the National Bureau of Economic Research (NBER), which officially declares recessions, says the two consecutive quarters of decline in real GDP are not how it is defined anymore. The NBER defines a recession as a significant decline in economic activity spread across the economy, lasting more than a few months, normally visible in real GDP, real income, employment, industrial production, and wholesale-retail sales.
要等NBER 怎么说，如果就业，收入，生产和销售不滑落，就没有recession。
