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.

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.

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...

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...

We study the political determination of a hypothetical land tax, which internalises a negative environmental externality from biofuels. The tax allocates land from biofuels towards forestry. Lobbying affects the tax rate, so that the sector with the lower elasticity of land demand determines the...

This paper considers the impact of differences in endogenous technological change between two countries on global pollution emissions under international strategic interaction in environmental policies. First, we demonstrate that an environmentally lagging country's technology may continue to...

We argue that expectations about future energy use affect the transition from fossil fuels to renewable substitutes, because of an interaction between innovation and resource scarcity. The paper presents a model of directed technical change to study this interaction. We find that resource-saving...

This paper introduces the evolving understanding and conceptualization of innovation process models. From the discussion of different approaches towards the innovation process understanding and modeling two types of approaches to the evolution of innovation models are developed and discussed....
