perícia contábil para o crime de apropriação indébita previdenciária

No decorrer dos últimos anos vêm ocorrendo uma demanda crescente da utilização de serviços periciais nos mais diversos campos. No campo contábil, especificamente no contexto dos crimes previdenciários, a gama de serviços periciais contábeis prestados às lides forenses aumenta a cada dia que passa. Este estudo trata da perícia contábil como meio de prova para materialização do crime de apropriação indébita previdenciária. O desenvolvimento do tema foi efetuado a partir da pesquisa efetuada por Oliveira (2012), que comprovou a relação existente entre tipo penal e a prova pericial contábil, bem como de interpretações da legislação pertinente, no caso, a Constituição da República Federativa do Brasil, Código Penal, Código do Processo Penal e Normas Brasileiras de Contabilidade aplicáveis à perícia. Esta dissertação teve por objetivo a proposição de metodologia para realização de exames periciais que visam a comprovação do cometimento do crime de apropriação indébita previdenciária. A pesquisa empírica foi realizada num total de 79 laudos contábeis emitidos pela criminalística da Polícia Federal no período de junho de 2006 a junho de 2011, envolvendo os exames periciais sobre o crime de apropriação indébita previdenciária, para verificar a natureza das provas utilizadas nestes exames, e, por conseguinte, reunir o conjunto probatório utilizado. Como resultado da pesquisa realizada, foi apresentada uma metodologia para realização de exames periciais contendo o conjunto probatório considerado essencial para a materialização do crime de apropriação indébita previdenciária.

Do police reduce crime? Estimates using the allocation of police forces after a terrorist attack

An important challenge in the crime literature is to isolate causal effects of police on crime. Following a terrorist attack on the main Jewish center in the city of Buenos Aires, Argentina, in July 1994, all Jewish institutions (including schools, synagogues, and clubs) were given 24-hour police protection. Thus, this hideous event induced a geographical allocation of police forces that can be presumed to be exogenous in a crime regression. Using data on the location of car thefts before and after the terrorist attack, we find a large deterrent effect of observable police presence on crime. The effect is local, with little or no appreciable impact outside the narrow area in which the police are deployed.

Lighting and violent crimes: evaluating the effect of an electrification policy in rural Brazil on violent crime reduction

This paper estimates the effect of lighting on violent crime reduction. We explore an electrification program (LUZ PARA TODOS or Light for All - LPT) adopted by the federal government to expand electrification to rural areas in all Brazilian municipalities in the 2000s as an exogenous source of variation in electrification expansion. Our instrumental variable results show a reduction in homicide rates (approximately five homicides per 100,000 inhabitants) on rural roads/urban streets when a municipality moved from no access to full coverage of electricity between 2000 and 2010. These findings are even more significant in the northern and northeastern regions of Brazil, where rates of electrification are lower than those of the rest of the country and, thus, where the program is concentrated. In the north (northeast), the number of violent deaths on the streets per 100,000 inhabitants decreased by 48.12 (13.43). This moved a municipality at the 99th percentile (75th) to the median (zero) of the crime distribution of municipalities. Finally, we do not find effects on violent deaths in households and at other locations. Because we use an IV strategy by exploring the LPT program eligibility criteria, we can interpret the results as the estimated impact of the program on those experiencing an increase in electricity coverage due to their program eligibility. Thus, the results represent local average treatment effects of lighting on homicides.
