*noun*; in Keynesian economics, the rate at which aggregate consumption rises in response to a rise in national income.
For example, suppose the marginal propensity to consume (MPC) is 0.95. If the national income is 100 billion dollars, and it rises 10%, then consumption will rise by 9.5 billion, and saving will rise by 0.5 billion.
If this theory is correct, then an expanding economy will suffer insufficient demand for its own output, and a recession will be inevitable.
This is why national governments respond to recessions with deficit spending: they are trying to counteract the MPC's effect on aggregate demand, and bring it in line with potential output.

Not only is the marginal propensity to consume weaker in a wealthy community, but, owing to its accumulation of capital being already larger, the opportunities for further investment are less attractive...

*noun*; prolonged economic crisis characterized by drastic (i.e., >20%) decline in output, reduction in employment, and deflation. Other technical conditions include a liquidity trap and "permanent" (i.e., persisting in many sectors for several quarters) failure to reach equilibrium.
Usually the word "depression" (when referring to economics) is used to refer to the Great Depression, although in fact there were eight incidents of a global depression between 1815 and 1922. These were
--- 1815-21
--- 1832-33
--- 1837-44
--- 1854-57
--- 1867-68
--- 1876-79
--- 1893-96
--- 1920-22
In addition, there have been many localized depressions, panics (e.g., the 1907 Panic {USA}, followed by the Mexican Depression of 1908), and recessions.
DIFFERENCE BETWEEN RECESSION & DEPRESSION
The technical distinction between a recession and depression can vary, although economists usually agree on which is which. In Keynesian economics, a depression is defined by the existence of a flat liquidity-money (LM) curve (which means that interest rates have no influence on people's determination to hold their wealth as cash); and/or a nearly vertical investment-savings (IS) curve (which means interest rates have no influence on the willingness of entrepreneurs to expand/continue operations).
In contrast, a recession is a much less drastic event. Interest rates still have influence on investment and liquidity, and there is no deflation. Conventional fiscal policy and monetary policy, combined and in moderate doses, can restore full employment.
Neoclassical economics/New Classical economics defines a recession as a shift in people's income/leisure preferences as the result of a technology shock. The technology shock sharply reduces the returns to labor, so workers are paid less and many withdraw their labor from the market. In a depression, the technology shocks are compounded and cause a permanent change in the production function; large numbers of enterprise are no longer viable.
More generally, a recession involves the downward phase of a routine business cycle; these typically occur every three-seven years. A depression represents a partial collapse of the industrial system, and a comprehensive collapse of the financial system.

From 1929 to 1933 the U.S. price level fell 25 percent. Many economists blame this deflation for the severity of the Great Depression. They argue that the deflation may have turned what in 1931 was a typical economic downturn into an unprecedented *sic* period of high unemployment and depressed income.

*noun*; generic term for economic thought developed from 1776 to 1930, which assumed the following basic concepts:
1. all types of goods, including factors of production, can be efficiently traded in markets;
2. given free markets, all goods available for purchase will, in fact, be purchased (including labor);
3. free markets include unlimited ability of prices of commodities to move upwards or downward to ensure the quantity supplied matches the quantity demanded.
*Subdivisions*
Adam Smith (1723-1790), auther of *The Wealth of Nations* (1776) is usually credited with compiling the critical ideas into a single theory.
Some historians regard the classical era as really beginning after 1817, with the work of David Ricardo (1772-1823) and Nassau Senior (1790-1864). Ricardo and David developed the concept of diminishing marginal utility to explain the idea of factor cost, and ultimately, market equilibrium.
After 1870, however, classical economics experienced the marginal revolution, in which the field adopted a much more systematic approach to addressing major research questions.
As a result of the Great Depression (1929-1939), classical economics generally faded from view until the late 1970's. At this time, the rational expectations hypothesis and real business cycle theory were refined in order to address problems that had crippled classical economics in the 1920's.
Textbooks addressing classical economic research since 1964 usually call it "New Classical economics." From 1982 to 2006, nearly all Nobel prizes in economics were awarded to New Classical economics such as
George Stigler, Ronald Coase, Robert Lucas Jr., Edward Prescott, and Edmund Phelps.

Proponents of classical economics are nearly always extremely conservative in their political views, and usually conclude that the sole legitimate role of the state is to defend property rights.

A currency whose value is set by the currency markets; money whose exchange rate relative to other currencies is determined mainly or entirely by unrestricted trading in the currency. Most currencies are dirty float|dirty floats, which means that the government issuing them attempts to manage their traded value in some way; or else hard peg|hard pegs, in which the value is tied to something specific.
When a currency is floating, then its value may rise because the county is running a trade surplus, or it is running a capital account surplus. Floating currencies are not fiat money, although they are often confused for each other.

(MATHEMATICS) each positive number has another number that, when multiplied times itself, equals that number. So, for example, 4 has a square root of 2 (2 x 2 = 4).
The square root of a negative number is an imaginary number. Imaginary numbers are not, by themselves, useful solutions to math problems; but they can be used to find them.

BILL: Anna, we have a rectangle that's 3 x as long as it is wide, and it encloses an area of 300 square meters. What are the dimensions?
ANNA: Well, that's like 3 squares of 100 square meters. The square root of 100 is 10, so the rectangle is 10 by 30.
_________________________________________
The logarithm of a square root is one half the log of the number itself; hence, the natural log of 25 is 3.2189, while the natural log of 5 is 1.6094.

(US GOVERNMENT) one of two governing boards of the US Federal Reserve System (the Usonian Central Bank). The FRB consists of seven governors appointed by the White House to staggered terms of 14 years.
Governor appointments are subject to Senate confirmation.
The FRB sets monetary policy. Its seven members also serve on the other governing board of the Fed, the FOMC. However, the FRB has sole responsibility for discount rates and reserve requirements, and it is also responsible for enforcement of banking regulation.

Despite the fact that the Chairman of the Federal Reserve Board has the same power as the other six governors, most people have only heard of Alan Greenspan (1987-2006) or Ben Bernanke (2006-present). About the same time, Susan M. Phillips (1991-1998) held approximately equal power on the Board; so did Roger W. Ferguson, Jr. (1997-2006).
Because governors almost never serve their full terms, there are currently only five governors on the board. The two longest-serving members, Bernanke and Vice Chair Donald Kohn, have only been there since August 2002.

(ECONOMICS) survey of 60,000 households in the USA conducted monthly by the Bureau of Labor Statistics. One of two ways in which the BLS gathers statistics on unemployment and hours worked. The other is the establishment survey.
According to an analysis of the 2009 March Current Population Survey, one in five men ages 18-64 - about 21.2 million - are uninsured, compared with 17.2 million women in the same age group. This gap in coverage is consistent across various demographic groups.
