The article looks at why some countries suddenly reduced their trade deficits in the 1990s and early 2000s. They found that factors like saving money, increasing exports, having enough reserves, and managing debt played a big role. Even though the impact of exchange rates was unclear, these countries saw slower economic growth before the trade deficit reduction, followed by strong growth afterwards. In fact, after the trade deficit reduction, these countries' economies grew by about 1.20% more in the second year. The study also suggests that countries with long-lasting trade deficits might be spending too much on consumption.
