Intra-Industry Trade Expansion and Employment Reallocation between Sectors and Occupations

This paper re-examines the relationship between trade and labour market adjustment costs by explicitly considering the effects of occupational mobility. We investigate the hypothesis that intra-industry trade expansion entails lower adjustment costs than inter-industry trade expansion—the so-called Smooth Adjustment Hypothesis (SAH). This paper makes two new contributions. First, the introduction of a new adjustment variable that considers reallocation between sectors and occupations. Second, a test of the SAH using panel data with relevant trade and non-trade control variables, which overcomes some of the methodological limitations of former studies. The results suggest a confirmation of the SAH and stress the importance of considering the effects of worker moves between occupations in the study of trade-induced adjustment.
