摘要：We explore a novel mechanism of network change that occurs when a firm acquires another one and inherits its network ties. Such node collapse can radically restructure the network in one transaction, constituting a revolutionary change compared with the incremental effect of tie additions and deletions, which have been the focus of prior research. We explore several properties of node collapses: their efficacy in helping firms achieve superior network positions, the externalities they impose o...

摘要：We investigate the factors that affect the growth of Groupon, the leading online daily deals platform. We concentrate on the online-to-offline (O2O) aspect of the business that differentiates it from other e-commerce platforms-its strong connection to local markets. We focus on travel cost and store density, the key local characteristics that affect consumer deal demand and merchant deal offering. Using a comprehensive longitudinal data set on deal offerings and sales across local markets, and...

摘要：We develop a model of advertising markets in an environment where consumers may switch (or multi-home) across publishers. Consumer switching generates inefficiency in the process of matching advertisers to consumers, because advertisers may not reach some consumers and may impress others too many times. We find that when advertisers are heterogeneous in their valuations for reaching consumers, the switching-induced inefficiency leads lower-value advertisers to advertise on a limited set of pub...

摘要：We study how people reconcile conflicting moral intuitions by juxtaposing two versions of classic moral problems: the trolley problem and the footbridge problem. When viewed separately, most people favor action in the former and disapprove of action in the latter, despite identical consequences. The difference is often explained in terms of the intention principle-whether the consequences are intended or incidental. Our results suggest that when the two problems are considered together, a diff...

摘要：A growing empirical literature uses patent citations as a quality-adjusted measure for innovation, despite concerns about the validity of this measure. This paper links patents with objective measures of improvements in the quality of patented inventionsmeasured through performance in field trials for hybrid corn-to examine three potential factors that influence citations: (1) improvements in performance, (2) citing practices of patent attorneys, and (3) citing practices of patent examiners. T...

摘要：A paradox in organizational research on judgment and decision making is that although the law-of-effect in adaptive learning suggests that people's tendency to take a decision decreases after the decision receives negative consequences, people often exhibit an opposite action pattern of escalation of commitment. To address this paradox, this paper proposes that the unit of law-of-effect can be extended from a decision level to a strategy level (i.e., a group of planned decisions). A strategy o...

摘要：Omnichannel environments where customers shop online and offline at the same retailer are ubiquitous, and are deployed by online-first and traditional retailers alike. We focus on the relatively understudied domain of online-first retailers and the engagement of a key omnichannel tactic; specifically, introduction of showrooms (physical locations where customers can view and try products) in combination with online fulfillment that uses centralized inventory management. We ask whether, and if ...
