Can directed technical change be used to combat climate change? We construct new firm-level panel data on auto industry innovation distinguishing between dirty (internal combustion engine) and clean (e.g. electric and hybrid) patents across 80 countries over several decades. We show that firms...

Research efforts towards new energy sources and towards the efficiency of energy use will be vital to reducing CO2 abatement costs in the long term. Can such efforts be induced by price instruments? Economists often cite induced technological change as a possible consequence of environmental...

Based on patent data and industry specific energy prices for 18 OECD countries over 30 years we investigate on an industry level the impact of energy prices on green innovation activities. Our econometric models show that energy prices and green innovation activities are positively related and...

This paper analyzes the evolution of technological development in Brazil, considering the impacts of the Brazilian Intellectual Property Law, introduced in 1996, in Brazilian enterprises` patenting. Firstly, the paper presents the main debates about intellectual property rights. Then, it...

We investigate incidence and evolution of patent thickets. Our empirical analysis is based on a theoretical model of patenting in complex and discrete technologies. The model captures how competition for patent portfolios and complementarity of patents affect patenting incentives. We show that...

This paper aims to establish how the innovative activity in Finland has changed over time in the transition from a resource-driven economy to a knowledge-driven economy. The paper first takes a historical perspective on innovation and industrial activity in Finland through a descriptive...

Hochentwickelte Industriestaaten bedürfen permanenter Innovation, um weiterhin wachsen zu können. Nur dadurch ist es möglich, auf dem Weltmarkt Preise zu erzielen, die günstige Terms of Trade und ein hohes Lohnniveau ermöglichen. Die Förderung von Innovation wird damit zu einer zentralen...

Based on a comprehensive data set comprising 13 countries, 22 industries and a period of 30 years we investigate the impact of internal and external knowledge pools of both green and other than green technologies on green patent activities. It turned out that the internal green knowledge stock...
