"Market Integration and Economic Policy Uncertainty in International Soybean Trade"
Authors: Robertson, Dewey


Abstract
Recent rises in global tensions and deteriorating multilateral relationships threaten
market integration and established trade flows. This study assesses market integration among large soybean market participants (Argentina, Brazil, China, United States) and seeks to capture the extent to which economic policy uncertainty affects integrated price relationships. Using a vector error correction model, we examine the relationship between weekly cash export and import prices among trading partners. Consistent with previous studies, we find that export and import prices have a long-run equilibrium relationship and price shocks are transmitted across regions. We further find that global economic policy uncertainty raises export and import prices in all regions. Domestic economic policy uncertainty influence follows price leadership; as price leader, U.S. domestic economic policy uncertainty spills over into global markets, putting downward pressure on prices. On average, import prices are affected more by economic policy
uncertainty than export prices.
