摘要：We build a unified modeling framework for classical online matching problems and emerging online matching problems with three additional practical features: reusable resources, network resources, and decaying rewards. For online matching problems in the unified framework, we provide a unified performance analysis tool for the greedy policy and its simple variants, which we refer to as greedy-like policies. We prove that greedylike policies can achieve near-optimal performances for online match...

摘要：Demand externalities arise when past sales stimulate future demand. They pervade many consumer markets. To penetrate such markets, how should manufacturers contract with retailers? We formulate the problem as a dynamic game, wherein the retailer can privately observe and control evolving market conditions, and consumers can act either myopically or strategically. Our contribution is threefold. (i) We characterize the optimal contract: It resolves a dynamic tradeoff between exploiting demand ex...

摘要：Committees of experts are widely used to make decisions. We experimentally investigate the relationship between decision making in committees and the assessment of the ability of committee members by evaluators, comparing observed behavior with theoretical predictions. Treatments vary in whether members care only about a statedependent project payoff or also about assessments and whether evaluators can base their assessments only on the decision the committee makes or also on cheap-talk statem...

摘要：The underrepresentation of women in traditionally male-dominated fields of study can generate a lack of role models for female students, influencing their career choices. We investigate whether having higher shares of female professors and classmates throughout undergraduate studies in economics affects female students' labor market outcomes up to five years after graduation. To deal with self-selection into professors and peers, we exploit the assignment rule of students to course sections at...

摘要：The transmission of information is crucial for productivity and growth. However, language differences may limit its effectiveness. This is particularly relevant for knowledge platforms that aim to be global, given the cultural diversity of the pool of users. In this paper, I empirically investigate how the exogenous cost of language affects communication quality and the trade-offs faced by knowledge platforms in implementing their website in multiple languages. I exploit the staggered introduc...

摘要：In this paper, we investigate market design for online gaming platforms. We ask what motivates people to continue participation-success or failure. Using data from an online chess platform, we find strong evidence of heterogeneous history-dependent stopping behavior. We identify two behavioral types of people: those who are more likely to stop playing after a loss and those who are more likely to stop playing after a win. We propose a behavioral dynamic choice model in which the utility from p...

摘要：This paper examines how different advertising categories are associated with attributes of brand asset recognition arising in the context of acquisitions. Prior research documents that aggregate advertising is positively associated with firm sales and brand values, but it fails to consider major recent shifts in advertising from traditional channels (such as TV) to digital advertising (such as paid search and online display). Using proprietary data, I decompose advertising expenditures into th...

摘要：Standard search models assume that consumers actively decide on the order, identity, and number of products they search. We document that online, a large fraction of searches happen in a more passive manner, with consumers merely reacting to online advertisements that do not allow them to choose the timing or the identity of products to which they will be exposed. Using a clickstream panel data set capturing full URL addresses of websites that consumers visit, we show how to detect whether a c...

摘要：We investigate an unexplored mechanism of earnings management: income shifting from not -wholly -owned subsidiaries to help the parent company avoid losses at the expense of subsidiaries. Consolidated net income attributable to the parent company (i.e., net income) increases through this mechanism, as the parent company enjoys the full amount of the shifted earnings rather than sharing them with minority investors. We design an empirical model to directly estimate the amount of income shifted ...

摘要：We develop a measure of merger and acquisition (M&A) quality using accounting theory. This measure, implied return-on-equity improvement (IRI), quantifies the minimum improvement in the target's post-acquisition return on equity (ROE) the acquirer must attain to break even on the acquisition price. Employing a large sample of M&As from 1980 to 2018, we find that a high IRI is, on average, less attainable ex post and predicts worse acquirer financial performance. The acquirer's ROE growth over ...
