32.1 The Great Depression and Keynesian Economics

It is hard to imagine that anyone who lived during the Great Depression was not profoundly affected by it. Some 85, businesses failed. Hundreds of thousands of families lost their homes. By , about half of all mortgages on all urban, owner-occupied houses were delinquent Wheelock, The economy began to recover after , but a huge recessionary gap persisted.

Income and employment theory

It caused 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.

An economic theory based on the ideas of John Maynard Keynes — , developed in the s, that assigned an important role to the state as well as to the private sector. Central elements of this theory are the failure of prices, especially wages, to adjust to clear markets; and the effect of changes in aggregate demand on real output and employment. Keynesian economics asserts that aggregate demand is the driving force in the economy; in particular, during a recession the government can boost economic activity by increasing its spending, thereby inducing private consumption and investment. Post Keynesian economics, which prevailed in the s and s, emphasized the role of uncertainty, path dependence, and the effects of money on the real economy. From the early s the ideas of Keynes have been further developed in New Keynesian economics which endeavours to derive them from microfoundations, in particular, assuming rational expectations for the economic agents. The IS—LM model combines the national income identity with simple behavioural rules to determine the values of output and interest rate that imply simultaneous equilibrium on the product and money markets. This equilibrium is obtained assuming fixed real wages, so the labour market can be out of equilibrium.

According to Keynes, employment can be increased by increasing consumption and/or investment. Consumption depends on income C(Y) and when income rises.

Keynesian economics

In the Keynesian theory, employment depends upon effective demand. Effective demand results in output. Output creates income.

It believes that the government should have a balanced budget and incur little debt. Consumers would save today to pay off future debt. The neoclassical growth theory is an economic concept where equilibrium is found by varying the labor amount and capital in the production function. The Keynesian theory is strictly short-run economics.

Income and employment theory , a body of economic analysis concerned with the relative levels of output, employment, and prices in an economy. By defining the interrelation of these macroeconomic factors, governments try to create policies that contribute to economic stability.

mcq on theory of income and employment

Effective demand refers to the willingness and ability of consumers to purchase goods at different prices. It shows the amount of goods that consumers are actually buying — supported by their ability to pay. Effective demand excludes latent demand — where the willingness to purchase goods may be limited by the inability to afford it — or lack of knowledge.

In this situation, the classical theorists believe that prices and wages will fall, reducing producer costs and increasing the supply of real GDP until it is again equal to the natural level of real GDP. Sticky prices. Keynesians, however, believe that prices and wages are not so flexible. They believe that prices and wages are sticky , especially downward. The stickiness of prices and wages in the downward direction prevents the economy's resources from being fully employed and thereby prevents the economy from returning to the natural level of real GDP. Recall that real GDP can be decomposed into four component parts: aggregate expenditures on consumption, investment, government, and net exports.
