The Policy Research Working Paper Series disseminates the findings of work in progress to encourage the exchange of ideas about development issues. An objective of the series is to get the findings out quickly, even if the presentations are less than fully polished. The papers carry the names of the authors and should be cited accordingly. The findings, interpretations, and conclusions expressed in this paper are entirely those of the authors. They do not necessarily represent the views of the International Bank for Reconstruction and Development/World Bank and its affiliated organizations, or those of the Executive Directors of the World Bank or the governments they represent.

Este trabalho avalia os efeitos da Lista de Municípios Prioritários, que indica os principais alvos de fiscalização da autoridade ambiental, sobre o desmatamento dos municípios na vizinhança dos listados. Argumenta-se que ter um vizinho listado causa uma variação exógena na presença das autoridades ambientais, e um estimador de diferença-em-diferenças é usado para determinar o impacto dessa presença sobre o desmatamento. Uma contribuição deste trabalho é acrescentar uma versão espacial do estimador para corrigir a dependência espacial na variável dependente. Nossos resultados mostram que o efeito líquido do tratamento é reduzir o desmatamento entre 19% e 23%, e que esse efeito enfraquece à medida que a distância até o município prioritário aumenta.

No abstract

Data collection and cleaning workflows implement highly repetitive but extremely important processes. In this article, we introduce iefieldkit, a package developed to standardize and simplify best practices for high-quality primary data collection across the World Bank’s Development Research Group Impact Evaluations department. iefieldkit automates error-checking for electronic Open Data Kit-based survey modules such as those implemented in SurveyCTO; duplicate checking and resolution; data cleaning, including renaming, labeling, recoding, and survey harmonization; and codebook creation.
