答案:The final criticism of the IMF is that it has become too powerful for an institution that lacks any real mechanism for accountability. The IMF has determined macroeconomic policies in those countries, yet according to critics such as noted economist Jeffrey Sachs, the IMF, with a staff of less than 1,000, lacks the expertise required to do a good job. Evidence of this, according to Sachs, can be found in the fact that the IMF was singing the praises of the Thai and South Korean governments only months before both countries lurched into crisis. Then the IMF put together a draconian program for South Korea without having deep knowledge of the country. Sachs’s solution to this problem is to reform the IMF so it makes greater use of outside experts and its operations are open to greater outside scrutiny.
