General glut

In 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. The term dates to the beginnings of classical economics in the late 18th century, and there is a long-running debate on the existence, causes, and solutions of a general glut. Some classical and neoclassical economists argue that there are no general gluts, advocating a form of Say's law (conventionally but controversially phrased as "supply creates its own demand"), and that any idling is due to misallocation of resources between sectors, not overall, because overproduction in one sector necessitates underproduction in others, as is demonstrable in severe price falls when such alleged 'malinvestment' in gluts clear; unemployment is seen as voluntary, or a transient phenomenon as the economy adjusts. Others cite the frequent and recurrent economic crises of the economic cycle as examples of a general glut, propose various causes and advocate various solutions, most commonly fiscal stimulus (government deficit spending), a view advocated in the 19th and early 20th century by underconsumptionist economists, and in the mid to late 20th and 21st century by Keynesian economics and related schools of economic thought. One can distinguish between those who see a general glut (greater supply than demand) as a supply-side issue, calling it overproduction (excess production), and those who see it as a demand-side issue, calling it underconsumption (deficient consumption). Some believe that both of these occur, such as Jean Charles Léonard de Sismondi, one of the earliest modern theorists of the economic cycle.

Paradox of thrift

The paradox of thrift (or paradox of saving) is a paradox of economics. The paradox states that an increase in autonomous saving leads to a decrease in aggregate demand and thus a decrease in gross output which will in turn lower total saving. The paradox is, narrowly speaking, that total saving may fall because of individuals' attempts to increase their saving, and, broadly speaking, that increase in saving may be harmful to an economy. The paradox of thrift is an example of the fallacy of composition, the idea that what is true of the parts must always be true of the whole.

Great Depression

The Great Depression (19291939) was an economic shock that impacted most countries across the world. It was a period of economic depression that became evident after a major fall in stock prices in the United States. The economic contagion began around September 1929 and led to the Wall Street stock market crash of October 24 (Black Thursday). It was the longest, deepest, and most widespread depression of the 20th century. Between 1929 and 1932, worldwide gross domestic product (GDP) fell by an estimated 15%.

Say's law

In 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.
