摘要：We consider a supply chain with one buyer and two suppliers who are subject to disruptions and whose likelihoods of disruption are their private information. In such a setting, does the buyer benefit from engaging the services of a better-informed procurement service provider (PSP) compared to procuring directly from the suppliers? Intuition might suggest that hiring a PSP is always the right choice because the PSP's knowledge of the supply base improves supplier selection and management. On t...

摘要：Statistical aggregation is often used to combine multiple opinions within a group. Such aggregates outperform individuals, including experts, in various prediction and estimation tasks. This result is attributed to the wisdom of crowds. We seek to improve the quality of such aggregates by eliminating poorly performing individuals from the crowd. We propose a new measure of contribution to assess the judges' performance relative to the group and use positive contributors to build a weighting mo...

摘要：Compensation not only provides incentives to an existing manager but also affects the type of manager attracted to the firm. This paper examines the dual incentive and sorting effects of performance pay in a simple contracting model of endogenous participation. Unless the manager is highly risk averse, sorting dampens optimal pay-performance sensitivity (PPS) because PPS beyond a nominal amount transfers unnecessary (information) rent to the manager. This helps explain why empirical estimates ...

摘要：We propose an approach for estimating customer preferences for a set of substitutable products using only sales transactions and product availability data. The underlying demand framework combines a general, nonparametric discrete choice model with a Bernoulli process of arrivals over time. The choice model is defined by a discrete probability mass function (pmf) on a set of possible preference rankings of alternatives, and it is compatible with any random utility model. An arriving customer i...

摘要：This paper investigates the effects of analyst recommendations issued after a merger announcement on deal completion. We find the probability of completion increases (decreases) with the favorability of acquirer (target) recommendations. Results from instrumental variables tests support causality running from recommendations to merger outcomes. Additional tests suggest that these relations are driven by target shareholders reassessing the merger offer in response to movements in acquirer and t...

摘要：Prior studies on performance-based contracting (PBC) for after-sales services have highlighted its advantages over traditional resource-based contracting (RBC), when products are established and their reliability is known to all parties. We develop a game theoretic model to investigate how these insights are affected when the vendor is privately informed about the reliability of a newly developed product. A novel feature of our model is the interaction between reliability signaling (private in...

摘要：Probabilistic selling-the sale of synthetic products consisting of a lottery between two distinct goods-has been extensively analyzed in horizontal markets. In this research, we investigate probabilistic selling in quality-differentiated markets. This is an important new dimension of inquiry because of the widespread prevalence of quality-differentiated markets as well as significant differences in the preference structure across these markets. In fact, this latter consideration casts doubt as...

摘要：Although individuals can derive substantial benefits from exchanging information and ideas, many individuals are reluctant to seek advice from others. We find that people are reticent to seek advice for fear of appearing incompetent. This fear, however, is misplaced. We demonstrate that individuals perceive those who seek advice as more competent than those who do not. This effect is moderated by task difficulty, advisor egocentrism, and advisor expertise. Individuals perceive those who seek a...

摘要：Advances in digital technologies have led to an increasing concern about piracy for providers of digital content (e.g., e-books, games, music, software, videos). Yet controversies exist over the influence of copyright protection on firm profitability. The objective of this paper is to provide an alternative rationale for the growing anti-protection trend and to investigate optimal copyright enforcement and quality provision in a monopoly setting. The proposed economic mechanism centers on the ...

摘要：We consider a multiperiod single product pricing problem with an unknown demand curve. The seller's objective is to adjust prices in each period so as to maximize cumulative expected revenues over a given finite time horizon; in doing so, the seller needs to resolve the tension between learning the unknown demand curve and maximizing earned revenues. The main question that we investigate is the following: How large of a revenue loss is incurred if the seller uses a simple parametric model that...
