摘要：We examine if and how incumbent firms respond to entry and entry threats using nonprice modes of competition. Our analysis focuses on airline service quality. We find that incumbent on-time performance (OTP) actually worsens in response to entry, and even entry threats, by Southwest Airlines. Since Southwest is both a top-performing airline in OTP and a low-cost carrier (LCC), we conjecture that this response by incumbents may be due to a cost-cutting strategy that allows for intense postentry...

摘要：In this paper, motivated by existing and growing evidence on multiple macroeconomic volatilities, we extend the long-run risks model by allowing both a long-and a short-run volatility components in the evolution of economic fundamentals. With this extension, the new model not only is consistent with the volatility literature that the stock market is driven by two, rather than one, volatility factors, but also provides significant improvements in fitting various patterns, such as the size of ma...

摘要：This paper examines probabilistic selling (PS) as an inventory-management mechanism, paying special attention to the impact of the timing of product assignment to buyers of probabilistic goods. In practice, sellers tend to offer probabilistic products only after major demand uncertainty has been resolved. By deferring product assignments, a firm is able to obtain more information about demand for each specific product before deciding which product to assign to consumers. However, our analysis ...

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...

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：In this paper, we develop distribution-free models that solve the appointment sequencing and scheduling problem by assuming only moments information of job durations. We show that our min-max appointment scheduling models, which minimize the worst-case expected waiting and overtime costs out of all probability distributions with the given marginal moments, can be exactly formulated as tractable conic programs. These formulations are obtained by exploiting hidden convexity of the problem. In th...

摘要：We correlate competitive bidding and profits in symmetric independent private value first-price auctions with salivary testosterone, estradiol, progesterone, and cortisol in more than 200 subjects. Bids are significantly positively correlated and profits are significantly negatively correlated with basal salivary progesterone, but only for females who do not use hormonal contraceptives. Surprisingly, we have null findings for basal testosterone, estradiol, and cortisol for both males and femal...
