What Do (Thousands of) Union Do? Union-Specific Pay Premia and Inequality (joint with Ellora Derenoncourt, Lorenzo Lagos, and Claire Montialoux)
CEPR Discussion Paper #20557, NBER Working Paper #34139,
We study the role of union heterogeneity in shaping wages and inequality among unionized workers. Using linked employer-employee data from Brazil and job moves across multi-firm unions, we estimate over 4,800 union-specific pay premia. Unions explain 3–4% of earnings variation. While unions raise wages on average, the standard deviation in union effects is large (6-7%). Validating our approach, wages fall in markets with higher vs. lower union premia following a nationwide right-to-work law. Linking premia to detailed data on union attributes, we find that unions with strike activity, collective bargaining agreements, internal competition, and skilled leaders secure higher wages. High-premium unions compress wage gaps by education while the average union exacerbates them. Post right-to-work, however, worker support for high-premium unions falls when between-group bargaining differentials are large. Our findings show that unions are not a monolith—their structure and actions shape their wage effects and, consequently, worker support.

Greener on the Other Side: Inequity and Tax Compliance (joint with Michael Best, Luigi Caloi, Evan Kresch, Joana Naritomi and Laura Zoratto)
CEPR Discussion Paper #20510, NBER Working Paper #34062
Governments frequently use proxies for deservingness — tags — to implement progressive tax and transfer policies. These proxies are often imperfect, leading to misclassification and inequities among equally deserving individuals. This paper studies the efficiency effects of such misclassification in the context of the property tax system in Manaus, Brazil. We leverage quasi-experimental variation in inequity generated by the boundaries of geographic sectors used to compute tax liabilities and a large tax reform in a series of augmented boundary discontinuity designs. We find that inequities significantly reduce tax compliance. The elasticity of compliance with respect to inequity is between 0.12 and 0.25, accounting for half of the overall change in compliance at the boundaries. A simple model of presumptive property taxation shows how mistagging affects the optimal tax schedule, highlighting the opposite implications of responses to the level of taxation and to inequity for optimal tax progressivity. Interpreting our findings through the lens of the model implies that optimal progressivity is around 50% lower than it would be absent inequity responses. These results underscore the importance of inequity for public policy design, especially in contexts with low fiscal capacity.
Cash Transfers and the Local Economy: Evidence from Brazil (joint with Joana Naritomi and Joana Silva)
CEPR Discussion Paper #16286
Cash transfers have been adopted worldwide and credited with significant reductions in poverty. However, their economy-wide effects continue to spark heated debates, particularly due to potential adverse effects on the labor market. This paper studies the impact of a flagship government-run program – Bolsa Família in Brazil – on local economies in a context where such concerns are particularly strong, as eligibility is means-tested. We find that an expansion of the program positively affected local economic activity using variation in the size of the reform across municipalities. The results are consistent with cash transfers stimulating local demand, despite means testing. These economy-wide effects substantially increase the marginal value of public funds of the reform, raising it above the value of a non-distortionary transfer.

Access to Justice and Social Protection (joint with Diogo Britto, Lorenzo Germinetti, Joana Naritomi, and Breno Sampaio)
AEA Papers and Proceedings (2025), vol. 115, pp. 329–334. doi: 10.1257/pandp.20251060
Governments in developing countries are expanding social protection policies, yet coverage remains imperfect. This paper explores how the justice system influences coverage and the consequences of unequal access to justice for targeting. Using administrative microdata from Brazil, we document how two distinct groups—displaced workers and the elderly poor—resort to the courts to secure social protection. Using the justice system for this purpose correlates with key individual characteristics—notably income and geographical distance from courts—suggesting that barriers to accessing justice influence policy targeting.
Job Displacement Insurance in Developing Countries (joint with Gustavo Gonzaga and Joana Naritomi)
(forthcoming in The Handbook on Social Protection: Local Solutions for Global Poverty, edited by Rema Hanna and Ben Olken)
This chapter highlights how a small but growing body of work has started to shed light on the need for and the design of Job Displacement Insurance policies in developing countries. Much of this evidence uses data from Brazil, which allows us to discuss various aspects of Job Displacement Insurance policies while holding constant the institutional context. We also discuss evidence from other settings whenever it is available and highlight important evidence gaps for future research.
Sanitation and Property Tax Compliance: Analyzing the Social Contract in Brazil (joint with Evan Plous Kresch, Mark Walker, Michael Carlos Best, and Joana Naritomi)
Journal of Development Economics (2023), vol. 160, 102954. doi: 10.1016/j.jdeveco.2022.102954
This paper investigates the role that sanitation plays in upholding the social contract, whereby citizens pay taxes in exchange for governments providing goods and services. We study the case of Manaus, Brazil, where sewer connections vary considerably across the city and property taxes are calculated in a presumptive manner that does not account for a household's access to sanitation. We find that households with access to the city sewer system are signicantly more likely to pay their property tax, relative to households that only have access to latrines or lack access to improved sanitation entirely. Our evidence is consistent with a role for the social contract in this decision, as households with sewer systems are more likely to have positive attitudes towards the municipal government.

