Doomed to Deficits? Aggregate U.S. Trade Flows Re-Examined
This paper examines the stability of import and export demand functions for the United States over the 1975q1-2001q2 period. Using the Johansen maximum likelihood approach, an export demand function is readily identified. In contrast, there appears to be a structural break in the import demand function in 1995; specifications incorporating this break pass tests for cointegration, although the price elasticity is not statistically significant. Only when excluding computers and parts from the import series is a stable import demand function detected. The resulting point estimates do not exhibit the income asymmetry typically found in other studies of aggregate U.S. trade flows.
