The NBER (as of Dec. 7) needs more time to declare the end of the recession. When they do decide, the trough will likely be April 2002.
The behavior of the economy this year indicates that the decline in activity that began last year may have come to an end. But recent data show that additional time is needed to be confident about the interpretation of the movements of the economy last year and this year. The NBER’s Business Cycle Dating Committee will determine the date of a trough in activity when it concludes that a hypothetical subsequent downturn would be a separate recession, not a continuation of the past one.
