We propose a theory of trade in which comparative advantages reveal themselves gradually over the path of development. Following the Ricardian tradition, countries specialise and export the set of goods they are able to produce at relatively lower cost given their exogenous initial endowments....

We provide evidence showing that the degree of diversification of import sources of finely disaggregated commodities rises monotonically along the growth path. This result is robust to different measures of import diversification and the inclusion of a large set of additional control variables....

This paper studies the link between migration, remittances and productive assets accumulation for a panel of poor rural households in Mexico over the period 1997-2006. In a context of financial markets imperfections, migration may act as a substitute for imperfect credit and insurance provision...
