We introduce endogenous directed technical change into numerical integrated climate and development policy assessment. We distinguish expenditures on innovation (R&D) and imitation (international technology spillovers) and consider the role of capital investment in creating and implementing new...

R&D encompasses plenty of activities which are usually summarized under the terms of basic research, applied research and development. Although basic research is often associated with low appropriability it provides the fundamental basis for subsequent applied research and development....

Inventors often experience a low productivity after their company has been subject to a merger or acquisition (M&As). It is of central managerial interest to identify factors facilitating the integration of new inventive staff and thereby counteracting innovation declines after M&As. This paper...

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...

Based on a large data set containing information on occupations between 1979 and 1999, this study explores the ?black box? surrounding the skill?biased technological change hypothesis by analyzing the mechanisms that induce information technologies to be complementary to employees with higher...

This paper provides an overview of the treatment of technological change in economic models of environmental policy. Numerous economic modeling studies have confirmed the sensitivity of mid- and long-run climate change mitigation cost and benefit projections to assumptions about technology...

Non-technological innovation is an important element of firms? innovation activities that both supplement and complement technological innovation, i.e. the introduction of new products and new processes. We analyse the spread of nontechnological innovation in firms, their relation to...

Mit der Venture Capital (VC)-Finanzierung als Teil eines regionalen Innovationssystems sind Erwartungen verbunden, die Kommerzialisierung neuer Forschungsergebnisse in marktfähige Produkte in einer Region zu fördern. In Erwartung positiver Effekte eines solchen Kapitalzuflusses in eine Region...

The paper tests empirically the role of knowledge stocks to explain the regional distribution of Germany?s biotechnology founders. We present an unique approach to highlight the role of knowledge spillovers as we differentiate according the local embeddedness and research affinity of founders....

The present analysis investigates skill requirements in the workplace, measured directly by the task-composition of occupations. It shows that the task composition of occupations has shifted toward analytical and interactive activities and away from manual and cognitive routine activities in...
