phenomenon in which greater input of effort, money, etc. yields smaller results. Crucial part of the idea is that if you're using x to get y results (where y is the thing you want). then additional input a will yield additional results b, but not in the same proportion as before.
On average, before, you put in x to get y, so your yield was y/x. But if you increase x by amount a, then your results will be y + b, where
(y + b)/(x + a) < y/x
and this will only get worse.
Diminishing marginal returns (DMR) is used to explain why the supply curve in economics slopes upward, i.e., increasing the quantity supplied requires an increased price of most things.
Sometimes DMR is more than offset by "economies of scale," which allows more of a thing to be supplied more cheaply than a small amount.

At first his flowers and treats swept her off her feet, but then he had to do more and more lavish things to please her. It was a classic case of diminishing marginal returns.

potentially any association of people with a common set of goals, who are politically active as such. However, pressure groups are usually understood to be more grassroots and issue-oriented, rather than interest-oriented (so they are not quite the same as a lobby). Hence, pressure groups are likely to include groups opposed to human rights violations and neighborhood "renewal" projects.
The London-based pressure group, Survival International, called on oil companies to immediately withdraw from Peru, describing the incident as "the Amazon's Tiananmen" and accusing security forces, who have since imposed a curfew over the region, of burying and burning corpses to hide the scale of the killing.
"Peruvian Indians are being driven to desperate measures to try to save their lands which have been stolen from them for five centuries," said the director of Survival, Stephen Corry. "This is the Amazon's Tiananmen. If it finishes the same way, it will also end Peru's international reputation."

*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.

(FINANCE) the increase in wealth that goes to the owner of a financial asset when it increases in value. If you buy a share of stock, and the share increases in value, then you have capital gains whether you have sold it or not.
If you sell the stock at the higher price, you have made money on the transaction and have "realized capital gains." If you hang onto the asset in the hopes its value will increase even more, you have "unrealized capital gains."

For owners of stocks, wealth can come in the form of capital gains or dividends. For owners of gold, the only benefit comes from capital gains. This is why gold is usually not a good investment.

(FINANCE) real estate mortgage backed securities; usually used to refer to the derivatives created by Fannie Mae and Freddie Mac that were used to create collateralized debt obligations CDO's.
Most economists seem to agree that the 2008 crisis was caused by the collapse of the real estate market, which was mainly caused by the toxic relationship between RMBS's and the CDO's created mostly with them.

For almost eighty years the RMBS business helped people buy homes, with few serious problems. Then Congress abolished Glass-Steagall, the banks merged and created CDO's, and total disaster followed.
