The Continental A40 engine is a carbureted four-cylinder, horizontally opposed, air-cooled aircraft engine that was developed especially for use in light aircraft by Continental Motors . It was produced between 1931 and 1941.
102-533: The 37 hp (28 kW) A40 was introduced in the depths of the Great Depression . At the time there were a number of small engines available but all suffered from either high cost, complexity, or low reliability. The A-40 addressed all those shortcomings and was instrumental in the production of light aircraft in the difficult economic constraints of the period. The A-40-4 introduced an increase in power to 40 hp (30 kW). The engine later inspired
204-634: A deflationary spiral started in 1931. Farmers faced a worse outlook; declining crop prices and a Great Plains drought crippled their economic outlook. At its peak, the Great Depression saw nearly 10% of all Great Plains farms change hands despite federal assistance. At first, the decline in the U.S. economy was the factor that triggered economic downturns in most other countries due to a decline in trade, capital movement, and global business confidence. Then, internal weaknesses or strengths in each country made conditions worse or better. For example,

The connection between leaving the gold standard as a strong predictor of that country's severity of its depression and the length of time of its recovery has been shown to be consistent for dozens of countries, including developing countries . This partly explains why the experience and length of the depression differed between regions and states around
408-509: A base year. The result would be that the GDP in 2000 equals $ 300 million × 1 ⁄ 2 = $ 150 million , in 1990 monetary terms. We would see that the country's GDP had realistically increased 50 percent over that period, not 200 percent, as it might appear from the raw GDP data. The GDP adjusted for changes in money value in this way is called the real GDP . The factor used to convert GDP from current to constant values in this way
510-518: A country becomes increasingly in debt, and spends large amounts of income servicing this debt this will be reflected in a decreased GNI but not a decreased GDP. Similarly, if a country sells off its resources to entities outside their country this will also be reflected over time in decreased GNI, but not decreased GDP. This would make the use of GDP more attractive for politicians in countries with increasing national debt and decreasing assets. Gross national income (GNI) equals GDP plus income receipts from
612-521: A country's borders, but by an enterprise owned by somebody outside the country, counts as part of its GDP but not its GNI; on the other hand, production by an enterprise located outside the country, but owned by one of its citizens, counts as part of its GNI but not its GDP. For example, the GNI of the US is the value of output produced by American-owned firms, regardless of where the firms are located. Similarly, if

The role that measurements of GDP played in World War II was crucial to the subsequent political acceptance of GDP values as indicators of national development and progress. A crucial role was played here by the U.S. Department of Commerce under Milton Gilbert where ideas from Kuznets were embedded into institutions . The history of

The economic growth can be expressed as real GDP growth rate or real GDP per capita growth rate . GDP can be adjusted for population growth, also called Per-capita GDP or GDP per person . This measures the average production of a person in

Among the 608 American banks that closed in November and December 1930, the Bank of United States accounted for a third of the total $ 550 million deposits lost and, with its closure, bank failures reached a critical mass. In an initial response to
1020-467: A greater reduction in credit. On 5 April 1933, President Roosevelt signed Executive Order 6102 making the private ownership of gold certificates , coins and bullion illegal, reducing the pressure on Federal Reserve gold. British economist John Maynard Keynes argued in The General Theory of Employment, Interest and Money that lower aggregate expenditures in the economy contributed to

Cheap foods were used, such as soups, beans and noodles. They purchased the cheapest cuts of meat—sometimes even horse meat—and recycled the Sunday roast into sandwiches and soups. They sewed and patched clothing, traded with their neighbors for outgrown items, and made do with colder homes. New furniture and appliances were postponed until better days. Many women also worked outside

Under the gold standard's price–specie flow mechanism , countries that lost gold but nevertheless wanted to maintain the gold standard had to permit their money supply to decrease and
1428-567: A serious issue in the 1930s. Support for increasing welfare programs during the depression included a focus on women in the family. The Conseil Supérieur de la Natalité campaigned for provisions enacted in the Code de la Famille (1939) that increased state assistance to families with children and required employers to protect the jobs of fathers, even if they were immigrants. In rural and small-town areas, women expanded their operation of vegetable gardens to include as much food production as possible. In

Britain went off the gold standard , and suffered relatively less than other major countries in the Great Depression. In the 1931 British election, the Labour Party was virtually destroyed, leaving MacDonald as prime minister for a largely Conservative coalition. In most countries of

