This chapter summarizes the basic characteristics of patent data as an innovation indicator and reviews some of the recent research using patent data, focusing on major developments since Griliches in 1990 [Griliches, Z. (1990). “Patent statistics as economic indicators: A survey”. Journal...

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...

We develop a theoretical framework to investigate the impact of patent policies and emis- sion taxes on green innovation that reduces the emission output ratio, and on the emission level. In the absence of green consumers, the introduction of patents results in a paradox whereby increasing...

We present a dynamic model where the accumulation of patents generates an increasing number of claims on sequential innovation. We study the equilibrium innovation activity under three regimes: patents, no-patents and patent pools. Patent pools increase the probability of innovation with respect...

While recent literature has focused on explaining the determinants of green innovations, it is not well understood how such innovations affect performance. To analyse the relationship between green innovation and performance, new industry-level panel data were exploited: these include 12 OECD...

This paper begins by surveying recent economic studies of the relationships between technology transfer, intellectual property, innovation and diffusion in emerging countries. It applies this literature to the Indian case. India is a potentially useful case study for several reasons. India has...

This chapter reviews the empirical literature on the determination of firms’ and industries’ innovative activity and performance, highlighting the questions addressed, the approaches adopted, impediments to progress in the field, and research opportunities. We review the...

Using a narrative identification of US tax changes over the post-WWII period, we show that corporate income tax cuts foster R&D spending and innovation, leading to a persistent increase in aggregate productivity and output. In contrast, changes in the average personal income tax rate have mostly...
