This paper reviews the performance of the East German economy in the turbulent quarter-century following reunification and draws some conclusions for the reunification of North and South Korea. In this period, the gap in output per capita between East and West Germany declined at a speed not far from empirical estimates of the neoclassical growth model, yet systematic total factor productivity differentials persist despite identical institutional frameworks and significant investment in the eastern regions. At the same time, regional disparities in income, well-being, and health are little different from those found within West Germany, and net migration has ceased. On this human metric, German uniÖcation has been an unqualiÖed success. For Korea, an effort of this dimension will be costly. A back-of-the- envelope calculation suggests that Korean unification will cost roughly twice as much as its German counterpart.
