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...

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...

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...

Can a country grow faster by saving more? We address this question both theoretically and empirically. In our model, growth results from innovations that allow local sectors to catch up with the frontier technology. In relatively poor countries, catching up with the frontier requires the...
