In this paper the time series properties of the outcomes of two different specifications of a nonparametric productivity analysis are compared using data for three- and four- digit U.S. manufacturing industries over the period 1958-96. The first model is standard and does not account for...

The approach of quantile regression is used to explore the fine details of the relation of current period and lagged productivity levels. Productivity is calculated as total factor productivity by a nonparametric approach using data for U.S. manufacturing industries on the three- and four-digit...

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...

In this paper the profitability of German car manufacturing firms is related to different indicators for the knowledge incorporated in the firms since the birth of the industry in 1886. The analysis is performed with an ordered probit model, where information about the kind of exit of the firms...

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....

Universities and public research organizations are said to be an integrative and essential element of a functioning innovation system as they play a vital role not only in the generation of new technological knowledge, but also in its diffusion. We analyse four East German local networks of...

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...