Germany received emergency funding from private banks in New York as well as the Bank of International Settlements and the Bank of England. The funding only slowed the process. Industrial failures began in Germany, a major bank closed in July and a two-day holiday for all German banks was declared. Business failures were more frequent in July, and spread to Romania and Hungary. The crisis continued to get worse in Germany, bringing political upheaval that finally led to

Predictably, as a developed country, Japan has a higher GNI (by 182,779.46, in millions of USD), which is indicative that the production level in the country is higher than that of national production. On the other hand, the case with Armenia is the opposite, with GDP being lower than GNI by US$ 196.12 (in million). This demonstrates that countries receive investments and foreign aid from abroad. The Total income divided by
1836-658: Is a consensus that the Federal Reserve System should have cut short the process of monetary deflation and banking collapse, by expanding the money supply and acting as lender of last resort . If they had done this, the economic downturn would have been far less severe and much shorter. Modern mainstream economists see the reasons in Insufficient spending, the money supply reduction, and debt on margin led to falling prices and further bankruptcies ( Irving Fisher 's debt deflation). The monetarist explanation
1938-425: Is also sometimes expressed as: The third way to estimate GDP is to calculate the sum of the final uses of goods and services (all uses except intermediate consumption) measured in purchasers' prices. Market goods that are produced are purchased by someone. In the case where a good is produced and unsold, the standard accounting convention is that the producer has bought the good from themselves. Therefore, measuring
2040-838: Is calculated this way it is sometimes called gross domestic income (GDI), or GDP (I). GDI should provide the same amount as the expenditure method described later. By definition, GDI is equal to GDP. In practice, however, measurement errors will make the two figures slightly off when reported by national statistical agencies. This method measures GDP by adding incomes that firms pay households for factors of production they hire – wages for labour, interest for capital, rent for land and profits for entrepreneurship. The US "National Income and Product Accounts" divide incomes into five categories: These five income components sum to net domestic income at factor cost. Two adjustments must be made to get GDP: Total income can be subdivided according to various schemes, leading to various formulae for GDP measured by
2142-474: Is called the GDP deflator . Unlike consumer price index , which measures inflation or deflation in the price of household consumer goods, the GDP deflator measures changes in the prices of all domestically produced goods and services in an economy including investment goods and government services, as well as household consumption goods. Real GDP can be used to calculate the GDP growth rate, which indicates how much

#17327881227452244-473: Is contributed at each stage of production. This approach mirrors the OECD (Organisation for Economic Co-operation and Development) definition given above. Gross value added = gross value of output – value of intermediate consumption. Value of output = value of the total sales of goods and services plus the value of changes in the inventory. The sum of the gross value added in the various economic activities
2346-404: Is known as "GDP at factor cost". GDP at factor cost plus indirect taxes less subsidies on products = "GDP at producer price". For measuring the output of domestic product, economic activities (i.e. industries) are classified into various sectors. After classifying economic activities, the output of each sector is calculated by any of the following two methods: The value of output of all sectors
2448-551: Is often used as a metric for international comparisons as well as a broad measure of economic progress . It is often considered to be the world's most powerful statistical indicator of national development and progress. However, critics of the growth imperative often argue that GDP measures were never intended to measure progress, and leave out key other externalities , such as resource extraction , environmental impact and unpaid domestic work . Alternative economic indicators such as doughnut economics use other measures, such as
2550-480: Is often used to measure the economic health of a country or region. Several national and international economic organizations maintain definitions of GDP, such as the OECD and the International Monetary Fund . The ratio of GDP to the total population of the region is the GDP per capita and can approximate a concept of a standard of living . Nominal GDP does not reflect differences in
2652-493: Is supported by the contrast in how the crisis progressed in, e.g., Britain, Argentina and Brazil, all of which devalued their currencies early and returned to normal patterns of growth relatively rapidly and countries which stuck to the gold standard , such as France or Belgium. Frantic attempts by individual countries to shore up their economies through protectionist policies – such as the 1930 U.S. Smoot–Hawley Tariff Act and retaliatory tariffs in other countries – exacerbated
2754-587: Is that GDP defines its scope according to location, while GNI defines its scope according to ownership. In a global context, world GDP and world GNI are, therefore, equivalent terms. GDP is a product produced within a country's borders; GNI is product produced by enterprises owned by a country's citizens. The two would be the same if all of the productive enterprises in a country were owned by its own citizens and those citizens did not own productive enterprises in any other countries. In practice, however, foreign ownership makes GDP and GNI non-identical. Production within
2856-453: Is then added to get the gross value of output at factor cost. Subtracting each sector's intermediate consumption from gross output value gives the GVA (=GDP) at factor cost. Adding indirect tax minus subsidies to GVA (GDP) at factor cost gives the "GVA (GDP) at producer prices". The second way of estimating GDP is to use "the sum of primary incomes distributed by resident producer units". If GDP

