摘要：Existing rivalry research finds that people try harder and perform better when competing against their rivals. However, are there conditions under which rivalry can harm performance? We integrate rivalry theory with regulatory fit theory to propose two moderators of rivalry: individual skill and situational risk for status change. We test our predictions using data from software programming contests involving more than 4.6 million competitive encounters across 16,846 software developers (coder...

摘要：We examine the impact of COVID-19 on market volatility in an equilibrium framework. The model combines beliefs-dependent preferences for economic dynamics and a stochastic Susceptible-Exposed-Infectious-Recovered-Deceased (SEIRD) model with unpredictable birth/vaccine events and mitigating policies for disease propagation. The estimated model explains the realized trajectories of the S&P 500 volatility and number of new cases and identifies the source and composition of the volatility spike wh...

摘要：Financial statement preparers frequently trade off the benefit of reporting biased estimates with potential penalties for misreporting. In making this trade-off, preparers often face uncertainty about potential changes to accounting standards (standard-setting uncertainty) that could affect the future benefits of biased reporting. Our experiment documents two novel behavioral effects of standard-setting uncertainty on preparers' estimates. First, standardsetting uncertainty causes preparers to...

摘要：In many operations management problems, we need to make decisions sequentially to minimize the cost, satisfying certain constraints. One modeling approach to such problems is the constrained Markov decision process (CMDP). In this work, we develop a data-driven primal-dual algorithm to solve CMDPs. Our approach alternatively applies regularized policy iteration to improve the policy and subgradient ascent to maintain the constraints. Under mild regularity conditions, we show that the algorithm...

摘要：We show how integrated fleet and demand control can be effectively used to benefit all stakeholders in on-demand restaurant meal delivery. Fleet control-that is, the assignment of orders to couriers-is the main control mechanism to steer delivery operations. Another, mostly overlooked, control mechanism is demand control via display optimization-that is, the ordering of restaurants' display positions on the meal delivery platform. Based on historical customer interactions with a meal delivery ...

摘要：Firms increasingly use a combination of image and text description when displaying products and engaging consumers. Existing research has examined consumers' response to text and image stimuli separately but has yet to systematically consider how the semantic relationship between image and text impacts consumer choice. In this research, we conduct a series of multimethod empirical studies to examine the congruence between image- and text-based product representation. First, we propose a deep-l...

摘要：Fund companies regularly send shareholder letters to their investors. We use textual analysis to investigate whether these letters' writing style influences fund flows and whether it predicts performance and investment styles. Fund investors react to the tone and content of shareholder letters: a less negative tone leads to higher net flows. Thus, fund companies can use shareholder letters as a tactical instrument to influence flows. However, at the same time, a dishonest communication that is...

摘要：Revenue management decisions often involve both offline and online decisions. Offline decisions are made first and establish the broad and long-term operational context in which online decisions are frequently and repeatedly made, often in real time. We consider a joint optimization of offline and online decisions. Specifically, we examine a setting in which the offline decision concerns the selection of product-design characteristics (e.g., price, capacity, return eligibility, and other chara...

摘要：We estimate the size of the likely unofficial income of the government official household by assessing the difference between the income necessary to explain their observed home purchase behavior and the official income. Using unique and comprehensive House Provident Fund and home purchases data between 2006 and 2013 in a large Chinese city, we reach three conclusions. First, an average official's unofficial income is 83% of her official income; this percentage increases sharply with the offic...

摘要：Amid the rise of the influencer economy, fake social media accounts have become prevalent on many social media platforms. Yet the problem of fake accounts is still poorly understood, and so is the effectiveness of coping strategies. This research models the ecosystem of fake accounts in an influencer economy and obtains insights on fake account purchasing behaviors, the impact of antifake efforts, and the roles of various contextual factors. We show that as the antifake effort increases, the e...
