Trade intensity and business cycle synchronization : the case of East Asia

This paper examines whether increasing trade intensity among East Asian countries has led to a synchronization of business cycles. It extends the work of Shin and Wang (2004) in two ways: by (i) improving the specification of their business cycle correlation equation, and (ii) extending the sample to cover the period after the Asian financial crisis. The study finds that intra-industry trade, rather than inter-industry trade, is the major factor explaining business cycle co-movements in East Asia, with important implications for the prospects for a single currency in the region.
