摘要：Recent years have witnessed the rise of queue scalping in congestion-prone service systems. A queue scalper has no material interest in the primary service but proactively enters the queue in hopes of selling his spot later. This paper develops a queueing-game-theoretic model of queue scalping and generates the following insights. First, we find that queues with either a very small or very large demand volume may be immune to scalping, whereas queues with a nonextreme demand volume may attract...

摘要：We consider a periodic-review single-product inventory system with fixed cost under censored demand. Under full demand distributional information, it is well known that the celebrated (s, S) policy is optimal. In this paper, we assume the firm does not know the demand distribution a priori and makes adaptive inventory ordering decisions in each period based only on the past sales (a.k.a. censored demand). Our performance measure is regret, which is the cost difference between a feasible learni...

摘要：This study investigates whether initial public offering (IPO) firms inflate core earnings through classification shifting (i.e., misclassifying core expenses as income-decreasing special items) immediately prior to IPOs. We provide initial evidence that IPO firms engage in classification shifting in the pre-IPO period. Using hand-collected price and share information from IPO prospectuses, we find that pre-IPO classification shifting is positively associated with a price revision from the midp...

摘要：This paper shows that decentralized supply chains, in which upstream firms use linear wholesale prices, may experience lower upstream production and downstream sales volatility than vertically integrated supply chains and may be less susceptible to the bullwhip effect by which the variance of upstream production exceeds the variance of downstream sales. The reason is that decentralized supply chains exhibit a price effect, whereby upstream producers raise wholesale prices in the case of positi...

摘要：The literature on resource allocation under adverse selection has focused on models in which the resource being allocated is such that the privately informed agent always prefers more of it to less. We analyze a firm's optimal resource allocation mechanism when this assumption does not hold and show that the resulting mechanism has a number of novel characteristics. For example, first best may be achievable even with nontrivial information asymmetry; when first best cannot be achieved, it is a...

摘要：Online communities bring together participants from diverse backgrounds and often face challenges in aggregating their opinions. We infer lessons from the experience of individual contributors to Wikipedia articles about U.S. politics. We identify two factors that cause a tendency toward moderation in collective opinion: Either biased contributors contribute less, which shifts the composition of participants, or biased contributors moderate their own views. Our findings show that shifts in the...

摘要：Diversification is a basic economic principle that helps to hedge against uncertainty. It is, therefore, intuitive that both risk aversion and ambiguity aversion should positively affect the value of diversification. In this paper, we show that this intuition (1) is true for risk aversion but (2) is not necessarily true for ambiguity aversion. We derive sufficient conditions, showing that, contrary to the economic intuition, ambiguity and ambiguity aversion may actually reduce the diversificat...

摘要：We propose a macroeconomic model in which variation in the level of trust leads to higher innovation, investment, and productivity growth. The key feature in the model is a hold-up friction in the creation of new capital. Innovators generate ideas but are inefficient at implementing them into productive capital on their own. Firms can help innovators implement their ideas efficiently but cannot ex ante commit to compensating them appropriately. Rather, firms are disciplined only by the value o...

摘要：We draw on a five-year longitudinal data set to investigate the influence of performance measurement in the processual dynamics of strategic change, particularly in enacting effective strategic change. Our model examines the role of performance measurement in driving strategy-consistent operational changes and in ensuring that the desired objectives of the strategic change process are achieved. We investigate these roles for performance measurement over time and empirically document lags betwe...

摘要：We study how institutional investor attention to a firm affects the timeliness of analysts' forecasts for that firm. We measure abnormal institutional attention (MA) using Bloomberg news search activity for the firm on earnings announcement days. We find that analysts issue more timely forecasts when AIA is high on the earnings announcement day. Analyst responsiveness to AIA is stronger when analysts have more resources and experience and weaker when the AIA of other covered firms is high. Ana...
