Understanding evolutionary processes in non-manufacturing industries: Empirical insights from the shakeout in pharmaceutical wholesaling

Although the empirical pattern of industry shakeout has been documented for many manufacturing industries, we know little about the processes by which market structure evolves in non-manufacturing service industries. This paper establishes detailed empirical observations about the consolidation of a single non-manufacturing industry, the wholesale distribution of pharmaceuticals. These observations are used to explore differences between manufacturing and wholesaling in both the patterns and explanations for consolidation and analyze the explanatory power of theories that link consolidation to technological change. The analysis demonstrates that theories developed to explain consolidation in new manufacturing industries have varying degrees of applicability to the consolidation of drug wholesaling. The observed patterns of exit, innovation, and growth suggest important modifications to evolutionary theories of market structure.     

LGB-BAG模型在P2P网贷借款者信用风险评估中的应用

立足于P2P平台,利用P2P平台个人借款人的信息建立了一套系统的信用风险评估指标体系来甄别可能违约的借款人。本文基于LightGBM（一种基于决策树的Boosting模型）和Bagging而提出一种新的LGB-BAG模型,有效结合了Boosting和Bagging的优势。结果表明,在N增大到一定程度的时候,LGB-BAG的F1均值（预测效果）要高于LightGBM和随机森林;并且LGB-BAG的F1方差也要小于其余两种模型。LGB-BAG的F1均值最高可达到0.71175,且LGB-BAG模型能够显著提高信用风险预测效率。     

Deane–Draper stores: employee empowerment in a retail environment

This case focuses on the application of employee empowerment principles to a large retail group. It provides the opportunity to analyse the manner of the strategy implementation and the consequent impact on both individuals and the organization. The case establishes significant financial underperformance in one part of a retail group and investigates the use of ‘employee empowerment’ techniques - following Carlzon (1987) - to provide a solution. The case illustrates the dysfunctional activity associated with implementing empowerment without either appropriate management control or staff training, together with the dire financial implications. The Teaching Resource Note discusses alternative approaches that might have been adopted.     

Using the economics of platforms to understand the broadband-based market formation in the New Zealand Ultra-Fast Broadband Network

The government of New Zealand is currently building a nation-wide fibre-optics network, a project known as the Ultra-Fast Broadband (UFB) initiative. The UFB network will cover 75 percent of New Zealanders over 10 years and will cost NZD $1.5 billion to the New Zealand government. The technical and economic characteristics of the new network will have a deep impact on the current landscape of the telecommunications markets. Institutional arrangements are in place for the development of the New Zealand's UFB: a government-owned agency, Crown Fibre Holdings (CFH); private investors who jointly with CFH own the Local Fibre Companies (LFCs) which will operate the UFB; and Retail Service Providers (RSP) that will provide end-user services by purchasing wholesale services to the LFCs. Relying on a normative economics approach that uses recent advances in the theory of platform-based markets with cross-network effects – also known as theory of two-sided platforms – the paper proposes a novel view of the way markets over the UFB will unfold. On one hand, the theory is used to explain the rationale behind regulatory decisions already made and their effect on the development of UFB-based markets for contents and services. Such analysis is followed, on the other hand, by the introduction of a simple taxonomy for the RSPs which provides the framework to argue about the most likely scenarios for service deployment and competition to develop over the UFB. The analytical framework reveals that the UFB ecosystem will be fraught with cross-network externalities which are the basis for regulatory decisions already adopted and the source of particular forms of strategic behavior adopted by the UFB-based market innovators.     

Risk averse retail pricing with robust demand forecasting

Good demand estimates are the key to effective pricing decision-making. However, they are subject to a high degree of uncertainty due to various factors that are unpredictable or difficult to model, thus making pricing decisions risky. This research provides a simple proposal for a robust optimization methodology that incorporates both demand uncertainty and the decision maker's degree of risk aversion. Uncertainty is explicitly considered for two coefficients of a linear demand function, price expressions are derived, and a criterion is proposed for defining the degree of risk aversion. The resulting model is also applied to an exponential demand case to better reflect a more realistic retail setting.     

Crowdfunding: The collaborative economy for channelling institutional and household savings

The financial disintermediation mechanism known as “loan-based-crowdfunding” has recently come under regulation in several countries. This competitive investment and finance vehicle is already well established in the US and British markets.By compiling empirical data from a reference crowdfunding platform, this article compares loan-based crowdfunding with traditional investment vehicles such as investment funds, equities or pension funds.The conclusion of the study is that saving through crowdfunding allows the optimization of a portfolio comprising both institutional and retail investors.     

A logit model of retail investors' individual trading decisions and their relations to insider trades

Among the various external information sources that influence individual investors' trading decisions, no research has considered the important influence of insiders' transactions. Retail investors might copy the behavior demonstrated by insiders' trading; therefore, this study establishes an approach to estimate the buying probability for a certain stock by a certain investor at a certain point in time and analyzes whether insider trade reports influence this probability. Using a sample of more than 270,000 retail trades in Germany between 2008 and 2009, along with more than 3000 insider trades in the same period, we find evidence of copying of insiders' trades by retail investors. The basic mimicry hypothesis holds, even when we consider an information event hypothesis and an insider attention effect hypothesis as alternative explanations. A robustness test also supports the findings.     

The shipping strategies of internet retailers: Evidence from internet book retailing

Managing the shipment of goods to consumers is one of the central aspects of retail competition on the internet. In this article, we analyze internet retailers’ shipping strategies using data from the internet book retailing industry. We find that, controlling for a variety of observable firm characteristics, firms with lower product prices offer lower shipping fees and higher quality shipping in terms of average delivery time, compared to firms with higher product prices. These patterns cannot be readily reconciled with a large class of models of competition under perfect consumer information. Theories based on imperfect consumer information can explain the findings better.

Store Manager–Store Performance Relationship: A Research Note

Despite the critical role that store managers play in linking top management teams and service/retail employees, as well as in fulfilling corporate strategy within chain store environments, service management research infrequently addresses the factors that may promote store managers’ effective exchange relationships within the firm and subsequent effects on store operations and profitability. This study focuses on how store managers’ performance orientation, trust of a regional manager’s capabilities, and organizational commitment affect a manager’s relationships relative to regional managers and frontline employees. The direct effect of store managers’ relationship capacity on store performance is also examined. The results, based on survey data from managers of stores of a retail and service chain and company financial reports, generally support the suggested hypotheses. Specifically, a store manager’s relationship with his/her supervisor has a strong influence on how the manager views the supervisor’s leadership support and leadership style, which ultimately influence store performance (primary goods/service sales and store profits).     

How digital platforms influence luxury purchase behavior in India?

In an emerging country such as India, consumers are tech savvy and connect easily with digital media platforms. They use these platforms even for luxury purchases. However, there have been only a few conceptual papers on this process. Therefore, this study aims to explain how digital platforms influence consumers’ decision for luxury brands in India. Two qualitative studies were conducted with young Indian consumers as they are the heaviest users of digital platforms and the most frequent purchasers of luxury brands. The first study consisted of 156 respondents in 15 focus groups in four major Indian cities. The second was made up of 95 on-site customer observations in 18 retail luxury stores and 45 consumers’ interviews. These data were further validated by 32 interviews with luxury brand managers and retail managers We found and developed a cyclical framework that projects digital media influences on Indian consumers at all the phases of purchase, i.e., pre-purchase is digital and hedonic, purchase is experiential and enjoyable while digital media is used and post-purchase is based on aspirations, lifestyles and virtual networks. More importantly, these consumers are always connected to reference groups digitally who significantly affect their purchase behavior and subsequent brand choices.
