Question

what cause a u.s. recession in 1974

Answer 1

The 1973–75 recession or 1970s recession was a period of economic stagnation in much of the Western world during the 1970s, putting an end to the general post-World War II economic boom. It differed from many previous recessions as being a stagflation, where high unemployment coincided with high inflation. The period was also described as one of "malaise" (ill-ease; compare "depression").
