Sense and Nonsense on Asia's Export Dependency and the Decoupling Thesis

Abstract

It has often been argued that East Asia needs to switch from an export-led growth model to a domestic-demand led growth model so as to reduce its vulnerability to a sharp slowdown in the US economy. This paper argues that, indeed, in the foreseeable future, East Asia's business cycle is unlikely to decouple with that of the US, but the switch-of-growth-model argument is problematic because it mixes up the effects of external trade on an economy's cyclical developments and its long-term growth potential. The paper argues that the desirable way to reduce external vulnerabilities is to diversify export markets and to further strengthen domestic institutions and policies in order to reduce the impact of temporary shocks, not by reducing the degree of openness or the share of exports in GDP. The paper further agues that the rising size of domestic demand in Mainland China will overtime help the rest of the region to diversify its export markets away from the major industrialized countries.
