Among economists and economic historians, consensus on the Great Depression is partial and unevenly distributed. Broad, cross-institutional agreement exists on several discrete mechanical questions-particularly the monetary contraction of 1929-33, the international transmission role of the gold standard, and the contractionary effect of the Smoot-Hawley Tariff. No comparable consensus exists on two larger questions: what triggered the initial 1929 downturn, and what caused the U.S. economy's slow recovery and high unemployment through the rest of the 1930s, including the net effect of New Deal policy. On these latter questions, expert opinion divides along theoretical lines (monetarist, Keynesian, and supply-side/institutional schools), and the divide has persisted across decades of subsequent research rather than converging.¹⁾

There is broad agreement among economic historians, dating to Milton Friedman and Anna Schwartz's 1963 *A Monetary History of the United States*, that a sharp contraction in the U.S. money supply-driven by Federal Reserve passivity during a wave of bank failures-turned a severe recession into a depression. This finding has been replicated and extended using independent datasets and methods by researchers operating from different theoretical starting points, including Peter Temin, Ben Bernanke, and Barry Eichengreen.²⁾ Bernanke has stated that the past several decades of research produced “a broad consensus about the causes of the Depression,” attributing much of that convergence to studies widening the analysis beyond the United States alone.³⁾ This is a consensus about a *mechanism*-how the contraction deepened and spread-rather than about its ultimate origin.

A distinct and well-corroborated consensus holds that the interwar gold standard transmitted monetary contraction across countries and constrained central banks' ability to respond to it. Barry Eichengreen's *Golden Fetters* (1992), building on earlier work by Ehsan Choudhri and Levis Kochin and by Eichengreen and Jeffrey Sachs, established that fixed exchange rates under gold forced countries to match contractionary policy abroad, and that countries which left gold earlier recovered sooner.⁴⁾ Bernanke and Harold James independently confirmed the cross-country pattern using a different international dataset.⁵⁾ This is now standard material in graduate macroeconomic-history training and is treated as settled within the field. Economists writing in the classical-liberal tradition, including Robert Higgs, generally accept the gold-standard transmission finding while disputing its relative weight against domestic policy causes; see Limits and Open Questions below.

There is consensus that the 1930 Smoot-Hawley Tariff Act, whatever its intent, worsened the Depression by inviting foreign retaliation and shrinking the volume of international trade, though the precise magnitude of its contribution is disputed and likely modest relative to monetary factors. A 1995 survey of the Economic History Association found roughly two-thirds of respondents agreeing the act at least worsened conditions.⁶⁾ Notably, this agreement spans economists working from Keynesian, monetarist, and Austrian frameworks-an unusually cross-paradigm result for the field.

While mechanisms that deepened the Depression after 1930 are comparatively well agreed upon, the trigger for the initial 1929 contraction remains contested. Candidate explanations-the stock market crash itself, prior Federal Reserve tightening in 1928-29, agricultural overproduction and falling farm income, and structural weaknesses in the banking system-are not mutually exclusive, and historians differ on their relative weighting. The St. Louis Federal Reserve's own public-education material states plainly that the 1929 crash alone was insufficient to cause a depression of this severity, implying additional causes were necessary but leaving their relative importance unresolved.⁷⁾

No consensus exists on what drove the U.S. recovery after 1933 or on the New Deal's net contribution to it. Three positions persist in the literature without convergence:

• Monetary-expansion view: Christina Romer's quantitative work attributes nearly all pre-1942 recovery to monetary expansion-chiefly gold inflows from Europe-and finds that fiscal stimulus and self-correcting market forces played a comparatively small role.⁸⁾
• Keynesian fiscal-stimulus view: This school credits New Deal deficit spending, particularly after 1937, with stabilizing output, and points to the 1937-38 “Roosevelt Recession”-when spending was cut and monetary policy tightened-as evidence that withdrawing stimulus stalled recovery.
• Policy-hindrance view: Economists including Richard Vedder, Lowell Gallaway, Gary Dean Best, and Robert Higgs argue that New Deal labor and regulatory policy, including the National Industrial Recovery Act's wage and price codes, prolonged high unemployment by raising labor costs and discouraging investment through what Higgs terms “regime uncertainty”-a climate in which business leaders could not predict whether existing property and contract rights would hold.⁹⁾

A 1995 survey of economic historians found this question-what to make of New Deal policy's net effect-was one of the propositions showing substantial disagreement among the forty surveyed, alongside the causes of the Depression's onset.¹⁰⁾ Wikipedia's own summary of the literature states there is no consensus among economists regarding the motive force behind the recovery that continued through most of the Roosevelt years.¹¹⁾

Separately, there is no consensus on whether U.S. wage-rigidity policy under Hoover-encouraged at 1929 White House conferences urging firms to maintain wage rates-measurably delayed wage adjustment broadly, or only at a small number of large firms that attended those conferences.
