Keynesian Model | Vibepedia

The Keynesian model, pioneered by [[john-maynard-keynes|John Maynard Keynes]], fundamentally altered macroeconomic theory by positing that aggregate demand, not just supply, drives economic output and employment in the short run. It challenges the classical notion of self-correcting markets, arguing that economies can get stuck in recessions due to insufficient demand, necessitating government intervention. Key tenets include sticky prices and wages, the multiplier effect, and the role of fiscal policy in stabilizing business cycles. Emerging from the ashes of the Great Depression, the model provided a theoretical justification for government spending and monetary policy interventions, influencing economic policy for decades, though it has faced significant critiques and evolutions, notably with the rise of [[new-keynesian-economics|New Keynesian economics]]. Its enduring legacy lies in its focus on the real-world impact of economic fluctuations and the potential for policy to mitigate them.
