Abstract

Technological innovations improve the welfare of a country facing fixed terms of trade, but may lead to immiserization when the terms of trade are adversely affected. This paper establishes that transport innovation can be immiserizing for a small country when the transport sector exhibits variable returns to scale. The release of resources from the transport sector triggers Rybczynski-like effects, and the resulting expansion (contraction) in the volume of trade and in the demand for transport services raises unit costs of these services, and may reduce welfare in the presence of decreasing (increasing) returns to scale.