Assortative Matching or Exclusionary Hiring? The Impact of Firm Policies on Racial Wage Differences in Brazil (joint with Lorenzo Lagos, Edson Severnini, and David Card)
NBER Working Paper #25176
American Economic Review (2021), vol. 111, no. 10, pp. 3418-3457. doi: 10.1257/aer.20181596
We measure the effects of firm policies on racial pay differences in Brazil. Nonwhites are less likely to be hired by high-wage firms, explaining about 20% of the racial wage gap for both genders. Firm-specific pay premiums for nonwhites are also compressed relative to whites, contributing another 5% for that gap. A counterfactual analysis reveals that about two-thirds of the under-representation of nonwhites at higher-wage firms is explained by race-neutral skill-based sorting. Non-skill-based sorting and differential wage setting are largest for college-educated workers, suggesting that the allocative costs of discriminatory hiring and pay policies may be relatively large in Brazil.
Informal Labor and the Efficiency Cost of Social Programs: Evidence from Unemployment Insurance in Brazil (joint with Gustavo Gonzaga)
NBER Working Paper #22608
American Economic Journal: Economic Policy (2021), vol. 13, no. 3, pp. 167-206. doi: 10.1257/pol.20180072
(Winner of the Prêmio Haralambos Simeonidis - Categoria Artigos; received by Gustavo Gonzaga)
It is widely believed that the presence of a large informal sector increases the effi.ciency cost of social programs in developing countries. We evaluate such claims for the case of Unemployment Insurance (UI) by combining an optimal UI framework with comprehensive data from Brazil. Using quasi-experimental variation in potential UI duration, we find clear evidence for the usual moral hazard problem that UI reduces incentives to return to a formal job. Yet, the associated effi.ciency cost is lower than in the U.S., and is lower in labor markets with higher informality within Brazil. This is because formal reemployment rates are lower to begin with where informality is higher, so that a larger share of workers would draw UI benefits absent any moral hazard. In sum, efficiency concerns may actually become more relevant as an economy formalizes.

Hysteresis and the Welfare Effect of Corrective Policies: Theory and Evidence from an Energy-Saving Program (joint with Francisco Costa)
NBER Working Paper #24608
Journal of Political Economy (2021), vol. 129, no. 6, pp. 1705-1743. doi: 10.1086/713729
This paper provides stark evidence of hysteresis – the failure of an effect to reverse itself as its underlying cause is reversed – in energy demand. We estimate that half of the 23%-reduction in residential electricity use caused by a 9-month-long policy that was imposed on millions of Brazilians has persisted for at least 12 years. We examine the implications of our finding by extending the traditional welfare analysis of corrective policies to allow for hysteresis. Our estimate highlights that failing to take hysteresis into account could severely bias the welfare evaluation of policies aimed at reducing (long-run) energy demand.

Job Displacement Insurance and (the Lack of) Consumption-Smoothing (joint with Joana Naritomi)
NBER Working Paper #25789
American Economic Review (2021), vol. 111, no. 3, pp. 899-942. doi: 10.1257/aer.20190388
We study the spending profile of workers who experience both a positive transitory income shock (lump-sum severance pay) and a negative permanent income shock (layoff). Using de-identifi.ed expenditure and employment data from Brazil, we show that workers increase spending at layoff by 35% despite experiencing a 14% long-term loss. We find high sensitivity of spending to cash-on-hand across consumption categories and for several sources of variation, including predictable income drops. A model with present-biased workers can rationalize our findings, and highlights the importance of the timing of benefit disbursement for the consumption-smoothing gains of job displacement insurance policies.

Bounds on Treatment Effects in Regression Discontinuity Designs with a Manipulated Running Variable (joint with Miikka Rokkanen and Christoph Rothe)
NBER Working Paper #22892
Quantitative Economics (2020), vol. 11, pp. 839-870. doi:10.3982/QE1079
The key assumption in regression discontinuity analysis is that the distribution of potential outcomes varies smoothly with the running variable around the cutoff. In many empirical contexts, however, this assumption is not credible; and the running variable is said to be manipulated in this case. In this paper, we show that while causal effects are not point identified under manipulation, one can derive sharp bounds under a general model that covers a wide range of empirical patterns. The extent of manipulation, which determines the width of the bounds, is inferred from the data in our setup. Our approach therefore does not require making a binary decision regarding whether manipulation occurs or not, and can be used to deliver manipulation-robust inference in settings where manipulation is conceivable, but not obvious from the data. We use our methods to study the disincentive effect of unemployment insurance on (formal) reemployment in Brazil, and show that our bounds remain informative, despite the fact that manipulation has a sizable effect on our estimates of causal parameters.

Social Protection and Job Displacement in Developing Countries (joint with Joana Naritomi)
International Growth Centre Policy Brief (August 2019)
Across the development path, social insurance programmes such as job displacement insurance schemes become an increasingly important part of governments’ role. This brief uses unique administrative data from São Paulo, Brazil, to study displaced workers’ need for insurance and the insurance value of the two most common government-mandated job displacement insurance programmes: severance pay (SP) and unemployment insurance (UI). The results show the need for job displacement insurance is sizable, even in a context of high informality. Moreover, we find that the insurance value provided by these programmes can be very sensitive to their disbursement policy. This is particularly relevant for SP schemes, which are much more common than UI schemes in developing countries. The authors make three policy recommendations relevant to policymakers across the developing world.
Value Added Tax in developing countries: Lessons from recent research (joint with Joana Naritomi)
International Growth Centre (IGC), Policy Brief (May 2018)
Today, Value Added Taxes (VAT) exist in more than 160 countries, including in many developing countries that have modernized their tax systems in the past decades. Eighty percent of countries in sub-Saharan Africa have adopted the VAT, and it is now responsible for typically raising around one-quarter of all tax revenue. Moreover, countries continue to adapt and reform their VAT systems, sometimes substantially, such as India and Ghana did in 2017. This brief discusses lessons from several studies, which have shed new light on the strengths and weaknesses of VAT systems. It also highlights important topics that could benefit from better evidence.
