Economist at the Chicago FED.
I received my PhD from the University of Chicago in 2021. Former Postdoctoral fellow at the IIES.
In my research, I use micro-data to estimate macroeconomic models and derive policy implications. My research interests are in macroeconomics, labor economics, development, and public finance.
Developing countries rely on technology created by developed countries. This paper demonstrates that such reliance increases wage inequality but leads to greater production in developing countries.
Developing countries rely on technology created by developed countries. This paper shows using model and data that the dependence of developing countries on technology made by developed countries increase wage inequality but leads to higher production in developing countries. I study a Brazilian innovation program that taxed the leasing of international technology to subsidize innovation. Exploiting heterogeneous exposure, I show that the innovation program led firms to replace technology licensed from developed countries by in-house innovations. The replacement of international technology by national technology led to a decline in employment and in the share of high-skilled workers in the firm. I explain these facts with a model of directed technological change and cross-country technology transactions. Firms in a developing country can either innovate or lease technology from a developed country. These two technologies endogenously differ in productivity and skill bias due to factor supply differences in the two countries. I show that the difference in skill bias and productivity can be identified with closed-form solutions by the effect of the innovation program on the firm’s expenditure share and employment. Calibrating the model to reproduce these elasticities, I find that increasing the share of firms patenting in Brazil by 1 p.p. decreases the skilled wage premium by 0.02% and production by 0.2%.
Exogenous increase in the relative income of voters causes an increase in public goods provision, contrary to standard political economy theories.
I show that an exogenous increase in the relative income of voters causes an increase in public goods provision, contrary to standard political economy theories. I explain this result with a model of complementarity between consumption and public goods. Estimating the model to reproduce the micro-elasticities, I find that compulsory voting would decrease the government size by 7% despite reducing the average income of voters by 6%.
Voters who could benefit from welfare policies vote against them because they hold negative ideologies against redistribution.
What are the quantitatively relevant determinants of redistribution? I describe a structural method to identify different channels affecting the social choice of redistribution and estimate the counter-factual effect of institutional reforms. The method relies on a dynamic heterogeneous agents model estimated using micro-data on voting and on the support for redistribution. I found that pecuniary gains play a negligible role in shaping redistribution. Voters who could benefit from redistribution support and vote for low transfers motivated by social preferences and not pecuniary gains. Because social preferences are more important than income in predicting support for redistribution, increasing voter turnout or capping campaign contributions would have no effect on redistribution.
Can anti-dumping tariffs increase employment?
Can anti-dumping tariffs increase employment? To answer this question we compile data on all anti-dumping (AD) investigations in Brazil, which we match to firm-level administrative employment information. Using difference-in-differences, we estimate the effect of AD tariffs on trade, the protected national suppliers, and the sectors linked to these suppliers. In response to an AD tariff, imports decrease and employment increases in the protected sector. Moreover, downstream firms decrease employment, while upstream ones are not affected. To quantify the aggregate effect of these tariffs, we build a model with international trade, input-output linkages, and labor force participation. The model can reproduce the micro-elasticities we find, as well as the aggregate moments of the Brazilian economy. We show that the Brazilian AD policy increased employment by 0.06%, but they decreased welfare by 2.4%. Using tariffs, the government can increase employment by as much as 2.8%.
A larger monetary requirement increases welfare by reducing moral hazard discouraging low-pay and temporary jobs
In the US, unemployed workers must satisfy two requirements to receive unemployment insurance (UI): a tenure requirement that stipulates the minimum qualifying work spell and a monetary requirement that determines a past minimum wage. This paper develops a heterogeneous agents model with history-dependent UI benefits in order to quantitatively obtain an optimal UI program design. We first conduct an empirical analysis using the discontinuity of UI rules at state borders and find that both the monetary and the tenure requirement reduce unemployment. The monetary requirement decreases the number of employers and the share of part-time workers, while the tenure requirement has the opposite effect. We then use a quantitative model to rationalize these results. When the tenure requirement is long, workers tend to accept more low paying jobs to become eligible for UI sooner and to protect themselves from risk, while the monetary requirement works conversely. We show that, because it mitigates moral hazard, the monetary requirement can generate higher welfare levels than an increase in the length of the tenure requirement.
What is the most cost-efficient way to impose trade sanctions against Russia?
Trade sanctions are a common instrument of diplomatic retaliation. To guide current and future policy, we ask: What is the most cost-efficient way to impose trade sanctions against Russia? To answer this question, we build a quantitative model of international trade with input-output connections. Sanctioning countries simultaneously choose import tariffs to maximize their income and to minimize Russia’s income, with different weights placed on these objectives. We find, first, that for countries with a small willingness to pay for sanctions against Russia, the most cost-efficient sanction is a uniform, about 20% tariff against all Russian products. Second, if countries are willing to pay at least US$0.7 for each US$1 drop in Russian welfare, an embargo on Russia’s mining and energy products – with tariffs above 50% on other products – is the most cost-efficient policy. Finally, if countries target politically relevant sectors, an embargo against Russia’s mining and energy sector is the cost-efficient policy even when there is a small willingness to pay for sanctions.
The quota for disabled workers in Brazil increased the employment of disabled workers at a large employment and welfare cost for nondisabled workers.
I study the effect of a quota for disabled workers on the labor market and on welfare. Using a task-based model, I show that the effect of a quota will depend on the productivity of disabled workers and their labor supply elasticity. I estimate the productivity of disabled workers using variation from inspections of the quota. I find that the quota increased the hiring of disabled workers, but it reduced wage and employment of non-disabled workers, suggesting that disabled workers are of low-productivity. I estimate the labor supply elasticity of disabled workers using heterogeneous exposure across regions. I find that the quota increased the wage and labor force participation of disabled workers. Using the model calibrated to the empirical estimates, I find that the quota for disabled workers decreased welfare by 0.33% and forced the government to increase marginal taxes. However, alternatively, a subsidy for disabled workers could increase welfare by 0.29%.
