What is The Keynesian Theory?

Summary

The video discusses Keynesian economics, a theory developed by British economist John Maynard Keynes during the 1930s to address the Great Depression. Keynes advocated for increased government spending and lower taxes to stimulate demand and boost the economy. Unlike classical economics, which believed the market would self-correct through lower wages and prices, Keynesian theory argues that government intervention is necessary to influence demand and prevent economic slumps. The theory highlights how weak demand can prevent businesses from investing or hiring, worsening economic downturns.

Q & A

Who developed Keynesian economics and during which period?

Keynesian economics was developed by British economist John Maynard Keynes during the 1930s in response to the Great Depression.

What is the core idea behind Keynesian economics?

The core idea of Keynesian economics is that optimal economic performance can be achieved by influencing aggregate demand through government intervention, such as increased public spending and reduced taxes.

How did classical economics differ from Keynesian economics regarding cyclical swings in the economy?

Classical economics believed that cyclical swings in employment and output were self-adjusting, and that falling demand would lead to lower wages and prices, eventually restoring equilibrium. In contrast, Keynesian economics argued that this self-correction could fail due to weak demand.

What did Keynes argue about lower wages and full employment?

Keynes argued that lower wages would not restore full employment because employers wouldn't hire more workers to produce goods if there was insufficient demand for those goods.

According to Keynes, how might poor business conditions affect investment?

Poor business conditions may cause companies to reduce capital investment, as they may be reluctant to invest in new plant and equipment even if prices are lower, due to weak demand and uncertain economic conditions.

What role does government intervention play in Keynesian economics?

In Keynesian economics, government intervention, such as increased spending and tax cuts, is crucial for stimulating demand and pulling the economy out of a downturn.

Why did Keynes believe that falling prices and wages might not boost economic recovery?

Keynes believed that falling prices and wages would not necessarily boost recovery because weak demand would still limit production and investment, preventing businesses from expanding employment.

How did Keynesian economics respond to the classical theory's approach to economic slumps?

Keynesian economics rejected the classical theory's reliance on self-adjustment of prices and wages during slumps, advocating instead for government intervention to boost demand and support recovery.

What is meant by 'aggregate demand' in Keynesian theory?

Aggregate demand refers to the total demand for goods and services within an economy. In Keynesian theory, managing aggregate demand through fiscal policies is essential for stabilizing the economy.

What effect does Keynesian theory suggest economic intervention would have during a recession?

Keynesian theory suggests that economic intervention, such as government spending and lower taxes, can increase aggregate demand and reduce the severity of a recession by boosting employment and production.
