Recession is called by NBER. And NBER has never failed to put the recession stamp on back-to-back drops in GDP. So …
Yes, it has, though only for a period where it was doing business cycle dating purely long-retrospectively and with no contemporary political/policy weight (1947).
OTOH, that just reinforces the idea that the idea that two down quarters doesn't always mean recession isn't a novelty or invented for contemporary political/policy impact.
