Interest rates keynesian theory

K eynesian economics is a theory of total spending in the economy called aggregate demand and its effects on output and inflation. Although the term has been used and abused to describe many things over the years, six principal tenets seem central to Keynesianism. The first three describe how the economy works. A Keynesian believes that aggregate demand is influenced by a host of economic decisions—both public and private—and sometimes behaves erratically.

Keynesian Economics

Keynesian economics, developed by John Maynard Keynes, is considered one of the most influential approaches to economic thought. While many economists have changed, altered, and argued Keynes views, Keynesian economics has had a lasting impression on the field. In the wake of the latest recession, Keynesian thought has experienced a resurgence among prominent economic figures and policy makers.

He grew up in Cambridge, England where his father taught at the university. He was interested in both mathematics and philosophy, which led him eventually to find his true calling in the field of economics.

In , Keynes published The Economic Consequences of the Peace in which he predicted the high inflation and economic stagnation in Europe as a result of the reparations imposed on Germany following the First World War. The work also stressed the relationships between various government controls and inflation, and correctly anticipated the rise of Fascism in Europe.

Now considered a prominent economist himself, Keynes became interested in monetary theory. As his studies continued, Keynes became increasingly skeptical of the conclusions of classical economic theory and of the classical dichotomy. His research in monetary theory convinced him that finance could affect the real side of the economy.

Keynes thus set out to explain the Great Depression using this line of thinking. In , he published The General Theory of Employment, Interest, and Money , concisely known as The General Theory , which arguably became one of the most influential writings of modern economic theory. The General Theory focuses on refuting the classical conclusions that employment is determined by the price of labor, and proposes that employment is actually determined by spending, or aggregate demand.

Keynes argues that under-full employment equilibria exist, unlike the classical claim that if the economy is not at full employment, it will reach full employment eventually.

Keynes argues that investment need not equal savings, since investment is a function of the expected rate of return as well as the interest rate. An increase in saving may lower the interest rate and provide an incentive for investment to rise, but if the expected rate of return is low investment will not rise in proportion to saving. Consequently, the level of aggregate demand will fall, and the insufficient demand will cause an equilibrium with less than full employment.

Given the propensity to consume and level of employment, Keynes argues an equilibrium exists where aggregate demand equals aggregate supply. Consumption is largely dependent on income, because as income increases people are willing and able to consume more.

Furthermore, increased investment leads to increased income. Keynes argues that consumption will always be less than income, but never be negative. Instead they will spend some fraction of it, putting part of the increased income back into the economy. The increased income leads to more consumption, which will raise GDP. The Classicals said that interest was determined through the interaction between the supply and demand of saving, but Keynes refuted this saying that interest rates are determined by the supply and demand for money.

He argued that savings and investment were much more inelastic than originally hypothesized by the classicals. Money, he argued, was much more responsive to periods of excessive saving, and would allow faster changes in the interest rate. Because of substitution and income effects on saving, and long-term expectations on investment, the supply and demand of saving, Keynes argued, were not an accurate explanation for how the interest rate adjusts.

The interest rate has an obvious effect on the economy because as the interest rate increases, it becomes more expensive to borrow. Individuals will borrow less, resulting in decreased consumption and decreased overall income. As the interest rate rises, Keynes argues that consumer spending and investment will also fall.

For these reasons, Keynes opposed a laissez-faire approach to regulating the macro-economy, and supported federal stimulus in times of recession. The Keynesian view of the world was articulated by Sir John Hicks in the IS-LM model, which became the macroeconomic model used by policy makers for the next few decades.

The LM curve represents equilibria in the money market—all combinations of interest rates and real income where money supply equals money demand. If the government increases its spending, the IS curve will shift to the right. This increases GDP as well as interest rates. Keynes believes that, assuming the economy is operating at less than full employment, increased government spending is good for the economy because it encourages private investment through the accelerator effect.

The accelerator effect says that an increase in GDP leads to an increase in investment, which leads to a further increase in GDP. The Classicals said that increased saving would decrease consumption, but interest rates would also decrease and investment would adjust so that the total aggregate spending would be the same.

