What was not factors was not one of the causes of the recession in 1937?

One factor that was not a cause of the 1937 recession was a lack of technological innovation. Unlike previous economic downturns that were often linked to technological stagnation, the 1937 recession was primarily attributed to fiscal tightening, the Federal Reserve's decision to raise interest rates, and reduced government spending. Additionally, the economy was still recovering from the Great Depression, and these policy shifts led to a contraction in economic activity. Thus, technological advancements were not a contributing factor to this specific recession.
