Under the Kyoto Protocol, Clean Development Mechanism (CDM) is expected to facilitate the North-South knowledge spillovers for climate-friendly technologies. This paper examines the effects of this voluntary international climate cooperation on firm innovation and knowledge spillovers through...

This study examines the impact of barriers to knowledge diffusion in energy technologies in 29 countries from 1990 to 2015, distinguishing between efficient fossil-based generation and mature renewable options, namely wind and solar. We show that knowledge flows are higher in countries with...

We study an international climate agreement that assigns emission quotas to each participating country. Unlike the simplest models in the literature, we assume that abatement costs are affected by R&D activities undertaken in all firms in all countries, i.e. abatement technologies are...

With global climate change posing a major threat to human society, many countries have elevated "carbon neutrality" to a national strategy and put forward a vision of a zero-carbon future. In this process, environmental regulation (ER) and renewable energy technology innovation (RET) are...
