U.S. Export Performance in Agricultural Markets

by Mark Gehlhar and Thomas Vollrath

This report develops a method, called trade-share accounting (TSA), that establishes the relationship between trade structure and market share. U.S. market shares are commonly used as measures of export performance in international markets and are frequently cited statistics in USDA publications. A drop in the U.S. market share is not necessarily associated with displaced U.S. sales from competing suppliers. Accurate interpretation of change in the agricultural market share requires understanding of the changing structure of world trade.
