This ISeB special issue on e-business reflects a selected set of high-quality papers presented in the Sixth International Workshop on e-Business (WeB) held in Montreal, Canada on 9 December 2007. WeB 2007, sponsored by the AIS Special Interest Group on E-Business, was an ancillary workshop of the International Conference on Information Systems (ICIS). The papers in this special issue demonstrat...

a r t i c l e i n f o Electronic supply chain management (e-SCM), a specific form of inter-organizational systems, has generally regarded as one of the major strategies to create competitive advantage. The diffusion of e-SCM among trading partners is critical for its final successful use and accordingly, performance impact. However, the diffusion process is complex and dynamic in nature and inv...

RFId adoption process is receiving a lot of attention in literature; studies assessing its potentials in supply chains are now well documented. Despite this rising interest, the diffusion pattern of RFId systems in the vertical supply chains has been only scarcely addressed and theoretical contributions explaining dynamics and drivers are still missing. This study shows that the Diffusion of In...

To survive in today’s global marketplace, businesses need to be able to deliver products on time, maintain market credibility and introduce new products and services faster than competitors. This is especially crucial to the Smalland Medium-sized Enterprises (SMEs). Since the emergence of the Internet, it has allowed SMEs to compete effectively and efficiently in both domestic and international...

This paper attempts to explain why innovating firms often fail to obtain significant economic returns from an innovation, while customers, imitators and other industry participants benefit. Business strategy particularly as it relates to the firm’s decision to integrate and collaborate is shown to be an important factor. The paper demonstrates that when imitation is easy, markets don’t work wel...

We consider a processor sharing queue where the number of jobs served at any time is limited to K, with the excess jobs waiting in a buffer. We use random counting measures on the positive axis to model this system. The limit of this measure-valued process is obtained under diffusion scaling and heavy traffic conditions. As a consequence, the limit of the system size process is proved to be a p...

We model the diffusion of IT outsourcing via announcements about IT outsourcing deals. We estimate a lognormal diffusion curve to test whether IT outsourcing follows a pure diffusion process or there are contagion effects involved. The methodology permits us to study the consequences of outsourcing events, especially mega-deals with IT contract amounts that exceeded US$ 1 billion. Mega-deals ac...

Abstract. In this paper, we study the asymptotic properties of the Hayashi-Yoshida estimator, hereafter HY-estimator, of two diffusion processes when observations are subject to non-synchronicity. Our setup includes random sampling schemes, provided that the observation times are independent of the underlying diffusions. We first derive second-order asymptotic expansions for the distribution of...
