A footloose capital model of economic development

We present a footloose capital model in a two‐country economy and the manufacturing and natural resource sectors with heterogeneous manufacturing firms to analyze the impacts of trade liberalization and technological progress on the net capital flows, net export, and social welfare. Our main analytical result is that a lagged country initially experiences capital outflow due to the high technological gap in the manufacturing sector with increasing returns to scale, then capital inflow due to the home market effect. This corresponds with the fact that China was a net importer of manufactured goods initially, and became a net exporter recently. These results are consistent with the data obtained after the reform and opening‐up policy in 1978.
