Evidence from a  \ntop university in Brazil 􀀃  \nRodrigo Oliveiray Henrique Mottez Alei Santos x  \nDecember 2, 2024  \nAbstract  \nUsing two rich administrative data sets and a rule of admission at one top university in Brazil that splits students into two classes, we apply a regression discontinuity design to study the e􀀋ect of class allocation on academic performance and labor market outcomes. The last student of the 􀀌rst class will have higher-ability peers but a lower ordinal rank than the 􀀌rst student of the second class. These e􀀋ects usually play in di􀀋erent directions. The main results suggest that the academic outcomes of a􀀎rmative action students in technology and health sciences majors are negatively impacted by being the last students in the 􀀌rst class. However, this negative e􀀋ect does not translate into the labor market outcomes.  \nKeywords: a􀀎rmative action, peer e􀀋ect, ranking e􀀋ect, Brazil, education.  \nJEL Codes: I24 .

Several studies estimate the causal e􀀋ect of AA policies on students' performance and labor market outcomes in the US (Bleemer, 2022; Arcidiacono, 2005), India (Bagde et al. , 2016), and Brazil (Francis-Tan and Tannuri-Pianto, 2018; Oliveira et al. , 2023) . However, these studies have not yielded conclusive results, though some suggest the presence of a certain degree of mismatch. The existing literature and experts suggest that mismatch primarily stems from misconceptions about the chosen major and inadequate preparation. In addition, other factors may contribute to the lower performance of a􀀎rmative action students, such as peer quality, peer pressure, a lack of sense of belonging, motivation, and future expectations. Nonetheless, the causal e􀀋ects of peers and ranking on a􀀎rmative action students' academic and labor market outcomes in developing country contexts are not well documented. Therefore, this paper investigates whether a lower ranking outweighs the potential bene􀀌ts of having better peers.  \nWe leverage a unique rule of class assignment in a prestigious Brazilian university to examine the impact of class composition on AA students' academic and labor market outcomes. Under this assignment rule, 􀀌rst-year students are divided into classes that commence either at the beginning or in the middle of the subsequent academic year.1 This division is based on their ranking in the entry exam and their applicant status { whether an AA applicant or not. The highest-ranked students are assigned to the 􀀌rst semester, which starts between February and March, while the remaining students begin classes in the second semester, between July and August. Within the same major and admission year the last student in the 􀀌rst class holds a lower relative rank compared to the 􀀌rst stude","cbCaivxrC6htC0XU","https://ap.wps.com/l/cbCaivxrC6htC0XU","pdf",3764359,2,1,49,"English","en",105,"# Abstract\n# Introduction\n## Class assignment rule and student ranking\n## Identification strategy and regression discontinuity design\n## Data and study setting","[{\"question\":\"What assignment mechanism is used to allocate students into classes?\",\"answer\":\"First-year students are divided into classes starting either in the beginning or in the middle of the subsequent academic year, based on vestibular ranking and applicant status (affirmative action or regular).\"},{\"question\":\"How does the regression discontinuity design identify the effects of class allocation?\",\"answer\":\"The design uses the class assignment rule and the entrance exam score as the running variable, comparing students close to the cutoff created by the starting-semester assignment.\"},{\"question\":\"What are the main findings on academic and labor market outcomes for affirmative action students?\",\"answer\":\"Academic outcomes are negatively impacted when affirmative action students are the last in the first class for technology and health sciences majors, but these negative effects do not translate into labor market outcomes.\"}]","Class Allocation -
