Welcome! I'm a Ph.D. Candidate in Economics at UC Berkeley. My fields of interest are Public Economics and Labor Economics. I earned a B.S. and M.A. in Economics from Universidad Nacional de La Plata (UNLP), Argentina.
I will be on the job market in 2019-2020 and available for interviews at the 2020 ASSA Meetings in San Diego.

We exploit a large and quasi-randomized 2.5 year-long income tax holiday to identify intertemporal labor responses of high-wage earners to net wage changes. In August 2013, the Argentine government exempted a group of wage earners from the income tax and left the remaining group taxed until February 2016, when the tax break was repealed. Eligibility was based on whether past wage earnings were below a fixed threshold, creating a discontinuity that treated workers who coexist in the same labor market (even in the same firm) with sharply different marginal and average tax rates —effectively 0% for workers below the threshold. Using rich population-wide administrative data and a regression discontinuity design, we estimate a precise and very small wage earnings elasticity of 0.017 to this large, salient, and temporary income tax change. Responses are larger for more flexible outcomes (overtime hours) and more elastic groups (job switchers and managers). We also find avoidance responses from new entrants who faced no tax if their first monthly wage was below the fixed threshold. The strategic entry below the threshold to dodge taxes required coordination with employers. Our evidence challenges the standard model of labor supply and demand, and points toward rigidities in the labor market which requires employer-employee cooperation for wage earners to respond to tax changes.
We explore how the way in which tax credits are disbursed affects employer's behavior, wages, and employment. We exploit a change in the payment system that was gradually rolled out between 2003 and 2010 in Argentina. Under the old system, employers were intermediaries that paid family allowances to their employees together with their corresponding salary, and they were allowed to deduct this transfer from employer social security contributions. The new system eliminated the intermediary role played by employers and centralized the payments in a government agency that started disbursing the allowances directly to eligible workers. Using employer-employee micro-data and an event-study design, we show that the way tax credits are disbursed is not neutral. Our evidence suggests that employers shift part of the incidence of the transfer by paying lower wages. The effect is mostly driven by big firms and firms located in less dense areas (proxy for monopsonistic power). Our findings are therefore in line with the hypothesis that transfers are not all captured dollar for dollar by workers.
We estimate the response of self-employed and firms to two revenue taxes, Monotributo and the Turnover Tax, across the turnover distribution using rich administrative data from Argentina. We exploit several revenue-dependent discontinuities that provide incentives to underreport taxable income combined with a bunching design to estimate revenue elasticities. We also explore heterogeneities by firm size, type of activities, and type of taxpayers. In the case of small firms, we find sizeable bunching below the thresholds that is stronger for higher tax incentives. The response is stronger in sectors that have more space for manipulation, such as service-based activities. In the case of medium and large firms, bunching is more muted but it suggests that even large firms are able to underreport their gross sales to avoid facing higher tax rates. Firms also seem to find more costly the indirect administrative cost of becoming a collection agent than the direct fiscal cost of the turnover tax. We cannot rule out, however, that large firms adjust other margins (or taxes) to compensate for the higher tax pressure.
We disentangle the extent of imperfect competition in product and labor markets using plant-level data. We derive a formula for the ratio between markups and markdowns assuming cost-minimizing firms that face upward-sloping labor supply and downward-sloping product demand curves. We then separate this combined measure of market power by estimating firm-level labor supply elasticities instrumenting wages with intermediate inputs. Our results suggest that both markets exhibit imperfect competition, but the variation is mainly driven by markups. We also estimate the relative gains of removing market power dispersion on allocative efficiency, finding that markups are more important on TFP than markdowns.
WORK IN PROGRESS (pipeline)
Two understudied areas in Public Finance are the role of tax professionals and the role of networks in tax administration and enforcement (Slemrod, 2018). In this project I seek to answer two questions: First, whether it is more cost-effective to communicate tax preparers or taxpayers to improve tax compliance; Second, whether there are spillover effects from targeted to non-targeted taxpayers that form part of the same network (those sharing the same accountant). To that end, I run a large scale randomized communication experiment where I send deterrence emails to taxpayers and/or accountants (about 100,000 taxpayers in the treatment group and 900,000 in the control group).
We study the relationship between tax filings and tax withholdings for the Argentine gross receipts tax on businesses and we shed light on the role of tax preparers in that relationship. Firms have to file a gross receipt tax return every month through a centralized online platform and can (i) claim a refund if the amount withheld in advance (third-party reported by suppliers and clients) exceeds the tax liability, or (ii) remit the difference if the tax liability is higher than withholdings. Using rich administrative data we first document sharp bunching exactly at the point where tax liabilities (reported by the firm) equal tax withholdings (third-party reported) and argue that this pattern is due to strategic under-reporting of income so that the tax balance matches the withholding shown by the online platform. Second, by linking firms to tax preparers through shared contact information we study the role of accountants on this behavior. We analyze how correlated are the behaviors of firms who share the same accountant (network). We find a positive relationship between accountants and the bunching behavior observed on their clients. We also exploit information on past audits and show that, within a network, non-audited firms respond to their peer's audit, suggesting that tax preparers might act as diffusers of information across firms.
We study the efficiency and distributional effects of price controls. Despite the controversy surrounding the effects of this regulation, surprisingly little has been done in practice to test the contrasting predictions. In this project, we aim to fill this gap by exploiting scanner data and quasi-experimental variation from price regulations introduced in the Argentine retail sector in 2014. We first study the effect of price controls on the supply of targeted products, spillovers on similar products, and explore how it differs by the level of concentration in the product's industry. Guided by these results, in the second part of the paper we estimate markups at the product level and explore whether price controls can affect the level of concentration in the industry. In the third part, we study the distributional and welfare effects of price controls.
We analyze the economic effects of taxes on consumption goods highly demanded by high-income people. The identification strategy hinges on quasi-random variation from a tax on luxury cars applied to automobiles above a price threshold ("notch") in Argentina. This surtax went from 0% to 10% in 2008, then increased to 50% in 2014, and decreased to 20% in 2016. We use data from the automobile industry spanning the period 2003-2019 and a diff-in-diff design to estimate own-price and cross-price elasticities by comparing the sales of brand-models above (affected) and below (not affected) the price cutoff. Our estimates allow us to test the predictions from the Atkinson-Stiglitz theorem.
