What Is Demand-Side Economics?

Keynesian economists believe that the primary factor driving economic activity and short-term fluctuations is the demand ꦍfor goods and services. The theory i🐈s sometimes called demand-side economics.

This perspective is at odds with classical economic theory, or supply-side economics, which states that the production of goods or services, or supply, is of primary importance in economic growth.

Key Takeaways

  • Demand-side economics refer to the theory that the demand for goods and services drives economic activity.
  • A core characteristic of demand-side economics is aggregate demand.
  • Governments can generate demand for goods and services if people and businesses are unable to spend.
  • Economist John Maynard Keynes developed his economic theories during the Great Depression of the 1930s.
  • Keynes believed that a government should increase spending to spur subsequent spending by consumers and businesses in times of depressed economic activity.

Understanding Demand-Side Economics

Keynes maintained that unemployment is the result of inadequate demand for goods. During the 澳洲幸运5官方开奖结果体彩网:Great Depression, factories sat idle. Due to a lack of demand for produc﷽ts, factories had insufficient need for workers.

This lack of 澳洲幸运5官方开奖结果体彩网:aggregate demand contributed to unemployment and, contrary to classical 🦹theories of economics, the economy was not able to self-correct and restore balance.

One of the core characteristics of 澳洲幸运5官方开奖结果体彩网:Keynesian economics or demand-side economics is the emphasis on aggregate demand. Aggregate demand is composed of four elements: consumption of goods and services; investment by industry in 澳洲幸运5官方开奖结果体彩网:capital goods; government spending on public goods𝔉 and services; 🧔and net exports.

Under the demand-side model, Keynes advocated for government intervention to help overcome low aggregate demand in the short term, such as during a 澳洲幸运5官方开奖结果体彩网:recession or depression. This could reduce unemployment and st🃏imulate economic growth.

John Maynard Keynes

Economist 澳洲幸运5官方开奖结果体彩网:John Maynard Keynes developed his economic theories in part as a response to the Great Depression of the 1930s. Before the Great Depression, 澳洲幸运5官方开奖结果体彩网:classical economics was the dominant theory. It held that through the market forces of&ꦡnbsp;supply and demand, economic equilibrium would be restored naturally over time.

However, Keynes believed that the Great Depression and its lo🌺ng-running, widespread unemployment defied classical economic theories. His theories tried to explain why the mechanisms of the free market were not restoring balance to the economy.

Keynes' book, "The General Theory of Employment, Interest, and Money", was written in 1936 and reflected his experience as a witness to the Great Depression. In it, he rejects the aforementioned belief that an economy in a downturn would right itself. Instead, he believed that action by the government was called for. It should intervene with increased spending and lower taxes to stimulate consumption.

Types of Demand-Side Economic Policies

Government Spending

If the other components of aggregate demand are static, government spending can help. If people are less able or willing to consu🐭me, and businesses are less willing to hire workers and invest in building more factories, the government can step in. It can increase government spending to generate demand for goods and services.

Keynesian economics supports heavy government spending during a national recession to encourage economic activity. Putting more money in the pockets of the middle and lower classes has a greater benefit to the economy than saving or stockpiling the money in a wealthy person's account.

Increasing the Money Supply

Central banks can also achieve this goal by altering interest rates or selling or buying government-issued bonds. This type of intervention is part of what is known as monetary policy. These actions, such as changing 澳洲幸运5官方开奖结果体彩网:interest rates, can be used to increase the total 澳洲幸运5官方开奖结果体彩网:money supply in the economy or the 澳洲幸运5官方开奖结果体彩网:velocity of money flowing through the economy.

Increasing the flow of money correspondingly increases the velocity of money, or the frequency at which $1 is used to buy domestically-produced goods and services. Increased velocity of money means more people are consuming goods and services and, thus, contributing to an 🌌increase in aggregate demand.

Example of Demand-Side Economic Policies

The financial crisis of 2008 sparked the use of demand-side economic policy by the U.S. government. The Obama administration lowered interest rates. It also cut taxes for the middle class and put together a $787 billion stimulus package. What's more, the government intervened to overhaul the financial industry in a way not seen since the days of Franklin D. Roosevelt in the 1930s.

What Is Demand-Side Economics?

Demand-side economics is another name for Keynesian economic theory. It states that the demand for goods and services isꦉ the force behind h🎉ealthy economic activity.

How Are Supply-Side and Demand-Side Economics Different?

Demand-side economics holds that demand for goods and services drives economic growth. Supply-side economics (also 澳洲幸运5官方开奖结果体彩网:known as classical economic theory) states thaওt the production of goods a🦄nd services is the main force driving economic growth. Demand refers to spending on goods. Supply refers to the production of goods.

Who Was John Maynard Keynes?

John Maynard Keynes was an English economist who became known for his macroeconomic theory of demand-side economics in the 1930s. It became known as Keynesian economics. He pushed for policies that increased government spendin🌳g and decreased taxes, which he believed would stimulate demand for products and services during the Great Depression.

The Bottom Line

Demand-side economics asserts that the lack of aggregate demand in an economy contributes to unem🅺ployment which leaves it unable to self-correct and restore balance. The theory runs contrary to classical theories of economics by promoting the use of government spending to aid the economy in times of recession.
