摘要：We present a new unbiased algorithm that estimates the expected value of f(U) via Monte Carlo simulation, where U is a vector of d independent random variables, and f is a function of d variables. We assume that f does not equally depend on all its arguments. Under certain conditions, we prove that, for the same computational cost, the variance of our estimator is lower than the variance of the standard Monte Carlo estimator by a factor of order d. Our method can be used to obtain a low-varian...

摘要：Recent research has found widespread discrimination by hosts against guests of certain races in online marketplaces. In this paper, we explore ways to reduce such discrimination using online reputation systems. We conducted four randomized field experiments among 1,801 hosts on Airbnb by creating fictitious guest accounts and sending accommodation requests to them. We find that requests from guests with African American-sounding names are 19.2 percentage points less likely to be accepted than ...

摘要：In the classical secretary problem, one attempts to find the maximum of an unknown and unlearnable distribution through sequential search. In many real-world searches, however, distributions are not entirely unknown and can be learned through experience. To investigate learning in such settings, we conduct a large-scale behavioral experiment in which people search repeatedly from fixed distributions in a repeated secretary problem. In contrast to prior investigations that find no evidence for ...

摘要：Every firm has a business model, which is the collection of strategic decisions that determine how the firm generates a sustainable enterprise through the creation of enough value (its supply model) and the extraction of a sufficient portion of that value (its revenue model). Innovative business models-for example, fast fashion (e.g., Zara), e-tailing (e.g., Amazon), and ride-sharing (e.g., Uber)-are capable of offering new products and services that generate considerable consumer utility and ...

摘要：The underrepresentation of minorities in cultural industries is a widely publicized problem with far-reaching economic and social significance. It is also one of many industries in which employers suggest that the locus of bias is not within the organization but with the consumer. The empirical challenge of relating consumer behavior to employee composition has constrained prior efforts to test their claim and to test the theory of consumer discrimination more broadly. As a result, employers h...

摘要：This paper explores how prominent venture capitalists (VCs) affect chief executive officer (CEO) replacement in startups. Defining prominence using eigenvector centrality, we use matching methods and instrumental variables to show that startup CEO replacement occurs more often and faster when prominent VCs participate. We further explore these VCs' comparative advantage in managing CEO turnover, finding that the prominent VC effects increase as replacement costs rise, such as when incumbent CE...

摘要：We examine whether family firms invest more in employee relations than non-family firms. Using the variation in state-level changes in inheritance, gift, and estate taxes as an exogenous shock to family control, we find that family firms, particularly those in which a founder serves as chief executive officer or those in which a family member serves as a director on the board, treat their employees better than nonfamily firms. More importantly, family firms focus on investing in employee relat...

摘要：Many of the activities performed in firms are done by teams, where a common output is observed, but outsiders cannot observe the individual contributions of each team member. This leads to the possibility of some of the members of the team free-riding on the contributions of others. Repeated interactions of a team can then potentially lead to cooperation among the members of the team under the credible threat of returning to a free-riding equilibrium. However, repeated interaction under cooper...

摘要：Firms typically use query-based search to help consumers find information/products on their websites. We consider the problem of optimally ranking a set of results shown in response to a query. We propose a personalized ranking mechanism based on a user's search and click history. Our machine-learning framework consists of three modules: (a) feature generation, (b) normalized discounted cumulative gain-based Lambda-MART algorithm, and (c) feature selection wrapper. We deploy our framework on l...

摘要：This paper empirically examines the evaluations of 537 ventures in high-growth industries performed by 251 experienced entrepreneurs, investors, and executives. These experts evaluated ventures by reading succinct summaries of the ventures without meeting the founding teams, and their evaluations were not disclosed to the entrepreneurs. We find that experts can differentiate among early-stage ventures on grounds of quality beyond the explicit venture and entrepreneur characteristics contained ...
