摘要:There are over 90,000 patients in the United States waiting for a kidney transplant. Under the current allocation policy, the vast majority of deceased organs are allocated locally. This causes significant disparities in waiting times and access to transplant across different geographical areas. To ameliorate this inequity, we propose an operational solution that offers affordable jet services (OrganJet) to patients on the transplant waiting list, allowing them to list in multiple different, a...

摘要:We introduce an equity-credit portfolio framework taking into account the structural interaction of market and credit risk, along with their systemic dependencies. We derive an explicit expression for the optimal investment strategy in stocks and credit default swaps (CDSs). We exploit its representation structure and analyze the mechanisms driving the optimal investment decisions. The transmission of market risk premia is the key mechanism through which systemic influences affect the optimal ...

摘要:This paper shows that managers are influenced by their social peers when making corporate policy decisions. Using biographical information about executives and directors of U.S. public companies, we define social ties from current and past employment, education, and other activities. We find that more connections two companies share with each other, more similar their capital investments are. To address endogeneity concerns, we find that companies invest less similarly when an individual conne...

摘要:There is an increasing attention in information systems to be able to predict outcomes using search frequency on popular portals. This growing literature focuses on revealing demand patterns of individual assets (e.g., products, stocks, services). However, users typically search many different assets together (e.g., correlated searches) and leave a digital footprint, which can help provide insights on the behaviors of a group of assets. Furthermore, such group behavior can be used to predict o...

摘要:Using golf play as a measure of leisure, we provide direct evidence that some CEOs shirk their responsibilities to the detriment of firm shareholders. CEOs with lower equity-based incentives play more golf and those that golf the most are associated with firms that have lower operating performance and firm values. Numerous tests accounting for the possible endogenous nature of these relations support a conclusion that CEO shirking causes lower firm performance. New CEOs and those at firms with...

摘要:It has been argued that servicizing business models, under which a firm sells the use of a product rather than the product itself, are environmentally beneficial. The main arguments are as follow. First, under servicizing the firm charges customers based on the product usage. Second, the quantity of products required to meet customer needs may be smaller because the firm may be able to pool customer needs. Third, the firm may have an incentive to offer products with higher efficiency. Motivate...

摘要:We explore analysts' earnings forecast data to improve on one popular disagreement measure-the analyst forecast dispersion measure-proposed by Diether et al. [Diether KB, Malloy CJ, Scherbina A (2002) Differences of opinion and the cross section of stock returns. J. Finance 57: 2113-2141]. Our analysis suggests that changes in the standard deviations of forecasted earnings can work as a complementary disagreement measure that is comparable across stocks and immune from other return-predictive ...

摘要:Many online content providers aim to compensate for a loss in advertising revenues by charging consumers for access to content. However, such a choice is not straightforward because subscription fees typically deter customers, and a resulting decline in viewership further reduces advertising revenues. This research examines whether firms that offer both free and paid content can benefit from adjusting the amount of content offered for free. We find that firms should offer more free-and not pai...

摘要:Different models of uncertainty aversion imply strikingly different economic behavior. The key to understanding these differences lies in the dichotomy between first-order and second-order ambiguity aversion, which I define here. My definition and its characterization are independent of specific representations of decisions under uncertainty. I showthat with second-order ambiguity aversion, a positive exposure to ambiguity is optimal if and only if there is a subjective belief such that the ac...

摘要:Many service systems use case managers, servers who are assigned multiple customers and have frequent, repeated interactions with each customer until the customer's service is completed. Examples may be found in healthcare (emergency department physicians), contact centers (agents handling multiple online chats simultaneously) and social welfare agencies (social workers with multiple clients). We propose a stochastic model of a baseline case-manager system, formulate models that provide perfor...
