摘要：This paper analyzes trade among and the convergence of per capita
income for India, Pakistan, Bangladesh, and Sri Lanka. The extent of trade
and its relationship with the magnitude of income convergence is studied
among these countries and their trading partners. We use intra-trade
convergence and the difference-in-differences approach for the estimations.
The results demonstrate that an increase in trade between the groups
decreases the per capita income differential. Our results suggest that trade
liberalization policies could be effective in achieving convergence. More
importantly, we find that the per capita income of our source countries
converged more rapidly under post-liberalization regimes than pre-
liberalization regimes.
