摘要：We study tax and regulatory policy in the legal marijuana market using unique administrative data from Washington state. Washington's retail entry restrictions have resulted in firms with substantial market power who behave like local monopolists. We show how the presence of market power causes tax and regulatory policy recommendations to differ from standard models that assume perfect competition. Combining structural demand models with measured pass-through, we show that marijuana is not ove...

摘要：Optimally reallocating human capital to tasks is key for an organization to successfully navigate a transition. We study how to design employment contracts to allocate employees to different valuable projects within an organization given two simultaneous challenges: The employees have private information about their cost of effort, and they exert unobservable effort. The optimal contract menu pairs a higher probability of assignment to a valuable project with a lower bonus in case of success. ...

摘要：We examine the implications of consumer privacy when preferences today depend upon past consumption choices, and consumers shop from different sellers in each period. Although consumers are ex ante identical, their initial consumption choices cannot be deterministic. Thus, ex post heterogeneity in preferences arises endogenously. Consumer privacy improves social welfare, consumer surplus and the profits of the second-period seller, while reducing the profits of the first period seller, relativ...

摘要：Consumers rely on intermediaries (influencers) such as social media recommendations to provide information about products. The advice may be mixed with endorsement in a way that is unobservable to the follower, creating a trade-off for influencers between the best advice and the most revenue. This article models the dynamic relationship between an influencer and a follower. The relationship evolves between periods of less and more revenue. The model can provide insight into policies such as th...

摘要：Using staggered entry of two dockless bike-sharing firms, we study whether the entrant expands or steals the market from the incumbent in 59 cities. Compared with 23 cities without entry, the entry helps the incumbent to serve more trips, make more bike investment, achieve higher revenue per trip, improve bike utilization, and form a wider and more dispersed network. The market-expanding effect on new users dominates a significant market-stealing effect on old users. These findings, plus a the...

摘要：We analyze a competitive labor market in which workers signal their productivities through education, and firms have the option of auditing to learn workers' productivities. Audits are costly and non-contractible. We characterize the trade-offs between signaling by workers and costly auditing by firms. Auditing is always associated with (partial) pooling of worker types, and education is used as a signal only if relatively few workers have low productivity. Our results feature new auditing pat...
