The Overproduction Theory of the Business Cycle Originated with Socialist Thinkers

The overproduction theory of the business cycle originated with socialist thinkers or those who leaned in that direction and was advocated by such individuals as Thomas Malthus, the nineteenth-century Swiss socialist J. C. L. de Sismondi, and Karl Marx. This theory says recessions and depressions occur because capitalism is characterized by periods of too much production. During these periods of excess production, businesses begin to accumulate inventory, cannot sell the inventory at profitable prices, and must cut back on production. The cutback in production leads to workers being laid off, factories being shut down, and causes a general decline in business activity. Hence, recessions and depressions result from overproduction in the free market.

Employment and production increase only after the inventories of businesses have been depleted sufficiently to make production profitable once again. So the economy goes back and forth between these periods of overproduction and production, in an endless cycle.

The specific reasons why it is said capitalists periodically produce too much vary, but it is generally based on the belief that the need and desire for goods is limited and the rapidly expanding production in a capitalist society inherently leads to the supply of goods outstripping the limited need and desire. If the need and desire for goods is less than the supply, then of course the demand will also be insufficient to purchase all the goods produced. Hence, production is periodically reduced back down to the demand for goods in recurring recessions and depressions.
