Economic Cycles

Economic cycles, also called business cycles, are recurring fluctuations in economic activity marked by phases of expansion, peak, contraction, and recovery, with consequences for employment, income, and social life. Karl Marx argued that capitalism is prone to periodic crises arising from overproduction and falling profit rates, and Joseph Schumpeter linked cycles to waves of innovation and creative destruction. Nikolai Kondratiev proposed long waves of roughly fifty years, and John Maynard Keynes explained downturns through insufficient aggregate demand, justifying state intervention. Hyman Minsky’s financial instability hypothesis described how stability encourages risk-taking that leads to crisis, and Karl Polanyi examined the social damage of unregulated markets. Sociologists study the human costs of cycles. Emile Durkheim noted that economic upheavals affect suicide rates, and Glen Elder’s research on children of the Great Depression showed how hardship shapes life courses. Giovanni Arrighi examined long cycles of capital accumulation, and Wolfgang Streeck analyzed how states have managed crises through debt. Recessions often deepen inequality, hitting young, low-paid, and minority workers hardest. Economic cycles remain central to research on labor markets, inequality, austerity, financialization, and political economy.
