摘要：We use a detailed operational and clinical data set from a maternity hospital to investigate how workload affects decisions in gatekeeper-provider systems, where the servers act as gatekeepers to specialists but may also attempt to serve customers themselves, albeit with a probability of success that is decreasing in the complexity of the customers' needs. We study the effect of workload during a service episode on gatekeepers' service configuration decisions and the rate at which gatekeepers ...

摘要：In 2008, the majority of U.S. airlines began charging for the second checked bag, and then for the first checked bag. One of the often cited reasons for this action by the airlines' executives was that this would influence customers to travel with less baggage and thus improve cost and operational performance. A popular customer belief, however, is that airline departure delays got worse due to an increase and size of customer carry-on baggage. A notable exception to the charging for checked b...

摘要：Based on a family of discrepancy functions, we derive nonparametric stochastic discount factor bounds that naturally generalize variance, entropy, and higher-moment bounds. These bounds are especially useful to identify how parameters affect pricing kernel dispersion in asset pricing models. In particular, they allow us to distinguish between models where dispersion comes mainly from skewness from models where kurtosis is the primary source of dispersion. We analyze the admissibility of disast...

摘要：Firms' innovative activities can be sensitive to public policies that affect the availability of capital. In this paper, we investigate the effects of regional and temporal variation in U.S. personal bankruptcy laws on firms' innovative activities. We find that bankruptcy laws that provide stronger debtor protection decrease the number of patents produced by small firms. Stronger debtor protection also decreases the average quality, and variance in quality, of firms' patents. We find evidence ...

摘要：We study how to optimally attract new customers using a referral program. Whenever a consumer makes a purchase, the firm gives her a link to share with friends, and every purchase coming through that link generates a referral payment. The firm chooses the referral payment function and consumers play an equilibrium in response. The optimal payment function is nonlinear and not necessarily monotonic in the number of successful referrals. If we approximate the optimal policy using a linear paymen...

摘要：In this study, we focus on measuring the efficiency of category-level sales response to promotions across various categories and stores. Our heterogeneous stochastic frontier model allows us to attribute portions of this efficiency to specific characteristics of the stores and categories. Using our full PEM (promotional efficiency frontier) model, we analyze the efficiency of 20 frequently bought categories of a supermarket retailer and apply it to store-category-level data. We find that the a...

摘要：This paper has two objectives. First, we show how debt financing distorts a retailer's inventory decision when the retailer orders multiple items that differ in cost, revenue, or demand parameters. Taking advantage of limited liability, a debt-financed retailer favors items with a low salvage value, those with a high profit margin, and those that represent a large proportion of the total inventory investment. Second, we argue that this distortion is mitigated when the financing is provided by ...

摘要：Previous research often interprets the choice to restrict one's future opportunity set as evidence for sophisticated time inconsistency. We propose an additional mechanism that may contribute to the demand for commitment technology: the desire to signal to others. We present a field experiment where participants can choose to give up money if they do not follow through with an action. When commitment choices are made public rather than kept private, we find significantly higher uptake rates.

摘要：We demonstrate that widely used measures of antigay sentiment and the size of the lesbian, gay, bisexual, and transgender (LGBT) population are misestimated, likely substantially. In a series of online experiments using a large and diverse but nonrepresentative sample, we compare estimates from the standard methodology of asking sensitive questions to measures from a veiled methodology that precludes inference about an individual but provides population estimates. The veiled method increased s...

摘要：We use a controlled experiment to analyze gender differences in stereotypes about risk preferences of men and women across two distinct island societies in the Pacific: the patrilineal Palawan in the Philippines and the matrilineal Teop in Papua New Guinea. We find no gender differences in actual risk preferences, but we find evidence for culture-specific stereotypes. Like men in Western societies, Palawan men overestimate women's actual risk aversion. By contrast, Teop men underestimate women...
