摘要：Standard discrete choice demand models assume that all products are substitutes. Merger analyses based on these models may overstate consumer harm. We develop an estimator that identifies demand complementarity and remains computationally feasible with large choice sets. We apply this estimator to the chips and soda market and find a high degree of complementarity between these product groups. We show that a counterfactual merger ignoring complementarity between PepsiCo/Frito-Lay and Dr. Peppe...

摘要：Our model classifies platforms in the creator economy -for example, Youtube, Patreon, and Twitch-into three business models: pure discovery (helping consumers search for creators); pure membership (enabling direct creator-consumer monetization); and hybrid (combining both). Creators respond to platforms' decisions by choosing their content design along a broad-niche spectrum, trading off between viewership size and per-viewer monetization. With a monopoly platform, moving from pure discovery t...

摘要：We examine the role of pay transparency in inventor productivity by exploiting the staggered adoption of state-level pay secrecy laws, which enhance pay transparency in the workplace. We find a significant increase in inventor productivity of firms located in states that have passed such laws relative to firms elsewhere. This relation is more pronounced for firms in states with lower levels of pre-existing pay transparency. We further show that pay secrecy laws promote inventor productivity by...

摘要：Does enhanced access to data foster or hinder competition among firms? Using a competition-in-utility framework that encompasses many situations where firms use data, we model data as a revenue-shifter and identify two opposite effects: a mark-up effect according to which data induces firms to compete harder, and a surplus-extraction effect. We provide conditions for data to be pro- or anti-competitive, requiring neither knowledge of demand nor computation of equilibrium. We apply our results ...

摘要：This article proposes a dynamic approach to modeling opportunism in bilateral vertical contracting between an upstream monopolist and competing downstream firms. Unlike previous literature on opportunism which has focused on games in which the upstream firm makes simultaneous secret offers to the downstream firms, we model opportunism as a consequence of asynchronous recontracting in an infinite-horizon continuous-time model. We find that the degree of opportunism depends on the absolute and r...

摘要：I study price setting within a network of interconnected monopolists. Some firms possess stronger commitment or bargaining power than others, enabling them to influence the pricing decisions of other firms. Although it is well-understood that multiple marginalization reduces both total profits and social welfare, I show that strategic interactions within the network exacerbate the marginalization problem. Individual profits are proportional to a new measure of network centrality, defined by th...

摘要：We analyze authority allocation to incentivize information acquisition under interdependence. Agents access noisy signals about two states of the world. Beyond costs, acquisition depends on the expected influence on decisions, determined by whether authority is centralized or split among decision-makers. Restricting an agent's information on the extensive margin enhances communication. When such specialization is not feasible, informational congestion may induce similar incentive effects. Spli...

摘要：A general mixture model of contests is introduced, combining stochastic performance and multivariate incomplete information. Performance is determined by a mixture distribution with endogenous weights on a good and bad distribution, respectively. Incomplete information does not increase the complexity of the problem, and actions are unambiguously strategic substitutes when technologies are homogeneous. These properties enable comparative statics with respect to changes in the type distribution...

摘要：We introduce an R&D network formation model where firms choose both R&D efforts and collaboration partners. Neighbors in the network benefit from each other's R&D through technology spillovers, and there exists competition effects reflecting strategic substitutability in R&D. We provide a complete equilibrium characterization, and develop an estimation method that is computationally feasible for large networks. We then conduct an analysis of R&D collaboration subsidies, and find that a subsidy...

摘要：We study the US Anti-Ulcer Drug market, where market exclusivity is granted to the first over-the-counter (OTC) drug independent of prescription drugs' patent expiry. We show that due to the interplay of incentives in the prescription and OTC drug markets, compared to a world with no market exclusivity policy, the status quo design reduces consumer welfare by 1.6 billion USD, as it causes many firms to delay entry into the OTC drug market until prescription drug patents expire. An alternative ...
