Are Imports and Exports Cointegrated? An International Comparison

In this paper, we use the Johansen and Juselius cointegration technique to examine the long-run convergence between imports and exports for a number of industrialized countries. The results indicate that there exists a long-run steady-state relationship between imports and exports for most countries in the sample. The policy implications of our findings are that the countries are not in violation of their international budget constraints and, more importantly, there is no productivity gap between the domestic economy and the rest of the world, implying a lack of permanent technological shocks to the domestic economy
