We develop a model of growth driven by successive improvements in `General Purpose Technologies' (GPTs), such as the steam engine, electricity, or micro-electronics. Each new generation of GPTs prompts investments in complementary inputs and impacts the economy after enough such compatible...

History and theory alike suggest that General Purpose Technologies (GPT's), such as the steam engine or electricity, may play a key role in economic growth. In a previous paper (Helpman and Trajtenberg, 1994) we incorporated this notion into a Grossman-Helpman growth model, and explored the...
