External adjustment and the global crisis
分析了全球金融危机前后发达国家与新兴市场的外部失衡调整过程，发现逆差国主要通过压缩国内需求而非汇率变动来实现调整，对理解危机后国际资本流动和汇率政策有参考价值。
The period preceding the global financial crisis was characterized by a substantial widening of current account imbalances across the world. Since the onset of the crisis, these imbalances have contracted to a significant extent. In this paper, we analyze the ongoing process of external adjustment in advanced economies and emerging markets. We find that countries whose pre-crisis current account balances were in excess of what could be explained by standard economic fundamentals have experienced the largest contractions in their external balance. We subsequently examine the contributions of real exchange rates, domestic demand and domestic output to the adjustment process (allowing for differences across exchange rate regimes) and find that external adjustment in deficit countries was achieved primarily through demand compression, rather than expenditure switching. Finally, we show that changes in other investment flows were the main channel of financial account adjustment, with official external assistance and ECB liquidity cushioning the exit of private capital flows for some countries.
