Economic growth, TFP convergence and the world export of ideas: A century of evidence

Abstract

This paper examines the effect of international patent stock on total factor productivity for 16 OECD countries over the past 120 years. The results show that the international patent stock is highly influential for economic growth and, together with knowledge spillovers through the channel of imports, has contributed significantly to TFP growth and σ-convergence among the OECD countries over the past 120 years. © 2008 The editors of the Scandinavian Journal of Economics.
