SummaryIn this paper, we investigate the informational content of citation-based research evaluations. To illustrate our analysis we refer to the 2005 Handelsblatt ranking of German academic economists. We make extensive use of the recently developed Hirsch-index and relate citation incidence to publication success, career age, and the topicality of the individual researchers’ field of specialization. We arrive at the conclusion that citation-based indicators provide a very incomplete picture of research performance. To obtain acceptable bibliometric research evaluations, citation based indicators need to be complemented with indicators that measure publication success more directly.

In this paper we theoretically derive an international Rybczynski matrix. Its elements indicate the aggregate output change in a country when endowment with one or more factors in the same or another country is increased. This allows us to characterize the production structure in 11 countries of the European Union. Starting from a baseline case with free trade in final goods only, we analyze two types of interaction between countries: international trade of intermediate inputs and internationally mobile capital.
