Who is keynes in economics

Spending from one consumer becomes income for a business that then spends on equipment, worker wages, energy, materials, purchased services, taxes and investor returns. That worker's income can then be spent and the cycle continues. Keynes and his followers believed individuals should save less and spend more, raising their marginal propensity to consume to effect full employment and economic growth.

In this theory, one dollar spent in fiscal stimulus eventually creates more than one dollar in growth. This appeared to be a coup for government economists, who could provide justification for politically popular spending projects on a national scale.

This theory was the dominant paradigm in academic economics for decades. Eventually, other economists, such as Milton Friedman and Murray Rothbard , showed that the Keynesian model misrepresented the relationship between savings, investment, and economic growth. Many economists still rely on multiplier-generated models, although most acknowledge that fiscal stimulus is far less effective than the original multiplier model suggests.

The fiscal multiplier commonly associated with the Keynesian theory is one of two broad multipliers in economics. The other multiplier is known as the money multiplier.

This multiplier refers to the money-creation process that results from a system of fractional reserve banking. The money multiplier is less controversial than its Keynesian fiscal counterpart. Keynesian economics focuses on demand-side solutions to recessionary periods. The intervention of government in economic processes is an important part of the Keynesian arsenal for battling unemployment, underemployment, and low economic demand. The emphasis on direct government intervention in the economy often places Keynesian theorists at odds with those who argue for limited government involvement in the markets.

Keynesian theorists argue that economies do not stabilize themselves very quickly and require active intervention that boosts short-term demand in the economy.

Wages and employment, they argue, are slower to respond to the needs of the market and require governmental intervention to stay on track. Furthermore they argue, prices also do not react quickly, and only gradually change when monetary policy interventions are made, giving rise to a branch of Keynesian economics known as Monetarism.

If prices are slow to change, this makes it possible to use money supply as a tool and change interest rates to encourage borrowing and lending. Lowering interest rates is one way governments can meaningfully intervene in economic systems, thereby encouraging consumption and investment spending.

Short-term demand increases initiated by interest rate cuts reinvigorate the economic system and restore employment and demand for services. The new economic activity then feeds continued growth and employment. Without intervention, Keynesian theorists believe, this cycle is disrupted and market growth becomes more unstable and prone to excessive fluctuation.

Keeping interest rates low is an attempt to stimulate the economic cycle by encouraging businesses and individuals to borrow more money. They then spend the money they borrow. This new spending stimulates the economy. Lowering interest rates, however, does not always lead directly to economic improvement. Monetarist economists focus on managing the money supply and lower interest rates as a solution to economic woes, but they generally try to avoid the zero-bound problem.

As interest rates approach zero, stimulating the economy by lowering interest rates becomes less effective because it reduces the incentive to invest rather than simply hold money in cash or close substitutes like short term Treasuries. Interest rate manipulation may no longer be enough to generate new economic activity if it cannot spur investment, and the attempt at generating economic recovery may stall completely.

This is a type of liquidity trap. When lowering interest rates fails to deliver results, Keynesian economists argue that other strategies must be employed, primarily fiscal policy. Other interventionist policies include direct control of the labor supply, changing tax rates to increase or decrease the money supply indirectly, changing monetary policy, or placing controls on the supply of goods and services until employment and demand are restored.

Put very simply, the dynamic is otherwise that the recession forces private-sector companies and households to cut spending since their own revenues and incomes keep dwindling. If everyone reduces spending at the same time, however, incomes keep falling. The lack of demand for goods and services stalls economic activity. Governments can stop the downward spiral with deficit spending, as Keynes pointed out. Today, free-market radicals consider Keynes a leftist, because he insisted that governments have an important role to play in economic life.

The truth, however, is that he did not want to overcome capitalism. His theory actually helped to rescue it. Keynes proved to be very influential. For decades, western governments assumed a strong role in economic life, and that helped them prevail in the competition with the Soviet bloc. Keynes emphasised international cooperation. One reason was that exports can compensate demand shortfalls in one country if other countries buy its goods.

It thus made sense for national governments to coordinate their economic policies with one another. Multilateral institutions — in particular the World Bank and the International Monetary Fund IMF , which were established in see main story — were supposed to serve that purpose.

For several reasons, however, market orthodoxy was gaining strength again by the mids. One was that it proved much more difficult to bring about development in former colonies with Keynesian concept than to facilitate fast reconstruction in post-war Europe. Many developing countries became over-indebted. Another reason was that conservative economists began to blame inflation and unemployment on excessive government action. Multilateral institutions followed suit.

However, Keynesianism never died completely. Starting with Reagan, even conservative US leaders have had a pattern of relying on deficit spending to stimulate the economy when they needed to.

