First, the very short-run exchange rate fluctuations were investigated, theoretically and empirically, with market microstructure approach. The academic conventional wisdom is that the exchange rate is unpredictable and follows a random walk process. However, private financial institutions spent millions of dollars in an effort to predict the exchange rate. The obvious puzzle is solved as new information to the market has to be digested within several hours, during the period financial institutions with better interpretation of new information can predict the direction of the movements. The research shows that such activities are feasible, and also volatility persists for some time.Second, the currency crisis contagion to another country without obvious macroeconomic weakness is analyzed for possible linkage of the countries. It was shown that trade linkage is important in the strength of contagion from one country to another.Third, foreign exchange interventions were believed to be ineffective if interventions were sterilized. However, the research shows that interventions are effective under a certain set of conditions, even when they are sterilized. Moreover, it was shown that the monetary authorities tend to intervene when the rate is away from the long-run equilibrium and moving away from the longrun equilibrium quickly.

首先，运用市场微观结构方法对极短期汇率波动进行了理论和实证研究。学术界的传统观点是，汇率是不可预测的，并且遵循随机游走过程。然而，私人金融机构花费了数百万美元来预测汇率。这个明显的难题得到了解决，因为市场的新信息必须在几个小时内消化，在此期间，对新信息有更好解读的金融机构可以预测走势方向。研究表明，此类活动是可行的，而且波动性会持续一段时间。其次，分析了货币危机向宏观经济不明显疲软的国家蔓延的可能性。结果表明，贸易联系对于从一国向另一国蔓延的强度至​​关重要。第三，如果干预措施被冲销，外汇干预措施被认为是无效的。然而，研究表明，干预措施在某些条件下是有效的，即使是在被消毒的情况下。此外，研究表明，当利率偏离长期均衡并迅速偏离长期均衡时，货币当局倾向于进行干预。
