An impact of economic integration through trade: on business cycles for 10 East Asian countries

Many recent studies about East Asian countries discussed “natural” economic integration through trade, but there are few rigorous empirical studies on how their economies were affected by the evolution of economic integration within the region. This paper investigates the effect of bilateral trade dependence on the co-movement of business cycles for 10 East Asian countries. We find that economic fluctuations tend to be more synchronized within the region as trade interdependence among them deepens. This finding suggests the necessity of cooperative efforts to prevent or adjust unfavorable future economic crisis in East Asia.
