Emerging markets with naturally higher interest rates are swamped with hot money inflows. Emerging market central banks intervene to prevent their currencies from rising precipitately. They lose monetary control and domestic prices begin inflating. Primary commodity prices rise worldwide unless interrupted by an international banking crisis＇. This cyclical inflation on the dollar＇s periphery only registers in the US core eonsumer price index with a long lag. The zero interest rate policy also fails to stimulate the US economy as domestic finaneial intermediation by banks and money market mutual funds is repressed. Because China is forced to keep its interest rates below market-clearing levels, it also suffers from finaneial repression, although in a form differing from that in the USA.展开更多

This study proposes a nonlinear (progressive) capital flow tax as a solution. We first demonstrate that the collateral requirement of international borrowing can give rise to multiple equilibria and self-fulfilling financial crises. We then show that the crisis equilibrium characterized by large exchange rate depreciation, capital flight and welfare loss can be eliminated by imposing a nonlinear (progressive) tax scheme on capital outflows with the marginal tax rate increasing with the size of individual capital outflows. The implementation of such a tax scheme in China is also discussed.展开更多
