| Abstract: | Dramatic changes are occurring in the nature of international trade. Production processes increasingly involve a sequential, vertical trading chain stretching across many countries, with each country specializing in particular stages of a good's production sequence. The authors document a key aspect of these vertical linkages - the use of imported inputs in producing goods that are exported - which they call vertical specialization. Using input - output tables from 10 OECD and four emerging market countries, they calculate that vertical specialization accounts for 21 % of these countries' exports, and grew almost 30% 1970-1990. |
