Capital deepening increases the relative output of the more capital-intensive sector but simultaneously induces a reallocation of capital and labor away from that sector. Using a two-sector...

This paper studies whether labor scarcity encourages technological advances, that is, technology adoption or innovation, for example, as claimed by Habakkuk in the context of nineteenth-century United States. I define technology as strongly labor saving if technological advances reduce the...
