摘要：The cities of Paris, London, Chicago, and New York (among many others) have set up bike-share systems to facilitate the use of bicycles for urban commuting. This paper estimates the impact of two facets of system performance on bike-share ridership: accessibility (how far the user must walk to reach stations) and bike-availability (the like-lihood of finding a bicycle). We obtain these estimates from a structural demand model for ridership estimated using data from the Velib' system in Paris. ...

摘要：Online e-commerce platforms, such as Amazon and Taobao, connect thousands of sellers and consumers every day. In this work, we study how such platforms should rank products displayed to consumers and utilize the top and most salient slots. We present a model that considers consumers' search costs and the externalities sellers im-pose on each other. This model allows us to study a multiobjective optimization, whose objective includes consumer and seller surplus as well as the sales revenue, and...

摘要：Anecdotal evidence suggests that counterfeiting /piracy can help create online word of mouth (WOM) and through this boost demand, but how powerful is such WOM? To answer this question, we conduct a descriptive study with some attempts to establish near causality. We estimate the impact of piracy on WOM and ultimately revenue by applying a panel data method to all movies widely released in the United States from 2015 to 2017. In identifying the effects of piracy we make inventive use of Russian...

摘要：We investigate whether personal information posted by job candidates on social media sites is sought and used by prospective U.S. employers. We create profiles for job candidates on popular social networks, manipulating information protected under U.S. laws, and submit job applications on their behalf to more than 4,000 employers. We estimate employer search activity and bias in interview callbacks. We find evidence of employers searching online for the candidates. At the national level, we fi...

摘要：Despite the prevalence and significance of walk-ins in healthcare, we know relatively little about how to plan and manage the daily operations of a healthcare facility that accepts both scheduled and walk-in patients. In this paper, we take a data-analytics approach and develop an optimization model to determine the optimal appointment schedule in the presence of potential walk-ins. Our model is the first known approach that can jointly handle general walk-in processes and heterogeneous, time-...

摘要：This paper analyzes a two-person, two-stage model of sequential exploration where both information and payoff externalities exist and tests the derived hypotheses in the laboratory. We theoretically show that, even when agents are self-interested and perfectly rational, the information externality induces an encouragement effect: a positive effect of first player exploration on the optimality of the second player exploring as well. When agents have other-regarding preferences and imperfectly o...

摘要：We examine professional connections among executives and analysts formed through overlapping historical employment. Analysts with professional connections to coverage firms have more accurate earnings forecasts and issue more informative buy and sell recommendations. These analysts are more likely to participate, be chosen first, and ask more questions during earnings conference calls and analyst/investor days. Homophily based on gender, age, and ethnicity is orthogonal to professional connect...

摘要：We explicitly derive and explore the optimal consumption and portfolio policies of a loss-averse individual who endogenously updates his or her reference level over time. We find that the individual protects current consumption by delaying painful reductions in consumption after a drop in wealth, and increasingly so with higher degrees of endogeneity. The incentive to protect current consumption is stronger with a medium wealth level than with a high or low wealth level. Furthermore, this indi...

摘要：Asset prices can be stale. We define price staleness as a lack of price adjustments yielding zero returns (i.e., zeros). The term idleness (respectively, near idleness) is, instead, used to define staleness when trading activity is absent (respectively, close to absent). Using statistical and pricing metrics, we show that zeros are a genuine economic phe-nomenon linked to the dynamics of trading volume and, therefore, liquidity. Zeros are, in general, not the result of institutional features, ...