With deficits mounting, the bankers demanded a balanced budget; the divided cabinet of Prime Minister Ramsay MacDonald's Labour government agreed; it proposed to raise taxes, cut spending, and most controversially, to cut unemployment benefits 20%. The attack on welfare was unacceptable to the Labour movement. MacDonald wanted to resign, but King George V insisted he remain and form an all-party coalition " National Government ". The Conservative and Liberals parties signed on, along with

Most historians and economists blame the Act for worsening the depression by seriously reducing international trade and causing retaliatory tariffs in other countries. While foreign trade

4284-481: The New Deal prolonged the Great Depression, as they argue that National Industrial Recovery Act of 1933 and National Labor Relations Act of 1935 restricted competition and established price fixing. John Maynard Keynes did not think that the New Deal under Roosevelt single-handedly ended the Great Depression: "It is, it seems, politically impossible for a capitalistic democracy to organize expenditure on
4386-544: The U.K. economy, which experienced an economic downturn throughout most of the late 1920s, was less severely impacted by the shock of the depression than the U.S. By contrast, the German economy saw a similar decline in industrial output as that observed in the U.S. Some economic historians attribute the differences in the rates of recovery and relative severity of the economic decline to whether particular countries had been able to effectively devaluate their currencies or not. This

Government-financed capital spending accounted for only 5% of the annual U.S. investment in industrial capital in 1940; by 1943, the government accounted for 67% of U.S. capital investment. The massive war spending doubled economic growth rates, either masking the effects of the Depression or essentially ending

Rural women made feed sack dresses and other items for themselves and their families and homes from feed sacks. In American cities, African American women quiltmakers enlarged their activities, promoted collaboration, and trained neophytes. Quilts were created for practical use from various inexpensive materials and increased social interaction for women and promoted camaraderie and personal fulfillment. Oral history provides evidence for how housewives in

According to later analysis, the earliness with which a country left the gold standard reliably predicted its economic recovery. For example, The UK and Scandinavia, which left the gold standard in 1931, recovered much earlier than France and Belgium, which remained on gold much longer. Countries such as China, which had

By 1933, the U.S. unemployment rate had risen to 25 percent, about one-third of farmers had lost their land, and about half of the country's 25,000 banks had gone out of business. Many people, unable to pay mortgages or rent, became homeless and relied on begging or 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

With significantly less money to go around, businesses could not get new loans and could not even get their old loans renewed, forcing many to stop investing. This interpretation blames the Federal Reserve for inaction, especially the New York branch . One reason why
5100-573: The beginning of the Depression. The Depression was preceded by a period of industrial growth and social development known as the " Roaring Twenties ". Much of the profit generated by the boom was invested in speculation , such as on the stock market , which resulted in growing wealth inequality . Banks were subject to minimal regulation under laissez-faire economic policies, resulting in loose lending and widespread debt. By 1929, declining spending had led to reductions in manufacturing output and rising unemployment . Share values continued to rise until
5202-465: The behavior of housewives. The common view among economic historians is that the Great Depression ended with the advent of World War II . Many economists believe that government spending on the war caused or at least accelerated recovery from the Great Depression, though some consider that it did not play a very large role in the recovery, though it did help in reducing unemployment. The rearmament policies leading up to World War II helped stimulate

While the precise causes for the occurrence of the Great depression are disputed and can be traced to both global and national phenomena, its immediate origins are most conveniently examined in the context of the U.S. economy, from which
5406-540: The concept of GDP should be distinguished from the history of changes in many ways of estimating it. The value added by firms is relatively easy to calculate from their accounts, but the value added by the public sector , by financial industries, and by intangible asset creation is more complex. These activities are increasingly important in developed economies, and the international conventions governing their estimation and their inclusion or exclusion in GDP regularly change in an attempt to keep up with industrial advances. In

