We examine merging firms' additions and removals of products for a sample of 66 mergers across a wide variety of consumer packaged goods markets. We find that mergers lead to a net reduction in the number of products offered by merging firms. Merging firms tend to both drop and add products at...

This paper presents a new method for estimating discrete games based on bounds of conditional choice probabilities. The method does not require solving the game and is scalable to models with many firms and many discrete decisions. We apply the method to study merger effects on firm entry and...

Green hydrogen may decarbonize sectors which are difficult to electrify, and the recent Inflation Reduction Act (IRA) provides tax credits to encourage hydrogen production. We analyze a model in which hydrogen produced using electricity replaces natural gas. The electricity may be procured from...

Individuals might experience negative utility from not consuming a popular product. For example, being inactive on social media can lead to social exclusion or not owning luxury brands can be associated with having a low social status. We show that, in the presence of such spillovers to...

Forward-looking investments determine the resilience of firms' supply chains. Such investments confer externalities on other firms in the production network. We compare the equilibrium and optimal allocations in a general equilibrium model with an arbitrary number of vertical production tiers....

Individuals might experience negative utility from not consuming a popular product. For example, being inactive on social media can lead to social exclusion or not owning luxury brands can be associated with having a low social status. We show that, in the presence of such spillovers to...

We examine the desirability of granting "safe harbor" provisions to creditors of financial intermediaries in sale-and-repurchase (repo) contracts. Exemption from an automatic stay in bankruptcy enables financial intermediaries to raise greater liquidity and induces entry of intermediaries with...

Opioid overdose death rates in the United States have risen continuously for over three decades, increasing 2,142 percent in total from 1990 to 2020. This is surprising. One might expect drug epidemics to be self-limiting, as policy and individual behavior reacts to observed deaths. We study why...

Many platforms deploy data collected from users for a multitude of purposes. While some are beneficial to users, others are costly to their privacy. The presence of these privacy costs means that platforms may need to provide guarantees about how and to what extent user data will be harvested...
