Crisis theory
Crisis theory, within Marxist economics, examines the recurrent economic downturns of capitalism as manifestations of its internal contradictions, particularly the tendency of the rate of profit to fall due to rising organic composition of capital and overproduction exceeding effective demand.[1][2] Originating in Karl Marx's analyses in Capital and related manuscripts, it posits crises as inevitable disruptions that temporarily restore profitability through destruction of capital and labor but ultimately exacerbate contradictions like class antagonism and uneven development.[3][4] Key concepts include the law of the tendency of the rate of profit to fall, driven by capitalists' substitution of machinery for labor, which increases constant capital relative to value-creating variable capital, alongside counteracting factors such as cheaper inputs and market expansion.[1][5] The theory has influenced interpretations of historical crises, including the Long Depression of the 1870s, the Great Depression of the 1930s, the stagflation of the 1970s, and the 2008 financial meltdown, which empirical records confirm as periodic contractions in output, employment, and trade under capitalist systems.[6][7] Debates persist among proponents on primary triggers—profitability decline versus underconsumption or disproportionality—and on empirical validation, with some studies finding support for falling profitability trends amid countertendencies like technological innovation, while critics highlight capitalism's resilience through institutional adaptations and global expansion, challenging predictions of terminal collapse.[8][9] Despite these controversies, crisis theory underscores causal mechanisms rooted in accumulation dynamics rather than exogenous shocks, informing analyses of contemporary instabilities like debt accumulation and financialization.[10][11]
