The division of labor and economic development

Building on three widely accepted premises (productivity gains from the division of labor, efficiency gains derived from the proximity of suppliers and users of certain inputs, the division of labor is limited by the extent of the market) this paper shows that a small, open economy may be caught in an underdevelopment trap in which a shallow division of labor (i.e., a low variety of specialized inputs) is self-reinforcing. In turn, the shallow division of labor leads to a relatively low rate of return to capital, so foreign investment or domestic capital accumulation may not materialize.
