Great Depression

The Great Depression was a period of severe global economic downturn that occurred from 1929 to 1939. It was characterized by high rates of unemployment and poverty, drastic reductions in industrial production and trade, and widespread bank and business failures around the world.^[1] The economic contagion began in 1929 in the United States, the largest economy in the world, with the devastating Wall Street stock market crash of October 1929 often considered the beginning of the Depression.^[2]

The Depression was preceded by a period of industrial growth and social development known as the "Roaring Twenties". However, much of the profit generated by the boom was invested in speculation, such as on the stock market, rather than in more efficient machinery or wages. A consequence was a growing disparity between an affluent few and the majority. Banks were subject to limited regulation under laissez-faire economic policies, resulting in increasing debt. By 1929, declining spending had led to reductions in the output of consumer goods and rising unemployment. Despite these trends, stock investments continued to push share values upward until late in the year, when investors began to sell their holdings. After the Wall Street crash of late October, the slide continued for nearly three years, with the market losing some 90% of its value and resulting in a loss of confidence in the entire financial system. By 1933, the U.S. unemployment rate had risen to 25 percent, about one-third of farmers in the country had lost their land because they were unable to repay their loans, and about 11,000 of the country's 25,000 banks had gone out of business. Many city dwellers, unable to pay rent or mortgages on homes, were made homeless and relied on begging or on charities to feed themselves.

The U.S. federal government initially did little to help. President Herbert Hoover, like many of his fellow Republicans, believed in the need to balance the national budget and was unwilling to implement an expensive welfare program. In 1930, Hoover signed the Smoot–Hawley Tariff Act, which taxed imports with the intention of encouraging buyers to purchase American products, but this worsened the Depression, because foreign governments retaliated with tariffs on American exports. Hoover changed course, and in 1932 Congress established the Reconstruction Finance Corporation, which offered loans to businesses and local governments. The Emergency Relief and Construction Act of 1932 enabled expenditure on public works to create jobs. In the 1932 presidential election, Hoover was defeated by Franklin D. Roosevelt, who from 1933 pursued "New Deal" policies and programs to provide relief and create new jobs, including the Civilian Conservation Corps, Federal Emergency Relief Administration, Tennessee Valley Authority, and Works Progress Administration. Historians still disagree on the effects of the policies, with some claiming that they prolonged the Depression instead of shortening it.

Between 1929 and 1932, worldwide gross domestic product (GDP) fell by an estimated 15%. In the U.S., the Depression resulted in a 30% contraction in GDP.^[3] Recovery varied greatly around the world. Some economies, such as the U.S., Germany and Japan started to recover by the mid-1930s; others, like France, did not return to pre-shock growth rates until the eve of World War II, which began in 1939.^[4] Devastating effects were seen in both wealthy and poor countries: all experienced drops in personal income levels, prices, tax revenues, and profits. International trade fell by more than 50%, and unemployment in some countries rose as high as 33%.^[2] Cities around the world, especially those dependent on heavy industry, were heavily affected. Construction virtually halted in many countries, and farming communities and rural areas suffered as crop prices fell by up to 60%.^[5][6][7] Faced with plummeting demand and few job alternatives, areas dependent on primary sector industries suffered the most.^[8] The outbreak of World War II in 1939 ended the depression, as it stimulated factory production, providing jobs for women as militaries absorbed large numbers of young, unemployed men.

The precise causes for the Depression are disputed. One set of historians, for example, focusses on non-monetary economic causes. Among these, some regard the Wall Street crash as the main cause; others consider that the crash was a mere symptom of more general economic trends of the time which had already been underway in the late 1920s.^[2][9] A contrasting set of views, which rose to prominence in the later part of the 20th century,^[10] ascribes a more prominent role to monetary policy failures. According to those authors, while general economic trends can explain the emergence of the recession, they fail to account for its severity and longevity. These were caused by the lack of an adequate response to the crises of liquidity which followed the initial economic shock of October 1929 and the subsequent bank failures accompanied by a general collapse of the financial markets.^[3]
