摘要:Mainstream queueing models are frequently employed in modeling healthcare delivery in a number of settings, and they further are used in making operational decisions for the same. The vast majority of these queueing models ignore the effects of delay experienced by a patient awaiting care. However, long delays may have adverse effects on patient outcomes and can potentially lead to a longer length of stay (LOS) when the patient ultimately does receive care. This work sets out to understand the...

摘要:We examine the effect of unionization on firm innovation, using a regression discontinuity design that relies on locally exogenous variation generated by elections that pass or fail by a small margin of votes. Passing a union election results in an 8.7% (12.5%) decline in patent quantity (quality) three years after the election. A reduction in R&D expenditures, reduced productivity of inventors, and departures of innovative inventors appear to be plausible underlying mechanisms through which u...

摘要:In a two-period vertical duopoly, we examine how behavior-based price discrimination (BPD) affects the firms' endogenous quality differentiation and profits. The firms' relative production efficiency, defined as the ratio between their unit cost difference and quality difference, plays a crucial role. With exogenous product qualities, BPD always decreases the profits of the more efficient firm, but increases those of the sufficiently less efficient firm. Anticipating its period 2 disadvantage ...

摘要:We study server scheduling in multiclass service systems under uncertainty in the customer arrival volumes. Common practice in such systems is to first identify staffing levels and then determine schedules for the servers that cover these levels. We propose a new stochastic integer programming (SIP) model that integrates these two decisions, which can yield lower scheduling costs by exploiting the presence of alternative server configurations that yield similar quality of service. We find that...

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:We give a method based on convex programming to calculate the optimal super-replicating and subreplicating prices and corresponding hedging portfolios of a financial derivative in terms of other financial derivatives in a discrete-time setting. Our method produces a model that matches the superreplicating (or subreplicating) price within an arbitrary precision and is consistent with the other financial derivatives prices. Applications include robust replication in terms of call prices with var...

摘要:The uncapacitated facility location (UFL) problem is one of the most famous and most studied problems in the operations research literature. Given a set of potential facility locations and a set of customers, the goal is to find a subset of facility locations to open and to allocate each customer to open facilities so that the facility opening plus customer allocation costs are minimized. In our setting, for each customer the allocation cost is assumed to be a linear or separable convex quadra...

摘要:We study a microprocessor company selling short-life-cycle products to a set of buyers that includes large consumer electronic goods manufacturers. The seller has a limited capacity for each product and negotiates with each buyer for the price. Our analysis of their sales data reveals that larger purchases do not always result in bigger discounts. Instead, the discount curve is like an N. While existing theories cannot explain this non-monotonic pattern, we develop an analytical model and show...

摘要:We study experimental coordination games to examine through which transmission channels and under which information conditions a panic-based depositor run at one bank may trigger a panic-based depositor run at another bank. We find that withdrawals at one bank trigger withdrawals at another bank by increasing players' beliefs that other depositors in their own bank will withdraw, making them more likely to withdraw as well. Observed withdrawals only affect depositors' beliefs, and are thus con...

摘要:The first in, first out (FIFO) queue discipline respects the order of arrivals, but is not efficient when customers have heterogeneous waiting costs. Priority queues, in which customers with higher waiting costs are served first, are more efficient but usually involve undesirable queue-jumping behaviors that violate bumped customers' property rights over their waiting spots. To have the best of both worlds, we propose time-trading mechanisms, in which customers who are privately informed about...
