Of course, temporary disturbances, a worsening of global payments imbalances, or macroeconomic policy mistakes, including those made in advanced economies and affecting the entire world economy, could undermine global growth. But the underlying “convergence differential,” owing to catch-up growth, is likely to continue to reduce the income gap between the old advanced economies and emerging-market countries.
当然，暂时性的动荡、全球收支失衡恶化以及宏观经济政策失误（包括哪些源自发达经济体但影响到全世界经济的失误）可能会破坏全球增长。但赶超增长所带来的基本的“趋同差”可能将继续减少老牌发达经济体和新兴市场国家间的收入差距。