The major advantage of GDP per capita as an indicator of the standard of living is that it is measured frequently, widely, and consistently. It is measured frequently in that most countries provide information on GDP every quarter, allowing trends to be seen quickly. It is measured widely in that some measure of GDP
5610-475: The crash was a mere symptom of more general economic trends of the time, which had already been underway in the late 1920s. A contrasting set of views, which rose to prominence in the later part of the 20th century, ascribes a more prominent role to failures of monetary policy . According to those authors, while general economic trends can explain the emergence of the downturn, they fail to account for its severity and longevity; they argue that these were caused by
5712-625: The crisis, the U.S. Congress passed the Smoot–Hawley Tariff Act on 17 June 1930. The Act was ostensibly aimed at protecting the American economy from foreign competition by imposing high tariffs on foreign imports. The consensus view among economists and economic historians (including Keynesians , Monetarists and Austrian economists ) is that the passage of the Smoot–Hawley Tariff had, in fact, achieved an opposite effect to what
5814-633: The decade. The Depression had devastating economic effects on both wealthy and poor countries: all experienced drops in personal income , prices ( deflation ), tax revenues, and profits. International trade fell by more than 50%, and unemployment in some countries rose as high as 33%. 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%. Faced with plummeting demand and few job alternatives, areas dependent on primary sector industries suffered

Some countries raised tariffs drastically and enforced severe restrictions on foreign exchange transactions, while other countries reduced "trade and exchange restrictions only marginally": The gold standard was the primary transmission mechanism of the Great Depression. Even countries that did not face bank failures and

There is also consensus that protectionist policies, and primarily the passage of the Smoot–Hawley Tariff Act , helped to exacerbate, or even cause the Great Depression.

The consensus among demand-driven theories is that a large-scale loss of confidence led to a sudden reduction in consumption and investment spending. Once panic and deflation set in, many people believed they could avoid further losses by keeping clear of the markets. Holding money became profitable as prices dropped lower and a given amount of money bought ever more goods, exacerbating

The Nazi women's organizations, other propaganda agencies and the authorities all attempted to shape such consumption as economic self-sufficiency was needed to prepare for and to sustain the coming war.

Extended families used mutual aid—extra food, spare rooms, repair-work, cash loans—to help cousins and in-laws. In Japan, official government policy was deflationary and the opposite of Keynesian spending. Consequently, the government launched a campaign across the country to induce households to reduce their consumption, focusing attention on spending by housewives. In Germany,
6936-553: The income approach. A common one is: The sum of COE , GOS and GMI is called total factor income; it is the income of all of the factors of production in society. It measures the value of GDP at factor (basic) prices. The difference between basic prices and final prices (those used in the expenditure calculation) is the total taxes and subsidies that the government has levied or paid on that production. So adding taxes less subsidies on production and imports converts GDP(I) at factor cost to GDP(I) at final prices. Total factor income

By May 1930, automobile sales declined to below the levels of 1928. Prices, in general, began to decline, although wages held steady in 1930. Then

