A dynamic random effects probit model is estimated on the first six waves of the German Socio-Economic Panel to test for state dependence effects in male unemployment behaviour. Estimation of the model is based on the marginal likelihood approach. In the model an individual's unemployment...

We test the assimilation hypothesis as initially proposed by Chiswick (1978) by making. use of a rich panel dataset for Germany which allows us to control for unobserved population heterogeneity and potential selectivity bias arising from an individual's re-migration decision and employment...

Der Beitrag untersucht die Effektivität der Innovationsförderung in den neuen Ländern. Dabei wird ein doppelter Vergleich angestellt. Zum einen analysieren wir die Auswirkungen der Förderung hinsichtlich der FuE-Anreize und der FuE-Ergebnisse durch einen Vergleich von geförderten und...

The Importance and Contribution of new technology-based Firms (NTBFs) to long term economic development is at the center of a controversial debate. This paper provides an overview of the current status of research on various issues concerning NTBFs in Germany. The issues covered include the...

The missing effect of investments of firms in information and communication technologies on productivity is studied by various recent papers (e.g. Oliner and Sichels 1994, Landauer 1995, Brynjolfsson and Hitt 1996). Several explanations are given for this missing link. Our paper deals with two...

This paper develops a three stage oligopoly game for R&D cooperation, R&D expenditure and product market competition. In the first stage, firms decide whether or not to conduct R&D in cooperation with other firms. In the second stage the level of R&D investment is determined. Finally, firms...

Established theories in international business come to different conclusions when specifically applied to the analysis of the international activities of start-up companies in high-technology industries. Using a new dataset of 495 British and German start-ups operating in high-technology...
