DOES HYSTERESIS OCCUR IN TRADE? SOME EVIDENCE FOR BILATERAL EXPORT FLOWS AT A DISAGGREGATED LEVEL

This article shows that hysteresis effects can be specific to certain commodities and/or to trade with particular countries. We perform two tests to investigate two different implications of the hysteresis hypothesis. The first implication is that the relative price elasticity of demand for exports rises when a market becomes more competitive. The second implication is that relative export prices are insensitive to changes in the exporter's relative exchange rate. We find that hysteresis is not an insignificant phenomenon for some specific goods. Out of 14 products we can accept Baldwin's hysteresis hypothesis for three: manufacture of drugs and medicines, manufacture of office computing and accounting machinery, and manufacture of radio, television, and communication equipment. These are sectors with higher than average sunk costs in terms of advertising expenditure.
