Aggregation of consumer ratings: an application to Yelp.com

Because consumer reviews leverage the wisdom of the crowd, the way in which they are aggregated is a central decision faced by platforms. We explore this “rating aggregation problem” and offer a structural approach to solving it, allowing for (1) reviewers to vary in stringency and accuracy, (2) reviewers to be influenced by existing reviews, and (3) product quality to change over time. Applying this to restaurant reviews from Yelp.com, we construct an adjusted average rating and show that even a simple algorithm can lead to large information efficiency gains relative to the arithmetic average.     

Why would a big retailer refuse to collaborate on manufacturer SPIFF programs?

Big retailers that carry a large assortment of products rely on knowledgeable salespeople to provide purchase advice to customers and match customers with suitable products. Interestingly, big retailers vary in their policies regarding whether to allow their salespeople to receive manufacturer SPIFF (Sales Person Incentive Funding Formula) payments, which motivate salespeople advising at no cost of the retailer. In this study, we investigate a big retailer’s incentive to block manufacturer SPIFF programs, which has the consequence of demotivating salespeople from advising customers, from the perspective of vertical channel interactions. We scrutinize a big retailer’s decision to maximize its profit through managing its channel interactions with upstream manufacturers offering horizontally differentiated products, customers uncertain about true fits with competing products, and its salesperson who can match customers with suitable products through offering purchase advice. Our analysis shows that motivating the salesperson to advise customers is profitable for the retailer only if the such advising has moderate effectiveness in matching consumers and suitable products, and only in this case would the retailer collaborate on manufacturer SPIFF programs. Otherwise, salesperson advising hurts retailer profit and the big retailer benefits from blocking manufacturer SPIFF programs. Our study reveals the interesting theoretical insight that the incentives of a big retailer and upstream manufacturers to motivate sales advising reside in their incentives to battle for a more favorable channel status.     

Special issue introduction: Historical research on institutional change

Abstract

Both business historians and organisation studies scholars study institutional change to understand the interactions between business and society. However, research approaches differ fundamentally, with organisational research focusing on theory-driven explanations, whereas historical research is rather theory-informed. The consequence of such disciplinary orientation is that interdisciplinary conversations rarely occur. For this special issue, we invited submissions that address how historical research can contribute to our understanding of institutional change while demonstrating ‘dual integrity’ in terms of being significant pieces of historical research that provide us with new insights into historiography and at the same time addressing important theoretical concerns.     

Unraveling yields inefficient matchings: evidence from post‐season college football bowls

Many markets have “unraveled” and experienced inefficient, early, dispersed transactions, and subsequently developed institutions to delay transaction timing. It has previously proved difficult, however, to measure and identify the resulting efficiency gains. Prior to 1992, college football teams were matched for post‐season play up to several weeks before the end of the regular season. Since 1992, the market has reorganized to postpone this matching. We show that the matching of teams affects efficiency as measured by the resulting television viewership, and that the reorganization promoted more efficient matching, chiefly as a result of the increased ability of later matching to produce “championship” games.     

Estimation of variances in orthogonal finite discrete spectrum linear regression models

The Invariant Quadratic Estimators, the Maximum Likelihood Estimator (MLE) and Restricted Maximum Likelihood Estimator (REML) of variances in an orthogonal Finite Discrete Spectrum Linear Regression Model (FDSLRM) are derived and the problems of unbiasedness and consistency of these estimators are investigated.Acknowledgement.

Cultural Determinants of Household Saving Behavior

Relying on the epidemiological approach, we show that culture is a significant driver of household saving behavior. Second-generation immigrants from countries that put strong emphasis on thrift or wealth accumulation tend to save more in Germany. We confirm these results in data from the United Kingdom. By linking parents to their children, we show that these two cultural components affect the saving behavior of both first-generation immigrants and their children.     

Team Foresight in New Product Development Projects

In today’s uncertain business environments, management tools, originally designed for more stable environments, no longer serve the purpose of the organization because high levels of uncertainty make the future difficult to predict entirely. In this sense, foresight, which implies both anticipating and designing the future in a proactive manner, seems to be a rising concept. Despite growing awareness of the importance of foresight capability in terms of predicting and enacting the future, empirical research on team foresight is scant. Based on sensemaking theory, this research explores the antecedents and consequences of team foresight within the context of new product development. In studying the data from 255 new product development projects using the partial least squares structural equation modeling, this study discovers that team flexibility—in terms of operational flexibility, task autonomy and resource flexibility—is a significant antecedent of team foresight. Moreover, the results particularly emphasize that new product development teams, with a proficiency in visualizing the future through making sense of technology-, market-, and project-related information, can successfully produce new products of quality in a timely manner. Managerial and theoretical implications of the study are discussed.     

Information Asymmetry and Organizational Structure: Evidence from REITs

We test for the differences in information asymmetry across two organizational forms (external and internal) in the REIT industry. We find significant differences with external REITs being significantly more transparent relative to internal REITs, and these differences are reflected in the loan contract terms and loan syndicate structure of loans made to these two types of REITs. We find that the relatively more transparent externally advised REITs are offered more favourable loan contracts in terms of lower loan rates and lower likelihood of collateral requirement. Further, loans to external REITs have syndicates that are larger in size and the lead lender retains a smaller portion of the loan, reflecting lower information asymmetry.     

Relevance of Academic Research and Researchers' Role in the IASB's Financial Reporting Standard Setting

The International Accounting Standards Board (IASB) faces a vast number of standard‐setting issues at all levels of financial reporting. The purpose of this article is to explore the relevance of academic research for financial reporting standard setting and the role of academic researchers in the standard‐setting process. We contribute to the current debate surrounding International Financial Reporting Standards (IFRS) by drawing inferences from prior findings regarding the role of research in the IASB's standard‐setting efforts. After defining three broad categories of standard‐setting questions, we explore how the international heterogeneity of its constituency imposes constraints on the IASB's work. Then, whether and how academic research can inform policy makers is investigated from an epistemological perspective. Based on a review of extant literature, the general criteria which a piece of research should fulfil in order to be perceived as relevant and useful by standard setters are discussed. This discussion is followed by more detailed considerations regarding the suitability of different research approaches for each of the three categories of standard‐setting questions. We also touch on the subject of inferential problems inherent in most academic accounting research. Since the main objective is to contribute insights relevant to the IASB's efforts, we analyse academics' career systems and their incentives to engage in research intermediation, before discussing possible ways in which interested researchers can channel their insights into the IASB's standard‐setting process. Overall, the international dimension of IASB standard setting and its implications for relevant research are emphasized.     

自由现金流量创造力与违约风险——来自A股公司的经验证据

本文基于我国A股上市公司数据,研究了企业自由现金流量创造力与违约风险之间的关系。研究发现：(1)企业自由现金流量创造力越强,其违约风险越低。经过一系列稳健性检验后,该结论依旧成立。(2)自由现金流量创造力越强的企业往往有更低的债务规模、更高的资产收益率和更低的股票波动,因而其违约风险更低。(3)自由现金流量创造力与违约风险的负相关关系,主要存在于货币政策紧缩时期以及外部信息环境较差的企业。本文发现意味着,监管部门和投资者应重视上市公司自由现金流量创造力不足所带来的潜在债务违约风险,通过不断提高公司自由现金流量创造力,助力我国宏观经济与微观企业高质量发展。
