Der Beitrag behandelt den Einfluss des Gründungsgeschehens auf die regionale Entwicklung. Viele dieser Wirkungen sind indirekter Natur und müssen sich nicht notwendig in der Region niederschlagen, in der die Gründung stattfand. Empirische Analysen für westdeutsche Regionen zeigen, dass nur...

We introduce a new two-dimensional measure for the heterogeneity of performance within groups of economic units.

The traditional approach to measuring allocative efficiency is based on input prices, which are rarely known at the firm level. This paper proposes a new approach to measure allocative efficiency which is based on the output-oriented distance to the frontier in a profit - technical efficiency...

A new approach in German innovation policy organizes contests of proposals for developing innovation networks. Based on an overview of the different programs, we investigate the advantages, problems and limitations of such an approach. We find that this type of policy may have a relatively large...
