• Building Careers in Project-Based Organizations: Breadth, Fit, and the Path to Advancement AI翻译
  作者：De Stefano, Federica; Bidwell, Matthew

  摘要：Project-based organizations allow employees in ostensibly similar roles to acquire very different experiences by working on different kinds of projects. We study how people build careers in these contexts, examining when employees choose to diversify their experience-both in terms of project content and collaborators-and how the resulting diversification affects their career advancement. Using longitudinal project data from a services organization, our results suggest that employees initially ...
• Privacy and Polarization: An Inference-Based Framework AI翻译

  摘要：Advances in behavioral targeting allow media firms to better monetize based on advertising. However, behavioral ad targeting requires consumer tracking, which has heightened privacy concerns among consumers and regulators. We examine how stricter privacy regulations that ban consumer tracking affect media firms' content strategies and ideological positioning. We consider a model where media firms choose their ideological positioning and advertising, whereas ideologically heterogeneous consumer...
• Spatial Information Sharing on On-Demand Service Platforms AI翻译

  摘要：We investigate how an on-demand service platform's mechanism to share demandsupply mismatch information spatially affects drivers' relocation decisions and the platform's matching efficiency. We consider three mechanisms motivated by practice; the platform shares demand-supply mismatch information about either zones(s) with excess demand with all drivers (surge information sharing, common practice today), all zones with all drivers (full information sharing), or zone(s) with excess demand only...
• On the Impossibility of Statistically Improving Empirical Optimization: A Second Order Stochastic Dominance Perspective AI翻译
  作者：Lam, Henry
  作者单位：Columbia University
  摘要：When the underlying probability distribution in a stochastic optimization is observed only through data, various data-driven formulations have been studied to obtain approximate optimal solutions. We show that no such formulations can, in a sense, theoretically improve the statistical quality of the solution obtained from empirical optimization. We argue this by proving that the first order behavior of the optimality gap against the oracle best solution, which includes both the bias and varian...
• Dynamic Portfolio Choice with Intertemporal Hedging and Transaction Costs AI翻译
  作者：Muhle-Karbe, Johannes; Sefton, James; Shi, Xiaofei

  摘要：When returns are partially predictable and trading is costly, utility-maximizing investors track a target portfolio at a constant trading speed. The target portfolio is optimal for a frictionless market, where asset returns are scaled back to account for trading costs and volatilities are adjusted to proxy the execution risk of holding assets that are costly to trade and exposed to volatile states. The trading speed solves an optimal execution problem, which describes how the legacy portfolio ...
• Human-Algorithmic Bias: Source, Evolution, and Impact AI翻译

  摘要：Prior work on human-algorithmic bias has seen difficulty in empirically identifying the underlying mechanisms of bias because in a typical one-time decision-making scenario, different mechanisms generate the same patterns of observable decisions. In this study, leveraging a unique repeat decision-making setting in a high-stakes microlending context, we aim to uncover the underlying source, evolution dynamics, and associated impacts of bias. We first develop a structural econometric model of th...
• Product Ratings and Externalities AI翻译
  作者：de Haan, Thomas; Knutsen, Magnus Vage
  作者单位：University of Bergen; BI Norwegian Business School; BI Norwegian Business School
  摘要：In this article, we investigate how information about production externalities, such as ecolabels, can be presented to create market pressure on firms to reduce these externalities. Specifically, we explore whether integrating information on externalities with consumer product ratings into a single combined rating can generate pressure to reduce externalities from all consumers, not just environmentally conscious ones. Theoretically, we demonstrate the existence of an equilibrium where produce...
• Does Q&A Boost Engagement? Health Messaging Experiments in the United States and Ghana AI翻译

  摘要：Effective information sharing is critical for the success of organizations and governments. Because information that is easy to access is more likely to be adopted, leaders often minimize friction in information delivery. However, one type of friction may increase engagement: piquing curiosity by posing relevant questions prior to sharing information. To test this, we shared identical information about COVID-19 in either question-andanswer format or via direct statements across two preregister...
• The Unequal Diffusion of Honesty and Dishonesty in Workplace Networks AI翻译
  作者：Ferrali, Romain
  作者单位：Centre National de la Recherche Scientifique (CNRS); Aix-Marseille Universite
  摘要：Honest and dishonest behaviors may both diffuse among the members of an organization. Knowing which of the two spreads faster is important because it impacts the extent to which managers will need to resort to other, potentially more costly solutions to curb dishonest behavior. Assessing empirically which of honest behavior or dishonest behavior spreads faster is challenging because this requires field measurements of social relationships and dishonest behavior of individual members, which pos...
• A Separation of Utility and Beliefs Through Betting Consistency AI翻译
  作者：Chateauneuf, Alain J.; Maccheroni, Fabio A.; Zank, Horst

  摘要：For standard preferences under uncertainty, minimal requirements are proposed to identify cardinal utility and subjective, potentially nonadditive, beliefs. This is achieved through an application of betting consistency. This preference principle says that outcome midpoints derived from preferences over bets on an event are also midpoints when elicited from bets on a different event. This consistency requirement provides a simplified elicitation tool, while it also serves as a robustness test ...
