The ability of an economic system to provide what people what, given their incomes. Given the fact that incomes and resources are both finite, efficiency will be of the utmost importance in determining if people's wants are satisfied by the workings of the economic system.
Free market economies usually provide high levels of economic efficiency.

a false allegation of murder; the term refers specifically to a recurring rumor from 12th century Europe that Jews were kidnapping Christian children and using their blood for ritual purposes. A famous example of the blood libel is recounted in the "Nun Prioress's Tale" from Chaucer's *Canterbury Tales*. In this and other versions of the story, the events are absurd and feature perverse miracles.
Frequently occurrences of the blood libel were accompanied by a wave of mass murder of Jewish residents of the city. In many cases, the zealots would force the authorities to try random Jews for the alleged crime; these trials were, naturally, travesties.
The last case of a blood libel resulting in murder was the Kielce pogrom of 1946. 200 Jewish survivors of the Final Solution were being transported back to Poland when a boy (who had disappeared for a couple of days) told the police he had been kidnapped by Jews. The police went to a hostel where returning Holocaust survivors were staying, and massacred 37 of them.
Sometimes the phrase "blood libel" is used to refer to similar allegations against primarily non-Jewish groups; for example, many nationalities have been accused of kidnapping children to harvest their organs and sell them to rich patients in the developed world.
Although the details have changed over the last millenium, the blood libel retains core elements of sadistic fantasy, psychological projection, and crass opportunism.

(FINANCE) issue of stock by a firm that already has stock in circulation.
Follow-on offerings account for a little over 83% of new finance capital raised on the NYSE. The other 17% was initial public offering (IPO).
Between 1 January and 31 August 2010, 46 companies had made an initial public offering on the NYSE; another 33 had made a follow-on offering. But while the IPO's accounted for $9.5 billion, the FOO's accounted for almost $55 billion.

(LOGIC) a logical fallacy in which a person defends against an allegation by accusing an adversary of doing the same thing. It's a classic douchebag move because it implies that the speaker has a RIGHT to be a douchebag, by virtue of the fact that someone ELSE is being a douchebag.
From Latin, for "you, too."
WHY IT'S BAD
Suppose A is accused of terrorism. He reacts by accusing B, his enemy, of terrorism. Now, it's possible (but unlikely) that A actually chose this argument knowing he was totally innocent. More likely he wants to claim that his terrorism is PROVOKED. In effect, he's saying, "I have to do this, or I'm entitled to do this, because B did it first."
First, as logic it's a red herring. But what makes it douchebaggery rather than just another wartime propaganda tactic, is that it's MORALLY irrelevant as well as LOGICALLY irrelevant. The victims of terrorism almost never have any material control over either perpetrator ever.
ANNA: Abu Yahya, I don't know if your definition of "tu quoque fallacy" belongs in the Urban Dictionary. This isn't Wikipedia, you know.
ABU YAHYA: The reason I did is that I see all the time people using the rationale that, because somebody else did something bad to me, therefore I get to do something similar to anybody. It's sort of like sloppy revenge.
ANNA: Like men punishing random women because their girlfriends allegedly did something shitty to them?
ABU YAHYA: Actually, that's a perfect example of a tu quoque!

In the social sciences, refers to the effectiveness with which a social benefit reaches its intended beneficiaries. When most of the cost of a particular social good is absorbed by intermediaries, such as scalpers and profiteers, distributional efficiency is low.
The state-owned auditorium hands out a fixed number of free tickets to students to promote the arts, but nearly all of them sell the tickets to scalpers for the money. It's very poor distributional efficiency.

(FINANCE) a limited liability partnership (LLP), originally limited to 99 partners, and organized to trade securities under specialized guidelines. The first hedge funds were organized to be a counterparty to the riskiest forms of derivative transactions: writing exotic options or swaps in which the buyer transferred most risks (and potential gains) to the hedge fund, but then offsetting the risk with different derivatives.
The first hedge funds benefited (or thought they benefited) from the Black-Scholes formula used to calculate the value of options; supposedly a hedge fund manager could design an immensely complex portfolio consisting mainly of explosively volatile instruments , whose pieces were supposed to absorb each other's risk.
Hedge funds mainly avoided the consequences of the financial meltdown they helped create, racking up gains through the '00's that far exceeded the rest of the stock market.
The hedge fund used to play a major role in absorbing and structuring the risks associated with hedging risks associated with large portfolios, but they now are sophisticated gambling enterprises.
Hedge funds supply market liquidity for the most exotic of instruments.
