Suddenly recessions are defined by jobs reports and unemployment rate instead of GDP. Labor force participation rate, though... that's not a thing.
Three points:
One
On the flip side, if you look at GDP in 2000 and 2001, there never was two quarters of negative economic growth during that period.
This is from FRED Real GDP per quarter
https://fred.stlouisfed.org/series/GDPC11st quarter, 2000: 12,935.252
2nd quarter 2000: 13,170.749
3rd quarter 2000: 13,183.890
4th quarter 2000: 13,262.250
1st quarter 2001: 13,219.251
2nd quarter 2001: 13,301.394
3rd quarter 2001: 13,248.142
4th quarter 2001: 13,284.881
1st quarter 2002: 13,394.910
So, GDP declined in the first and third quarter of 2001 after slowing in the 3rd quarter of 2000. Based on this, and other factors, the NBER determined that there was a recession sometime during 2000 and 2001 even though there never was two consecutive quarters of negative economic growth.
Because of the NBER determination, everybody in the media refers to the recession of 2000 and 2001, and because of them, every person refers to the recession of 2000 and 2001. Yet, using this coloquial definition of 'two consecutive quarters of negative economic growth' there never was a recession.
The point being: That the NBER determines when a recession occurs is not 'sudden.' Also, if you use the coloquial definition of a recession, there was no recession from around 1991 to sometime in 2007, or 16 years of consecutive yearly real economic growth. I think that is good evidence, that barring a shock like Covid, that the Federal Reserve generally does its job well.
I hope some people have a better understanding from this little historical economic lesson.
