Marxian economicsMarxian economics, or the Marxian school of economics, is a heterodox school of political economic thought. Its foundations can be traced back to Karl Marx's critique of political economy. However, unlike critics of political economy, Marxian economists tend to accept the concept of the economy prima facie. Marxian economics comprises several different theories and includes multiple schools of thought, which are sometimes opposed to each other; in many cases Marxian analysis is used to complement, or to supplement, other economic approaches.
Historical materialismHistorical materialism is Karl Marx's theory of history. Marx locates historical change in the rise of class societies and the way humans labor together to make their livelihoods. For Marx and his lifetime collaborator, Friedrich Engels, the ultimate cause and moving power of historical events are to be found in the economic development of society and the social and political upheavals wrought by changes to the mode of production. It provides a challenge to the view that historical processes have come to a close and that capitalism is the end of history.
UnderconsumptionUnderconsumption is a theory in economics that recessions and stagnation arise from an inadequate consumer demand, relative to the amount produced. In other words, there is a problem of overproduction and overinvestment during a demand crisis. The theory formed the basis for the development of Keynesian economics and the theory of aggregate demand after the 1930s. Underconsumption theory narrowly refers to heterodox economists in Britain in the 19th century, particularly from 1815 onwards, who advanced the theory of underconsumption and rejected classical economics in the form of Ricardian economics.
OverproductionIn economics, overproduction, oversupply, excess of supply or glut refers to excess of supply over demand of products being offered to the market. This leads to lower prices and/or unsold goods along with the possibility of unemployment. The demand side equivalent is underconsumption; some consider supply and demand two sides to the same coin – excess supply is only relative to a given demand, and insufficient demand is only relative to a given supply – and thus consider overproduction and underconsumption equivalent.
Late capitalismLate capitalism, late-stage capitalism, or end-stage capitalism is a term first used in print by German economist Werner Sombart around the turn of the 20th century. In the late 2010s, the term began to be used in the United States and Canada to refer to corporate capitalism. Later capitalism refers to the historical epoch since 1940, including the post–World War II economic expansion. The expression already existed for a long time in continental Europe, before it gained popularity in the English-speaking world through the English translation of Ernest Mandel's book Late Capitalism, published in 1975.
Organic composition of capitalThe organic composition of capital (OCC) is a concept created by Karl Marx in his theory of capitalism, which was simultaneously his critique of the political economy of his time. It is derived from his more basic concepts of 'value composition of capital' and 'technical composition of capital'. Marx defines the organic composition of capital as "the value-composition of capital, in so far as it is determined by its technical composition and mirrors the changes of the latter".
Business cycleBusiness cycles are intervals of expansion followed by recession in economic activity. A recession is sometimes technically defined as 2 quarters of negative GDP growth, but definitions vary; for example, in the United States, a recession is defined as "a significant decline in economic activity spread across the market, lasting more than a few months, normally visible in real GDP, real income, employment, industrial production, and wholesale-retail sales.
Tendency of the rate of profit to fallThe tendency of the rate of profit to fall (TRPF) is a theory in the crisis theory of political economy, according to which the rate of profit—the ratio of the profit to the amount of invested capital—decreases over time. This hypothesis gained additional prominence from its discussion by Karl Marx in Chapter 13 of Capital, Volume III, but economists as diverse as Adam Smith, John Stuart Mill, David Ricardo and Stanley Jevons referred explicitly to the TRPF as an empirical phenomenon that demanded further theoretical explanation, although they differed on the reasons why the TRPF should necessarily occur.
Financial crisisA financial crisis is any of a broad variety of situations in which some financial assets suddenly lose a large part of their nominal value. In the 19th and early 20th centuries, many financial crises were associated with banking panics, and many recessions coincided with these panics. Other situations that are often called financial crises include stock market crashes and the bursting of other financial bubbles, currency crises, and sovereign defaults.
Long DepressionThe Long Depression was a worldwide price and economic recession, beginning in 1873 and running either through March 1879, or 1896, depending on the metrics used. It was most severe in Europe and the United States, which had been experiencing strong economic growth fueled by the Second Industrial Revolution in the decade following the American Civil War. The episode was labeled the "Great Depression" at the time, and it held that designation until the Great Depression of the 1930s.