Friedman and Schwartz argued that the downward turn in the economy, starting with the stock market crash, would merely have been an ordinary recession if the Federal Reserve had taken aggressive action. This view
7650-502: The most to make recovery possible. Every major currency left the gold standard during the Great Depression. The UK was the first to do so. Facing speculative attacks on the pound and depleting gold reserves , in September 1931 the Bank of England ceased exchanging pound notes for gold and the pound was floated on foreign exchange markets. Japan and the Scandinavian countries followed in 1931. Other countries, such as Italy and
7752-427: The most. 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 Great Depression are disputed. One set of historians, for example, focuses on non-monetary economic causes. Among these, some regard the Wall Street crash itself as the main cause; others consider that
7854-582: The need to balance the national budget and was unwilling to implement expensive welfare spending . In 1930, Hoover signed the Smoot–Hawley Tariff Act , which taxed imports with the intention of encouraging buyers to purchase American products, which worsened the Depression because foreign governments retaliated with tariffs on American exports. In 1932, Hoover established the Reconstruction Finance Corporation , which offered loans to businesses and support to local governments. In
7956-483: The physical volume of exports fall, but also the prices fell by about 1 ⁄ 3 as written. Hardest hit were farm commodities such as wheat, cotton, tobacco, and lumber. Governments around the world took various steps into spending less money on foreign goods such as: "imposing tariffs, import quotas, and exchange controls". These restrictions triggered much tension among countries that had large amounts of bilateral trade, causing major export-import reductions during
8058-431: The policies 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. 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 later in
8160-459: The political situation in Europe. In their book, A Monetary History of the United States , Milton Friedman and Anna J. Schwartz also attributed the recovery to monetary factors, and contended that it was much slowed by poor management of money by the Federal Reserve System . Chairman of the Federal Reserve (2006–2014) Ben Bernanke agreed that monetary factors played important roles both in
8262-463: The population is the Per capita income . The international standard for measuring GDP is contained in the book System of National Accounts (2008), which was prepared by representatives of the International Monetary Fund , European Union , Organisation for Economic Co-operation and Development , United Nations and World Bank . The publication is normally referred to as SNA2008 to distinguish it from
8364-430: The previous edition published in 1993 (SNA93) or 1968 (called SNA68) SNA2008 provides a set of rules and procedures for the measurement of national accounts. The standards are designed to be flexible, to allow for differences in local statistical needs and conditions. Within each country GDP is normally measured by a national government statistical agency, as private sector organizations normally do not have access to
8466-512: The products must be bought by somebody, therefore the value of the total product must be equal to people's total expenditures in buying things. The income approach works on the principle that the incomes of the productive factors ("producers", colloquially) must be equal to the value of their product, and determines GDP by finding the sum of all producers' incomes. Also known as the Value Added Approach, it calculates how much value
8568-445: The ratio between the value of money in the year the GDP was measured and the value of money in a base year. For example, suppose a country's GDP in 1990 was $ 100 million and its GDP in 2000 was $ 300 million . Suppose also that inflation had halved the value of its currency over that period. To meaningfully compare its GDP in 2000 to its GDP in 1990, we could multiply the GDP in 2000 by one-half, to make it relative to 1990 as
8670-587: The rest of the world minus income payments to the rest of the world. In 1991, the United States switched from using GNP to using GDP as its primary measure of production. The relationship between United States GDP and GNP is shown in table 1.7.5 of the National Income and Product Accounts . Another example that amplifies the difference between GDP and GNI is the comparison of developed and developing country indicators. The GDP of Japan for 2020
8772-408: The same result. They are the production (or output or value added) approach, the income approach, and the speculated expenditure approach. It is representative of the total output and income within an economy. The most direct of the three is the production approach, which sums up the outputs of every class of enterprise to arrive at the total. The expenditure approach works on the principle that all of
8874-434: The scale necessary to make the grand experiments which would prove my case—except in war conditions." According to Christina Romer , the money supply growth caused by huge international gold inflows was a crucial source of the recovery of the United States economy, and that the economy showed little sign of self-correction. The gold inflows were partly due to devaluation of the U.S. dollar and partly due to deterioration of
8976-401: The source data for the expenditures components are considered more reliable than those for the income components [see income method, above]." Encyclopedia Britannica records an alternate way of measuring exports minus imports: notating it as the single variable NX. GDP can be contrasted with gross national product (GNP) or, as it is now known, gross national income (GNI). The difference
9078-536: The total expenditure used to buy things is a way of measuring production. This is known as the expenditure method of calculating GDP. GDP (Y) is the sum of consumption (C) , investment (I) , government expenditures (G) and net exports (X − M) . Here is a description of each GDP component: C , I , and G are expenditures on final goods and services; expenditures on intermediate goods and services do not count. (Intermediate goods and services are those used by businesses to produce other goods and services within
