Growth, R&D, and uncertainty

Author

  • Tsuboi, Mizuki

Abstract

I develop and analytically solve the stochastic Romer model in which the creation of ideas is driven by a stochastic process. I show that higher uncertainty about R&D, through the reallocation effects of resources among sectors, slows down economic growth and deteriorates welfare. The results suggest that persistently high uncertainty tends to severely restrict the scope of sustained income growth.
