Market (economics)In economics, a market is a composition of systems, institutions, procedures, social relations or infrastructures whereby parties engage in exchange. While parties may exchange goods and services by barter, most markets rely on sellers offering their goods or services (including labour power) to buyers in exchange for money. It can be said that a market is the process by which the prices of goods and services are established. Markets facilitate trade and enable the distribution and allocation of resources in a society.
Crisis theoryCrisis theory, concerning the causes and consequences of the tendency for the rate of profit to fall in a capitalist system, is associated with Marxian critique of political economy, and was further popularised through Marxist economics. Earlier analysis by Jean Charles Léonard de Sismondi provided the first suggestions of the systemic roots of Crisis. "The distinctive feature of Sismondi's analysis is that it is geared to an explicit dynamic model in the modern sense of this phrase ...
Effective demandIn economics, effective demand (ED) in a market is the demand for a product or service which occurs when purchasers are constrained in a different market. It contrasts with notional demand, which is the demand that occurs when purchasers are not constrained in any other market. In the aggregated market for goods in general, demand, notional or effective, is referred to as aggregate demand. The concept of effective supply parallels the concept of effective demand.
SavingSaving is income not spent, or deferred consumption. Methods of saving include putting money aside in, for example, a deposit account, a pension account, an investment fund, or as cash. Saving also involves reducing expenditures, such as recurring costs. In terms of personal finance, saving generally specifies low-risk preservation of money, as in a deposit account, versus investment, wherein risk is a lot higher; in economics more broadly, it refers to any income not used for immediate consumption.
Das KapitalCapital: A Critique of Political Economy (Das Kapital. Kritik der politischen Ökonomie), also known as Capital, is a foundational theoretical text in materialist philosophy and critique of political economy written by Karl Marx, published as three volumes in 1867, 1885, and 1894. The culmination of his life's work, the text contains Marx's analysis of capitalism, to which he sought to apply his theory of historical materialism "to lay bare the economic laws of modern society", following from classical political economists such as Adam Smith, Jean-Baptiste Say, David Ricardo and John Stuart Mill.
Say's lawIn classical economics, Say's law, or the law of markets, is the claim that the production of a product creates demand for another product by providing something of value which can be exchanged for that other product. So, production is the source of demand. In his principal work, A Treatise on Political Economy (Traité d'économie politique, 1803), Jean-Baptiste Say wrote: "A product is no sooner created, than it, from that instant, affords a market for other products to the full extent of its own value.
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.
Thomas Robert MalthusThomas Robert Malthus (ˈmælθəs; 13/14 February 1766 – 29 December 1834) was an English economist, cleric, and scholar influential in the fields of political economy and demography. In his 1798 book An Essay on the Principle of Population, Malthus observed that an increase in a nation's food production improved the well-being of the population, but the improvement was temporary because it led to population growth, which in turn restored the original per capita production level.
General glutIn macroeconomics, a general glut is an excess of supply in relation to demand, specifically, when there is more production in all fields of production in comparison with what resources are available to consume (purchase) said production. This exhibits itself in a general recession or depression, with high and persistent underutilization of resources, notably unemployment and idle factories. The Great Depression is often cited as an archetypal example of a general glut.
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.
