  • 演講摘要 : If international trade is strictly trade in intermediate goods, would the common presumption, that small, less developed economies (the South) lose from trade wars still be true? We address this question by constructing a dynamic general equilibrium model in which the North and South trade technology-embodied intermediate goods. The presence of extensive margin effects yields a novel channel of scale-scope trade-off: The South counters the losses from a trade war in the volume and value of trade (scale) with an upward movement along the value chain (scope), thereby mitigating the detrimental effects of the trade war. Using calibration we find that for our benchmark model the reduction in the volumes and values of trade caused by a trade war is mitigated, and the scale-scope trade-off induces a moderately higher average productivity and aggregate technology used by the South.
