Directed technological change and factor shares

Author

Listed:
  • Hart, Rob

Abstract

Directed technological change (DTC) concerns how stocks of factor-augmenting knowledge evolve relative to each other. We model investment in factor-augmenting knowledge at firm level, and show that relative investment rates depend on the relative factor shares and elasticities. Furthermore, we argue that links between the knowledge stocks and substitution between final goods are crucial to the long-run evolution of the economy.
