    Abstract: Grade retention and early dropout are two of the biggest challenges facing education systems in middle-income countries today, representing waste in school resources. We investigate whether reducing parent-school information gaps can improve outcomes that are early-warning signals for grade retention and dropout. We conducted an experiment in low-income schools in Chile to test the effects and behavioral changes triggered by a program that sends attendance, grade, and classroom behavior information to parents via weekly and monthly text messages. Our 18-month intervention raised average math GPA by 0.09 of a standard deviation and increased the share of students satisfying attendance requirements for grade promotion by 4.5 percentage points. Treatment effects were larger for students at higher risk of later grade retention and dropout. We find some evidence of positive classroom spillovers. Leveraging existing school inputs to implement a light-touch, cost-effective information intervention can improve education outcomes in lower-income settings.

  2. By: Dix-Carneiro, Rafael; Goldberg, Pinelopi Koujianou; Meghir, Costas; Ulyssea, Gabriel
    Abstract: We build an equilibrium model of a small open economy with labor market frictions and imperfectly enforced regulations. Heterogeneous firms sort into the formal or informal sector. We estimate the model using data from Brazil, and use counterfactual simulations to understand how trade affects economic outcomes in the presence of informality. We show that: (1) Trade openness unambiguously decreases informality in the tradable sector, but has ambiguous effects on aggregate informality. (2) The productivity gains from trade are understated when the informal sector is omitted. (3) Trade openness results in large welfare gains even when informality is repressed. (4) Repressing informality increases productivity, but at the expense of employment and welfare. (5) The effects of trade on wage inequality are reversed when the informal sector is incorporated in the analysis. (6) The informal sector works as an "unemployment," but not a "welfare buffer" in the event of negative economic shocks.

    Abstract: The paper presents empirical evidence from Brazil on the bidirectional relationship between inequality and the COVID-19 crisis: racial, regional and income inequalities have both aggravated the pandemic and been exacerbated by it. The paper provides a measure of social risk factors to COVID-19, which is positively associated with the number of Covid-19 cases across Brazilian states. This is complemented by a discussion of the country's inequalities in access to healthcare and in the incidence of comorbidities, which elucidates observed disparities in the need of a ventilator and in the number of deaths by COVID-19. Finally, our empirical analysis suggests that the substantive fiscal effort in the country and particularly the implementation of the cash relief program Auxílio Emergencial neutralized the short-term increase in wage disparities but has been insufficient to neutralize the cost of multi-dimensional structural inequalities on Brazil’s death tolls.
