CSR 2.0 — Die Kommunikation von Nachhaltigkeit in Sozialen Medien

Das Soziale Internet (Web 2.0) macht jeden potenziell zum Kommunikator — die Agenda-Setting-Funktion verlagert sich von den Massenmedien zu den Teilnehmern Sozialer Netze. Damit sehen sich Unternehmen einer zunehmend vielf?ltigen, selbstbewussten und kritischen ?ffentlichkeit gegenüber. Um Nachhaltigkeit glaubhaft zu kommunizieren, sollten Unternehmen sich daher als dialogbereiter Gespr?chspartner in Sozialen Netzen etablieren. Der vorliegende Beitrag leitet aus aktuellen Beispielen vier Spielregeln für die CSR-Kommunikation im Web 2.0 ab.     

Enterprise Mashup Systems as Platform for Situational Applications

Currently, several Enterprise 2.0 platforms are beginning to emerge. This paper introduces Enterprise Mashup technology as a means to improve IT alignment of individual work processes and changing business needs. Enterprise Mashups enable users to create customized applications to easily find and transform business information and functionalities, as well as collaboratively share pre-built Mashup applications. Therefore, the concept of Enterprise Mashups integrates Web 2.0 technologies and principles with well-established paradigms such as Enterprise Information Integration, Business Intelligence, and Business Process Management. Involved organizational key drivers, technical challenges and inhibitors are discussed to assess the potential business value and explain the emerging expansion of Mashup platforms in companies.     

Vertical Integration in the Japanese Movie Industry

This study examines vertical integration in the Japanese movie industry. I estimate an admission price equation, and a moviegoing demand equation derived from a discrete choice model of product differentiation. In order to overcome identification problems, this study exploits a panel structure dataset. My results show that the price of vertically integrated theaters tends to be higher than nonintegrated theaters, but it appears to be due to the inherent high quality of vertically integrated theaters. On the other hand, vertically integrated theaters are more popular among consumers and have higher attendance than nonintegrated theaters. Even after controlling the theater fixed effects, attendance for vertically integrated theaters is still larger than nonintegrated theaters. That is, the integration of producers/distributors and theaters is likely to be a source of economic efficiency. Policy implications are also proposed.     

Buyer Power,Transport Cost and Welfare

Manufacturers produce substitute products and sell to consumers in a linear city through competing retail stores. A low cost store obtains large market share by selling at low prices. Assume that a big retailer may exert buyer power by demanding wholesale discounts from manufacturers. The model identifies exclusionary effects of buyer power against competing retailers. It is also found that certain level of buyer power of a discount retailer may maximize social welfare, while that of a regular price retailer may maximize total consumer surplus. Nevertheless, excessive buyer power hurts both consumers and society.
