Abstract Brazilian banks commonly use linear regression to appraise real estate: they regress price on features like area, location, etc, and use the resulting model to estimate the market value of the target property. But Brazilian banks do not test the predictive performance of those models, which for all we know are no better than random guesses. That introduces huge inefficiencies in the real estate market. Here we propose a machine learning approach to the problem. We use real estate data scraped from 15 thousand online listings and use it to fit a boosted trees model. The resulting model has a median absolute error of 8.16%. We provide all data and source code.

Abstract In this paper we evaluate the impact of grade span configuration on student outcomes. We build a model which shows that the more homogeneous the cohort of students the higher the share of them which achieves the minimum level of academic performance required in an exam. We then test this theoretical finding by comparing performances of 5th-grade students of elementary schools (1st to 5th grade) and those of elementary-middle schools (1st to 9th grade) in Brazil. PSM and PSM with Diff-in-Diff methodologies are used to control possible biases. We find that elementary schools present better results in Portuguese language and mathematics standardized score tests, higher passing rates and lower dropout rates than elementary-middle schools, which corroborates the theoretical results. The robustness of estimates is checked through several tests and alternative specifications. Finally, we found evidence that the main mechanisms behind our results are related to alternative pedagogical practices and school management policies.

Resumo O presente texto visa avaliar o efeito causado pelo programa das Unidades de Policia Pacificadora (UPP) na taxa de homicidios no municipio do Rio de Janeiro. Foi utilizado o modelo de controle sintetico para calcular esse efeito. O metodo permitiu criar um Rio de Janeiro sintetico, ou seja, como seria o Rio de Janeiro caso o programa das UPP nao tivesse sido implementado o que permitiu avaliar os resultados do programa. A implantacao das UPP reduziu os homicidios na cidade do Rio de Janeiro no periodo de analise (1999–2016).

Resumo Este artigo utiliza a metodologia de ponderacao bayesiana de modelos para acomodar a incerteza sobre os potenciais determinantes do crescimento economico nos estados brasileiros. O procedimento leva em conta a possivel endogeneidade de algumas variaveis e calcula uma media ponderada dos coeficientes de inumeros modelos, com pesos dados pela probabilidade posterior de cada modelo. Os resultados, baseados em dados em painel de 1992 a 2016 e em diversos potenciais determinantes do crescimento economico, sugerem que PIB inicial, qualidade de vida, educacao, investimento privado, composicao setorial e despesas em saude publica sao determinantes robustos do crescimento nos estados brasileiros.

Resumo O artigo tem por objetivo analisar a relacao entre os homicidios por armas de fogo e sua ligacao com a posse de armas de fogo legais nas cinco regioes brasileiras. Para isso, utilizou-se da metodologia de dados em painel com estimacao por efeitos fixos e System-GMM. Os resultados mostraram que homicidios tem relacao direta com armas legais. Porem, nas regioes Sul e Nordeste observa-se uma relacao inversa, ou seja, na regiao Sul o aumento de arma legal nao representou um aumento de homicidios e na regiao Nordeste o aumento de homicidios nao esta relacionado a aquisicao de armas legais.

Abstract This paper estimates the payroll tax exemption effects by two alternative approaches. First, a Quasi-experiment which takes into account the fact that firms under the tax regime called Simples already do not pay payroll taxes to define such group of firms as control. The other approach was a structural model which considers payroll tax as a source of market imperfection, whose effects can be estimated from production function coefficients. Results suggest that Quasi-Experimental methodology overestimated policy effects and the conclusion is that this policy had reduced effects.
