Disaggregated trade data are used to examine changing trade patterns for five developed economic regions: the USA, the European Union, Australia, Canada and Japan. This study covers the 1980-1997 time period, during which international trade for most goods faced less border protection. Changing trade patterns are found for the USA, Japan, and the EU, while persistent trade patterns are observed for Australia and Canada. Classifying goods into four groups, trade patterns found in manufactured goods were the most dynamic, and trade in bulk agricultural goods the most persistent.
