Abstract
The business cycle accounting "wedge" methodology is used to identify the mechanisms driving the rapid growth of Hong Kong, Singapore, South Korea, and Taiwan since 1966. Analysis with a neoclassical growth model reveals that growth in these economies has been sustained by different mechanisms at different stages of development. Factor accumulation, which arises primarily from increases in capital wedges, accounts for most of the rapid growth in the earlier stages. However, in the later stages, total factor productivity growth becomes the primary driver.
