Growth: Scale or Market-Size Effects?

Chu, Angus C. and Cozzi, Guido (2018): Growth: Scale or Market-Size Effects?

Abstract

Is the supply of researchers or the demand for technologies more important for innovation? The supply of research labor captures a scale effect, whereas the demand from production labor for technologies captures a market-size effect. We find that both the scale effect and the market-size effect are important for innovation and their relative importance depends on the relative intensity of lab-equipment R&D and knowledge-driven R&D in the innovation process.
