摘要：Even if algorithms make better predictions than humans on average, humans may sometimes have private information that an algorithm does not have access to that can improve performance. How can we help humans effectively use and adjust recommendations made by algorithms in such situations? When deciding whether and how to override an algorithm's recommendations, we hypothesize that people are biased toward following na & iuml;ve advice-weighting (NAW) behavior; they take a weighted average betw...

摘要：Social media platforms are popular for advertisers to promote products to their audience via posts. Developing these posts with the appropriate number of image features is essential as these features enhance informativeness and visual complexity, impacting how users engage with posts. However, the existing literature offers a limited investigation into this topic, primarily examining low-level imagery information while overlooking high-level image features, cross-platform differences arising f...

摘要：We model auditor switching through a tender process involving an incumbent auditor, who has private information about the client firm's audit cost (driven by audit complexity or audit risk), and an uninformed prospective auditor. When a firm's audit cost is high, the auditor is more susceptible to audit failure by erroneously attesting to the firm's favorable report. We show that, in equilibrium, the client facing a high audit cost is more likely to switch to a prospective auditor because of t...

摘要：Recession risk fluctuates substantially before the storm, yet little is known about how firms of different sizes adapt their policies accordingly. We embed timevarying recession risk into a model of liquidity management and investment, allowing firms to time their precautionary policies. Estimation reveals that small firms are less sensitive than large firms in their issuance, payout, and investment strategies to variations in recession risk. This is because small firms proactively build large...

摘要：Shipping experience improvement has been an essential business strategy in e-commerce. Beyond investing directly in improving shipping speed, online retailers have recently expanded their focus on other shipping strategies, such as offering consumers the option to pick up orders at a local station. This paper uses the opening of hundreds of such pickup stations as a natural experiment to study the impact of these stations on consumers. We find that the introduction of pickup stations increased...

摘要：We consider a multiclass queueing model of a telephone call center in which a system manager dynamically allocates available servers to customer calls. Calls can terminate through either service completion or customer abandonment, and the manager strives to minimize the expected total of holding costs plus abandonment costs over a finite horizon. Focusing on the Halfin-Whitt heavy traffic regime, we derive an approximating diffusion control problem and, building on earlier work by Beck et al. ...

摘要：We introduce a new approach for prudent risk evaluation based on stochastic dominance, and it is called the model aggregation (MA) approach. In contrast to the classic worst case risk (WR) approach, the MA approach produces not only a robust value of risk evaluation but also a robust distributional model, independent of any specific risk measure. The MA risk evaluation can be computed through explicit formulas in the lattice theory of stochastic dominance, and under some standard assumptions, ...

摘要：This paper studies the impact of information processing and learning about expected future cashflows on the level and timing of risk premiums in the cross section of firms. Learning with information sources of different qualities endogenously generates value firms, growth firms, and a value premium in equilibrium. Furthermore, the learning model predicts an upward-sloping equity term structure for value firms and a flat equity term structure for growth firms. Using earnings, return, and news d...

摘要：This paper, inspired by a collaboration with a leading consumer electronics retailer in the Middle East, explores the challenge of demand learning and pricing using separable demand models. The data scarcity issue, characterized by limited price changes and low sales volumes, renders traditional models ineffective in deriving reasonable price elasticity. To address this issue, we advocate a separable model that leverages two submodels to distinctly capture the effects of price and contextual i...

摘要：Limit orders submitted around the same time are subject to random latencies and will be queued accordingly. In equilibrium, end-of-queue limit orders always lose money-the liquidity supply appears excessive. The model generates empirical predictions regarding such overshooting liquidity: (i) new limit orders appear fleeting-clustered submissions are followed by immediate cancellations, (ii) the resulting cancel-to-add count ratio reflects adverse selection, and (iii) the cancel-to-add size rat...