Keynes said that spending does affect GDP. Increased spending leads to increased production, which increases aggregate demand, which affects GDP. He says that people are pessimistic about the future and hold on to their money; as a result it does not flow into financial markets. Because hoarding exists, the interest rate does not affect investment enough to offset consumer saving, therefore aggregate demand can fall and GDP is not always at full potential.

The government needs to spend money to jump start the economy. Keynesian and modern revisions of Keynesian thought continue to influence macro-economic policy today.

Only two years later he had devised the theory of liquidity preference. Keynes saw that the long-term rate of interest was not a reward for saving. wiacek.com.au › publ › bppdf.

The central tenet of this school of thought is that government intervention can stabilize the economy.

He asserts that it is applicable generally in all economic circumstances. Classical concepts, on the other hand, operate only in those rare "special" circumstances where full employment is possible. However, it is Keynesian theory that - if applicable at all - is applicable only in very narrow circumstances - like the "special" circumstances of the depths of the Great Depression where political leaders proved incapable of reforming the fundamental policy stupidities that prevented recovery.

What is Keynesian Economics?

It created a profound shift in economic thought, giving macroeconomics a central place in economic theory and contributing much of its terminology [1] — the " Keynesian Revolution ". It had equally powerful consequences in economic policy, being interpreted as providing theoretical support for government spending in general, and for budgetary deficits, monetary intervention and counter-cyclical policies in particular. It is pervaded with an air of mistrust for the rationality of free-market decision making. Keynes denied that an economy would automatically adapt to provide full employment even in equilibrium, and believed that the volatile and ungovernable psychology of markets would lead to periodic booms and crises. The General Theory is a sustained attack on the classical economics orthodoxy of its time. It introduced the concepts of the consumption function , the principle of effective demand and liquidity preference , and gave new prominence to the multiplier and the marginal efficiency of capital. The central argument of The General Theory is that the level of employment is determined not by the price of labour, as in classical economics , but by the level of aggregate demand. If the total demand for goods at full employment is less than the total output, then the economy has to contract until equality is achieved.

Liquidity preference , in economics, the premium that wealth holders demand for exchanging ready money or bank deposits for safe, non-liquid assets such as government bonds. As originally employed by John Maynard Keynes , liquidity preference referred to the relationship between the quantity of money the public wishes to hold and the interest rate.

The essential element of Keynesian economics is the idea the macroeconomy can be in disequilibrium recession for a considerable time. To help recover from a recession, Keynesian economics advocates higher government spending financed by government borrowing to kickstart an economy in a slump. Classical theory suggested any fall in investment would lead to lower interest rates; this fall in interest rates would reduce saving, increase investment and cause the economy to return to a new equilibrium of full employment. According to classical economic theory, labour markets should clear. In this model, any unemployment is due to wages being artificially kept above the equilibrium through minimum wages e. However, Keynes argued this was unsatisfactory. It is this macro perspective on savings and labour markets that led to the creation of macroeconomics. This stated that supply creates demand. However, Keynes believed the opposite was true. Keynes argued — demand determines the level of national output. Keynes was critical of the UK budget, which cut wages for hospital workers, and cut back spending on roads and new houses. He argued this would depress demand further and make the recession worse. Instead, he advocated higher government spending financed by higher borrowing.

Keynesian economics

Keynesian economics is an economic theory of total spending in the economy and its effects on output and inflation. Keynesian economics was developed by the British economist John Maynard Keynes during the s in an attempt to understand the Great Depression. Keynes advocated for increased government expenditures and lower taxes to stimulate demand and pull the global economy out of the depression. Subsequently, Keynesian economics was used to refer to the concept that optimal economic performance could be achieved—and economic slumps prevented—by influencing aggregate demand through activist stabilization and economic intervention policies by the government. Keynesian economics is considered a "demand-side" theory that focuses on changes in the economy over the short run. Keynesian economics represented a new way of looking at spending, output, and inflation. Previously, classical economic thinking held that cyclical swings in employment and economic output would be modest and self-adjusting. According to this classical theory, if aggregate demand in the economy fell, the resulting weakness in production and jobs would precipitate a decline in prices and wages. A lower level of inflation and wages would induce employers to make capital investments and employ more people, stimulating employment and restoring economic growth. The depth and severity of the Great Depression, however, severely tested this hypothesis.
