The Internet of Things (IoT) generates new business opportunities by connecting physical objects with a multitude of sensors. IoT research mainly focused on technology and business models are relatively unexplored, although developing IoT business models is important for successful IoT service. The existing literature on IoT business models are industry or context-dependent. The aim of this research is to develop a generic business model framework for IoT business through literature analysis and

The e-marketplace, or broker-managed online market, is one of today's most profitable e-business models. In these marketplaces, buyers routinely engage with businesses and individual sellers with whom they have had little or no prior interaction, making trust one of the most important issues in the e-marketplaces. Therefore, a clear understanding of the trust building process in the e-marketplace is important for the success in the market. In this study, we analyze the process by which e-marketp

The system ignores potential variations in the importance that patients may attach to outcomes associated with the transplant decision. For instance, some patients may prefer only kidneys that will give them a very favorable chance to achieve a successful transplant. We designed a decision model in which patients are surveyed about

Using eye-tracking field experiments, we examine the dynamics underlying consumers’ attention-allocation behaviors in online search, with focus on attention adjustment, attention renewal, and equilibrium seeking.

The findings from the two separate experiments suggest that consumers’ attention span decreases exponentially, instead of linear

Social commerce is an exciting new business model in the e-commerce world. Because it is a relatively new concept, the strategies that achieve the best market performance remain unclear. To better understand consumer purchasing behavior and develop corresponding strategies, special characteristics of social commerce need to be considered. This study uses the stimulus-organism-response framework to examine the effect of social presence and ambient factors from the impulse purchasing perspective i

Managing risk in a new product and service development process is one of the major challenges for many business managers. A scenario planning approach was incorporated into a new telecommunications service development process in order to understand the uncertainties shaping the future economic, business and technological environments. Understanding the major drivers for uncertainties helped in gaining insight and thereby generated new strategies for reducing risks and taking advantage of opportu
