The sustainable competitive advantage of incumbent firms has been widely discussed, but its relation to the integral processes incorporated into product design and production remains poorly understood. This study investigates how differences in product architecture, that is, the presence of an...

This paper examines sectoral growth patterns across Chinese provinces during the country's economic takeoff in the early 2000s, following major policy reforms including trade liberalization, infrastructure expansion, business climate improvements, and relaxed rural-to-urban migration...

Limited competition in public procurement remains a persistent concern, yet the reasons for low participation are not well understood. We conduct a conjoint survey experiment that targets both potential and actual bidders in Finland. We present real firms with hypothetical tender scenarios,...

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...

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...

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...

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...

We study whether firm-level heterogeneity helps explain U.S. macroeconomic fluctuations in response to aggregate shocks. Using quarterly Compustat and CRSP data from 1986 to 2025, we construct two revenue-based statistics inspired by the Melitz (2003) model: the average firm and the marginal...

Understanding how large firm entry reshapes local housing markets is crucial for evaluating place-based development strategies in regional science. This study investigates the housing market response to Taiwan Semiconductor Manufacturing Company (TSMC)'s decision to build a semiconductor...

This Handbook is intended to act as a reference for those agri-food producers planning for, or in the process of entering, the Vietnamese market. This Handbook provides step-by-step guides on entering the agri-food market in Vietnam including relevant information such as analysis of the...

We consider a market in which a platform hosts third-party monopolistic complementors. Users are segmented into single-use and multi-use consumers, and services exhibit network externalities. In the agency model, the presence of multi-use consumers leads complementors to set inefficiently high...

This paper characterizes the short- and long-run Cournot equilibrium with heterogeneous firms and stochastic technological change. In our model, firms have different technologies with heterogeneous fixed and variable costs and various degrees of markups. In a framework with homogeneous firms,...

Policies supporting small businesses are popular among policymakers but often criticised by economists for their potential to distort the economy. This paper provides a comprehensive evaluation of a unique policy that subsidises the first employee. Empirically, we find that the policy led to a...

This paper studies the interaction between the decrease in the gender pay gap and the stagnation in the careers of younger workers, analyzing data from the United States, Italy, Canada, and the United Kingdom. Our findings highlight the importance of labor-market entry to understand the...

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...

This study constructs a model of exclusive-offer competition between two existing up-stream firms. Under exclusive-offer competition, the upstream firm's profit depends on the rival's exclusive offer. If the rival makes an exclusive offer acceptable for the downstream firm, the upstream firm is...

This paper examines the welfare implications of priority service in a frictional search environment with heterogeneous outside options. Priority search facilitates expedited matching with public options in the market by charging a service premium. Our main analysis demonstrates that a...

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...
