Capital Accumulation and Dynamic Gains from Trade
We compute welfare gains from trade in a dynamic, multicountry model with capital accumulation. We examine transition paths for 93 countries following a permanent, uniform, unanticipated trade liberalization. Both the relative price of investment and the investment rate respond to changes in trade frictions. Relative to a static model, the dynamic welfare gains in a model with balanced trade are three times as large. The gains including transition are 60 percent of those computed by comparing only steady states. Trade imbalances have negligible effects on the cross-country distribution of ...
