If something like this under-reporting of reinvested earnings or other balance-of-payments credits has gone on in the past, it may still be going on today – especially with US firms becoming aggressive about arbitraging corporate income tax. And if true investment income is indeed as large as double what is reported, the true US current-account balance entered the black in 2009 and has been in surplus ever since.
如果类似于这一低报再投资利润或其他收支平衡盈余的行为过去存在，那么今天可能依然存在——特别是考虑到美国企业正热衷于公司所得税套利。而如果真正的投资所得实际上要比报告数字大一倍，那么真正的美国经常项目余额在2009年就不再是赤字，并在此后一直是盈余。
