Iowa Electronic Markets

From Wikipedia, the free encyclopedia
How it works
Here are examples of contracts that the IEM traded, beginning June 6, 2006, concerning the 2008 US Presidential Election Winner-Takes-All Market. (The contract descriptions came from the IEM site.)
DEM08_WTA
$1 if the Democratic Party nominee receives the majority of popular votes cast for the two major parties in the 2008 U.S. Presidential election, $0 otherwise
REP08_WTA
$1 if the Republican Party nominee receives the majority of popular votes cast for the two major parties in the 2008 U.S. Presidential election, $0 otherwise
On the first trading day in January, 2007, the DEM08_WTA contract sold for 52.2 cents.
At this point, a speculator has a number of options.
1. He can simply buy a number of DEM08_WTA shares and wait for the results of the election. If the Democratic Party nominee receives the majority of popular votes in the 2008 Presidential Election, the speculator would have his contract liquidated and receive $1, for a profit of…

Knowledge market

From Wikipedia, the free encyclopedia

The knowledge economy brings with it the concept of exchanging knowledge-based products and services. However, as discussed by Stewart (1996)[1], knowledge is very different from physical products. For example, it can be in more than one place at one time, selling it does not diminish the supply, buyers only purchase it once, and once sold, it cannot be recalled. Further, knowledge begets more knowledge in a never-ending cycle. Understanding of knowledge markets is beginning to emerge. As would be expected, they are very different in form from traditional markets.
Knowledge markets have been variously described by Stewart (1996)[1], Davenport and Prusak (1998)[2], and Simard (2000) as a mechanism for enabling, supporting, and facilitating the mobilization, sharing, or exchange of information and knowledge among providers and users. This transactional approach assumes that knowledge-based products or services are available for distribution, that some…

Financial market

From Wikipedia, the free encyclopedia
In economics, a financial market is a mechanism that allows people to easily buy and sell (trade) financial securities (such as stocks and bonds), commodities (such as precious metals or agricultural goods), and other fungible items of value at low transaction costs and at prices that reflect the efficient market hypothesis.
Financial markets have evolved significantly over several hundred years and are undergoing constant innovation to improve liquidity.
Both general markets (where many commodities are traded) and specialized markets (where only one commodity is traded) exist. Markets work by placing many interested buyers and sellers in one "place", thus making it easier for them to find each other. An economy which relies primarily on interactions between buyers and sellers to allocate resources is known as a market economy in contrast either to a command economy or to a non-market economy such as a gift economy.
In Finance, Financial mar…

Risks and liabilities

Although instant messaging delivers many benefits, it also carries with it certain risks and liabilities, particularly when used in workplaces. Among these risks and liabilities are:
• Security risks (e.g. IM used to infect computers with spyware, viruses, trojans, worms)
• Compliance risks
• Inappropriate use
• Intellectual property leakage
Crackers (malicious "hacker" or black hat hacker) have consistently used IM networks as vectors for delivering phishing attempts, "poison URL's", and virus-laden file attachments from 2004 to the present, with over 1100 discrete attacks listed by the IM Security Center[7] in 2004-2007. Hackers use two methods of delivering malicious code through IM: delivery of virus, trojan, or spyware within an infected file, and the use of "socially engineered" text with a web address that entices the recipient to click on a URL that connects him or her to a website that then downloads malicious code. Viruses, worms, and trojans…
