This paper provides new evidence on the objectives and determinants of different typesof innovations and patents, environmental as opposed to other innovations and patents,and different variants of environmental innovations and patents. We investigate howfirm-specific and sector-specific driving...

The development of climate-friendly technologies and its diffusion across countries is of key importance to slow climate change. This paper considers technologies in the mobile air-conditioning (MAC) sector which is a major contributor of fluorinatedgreenhouse gas emissions. Using patents as an...

Drawing upon the literature on environmental innovation and social metabolism, this paper investigates whether technology can lessen the problem of scarce natural resources. We focus on fossil and biomass materials as important resources for production and consumption. Utilizing a dynamic panel...

Does knowledge from dirty technologies spill over to clean technologies? This question has implications for the ease of switching from dirty to clean R&D. We measure knowledge spillovers using the proportion of citations in clean patents that directly refer to dirty technologies and the degrees...

Technology transfer is one of the most contentious issues in international negotiations on climate change. Despite its recognition at international platforms such as the United Nations Framework Convention on Climate Change, G20, etc., the independent review of Climate Technology Centre and...

We find that high environmental penalties are associated with a subsequent decline in green patents by U.S. manufacturing firms. Utilizing the 1990 Clean Air Act Amendment (1990 CAAA) as a quasi-natural experiment, we show that an exogenous shock increasing expected environmental penalties...

Open innovation is the subject of increased scholarly debate. A lot of attention has thereby been paid to firm-centered open innovation, characterized by a for-profit motive and the interplay between patents and contracts, resulting in restricted openness. Inspired by the increasing call for...

The traditional view of innovation, which implies that companies innovate on their own, has been recently challenged by the 'open' innovation concept promoting the use of external knowledge. Collaboration between firms has always existed in one way or another, however, large-scale open...

A change in US patent law in the early 1980’s increased the value of patents, particularly for firms in the electronics and semiconductors industry, yet many of the industry’s leading firms did not embrace patenting after the change. We show through an in-depth study of International...

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...
