There has been a concomitant rise in R&D and the rate of economic growth in emerging countries. Analyzing a panel of 31 emerging countries, we find convincing evidence of scale effects which make government policies potent for long-run growth. This contrasts sharply with the well known findings...

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...

Defensive innovations in developed countries can explain the empirical phenomenon that openness towards trade with less-developed countries does not necessarily induce a substantial increase in the wage differential and trade volumes. Building on step-by-step innovations as introduced by Aghion...