They did, however, resent the kind of public services Keynes recommended. Nonetheless, the World Bank and the IMF have been gradually returning to Keynesian ideas and backing off from market orthodoxy. To boost development, domestic spending on poverty alleviation was considered more important than repaying excessive debts owed to bilateral and multilateral agencies. After the Great Recession that started in with the collapse of the investment bank Lehman Brothers, the IMF accelerated its paradigm shift.

Keynesian ideas indeed fit the needs of our time. According to the IMF, there actually is no alternative in the current global setting. During the s, industrial production in the U. Unemployment reached 25 percent of the labor force. The Depression quickly spread to Europe and around the world. Relying on monetary solutions, most central banks cut interest rates and increased their money supply.

Britain finally abandoned the gold standard in But the economic damage was too severe. Consumers and businesses, gripped by fear of the future, hoarded cash and stopped spending.

Meanwhile, the U. As the worldwide depression became more severe, Keynes concluded that the free-market capitalist system had no remedy for a long and deep economic decline. Reducing interest rates and other monetary policy solutions were not enough. Keynes feared that if capitalism did not find a way to address mass unemployment, desperate people might turn to communism or fascism. Keynes argued that the government must save capitalism. In a radio broadcast, he revived his earlier backing of public-works projects and called for the major redevelopment of central London.

He asserted that the reduction of government relief payments to idle workers and an increase in tax revenue from suppliers of materials would offset the cost of such projects. In , Keynes began to argue publicly that the solution to mass unemployment depended on more, not less, government spending. This would require the government to borrow money and temporarily run a deficit.

Keynes pointed out that newly employed public project workers and suppliers would have cash to spend again, causing more demand for goods and services from private businesses. With more orders coming in, Keynes predicted, businesses would regain confidence and begin to hire workers. These workers would in turn spend their paychecks, multiplying demand, and so on. The Treasury continued to insist on spending cuts and balanced budgets. Keynes advised Roosevelt to focus first on the terrible unemployment problem.

Keynes presented his case for the government to borrow and spend large amounts of money on public-works projects. Nevertheless, Keynes had many meetings with government officials, Wall Street investors, business leaders, and university economists.

He tried his best to persuade them to embrace his big idea that explained why severe depressions occurred and how to end them. Keynes had been working on the puzzle of persisting unemployment in Britain for over a decade. In his book, Keynes declared that free-market capitalism had failed to provide a remedy for an economy stuck in a long-lasting depression with mass unemployment.

He wrote that relying on traditional monetary solutions like lowering interest rates was not enough. In uncertain times, businesses and individuals shy away from borrowing and lending money. When effective demand is up, businesses are profitable and employment is high. When uncertain consumers and investors sharply cut back on their spending, effective demand drops. Businesses lose confidence about future sales and income.

To cut costs, they start to lower prices, reduce wages, and lay off workers. Unemployed workers do not have much money to spend, which further reduces spending throughout the economy. Thus, a vicious downward spiral goes into motion, leading to failed businesses and mass unemployment. Keynes challenged a key free-market principle that saving is always good because it provides the money for investing in businesses. Keynes agreed saving was a good idea during normal economic conditions.

But he argued that it hurt the economy in a depression. If people hoard their cash in a depression, he said, they will obviously spend less. Keynes recognized that it makes sense for individuals to hold on to their money in uncertain times, but he pointed out that their reduced spending harms the economy as a whole.

As people spend less, companies sell less and invest less in production. The economy gets worse. Keynes answered that government should take on this role. Keynes pioneered the use of national economic statistics macroeconomics. Keynes called for governments in a depression to hire jobless workers directly for public works like roads, dams, and schools.

He said that the government would have to borrow the money by selling treasury bonds. It should not attempt to balance its budget but should run a temporary deficit.

Keynes concluded that lowering interest rates, expanding the money supply, and other monetary policies could only go so far. Getting an economy out of a deep depression, he argued, required fiscal policy measures such as government borrowing and deficit spending.

He also thought tax cuts could help, but he noted that people were likely to save some or all the money they gained rather than spend it. But he thought the government could address these problems by increasing taxes once prosperity returned. This was his big idea. Traditional economists argued against deficit spending and government intervention in the economy. They pointed out that in the long run the economy would correct itself. Older economists tended to defend free-market principles and warn about the dangers of government intervention in the private enterprise system.

Hayek, an Austrian free-market economist and harsh critic of socialism. When Keynes published his book in , the New Deal was operating in the U. Numerous government employment programs such as the Works Progress Administration WPA hired workers to construct government buildings, roads, and other public projects. Keynes calculated that the U. But the New Deal borrowed and spent far less. The government even raised taxes, further crippling consumer and investor demand.
