We study the spatial expansion of banks in response to banking deregulation in the 1980s and 90s. During this period, large banks expanded rapidly, mostly by adding new branches in new locations, while many small banks exited. We document that large banks sorted into the densest markets, but...

Blockchain-based smart contracts can potentially replace certain traditional contracts through decentralized enforcement and reduced transaction costs. However, scalability is a key bottleneck hindering their broader application and adoption, often leading to concentrated or exclusive networks....

Across many sectors, research has established that management explains a notable portion of productivity differences across organizations. A remaining question, however, is whether it is managers themselves or firm-wide management practices that matter. We shed light on this question by...

Observing the increasingly important roles played by the creation and transmission of information and tacit knowledge, we construct an information-network model incorporating both information transmitters and information aggregators. Given information-processing roles in aggregation or...

We study the demand for government participation in China's venture capital and private equity market. We conduct a large-scale, non-deceptive field experiment in collaboration with the leading industry service provider, through which we survey both sides of the market: the capital investors and...

We provide evidence that over the past 30 years, U.S. firms have expanded their scope of operations. Increases in scope and scale were achieved largely without increasing traditional operating segments. Scope expansion significantly increases valuation and is primarily realized through...

We investigate the impact of a set of place-based subsidies introduced in Turkey in 2012. Using firm-level balance-sheet data along with data on the domestic production network, we first assess the policy's direct and indirect impacts. We find an increase in economic activity in...

The COVID-19 pandemic instigated a big shift in working arrangements. I first describe the scale of this shift in the United States, drawing on the Survey of Working Arrangements and Attitudes and other sources. I then review differences, circa 2023, in work-from-home rates across industries,...

We characterize the evolution of markups for consumer products in the United States from 2006 to 2019. Using detailed data on prices and quantities for products in more than 100 distinct product categories, we estimate flexible demand systems and recover markups under an assumption that firms...

Firms have inefficiently low incentives to innovate when other firms benefit from their inventions and the innovating firm therefore does not capture the full surplus of its innovations. We show that common ownership of firms mitigates this impediment to corporate innovation. By contrast,...
