This paper characterizes the interactions among studying abroad, return migration, and capital accumulation, in a two-country overlapping generations model with households of heterogeneous ability. The model exhibits positive selection of migration status (i.e., permanent, return, and...

We formulate a two-country, two-good, two-factor, two-period-lived overlapping generations model to examine how population aging determines the pattern of and gains from trade. Two main results are obtained. First, the aging country endogenously becomes a small country exporting the...

Aid for trade is a new foreign aid initiative to assist recipient countries to build trade-related infrastructure. We formulate a small-country, two-good (i.e., investment and consumption goods), two-factor (i.e., capital and labor) endogenous growth model with learning by doing and...

We formulate a two-country, continuum-good Ricardian model of trade and endogenous growth with endogenous trade status. After establishing the existence, uniqueness, and global stability of a balanced growth path, we show that, compared with the old balanced growth path, a permanent fall in the...

A two-final-good, one-primary-factor, small open endogenous growth model is constructed based on R&D. The model yields two steady states with different growth rates as potential equilibria. Depending on history and the external environment, the economy may fall into the poverty trap in free...
