Questions: The Great Depression: Causes, Collapse, and Recovery Policies

Question 1

By what percentage did US industrial production fall between 1929 and 1933?

• A. About 10% — a significant but manageable decline
• B. About 20% — comparable to a typical severe recession
• C. About 47% — a nearly unprecedented collapse in productive capacity
• D. About 80% — leaving the US economy at near-total standstill

Answer: (C)

US industrial production fell approximately 47% between 1929 and 1933 — a catastrophic collapse without modern precedent. US real GDP fell by about 30% over the same period. Unemployment rose from about 3% in 1929 to 25% in 1933 — one in four American workers was unemployed. In some cities and industrial regions, unemployment exceeded 50%. These numbers are difficult to contextualize: the 2008-09 financial crisis, considered the worst since the Depression, saw US GDP fall roughly 4.3% and unemployment peak around 10%. The Depression was roughly 7-10 times worse by these measures.

Question 2

The Smoot-Hawley Tariff Act (1930) helped the United States recover from the Depression by protecting American industry from foreign competition.

• T. True
• F. False

Answer: False

The Smoot-Hawley Tariff Act of 1930 raised US tariffs on over 20,000 imported goods to historically high levels, triggering retaliatory tariffs from US trading partners (Canada, Europe). International trade, already contracting due to the Depression, collapsed further — US exports fell by about two-thirds between 1929 and 1932. Rather than protecting American industry, Smoot-Hawley helped turn an American recession into a global depression by fragmenting international trade. It is widely considered one of the most consequential policy mistakes of the Depression era. Over 1,000 economists signed a petition urging Hoover not to sign the bill, to no avail.

Question 3

What was the 'paradox of thrift' that Keynes identified, and why does it challenge classical economic theory?

Model answer: The paradox of thrift holds that when all individuals simultaneously try to save more (a rational response to economic uncertainty), the aggregate result is a reduction in total demand, which causes income to fall, so that total savings may actually decline. If everyone saves more and spends less, businesses face falling demand, reduce production, lay off workers, who then earn less and spend less still — a deflationary spiral. This paradox challenges classical economics, which held that savings are inherently virtuous and will be automatically channeled into investment. Keynes argued that in a recession, increased saving reduces demand and worsens the contraction; what is rational for individuals is irrational for the economy as a whole. The solution is for the government to step in as a 'spender of last resort,' maintaining demand through deficit spending when private spending collapses. This is the core Keynesian argument for fiscal stimulus during recessions.

The paradox of thrift is one of several 'fallacies of composition' in economics — what is true for the individual is not necessarily true for the aggregate. Understanding this is crucial for macroeconomics. The Depression was the empirical case that forced economists to take this seriously.

Question 4

Which of the following New Deal programs is most directly connected to the principle of counter-cyclical fiscal policy?

• A. The Securities Exchange Act (1934), which regulated financial markets
• B. The Social Security Act (1935), which created old-age pensions
• C. The Works Progress Administration (1935), which employed millions in public works — directly injecting demand into the economy through government spending
• D. The Banking Act (1933, Glass-Steagall), which separated commercial from investment banking

Answer: (C)

The Works Progress Administration (WPA), created in 1935, employed approximately 8.5 million Americans over its lifespan in construction, arts, education, and other public works. It was the most direct implementation of Keynesian counter-cyclical fiscal policy: the government directly hiring unemployed workers when private employers would not, thereby injecting spending into the economy. The WPA built 40,000 miles of roads, 2,500 hospitals, 5,900 school buildings, and 1,000 airports. The Social Security Act (option B) had important longer-term economic stabilization effects (automatic stabilizers) but was not primarily designed as immediate stimulus. Securities regulation and banking reform were important but operated through different mechanisms.

Question 5

Why did Roosevelt's fiscal caution in 1937 — attempting to balance the budget after partial recovery — cause the 'Roosevelt Recession' of 1937-38?

Model answer: By 1937, US unemployment had fallen from 25% to about 14%, and Roosevelt, responding to political pressure about budget deficits, sharply cut federal spending and raised taxes. The Federal Reserve simultaneously tightened monetary policy. This combined fiscal and monetary contraction hit an economy that had recovered partly but was still dependent on government support. Unemployment shot back up from 14% to 19% within a year; industrial production fell sharply. The 1937-38 recession within a depression demonstrated the danger of premature fiscal consolidation: withdrawing government support before private demand had fully recovered caused a relapse. Keynes and others argued the lesson was clear — expansionary policy should be maintained until genuine private recovery, not withdrawn the moment some indicators improve. The episode influenced policymakers in 2009-10, as some economists warned against premature austerity following the financial crisis (though this advice was not universally followed).

The 1937 recession-within-the-Depression is sometimes called the 'mistake of 1937' and serves as a cautionary tale in macroeconomic policy. Its lessons were applied (imperfectly) in the 2008-09 response and debated intensely during the subsequent debates about fiscal austerity in the US and Europe 2010-2015.
