Which economic model best explains short-term behavior, and which one is more applicable to long-term behavior?

Explanation

The Keynesian model primarily addresses short-run economic fluctuations, focusing on factors like aggregate demand that influence short-term output and employment. In contrast, the classical model is centered on long-run outcomes where markets clear, and supply determines economic variables. Therefore, the Keynesian approach is suitable for analyzing short-term behavior, while the classical model explains long-run economic behavior.
