A typology of Indian hypermarket shoppers based on shopping motivation

Abstract: Purpose – Hypermarket is the most successful amongst organised retail formats in India. The purpose of this paper is to identify segments of hypermarket shoppers based on shopping motivation. The study profiles the identified segments on demographic characteristics and shopping outcomes, and compares the shopping motivation of hypermarket consumers with that of traditional store shoppers. Design/methodology/approach – The study involved a survey of 201 actual shoppers in a hypermarket and that of 117 actual shoppers in 20 traditional stores. Principal components analysis of the motives for shopping at hypermarket and traditional store identified the respective dimensions of shopping motivation. Cluster analysis of the factor scores obtained on shopping motivation at hypermarket revealed the typology of hypermarket shoppers. Chi-square test and MANOVA were used to profile the identified segments of hypermarket shoppers on demographic characteristics and shopping outcomes respectively. Findings – Results re...

Supply Chain Finance enabled early pay: unlocking trapped value in B2B logistics

Abstract: Recent breakthroughs in Business-to-Business (B2B) trade have opened new avenues for value creation in the financial supply chains. Based on supply chain event triggers, innovative financing is being provided at different points of the supply chains. This new phenomenon, termed as Supply Chain Finance (SCF), is transforming Working Capital Management (WCM). In this study we focus on payables management of a buying firm in a supply chain with SCF enabled early payment program in place. A stochastic dynamic programming model is developed and the value of SCF enabled early payment program under varying future cash-flows are ascertained through extensive numerical analysis.

MARP: A Multi-Agent Routing Protocol for Mobile Wireless Ad Hoc Networks

Abstract: Supporting mobility in a multi hop wireless environment like the MANET still remains a point of research, especially in the context of time-constrained applications. The incapacity of ad hoc networks to offer services of the likes of static or infratructured networks may be attributed to two major reasons. One, unpredictable mobility of hosts cause location-transparent-packet-delivery to be implemented only at the expense of large control overhead. Two, the lack of central control causes connection management and scalability to be major problems in the multi hop environment. In this paper we propose an efficient agent based routing mechanism that not only incurs minimal overhead, but also lays the foundation for additional functionalities as network management and real time applications. In other words, we show that the agent framework makes the MANET robust and survivable under stringent system constraints.

Adoption of identity theft countermeasures and its short- and long-term impact on firm value

Abstract: Identity theft has impaired e-commerce. To combat the crime, many identity theft countermeasures (ITC) have been proposed. As investments in ITC are substantial and the benefits of such investments are intangible, companies are often hesitant to adopt such measures. This was the motivation for this study of the impact of 526 ITC adoption announcements on short- and long-term market value. The event study shows that such announcements result in positive market return of about U.S. $583 million around the date of announcement. Calendar-time portfolio analysis (CPA) is used for the long-term impact analysis and shows that the adoption of ITC generates positive and significant average monthly return up to 1.5% with control of market risk factors in a year. Subsampling analysis and interaction analysis show that U.S. listing, early ITC adoption, and two- factor authentication may moderate the market value of ITC adopters differently. A number of robustness checks (e.g., Heckman model, cross-sectional regression on Tobin’s Q, firm-specific risk factor analysis, subsampling analysis by ICT development, and analysis of security statements in annual reports) are performed. The research provides quantitative evidence of financial gain resulting from adoption of ITC and aspires to raise ITC awareness among industrial practitioners.
