This paper examines the empirical dynamics of countries' technological specialization in six technology fields using distribution dynamics, a methodology involving non-parametric estimation of probability distributions and Markov stochastic kernels for each field. Innovation in all the fields is...

In the United States, as in most industrialized nations, aggregate technological advancement declined during the 1970s and early 1980s. The U.S. Congress was quick to respond to this down turn by passing a number of technology- and innovation-related initiatives, one of which was the National...

This paper investigates the impact of alternative environmental policy instruments on technological innovations aiming to improve energy efficiency in buildings. The empirical analysis focuses on three main types of policy instruments, namely regulatory energy standards in buildings codes,...

We employ a distribution dynamics approach to examine the empirical dynamics of technological specialisation in industrial countries. Using patent data, distributions of a specialisation index and Markov stochastic kernels are estimated non-parametrically for each country. Three are the main...

A frequently made claim in the innovation literature is that important inventions involve the transfer of new knowledge from one technological domain to another. This study uses U.S. patents granted from 1976-2006 to identify the role of knowledge acquired from outside each patent’s...

We study the impact of environmental regulations on the patent activities for wind turbines between 1980 and 2008. We explicitly control for energy market liberalisation and take a potential interaction between liberalisation and policy instruments into account. We find a strong and highly...

This article considers innovation, intellectual assets and intellectual property rights (IPRs) since 1990, with particular regard to the high-income countries. It begins with a discussion of the changing nature of innovation and the increasing importance of intellectual assets, then continues...

The amount of greenhouse gas emissions and consequent climate changes and social responses will depend substantially upon the rapid development and widespread dissemination of a wide variety of new mitigation and adaptation technologies. The international approach adopted by the UN Framework...
