This paper shows that large, multi-establishment business enterprises face a high cost of middle management in poor countries and that this cost inhibits the growth of the modern sector. We provide new empirical evidence using a database covering compensation for 300,000 middle managers working...

What explains record U.S. house price growth since late 2019? We show that the shift to remote work explains over one half of the 23.8 percent national house price increase over this period. Using variation in remote work exposure across U.S. metropolitan areas we estimate that an additional...

This paper shows that product design shapes search frictions and that intermediaries leverage this channel to increase their rents in the context of the U.S. municipal bond market. The majority of bonds are designed via negotiations between a local government and its underwriter. They are then...

High-speed internet has increased the amount of information available in health care markets. Online information may improve health outcomes if it reduces information frictions and helps patients choose higher quality providers or causes providers to improve quality. We examine how health...

Consumer reviews, especially those expressing concerns of product quality, are crucial for the credibility of online platforms. However, reviews that criticize a product or service may also dissuade buyers from using the platform, creating an incentive to blur the visibility of critical reviews....

This paper surveys the relevant existing literature that can help researchers and policy makers understand the drivers of competition in markets that constitute the provision of artificial intelligence products. The focus is on three broad markets: training data, input data, and AI predictions....

Health insurance plans in the U.S. increasingly use price mechanisms to steer demand for prescription drugs. The effectiveness of these incentives, however, depends both on physicians' price sensitivity and their knowledge of patient prices. We develop a moment inequality model that allows...

The elegant economic picture of rational consumers achieving Pareto optimality through trade in decentralized self-organized markets is blurred by market imperfections and choices inconsistent with consumer self-interest. Behavioral economics has documented these errors in choice, and considered...

Why do low income patients tend to go to lower quality health care providers, even when they are free? We show that differential information about provider quality is an important determinant of this disparity. Our empirical strategy exploits the temporary presence of a website that publicly...

We study whether Amazon engages in self-preferencing on its marketplace by favoring its own brands (e.g., Amazon Basics) in search. To address this question, we collect new micro-level consumer search data using a custom browser extension installed by a panel of study participants. Using this...
