Our paper uses daily data of thirteen Brazilian market indicators from February 2007 to July 2015, employing an event study approach together with diverse linear and nonlinear tests to evaluate QE’s influence in the returns of these indicators. Results suggest that, regardless of the tests performed, there are strong evidences that QE had an influence in the assets return. However, the first phase had a greater effect on the returns compared to the rest.","PeriodicalId":35050,"journal":{"name":"Economia Aplicada","volume":"24 1","pages":"435-460"},"PeriodicalIF":0.0,"publicationDate":"2020-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48426156","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Through these measures, it was found that institutionally efficient countries are the least corrupt and corruption negatively impacts the efficiency of institutions. Therefore, considering the relevance of institutions for the growth and development of countries, the importance of formulating public policies that fight corruption is emphasized, because in this way, institutions will become more efficient and the countries economically more prosperous.","PeriodicalId":35050,"journal":{"name":"Economia Aplicada","volume":"24 1","pages":"461-486"},"PeriodicalIF":0.0,"publicationDate":"2020-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44825283","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Hence, in order to improve the assertiveness of public policies, minimize the divergence between actions proposed by different studies and contribute to mitigate those issues, this paper seeks to understand the relative impacts of the proposed policies as well as their efficiency. Thus, this paper evaluates the Brazilian Rental Housing Program (RHP) using a regression discontinuity design (RDD) model, a strategy that is strengthened by the performance of robustness tests. As a result, we verified that RHP was able to reduce deaths from sanitation-related diseases by up to 11% and that this effect increases over time.","PeriodicalId":35050,"journal":{"name":"Economia Aplicada","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2020-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46848904","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
