We study the aggregate and heterogeneous effects of a front-of-package labeling policy implemented in Chile. We find that consumers reduced their sugar and caloric intake by 9% and 6%, respectively. On the demand side, labels prompt consumers to substitute within categories rather than switching between categories. Within-category responses are more pronounced when labels provide new information. On the supply side, we observe bunching at regulatory thresholds, with substantial heterogeneity across categories, consistent with differing costs of product reformulation.

Using linked employer-employee data from Brazil, we document a significant gender pay gap, which is largely attributed to women working at lower-paying employers. To interpret this fact, we develop an equilibrium search model with endogenous firm pay, amenities, and hiring. We provide a constructive proof of identification of all model parameters. The estimated model suggests that amenities are important for both men and women, and that compensating differentials account for half of the gender pay gap.

Multinational enterprises are at the centre of policy debates in low- and middle-income countries. As some of the most productive and innovative firms in the world, which are at the core of global supply chains, multinational enterprises (MNEs) can accelerate development in the countries hosting them, both directly with their presence, and indirectly through linkages to local economic actors.

Data is the new oil. It is the fuel for AI, a firm asset, a strategic advantage, information for prediction, a productivity booster, a privacy concern, a by-product of transactions, and a means of payment. How can we update traditional economic and finance frameworks to include a role for data and use these updated frameworks to measures it economic impact?

Social movements are catalysts for crucial institutional changes. To succeed, they must coordinate members’ views (consensus building) and actions (mobilization). We study union leaders within Myanmar’s burgeoning labor movement. Union leaders are positively selected on both ability and personality traits that enable them to influence others, yet they earn lower wages. In group discussions about workers’ views on an upcoming national minimum wage negotiation, randomly embedded leaders build consensus around the union’s preferred policy.

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.

We recover valuations of time using detailed data from a large ride-hail platform, where drivers bid on trips and consumers choose between a set of rides with different prices and wait times. Leveraging a consumer panel, we estimate demand as a function of both prices and wait times and use the resulting estimates to recover heterogeneity in the value of time across consumers. We study the welfare implications of personalized pricing and its effect on the platform, drivers, and consumers.
