How much should governments subsidize the development of new clean technologies? We use patent citation data to investigate the relative intensity of knowledge spillovers in clean and dirty technologies in two technological fields: energy production and transportation. We introduce a new...

Policies on climate change that encourage 'clean innovation' while displacing 'dirty innovation' could have a positive impact on short-term economic growth while avoiding the potentially disastrous reduction in GDP that could result from climate change over the longer term.

A major obstacle for the transformation to a low-carbon economy is the risk of a carbon lock-in: fossil fuel-based ('dirty') technologies dominate the market although their carbon-free ('clean') alternatives are dynamically more efficient. We study the interaction of learning-by-doing spillovers...

Within the field of environmental economics, the role of technological change has received much attention. The long-term nature of many environmental problems, such as climate change, makes understanding the evolution of technology an important part of projecting future impacts. Moreover, in...

Policies on climate change that encourage 'clean innovation' while displacing 'dirty innovation' could have a positive impact on short-term economic growth while avoiding the potentially disastrous reduction in GDP that could result from climate change over the longer term.

Eco-innovation plays a crucial role in reducing carbon emissions. Exploiting the consolidated IPAT / STIRPAT framework, this paper studies whether a relationship exists between green technological change and both CO2 emissions and emission efficiency (CO2/VA), exploiting a rich panel covering 95...

The starting point of this paper is that the exit of venture-backed firms often takes place through sales to large incumbent firms. We show that in such an environment, venture-backed firms have a stronger incentive to develop basic innovations into commercialized innovations than incumbent...
