A disaggregated analysis of EU imports: the implications for the study of patterns of trade and technology
研究了1988-2002年欧盟制成品进口单价趋势，通过高度分解数据发现单价趋势因出口经济体类型和产品类型而异，对经济分析和政策制定有重要启示。
This paper examines trends in the unit prices of manufactured imports into the European Union (EU) in the period 1988–2002. This is undertaken at a high level of disaggregation, and it is this decomposition which we believe has important implications both for a range of bodies of economic analysis and for policy. The analyses undertaken in this paper confirm that disaggregation matters in helping to identify unit-price trends. We have also shown that unit-price trends vary with the type of economy exporting into Europe and the type of product being exported, and that these results are robust at high levels of disaggregation.
