摘要：Online product ratings offer information on product quality. Scholars have recently proposed the potential of designing multidimensional rating systems to better convey information on multiple dimensions of products. This study investigates whether and how multidimensional rating systems affect consumer satisfaction (measured by product ratings), based on both observational data and two randomized experiments. Our identification strategy of the observational study hinges on a natural experimen...

摘要：I explore the role of the just-in-time (JIT) inventory system in the increase in cash holdings by U.S. manufacturing firms. I develop a model to illustrate the mechanism through which JIT affects cash and quantify its impact. In the model, both cash and inventory can serve as working capital. As firms switch from the traditional system to JIT, they shift resources from inventory to cash to facilitate transactions with suppliers. On average, this switchover accounts for a 4.1-percentage-point i...

摘要：It is widely believed that a little flexibility added at the right place can reap significant benefits for operations. Unfortunately, despite the extensive literature on this topic, we are not aware of any general methodology that can be used to guide managers in designing sparse (i.e., slightly flexible) and yet efficient operations. We address this issue using a distributionally robust approach to model the performance of a stochastic system under different process structures. We use the dua...

摘要：Automated valuation models (AVMs) are widely used in the valuation of pools of residential mortgages. In this paper, we provide evidence that high pricing errors in human and automated valuation models as well as rejection of loans with relatively low appraisals may generate the appearance of appraisal bias even when the original appraisals are unbiased. We also present evidence that the estimated frequency of appraisal overstatement is quite sensitive to assumptions about loan denial rates du...

摘要：This study provides novel evidence that expert economic agents' work-related activities are systematically influenced by the time of day. We use archival data derived from time-stamped quarterly earnings conference calls together with linguistic algorithms to measure and track the moods of executives and analysts at different times of the day. The evidence indicates that the tone of conference call discussions deteriorates markedly over the course of the trading day, with both analysts' and ex...

摘要：The majority of extant studies involving status argue that status enters into choice and evaluation because people personally believe that status serves as a signal of quality. However, this mechanism seems less plausible in cases when consensus on the meaning of quality is lacking. To understand how and why status often nonetheless enters into evaluation in those cases, this paper contributes to a growing body of work that proposes that individuals and organizations are particularly likely to...

摘要：Firms employ various techniques to obtain information about consumer taste/location and valuation prior to making product design decisions. User-generated content has become an important information source. The vast variety and volume of user-generated content makes firms better informed about consumers (precision-improving effect), and the common and public nature of user-generated content makes firms' information more correlated (correlation-increasing effect). We examine the impact of user-...

摘要：We study how digital service firms can develop an active customer base, focusing on two questions. First, how does the way that customers use the service postadoption to meet their own needs (personal usage) and to interact with one another (social usage) vary across customer acquisition methods? Second, how do firm-to-customer and customer-to-customer communications promote different types of usage? We study these questions using two data sets and by developing a multivariate hierarchical Poi...

摘要：Firms in several industries, such as medicine, apparel, and publishing, must jointly determine the price and production quantity of their products well in advance of the selling season. Normative prescriptions to solve this problem have generally ignored behavioral aspects of decision making while behavioral research has paid limited attention to interdependent, multidimensional decisions. We experimentally examine subjects' performance when they jointly determine price and quantities. We find...
