Equilibrium Effects of Food Labeling Policies
with Nano Barahona and Sebastián Otero
Econometrica, 91(3): 839-868, May 2023
Abstract: We study a regulation in Chile that mandates warning labels on products whose sugar or caloric concentration exceeds certain thresholds. We show that consumers substitute from labeled to unlabeled products—a pattern mostly driven by products that consumers mistakenly believe to be healthy. On the supply side, we find substantial reformulation of products and bunching at the thresholds. We develop and estimate an equilibrium model of demand for food and firms' pricing and nutritional choices. We find that food labels increase consumer welfare by 1.8% of total expenditure, and that these effects are enhanced by firms' responses. We then use the model to study alternative policy designs. Under optimal policy thresholds, food labels and sugar taxes generate similar gains in consumer welfare, but food labels benefit the poor relatively more.

National Institutions and Regional Development at Borders: Evidence from the Americas
with Francisco Gallego, César Huaroto, and Alejandro Sáenz
Applied Economics, 53(2): 205-220, 2020
Abstract: This paper explores how discontinuities created by national borders can influence development across the Americas. We exploit the discontinuous nature of borders jointly with exogenous variation at the national level to identify discontinuous effects on proxies for economic development at the regional and pixel levels. We separate the effects of national institutions from local historical conditions. Our analysis yields three main findings. First, we find important discontinuities in development across national borders for the Americas. Second, we also show that they are, for the most part, caused by institutional differences at the national level and not for differences at the regional level in geography, climate, endowments, and pre-colonization conditions. Third, we also present evidence that differences in national institutions affect human capital at the regional level.
[updated] On the Design of Food Labeling Policies
with Nano Barahona, Sebastián Otero, and Josh Kim
Last update: March 2023
Abstract: We study a regulation in Chile that mandates front-of-package warning labels on products whose sugar or caloric concentration exceeds certain thresholds. We find that after the introduction of the regulation, consumers reduced their overall sugar and caloric intake by 9% and 6%, respectively. This change is explained by consumers buying healthier products and firms reformulating their products. On the demand side, labels induce consumers to substitute within categories rather than between categories. On the supply side, we document bunching at regulatory thresholds, with substantial heterogeneity across categories. We provide insights to inform the design of effective food labeling policies.

Abstract: We study whether, and how, managers can increase government productivity in the context of public health provision. Using novel data from public hospitals in Chile, we document that top managers (CEOs) account for a significant amount of variation in hospital mortality. Using a staggered difference-in-differences design, we then show that a reform which introduced a competitive selection system for recruiting CEOs in public hospitals reduced hospital mortality by approximately 8%. The effect is not explained by a change in patient composition and is robust to several alternative explanations. The financial incentives included in the reform—performance pay and higher wages—do not explain our findings. Instead, we show that the policy changed the pool of CEOs by displacing older doctors with no management training in favor of younger CEOs who had studied management. The mortality effects were driven by hospitals in which the new CEOs had management studies. These CEOs improved operating room efficiency and reduced staff turnover.

The Economics of the Public Option: Evidence from Local Pharmaceutical Markets
with Juan Pablo Atal, José Ignacio Cuesta, and Felipe González
R&R American Economic Review (second round)
Last update: December 2022
Abstract: We study the effects of competition by state-owned firms, leveraging the decentralized entry of public pharmacies to local markets in Chile. Public pharmacies sell the same drugs at a third of private pharmacy prices, because of stronger upstream bargaining and market power in the private sector, but are of lower quality. Public pharmacies induced market segmentation and price increases in the private sector, which benefited the switchers to the public option but harmed the stayers. The countrywide entry of public pharmacies would reduce yearly consumer drug expenditure by 1.5 percent.

Author of Capital in the Twenty-First Century
This is a fascinating book on inequality and taxation in Chile. This collective volume brings the best experts and a refreshing perspective on this central issue. Chile is one of the most unequal countries in the world, partly due to its unfair tax system and the legacy of the Pinochet regime. At a time when the country is rethinking its basic law and social contract, this is a very timely book and a must-read for all citizens of the world.
Coauthor of The Triumph of Injustice: How the Rich Dodge Taxes and How to Make Them Pay
Taxation is one of the most important political — and even philosophical — issues we face as citizens. This groundbreaking book is a treasure trove of information on taxation and inequality in Chile, a rigorous analysis of the changes in taxation that have taken place over the last century, and a vital contribution to the public debate that will resonate for many years in Chile and in Latin America.
