This study attempted to identify the relationship among user demand for online music, unauthorized file-sharing activities (piracy), and the effect of digital rights management (DRM) in Korea. Empirical analysis showed that piracy and DRM have negative effects on the demand for online music. In...

Just as standards wars over formats had characterized VCRs upon introduction to the market, the next-generation DVD standards war between Blu-Ray and HD-DVD lasted six years before Blu-Ray won the contest. Beginning with stated preference data drawn from a structured conjoint survey conducted...

This paper investigates the impact of determination of an original initiator of transmission on demand as well as profits of the providers. For that purpose we present a new model, called differentiated traffic-based interconnection agreement (DTIA) that differentiates traffic into two types,...

Cost allocation between interconnected networks is based on measured traffic flows. This principle, however, does not provide a fair way for sharing costs. In this paper, a new bilateral model, called Differentiated Traffic-based Interconnection Agreement (DTIA) for intercarrier compensation is...

Social networks play an increasingly important role in knowledge management, information retrieval, and collaboration. In order to leverage the full potential of social networks, social networks need to be supported through technical systems. Within this paper, we introduce such a technical...

In terms of intercarrier compensation traffic flows are measured to allocate the costs between networks. This method provides a poor basis for sharing any costs. In this work we analyze the benefits of the traffic differentiation on the interconnection charges in unilateral and bilateral...

Research into computing resource markets has mainly considered the question of which market mechanism provides a fair resource allocation. It has not been discussed how a large variety of resource types influences the liquidity of resources in the market. Markets containing large numbers of...

This paper addresses the inter-provider costs sharing issue by exploring the effect of the traffic differentiation on the interconnection payments. In particular, we determine an original initiator of a transmission by means of traffic differentiation into two types, referred to as native and...

Based on the promising developments in Cloud Computing technologies in recent years, commercial computing resource services (e.g. Amazon EC2) or software-as-a-service offerings (e.g. Salesforce.com) came into existence. However, the relatively weak business exploitation, participation, and...

One of the most important properties of self-organized networks is their scale-free property. Prior research proved empirically and theoretically that scale-free networks emerge under the preferential attachment rule. However, a few empirical studies also show that empirical networks diverge...
