摘要：The fixed charge transportation problem generalizes the well-known transportation problem where the cost of sending goods from a source to a sink is composed of a fixed cost and a continuous cost proportional to the amount of goods sent. In this paper, we describe a new integer programming formulation with exponentially many variables corresponding to all possible flow patterns to sinks. We show that the linear relaxation of the new formulation is tighter than that of the standard mixed intege...

摘要：In this paper we examine individuals' attitudes toward the timing of information. We test a theoretical prediction that people prefer to get information clumped together rather than piecewise. We conduct a controlled lab experiment where subjects participate in a lottery and can choose between different resolutions of uncertainty (clumped or piecewise) and analyze which kind of resolution is preferred. Two additional treatments allow us to get a quantitative measure of subjects' preferences ov...

摘要：We analyze the implications of consumer privacy for competition in the marketplace. Firms compete for consumer information and derive revenues both from consumer purchases as well as from disclosing consumer information in a secondary market. Consumers choose which firm to patronize and how much personal information to provide it with. We show that firms maximize profits by focusing on a single revenue source and competing at the extensive rather than the intensive margin, outperforming compet...

摘要：I analyze a firm making a decision whether to expose itself to risk in an exogenous parameter when the firm can change a choice variable after observing the realization of the exogenous parameter. For example, the firm decides whether to choose an advertising campaign with a less certain outcome (conditional on the same expected outcome) when it can adjust the product's price after seeing the effects of the campaign. I show that in many cases, the firm wants to expose itself to risk, and I out...

摘要：We provide an empirical and theoretical assessment of the value of information sharing in a two-stage supply chain. The value of downstream sales information to the upstream firm stems from improving upstream order fulfillment forecast accuracy. Such an improvement can lead to lower safety stock and better service. Based on the data collected from a consumer packaged goods company, we empirically show that, if the company includes the downstream sales data to forecast orders, the improvement i...

摘要：In this paper we build a theoretical model of a firm repurchasing its corporate debt. We find that firm creditors as a group sell debt to the firm only at face value. However, because of the cross-creditor externalities, buying back debt is cheaper and easier when there are many creditors, e.g., when debt is traded on the open market. We further show that repurchases contribute to flexibility in firms' capital structure and can increase ex ante firm value. The value of repurchases to the share...

摘要：We implement a gym-attendance incentive intervention and elicit subjects' predictions of their postintervention attendance. We find that subjects greatly overpredict future attendance, which we interpret as evidence of partial naivete with respect to present bias. We find a significant postintervention attendance increase, which we interpret as habit formation, and which subjects appear not to predict ex ante. These results are consistent with a model of projection bias with respect to habit f...

摘要：We conduct an empirical investigation of the impact of queue management on patients' average wait time and length of stay (LOS). Using an emergency department's (ED) patient-level data from 2007 to 2010, we find that patients' average wait time and LOS are longer when physicians are assigned patients under a pooled queuing system with a fairness constraint compared to a dedicated queuing system with the same fairness constraint. Using a difference-in-differences approach, we find the dedicated...

摘要：Current branding literature investigates the spillover effects and extension effects due to the introduction of product extensions. However, no study so far has evaluated the aggregate market impact of these effects across different brand development strategies or accounted for the strategic decision to introduce the extension. It is important to examine the above given the significant investments and the high failure rates associated with the introduction of new product extensions. In this st...

摘要：When senior managers make the critical decision of whether to assign resources to a strategic initiative, they have less precise initiative-specific information than project managers who execute such initiatives. Senior management chooses between a decision process that dictates the resource level ( top-down) and one that delegates the resource decision and gives up control in favor of more precise information ( bottom-up). We investigate this choice and vary the amount of information asymmetr...
