Firms often choose with whom to compete and how similar or how different their products should be relative to those of their rivals. This paper investigates this issue in the app economy by studying the determinants of mobile app success. We leverage natural language processing and unsupervised...

Conventional wisdom suggests that information transparency about prices lowers prices and markups by intensifying seller competition. However, in markets with costly buyer entry, price transparency also draws in more buyers, increasing demand-side competition and putting upward pressure on...

This paper reexamines the trade creation effects of migration using a large sample of 180 countries from 1995 to 2023. We estimate a structural gravity model of bilateral trade augmented with migration stocks, investigating whether immigration to OECD countries relates to the extensive and...

We study how the end of the quota system for textiles and clothing products in the American and European markets on January 1, 2005, affected China’s exports to third countries, where policy was unchanged. Using a difference-in-differences approach, we find that the number of Chinese firms...

I study how third-party firms respond when a platform owner enters its own marketplace, analyzing Apple's entries into App Store submarkets from 2016-2021. Using text embeddings to define markets and a staggered difference-in-differences design, I find that Apple's entry deters new competitors...

This paper studies how commission rates affect app entry across platforms. We examine an increase in Android game commission rate from 30% to 50% in China in 2014 and its impact on Android and iOS app stores, separately, in a difference-in-differences framework. We find a direct negative entry...

Many auctions and procurement contests entail nontrivial bidding costs, which makes the bidders' participation decisions endogenous to the auction design. We analyze the effect of different auction rules on potential bidders' incentives to participate. We focus on first-price auctions with...

We show that adverse selection is a key determinant of banking market structure. Using data on US bank branches over 1981-2016, we study banks' decisions to expand or contract geographically. First, banks are more likely to expand in counties that are similar, in terms of industry shares, to...

We revisit the classic chain-store paradox by introducing a novel element: the arrival of exogenous, public signals about the incumbent's private type over time. As the horizon lengthens, two opposing forces come into play. On one hand, standard reputational incentives grow stronger; on the...

Many countries seek to promote exports by subsidizing market access, but evidence on such efforts has been mixed. We present the first randomized evaluation of a government financial-support program explicitly targeting exports, the Tasdir+ program in Tunisia. The program offered matching grants...
