Why does capitalism have business cycles?

Capitalism experiences business cycles due to fluctuations in economic activity driven by factors like consumer demand, investment levels, and external shocks. These cycles typically consist of periods of expansion, where economic activity and employment rise, followed by contractions or recessions, marked by reduced spending and increased unemployment. Additionally, changes in monetary policy, technological advancements, and market speculation can amplify these cycles. Overall, the dynamic nature of supply and demand, along with human behavior, contributes to the inherent instability of capitalist economies.
