This paper aims to shed light on the role of technological opportunities for green innovation by studying the case of Green ICT innovation. We test two hypotheses: (1) Firms active in low-opportunity technological areas are less innovative; (2) Firms active in low-opportunity technological areas...

Die vorliegenden Überlegungen sind darauf gerichtet, die Ideen und wesentlichen Gedanken Nationaler Innovationssysteme aufzugreifen und in den Kontext einer wissensbasierten Ökonomie zu stellen. Neben den Akteuren oder Spielern geht es um die Regeln und Funktionsmechanismen und schließlich...

This paper provides a labour supply explanation to the observation that in Germany employment changes are asymmetric during the business cycle. Employment increases are slower, because the reservation wage of workers increases in times of job uncertainty. Workers are afraid in those periods of...

The US labour market is characterized by a high skill wage mark-up and low unemployment, while the German labour market has a low skill wage mark-up and a high, mainly unskilled unemployment rate. This paper adds an innovative labour supply explanation to the discussion how these distinct labour...

This study investigates productivity effects to firms introducing new environmental technologies. The literature on within-firm organisational change and productivity suggests that firms can get higher productivity effects from adopting new technologies if complementary organisational changes...

Many countries, especially in Europe, have ambitious goals to transform their national energy systems towards renewable energies. Technological change in both renewable production and efficient use of energy can help to make these targets come true. Using a panel of German firms linked to the...

Dieser Beitrag nimmt aus theoretischer und ökonometrischer Sicht zu der Kontroverse über die Bedeutung der qualifikatorischen Lohnstruktur zur Erklärung der Beschäftigungsstruktur Stellung. Basierend auf einer Einteilung in drei Qualifikationsgruppen zeigt sich empirisch, dass die Entlohnung...

We compare two options of integrating discrete working time choice of heterogenous households into a general equilibrium model. The first, known from the literature, produces household heterogeneity through a working time preference parameter. We contrast this with a model that directly...

Die heutige intensive Auseinandersetzung mit dem Fragenkomplex "technischer Fortschritt" hat verschiedene historische Wurzeln und entstammt verschiedenen Forschungsrichtungen. Technischer Fortschritt wird heute von den meisten Ökonomen als ökonomisches Phänomen anerkannt, dem volle...

China recently surpassed the USA as the greatest global source of patent applications. However, without internationally comparable measures of patent quality it remains questionable whether China's patent expansion constitutes the rise of a new technological superpower. Our novel quality index...
