摘要：In this paper, we propose a diffusion model for a subscription service. The evolution over time of the number of subscribers is governed by a differential equation combining two processes-namely, a customer acquisition process and a customer attrition process. Assuming profit-maximization behavior of the firm, we use dynamic programming to optimize the customer equity and determine optimal customer relationship marketing expenditures. We implement an augmented Kalman filter with continuous sta...

摘要：Electronic health records (EHR) are often presumed to reduce the significant and accelerating healthcare costs in the United States. However, evidence on the relationship between EHR adoption and costs is mixed, leading to skepticism about the effectiveness of EHR in decreasing costs. We argue that simply looking at the hospital-level effects can be misleading because the benefits of EHR can go beyond the adopting hospital by creating regional spillovers via information and patient sharing. Wh...

摘要：Previous research has documented a behavioral distinction between social risk, or risk caused by human factors, and natural risk. In particular, people tend to demand a premium on the probability of a favorable outcome in order to expose themselves to a social source of risk rather than a natural source of risk. Several explanations for what drives this social risk premium have been offered-most prominently, (i) an aversion to a counterparty's potentially malign intentions and (ii) a more gene...

摘要：This study examines analyst information intermediary roles using a textual analysis of analyst reports and corporate disclosures. We employ a topic modeling methodology from computational linguistic research to compare the thematic content of a large sample of analyst reports issued promptly after earnings conference calls with the content of the calls themselves. We show that analysts discuss exclusive topics beyond those from conference calls and interpret topics from conference calls. In ad...

摘要：We examine why buy-side analysts share investment ideas on SumZero.com , a private social networking website designed to facilitate interaction and information sharing among buy-side professionals. We explore labor market motivations for information sharing and document that analysts with strong incentives to build a reputation (i.e., those who did not attend a top 10 university and those employed at small funds) are significantly more likely to share recommendations. Our findings indicate tha...

摘要：Proxy advisory firms wield large influence with voting shareholders. However, conflicts of interest may arise when an advisor sells services to both investors and issuers. Using a unique data set on voting recommendations, I find that for most types of proposals, competition from a new entrant reduces favoritism toward management by an incumbent advisor that serves both corporations and investors. The results are not driven by factors that influence the entrant's coverage decision, such as the...

摘要：We study threshold discounting, or the practice of offering a discounted-price service if at least a prespecified number of customers signal interest in it, as pioneered by Groupon. We model a capacity-constrained firm, a random-sized population of strategic customers, a desirable hot period, and a less desirable slow period. Compared to a more traditional approach (slow period discounting or closure), threshold discounting has two operational advantages. First, the contingent discount tempora...

摘要：The new perspective emerging from strategy's value-capture stream is that the effects of competition are twofold: competition for an agent bounds its performance from below, while that for its transaction partners bounds from above. Thus, assessing the intensity of competition on either side is essential to understanding firm performance. Yet, the literature provides no formal notion of competitive intensity with which to make such assessments. Rather, some authors use added value as their cen...

摘要：Many empirical studies focusing on how prior outcomes affect subsequent risk taking report conclusions that appear mutually contradictory. While some studies document increased risk taking after gains and risk aversion after losses, others report the opposite. This paper contributes to this literature by investigating horse race bettors' sequential risky decisions using individual-level data. A horse race betting market is a laboratory-like environment and can be used to analyze behavioral pat...

摘要：Regulatory agencies, auditing firms, and supply chain partners externally promote change in firms. To this end, they commonly employ two different and somewhat contradictory intervention approaches. One approach uses punitive tactics to coerce firms to change, while the other approach uses supportive tactics to encourage change. Using the context of government agencies promoting environmental improvements in firms, we examine whether such punitive (e.g., regulatory inspections with possible sa...
