How persistent is industry specialization over time in industrialized countries?

Edward N. Wolff

    Research output: Contribution to journalArticle


    I use the 1994 OECD Structural Analysis database, which provides statistics on output for 33 manufacturing industries in 14 OECD countries over the period 1970 to 1993. I find that in 1970, these countries tended to specialize manufacturing production in very different industries and that most countries retained their specialization between 1970 and 1993. I conclude that the general stability in industries of specialization over time lends support to the increasing internal returns to scale models and tends to contradict the standard factor-price equalization models. The results of this paper also suggest that increasing internal returns to scale and learning-by-doing may serve as a complement to patent protection and other forms of intellectual property rights.
