We investigate the short- and long-term effects of a natural gas boom in an economy where energy can be produced with coal, natural gas, or clean sources and the direction of technology is endogenous. In the short run, a natural gas boom reduces carbon emissions by inducing substitution away...

This paper discusses the growth model with environmental constraints recently presented in (Acemoglu et al., 2011) which focuses on the redirection of technical change by climate policies with research subsidies and a carbon tax. First, Acemoglu et al.'s model and chosen parameters yield...

Fulfilling the commitments embedded in the Paris Agreement requires a climate-technology revolution. Patented innovation of low-carbon technologies is lower in the EU than in selected peers, and very heterogeneous across member states. We motivate this fact with an endogenous model of directed...

Can directed technical change be used to combat climate change? We construct new firm-level panel data on auto industry innovation distinguishing between dirty (internal combustion engine) and clean (e.g. electric and hybrid) patents across 80 countries over several decades. We show that firms...

This paper introduces endogenous and directed technical change in a growth model with environmental constraints. A unique final good is produced by combining inputs from two sectors. One of these sectors uses "dirty" machines and thus creates environmental degradation. Research can be directed...

In this paper we present the so-called Schumpeterian approach to economic growth, in which growth is primarily driven by entrepreneurial innovations that are themselves influenced by the institutional environment. We argue that this more micro-founded approach both, questions the old divisions...