9180-473: The words of one academic economist, "The actual number for GDP is, therefore, the product of a vast patchwork of statistics and a complicated set of processes carried out on the raw data to fit them to the conceptual framework." China officially adopted GDP in 1993 as its indicator of economic performance. Previously, China had relied on a Marxist-inspired national accounting system. GDP can be determined in three ways, all of which should, theoretically, give
9282-476: The world, recovery from the Great Depression began in 1933. In the U.S., recovery began in early 1933, but the U.S. did not return to 1929 GNP for over a decade and still had an unemployment rate of about 15% in 1940, albeit down from the high of 25% in 1933. There is no consensus among economists regarding the motive force for the U.S. economic expansion that continued through most of the Roosevelt years (and
9384-673: The world. The financial crisis escalated out of control in mid-1931, starting with the collapse of the Credit Anstalt in Vienna in May. This put heavy pressure on Germany, which was already in political turmoil. With the rise in violence of National Socialist ('Nazi') and Communist movements, as well as investor nervousness at harsh government financial policies, investors withdrew their short-term money from Germany as confidence spiraled downward. The Reichsbank lost 150 million marks in
9486-778: The worldwide economic decline and eventual recovery. Bernanke also saw a strong role for institutional factors, particularly the rebuilding and restructuring of the financial system, and pointed out that the Depression should be examined in an international perspective. Women's primary role was as housewives; without a steady flow of family income, their work became much harder in dealing with food and clothing and medical care. Birthrates fell everywhere, as children were postponed until families could financially support them. The average birthrate for 14 major countries fell 12% from 19.3 births per thousand population in 1930, to 17.0 in 1935. In Canada, half of Roman Catholic women defied Church teachings and used contraception to postpone births. Among
9588-658: Was a scramble to deflate prices to get the gold standard's conversation rates back on track to pre-WWI levels, by causing deflation and high unemployment through monetary policy. In 1933 FDR signed Executive Order 6102 and in 1934 signed the Gold Reserve Act . The two classic competing economic theories of the Great Depression are the Keynesian (demand-driven) and the Monetarist explanation. There are also various heterodox theories that downplay or reject
9690-443: Was a severe global economic downturn from 1929 to 1939. The period was characterized by high rates of unemployment and poverty; drastic reductions in liquidity , industrial production, and trade; and widespread bank and business failures around the world. 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
9792-478: Was a small part of overall economic activity in the U.S. and was concentrated in a few businesses like farming, it was a much larger factor in many other countries. The average ad valorem (value based) rate of duties on dutiable imports for 1921–1925 was 25.9% but under the new tariff it jumped to 50% during 1931–1935. In dollar terms, American exports declined over the next four years from about $ 5.2 billion in 1929 to $ 1.7 billion in 1933; so, not only did
9894-474: Was endorsed in 2002 by Federal Reserve Governor Ben Bernanke in a speech honoring Friedman and Schwartz with this statement: Let me end my talk by abusing slightly my status as an official representative of the Federal Reserve. I would like to say to Milton and Anna: Regarding the Great Depression, you're right. We did it. We're very sorry. But thanks to you, we won't do it again. The Federal Reserve allowed some large public bank failures – particularly that of
9996-493: Was first developed by Simon Kuznets for a 1934 U.S. Congress report, where he warned against its use as a measure of welfare (see below under limitations and criticisms ). After the Bretton Woods Conference in 1944, GDP became the main tool for measuring a country's economy. At that time gross national product (GNP) was the preferred estimate, which differed from GDP in that it measured production by
10098-426: Was given by American economists Milton Friedman and Anna J. Schwartz . They argued that the Great Depression was caused by the banking crisis that caused one-third of all banks to vanish, a reduction of bank shareholder wealth and more importantly monetary contraction of 35%, which they called "The Great Contraction ". This caused a price drop of 33% ( deflation ). By not lowering interest rates, by not increasing
10200-500: Was in the form of Federal Reserve demand notes. A "promise of gold" is not as good as "gold in the hand", particularly when they only had enough gold to cover 40% of the Federal Reserve Notes outstanding. During the bank panics, a portion of those demand notes was redeemed for Federal Reserve gold. Since the Federal Reserve had hit its limit on allowable credit, any reduction in gold in its vaults had to be accompanied by
10302-446: Was intended. It exacerbated the Great Depression by preventing economic recovery after domestic production recovered, hampering the volume of trade; still there is disagreement as to the precise extent of the Act's influence. In the popular view, the Smoot–Hawley Tariff was one of the leading causes of the depression. In a 1995 survey of American economic historians, two-thirds agreed that the Smoot–Hawley Tariff Act at least worsened
10404-470: Was the rollback of those same reflationary policies that led to the interruption of a recession beginning in late 1937. One contributing policy that reversed reflation was the Banking Act of 1935 , which effectively raised reserve requirements, causing a monetary contraction that helped to thwart the recovery. GDP returned to its upward trend in 1938. A revisionist view among some economists holds that
