In this paper we analyse the evolution of the current account as a percentage of GDP for a group of Central and Eastern European Countries. Instead of analysing only the variable for unit roots, we go a step further and test for different speeds of mean reversion dependent on break dates endogenously determined. We apply the Bai and Perron method to find that most countries have managed to balance their current account, but some of them should keep an eye on the low speed of mean reversion and the deviation of the time trend from balance.

中欧和东欧经常账户可持续性：结构变化和危机

在本文中，我们分析了一组中欧和东欧国家经常账户在GDP中所占百分比的演变。我们不仅仅分析单位根变量，而是更进一步，根据内生确定的中断日期测试均值回复的不同速度。我们应用Bai和Perron方法发现，大多数国家/地区已经设法平衡了经常账户，但其中一些国家应注意均值回归的低速以及时间趋势偏离平衡的趋势。
