This paper investigates the relationship between exports, imports and economic growth for South Korea and Japan by constructing a vector autoregression (VAR) model. Causality is examined between real GDP, real exports and real imports. Several principal results emerge from the empirical work. Firstly, the three variables are cointegrated for both countries, implying that a long-run steady state exists. Secondly, there is evidence of bi-directional causality between imports and economic growth for both countries. Finally, Japan seems to experience export-led growth, while GDP growth in South Korea has a negative effect on export growth. These contrasting findings could result from export goods in Japan exhibiting greater non-price competitive aspects, although their success fails to trigger a virtuous circle since growth fails to lead to increased exports, whilst for South Korea, output growth leads to a decrease in export growth suggesting a strong domestic market.
