Keynesian economics is a macroeconomic theory developed by British economist John Maynard Keynes in the early 20th century. It presents a different perspective on economic management compared to classical economics. Keynesian economics emphasizes the importance of aggregate demand in influencing economic activity. It states that fluctuations in aggregate demand can lead to periods of economic instability, such as recessions or depressions. To address this, Keynesian economics suggests that government intervention through fiscal policy, such as increasing government spending or reducing taxes, can help stimulate demand and boost economic growth.

One of the key characteristics of Keynesian economics is the belief in the multiplier effect. The multiplier suggests that an increase in government spending will have a greater impact on overall economic output, as it leads to increased income and consumption, which in turn generates more spending and further economic growth. Another characteristic of Keynesian economics is the importance of active monetary policy. Keynes argued that monetary authorities should adjust interest rates and money supply to influence borrowing costs and investment levels. By reducing interest rates, Keynesian economics aims to encourage borrowing, investment, and spending, thereby stimulating economic activity. Keynesian economics also highlights the role of expectations and animal spirits in shaping economic behaviour. Keynes believed that individuals' subjective expectations about the future can significantly impact their decisions to spend, save, or invest.

One of the advantages of Keynesian economics is its ability to address short-term economic crises. By using fiscal and monetary policy tools, governments can intervene to mitigate the effects of recessions and stabilize the economy. This approach is particularly useful during periods of high unemployment and low aggregate demand. Moreover, Keynesian economics places importance on income distribution and social welfare. It recognizes the need for government intervention to reduce income inequality and provide a safety net for vulnerable individuals through measures like progressive taxation and social welfare programs.

The main difference between classical and Keynesian economics lies in their policy recommendations. Classical economics advocated for a laissez-faire approach with limited government intervention. Classical economists believed that markets would naturally self-adjust and return to equilibrium without external interference. While classical economics favours limited government involvement and relies on the self-regulating nature of markets, Keynesian economics supports active government intervention to stabilize the economy, especially during times of crisis.
