查询词典 knowledge base system

This paper includes several parts: first, some important concepts of the thesis have been defined, a theoretical overview of currency crisis has been finished; then, we have described the history of the international monetary system; later, three chapes have been arranged to discuss the mechanism of currency crisis under fixed and floating and intermediate exchange rate system respectively. The part of the fixed exchange rate system mainly includes the analysis of the collapse of the international gold standard system, the Bretton Woods system and the the European Monetary System; in the part of the floating exchange rate system, the volatility problem under freely floating exchange rate system has been studied; the part of the intermediate exchange rate system mainly includes the analysis of currency crises in regional dollar standard system and the currency board system. And finally, we have analysed the inevitability of the appearance of new type regional monetary cooperation patterns, and how these cooperations avoid currency crises.
