Rich, poor and growth-miracle nationsmultiple equilibria revisited

Laburpena

This paper presents a two-sector growth model of international trade that can account for the key features of the postwar world development experience. Two sectors represent the traditional primitive production and the modern sophisticated production. Due to increasing returns in the modern sector, the open-economy version of our model gives rise to three different equilibria: one in which the country produces only primitive goods and converges to a low-income steady state; another in which it produces both primitive and sophisticated goods and converges to the world-average steady state; and a third in which it specializes in the production of sophisticated goods and converges to a balanced growth path. We argue that the development experiences of poor, rich and growth-miracle countries are well described by these three equilibria.
