Key Differences
Classical economic theory is rooted in the idea that free markets can regulate themselves if left alone. It asserts that if there's a demand, supply will meet it, ensuring full employment and stable prices. Keynesian economics, proposed by John Maynard Keynes, counters this by emphasizing the inherent instabilities in markets, which can lead to prolonged periods of high unemployment and fluctuating prices.
The Classical perspective believes that any deviation from full employment will be self-correcting. In this view, if the economy experiences a downturn, wages will decrease, making it cheaper for businesses to hire, thereby restoring full employment. In contrast, the Keynesian view posits that wages and prices can be sticky, preventing the self-correcting mechanism proposed by classical economists. Keynesians believe government can play a role in smoothing out economic fluctuations through fiscal and monetary policies.
Furthermore, Classical economics assumes savings will always equal investment, meaning the total amount saved will equal the total amount invested in new business ventures. However, Keynesian theory highlights that during a recession, pessimism can lead to reduced investment, despite ample savings. This disparity can exacerbate economic downturns.
To summarize, while Classical economics emphasizes the self-regulating nature of markets and minimal government intervention, Keynesian economics underscores the occasional need for government intervention to stabilize the economy, especially during recessions.
