Economies Of Scope

Der First-Copy-Cost-Effekt gilt als ein zentrales Spezifikum der Medienproduktion und bezeichnet die für die Medienwirtschaft charakteristische Fixkostendegression bei steigender Ausbringungsmenge. Obwohl der First-Copy-Cost-Effekt zu den Klassikern in Lehrbüchern der Medienökonomie und des Medienmanagements gehört, bestehen Zweifel, ob er noch immer ein adäquates Abbild der Kostenstruktur der Medienproduktion darstellt. Der vorliegende Beitrag greift diese Fragestellung auf, indem die Ergebnisse einer Literaturanalyse zum State-of-the-Art des Effekts den aktuellen Entwicklungen in der Medienproduktion gegenübergestellt werden. Die hier vorgestellten ersten Überlegungen zeigen, dass die Grundaussage auch weiterhin Gültigkeit besitzt, aber eine Reihe weiterer Aspekte wie beispielsweise Economies of Scope in das Konstrukt Einzug halten müssen, um die Kostenstruktur der aktuellen Medienproduktion realistisch abbilden zu können.

AbstractMulti-unit firms have productivity advantages over competitors because of their use of a non-rival asset—firm-specific knowledge—in several units. Using knowledge-intensive services leads to economies of scope in production by multi-unit firms. Such headquarter are usually supplied by parent companies and serve to link different firm units. Headquarter services are difficult to quantify in statistics or surveys, except when they cross-borders and the exchange of services between MNEs and their offshore subsidiaries becomes apparent. This study therefore focuses on IT service imports to explain productivity differences among foreign affiliates of multinational firms in Germany. The authors base the analysis on the population of foreign multinational firms active in Germany and analyze what effect the import of IT services has on their productivity. They find that IT headquarter service flows have significant impacts on foreign affiliates’ productivity in general and US affiliates in particular. As the average IT-service flows (per firm and partner) from parent countries are significantly higher for US affiliates than non-US affiliates, they conclude that the import of IT services from the parent-company is a source of the productivity advantages of US affiliates in Germany.

<p><strong>OBJECTIVE:</strong> The main purpose of this study is to estimate the technical efficiency of the United Arab Emirates (UAE) hospitals and examine the effect of hospital size on estimated technical efficiency scores.</p><p><strong>METHODS: </strong>Using 2012 data from Ministry of Health, Dubai Health Authority, and Health Authority in Abu Dhabi,<strong> </strong>we employed a nonparametric method, data envelopment analysis (DEA), to estimate the technical efficiency of 96 private and governmental hospitals in the UAE. Efficiency scores are calculated using both Banker, Charnes, and Cooper (BCC) and Charnes, Cooper, and Rhodes (CCR) models. </p><p><strong>RESULTS: </strong>The average technical efficiency of the UAE hospitals is estimated at 59% based on the BBC model and at 48% based on the CCR model. The optimal size of a hospital in the UAE is between 100 to 300 beds. We also found evidence of economies of scope between the provision of outpatient and inpatient care in the UAE hospitals.</p><p><strong>CONCLUSION: </strong>Our findings indicate that only one third of the UAE hospitals are technically efficient. There is evidence to suggest that there are considerable efficiency gains yet to be made by many UAE hospitals. Additional empirical research is needed to inform future health policies aimed at improving both the technical and allocative efficiency of hospital services in the UAE. </p>
