Keynesian economics
An economic theory asserting that government spending and fiscal policy can stimulate economic activity during recessions, overcoming deficiencies in private sector demand.
Example
“Keynesian economics justified the 2009 stimulus package — government spending would offset the collapse in private sector demand.”
Memory Tip

Why It Matters
Understanding Keynesian economics helps you anticipate how government policies during economic downturns might affect inflation, interest rates, and job availability. This knowledge allows you to make better decisions about saving, investing, and spending during different phases of the economic cycle.
Common Misconception
Many people believe Keynesian economics means the government should always spend more money to help the economy. In reality, Keynesian theory suggests government intervention is most effective during recessions when private spending has collapsed, not during periods of healthy economic growth.
In Practice
During the 2008 financial crisis, the U.S. government implemented a stimulus package of approximately 831 billion dollars in spending and tax cuts. This injection of government money aimed to prevent further economic collapse by maintaining consumer spending and preventing massive job losses when private businesses had stopped investing.
Etymology
Named after British economist John Maynard Keynes (1883-1946), who developed the theory during the Great Depression.
