Das Max-Planck-Institut zur Erforschung von Wirtschaftssystemen Jena führte im Sommer 2002 in Kooperation mit dem Lehrstuhl für Mikroökonomik der Friedrich-Schiller-Universität Jena eine Befragung der in Jena ansässigen Unternehmen durch. Die wichtigsten bereits erkennbaren Ergebnisse...

Die aktuelle bildungspolitische Diskussion hat mit dem Vorschlag, Eliteuniversitäten zu schaffen, einen vorläufigen Höhepunkt erreicht. Von vielen Seiten wird hierzu Stellung bezogen. Der vorliegende Beitrag dient zum Einen zur Versachlichung der Diskussion und zum Anderen dazu, in knapp...

For given product specifications by two competing firms the demand levels are determined by a randomly generated ideal composition of aspects. Firms can vary some or all aspects of these products, based on information about own (and other's) previous demand. Although the product space is much...

In this paper different formulae for the decomposition of aggregate productivity levels and changes are applied to a sample of German manufacturing firms that pertain to 11 different industries at a roughly two-digit level observed over the period 1981-1998. Productivity is measured by a...

This paper investigates how the survival of firms over the industry life cycle is affected by different kinds of knowledge, namely post-entry experience, pre-entry experience, and knowledge acquired by innovative activity. Therefore, a statistical survival analysis is performed for the German...

This paper provides empirical tests of hypotheses of cooperative behavior provided by evolutionary approaches in the resource-based view of the firm. The influences of "technological proximity", individual incentives to cooperate and managerial tools to the choice of research partner are...

Knowledge is one of the most important determinants in single-industry studies of firm survival over the life cycle. Different kinds of knowledge, namely post-entry experience, pre-entry experience, and knowledge acquired by innovative activity positively influence the survival chances of firms....

In an experimental setting, firms in a duopoly market engage in a patent tournament and compete for profit-enhancing product advancements. The firms generate income by matching exogenously defined demand preferences with an appropriately composed product portfolio of their own. Demand...

We investigate cooperative behavior within technology regions in patenting activities. Case studies of local innovation systems point out certain characteristics fruitful to innovation and regional growth but often pronounce historical singularities as major influence. We provide evidence on the...
