Arbitrage

In economics and finance, arbitrage (/ˈɑrbɨtrɑːʒ/) is the practice of taking advantage of a price difference between two or more markets: striking a combination of matching deals that capitalize upon the imbalance, the profit being the difference between the market prices. When used by academics, an arbitrage is a transaction that involves no negative cash flow at any probabilistic or temporal state and a positive cash flow in at least one state; in simple terms, it is the possibility of a risk-free profit after transaction costs. For instance, an arbitrage is present when there is the opportunity to instantaneously buy low and sell high.

In principle and in academic use, an arbitrage is risk-free; in common use, as in statistical arbitrage, it may refer to expected profit, though losses may occur, and in practice, there are always risks in arbitrage, some minor (such as fluctuation of prices decreasing profit margins), some major (such as devaluation of a currency or derivative). In academic use, an arbitrage involves taking advantage of differences in price of a single asset or identical cash-flows; in common use, it is also used to refer to differences between similar assets (relative value or convergence trades), as in merger arbitrage.

People who engage in arbitrage are called arbitrageurs (/ˌɑrbɨtrɑːˈʒɜr/)—such as a bank or brokerage firm. The term is mainly applied to trading in financial instruments, such as bonds, stocks, derivatives, commodities and currencies.

Baconian method

The Baconian method is the investigative method developed by Sir Francis Bacon . The method was put forward in Bacon's book Novum Organum (1620), or 'New Method', and was supposed to replace the methods put forward in Aristotle 's Organon . This method was influential upon the development of scientific method in modern science ; but also more generally in the early modern rejection of medieval Aristotelianism . Bacon's method is an example of the application of inductive reasoning . By reasoning using "induction", Bacon meant the ability to generalize a finding stepwise, based on accumulating data. He advised proceeding by this method, or in other words, by building a case from the ground up. He wrote in the Novum Organum that: "Our only hope, then is in genuine Induction... There is the same degree of licentiousness and error in forming Axioms, as in abstracting Notions: and that in the first principles, which depend in common induction. Stil...

To PC or NPC: That is the question

When it's time to gear up and get LARPing (live action role playing), you have a decision to make. Do you want to play as a PC (player character) or NPC (non-player character)? For most LARPers, there are several factors involved in making this decision. A PC generally gets to make his or her own choices and become a hero (or villain) on an adventure. An NPC is usually tied to plot and limited in such choices, although there are sometimes phenomenal combat and role play opportunities available to NPCs as well.

Fundamental attribution error

In social psychology, the fundamental attribution error (also known as correspondence bias or attribution effect) is people's tendency to place an undue emphasis on internal characteristics to explain someone else's behavior in a given situation, rather than thinking about external situational. It does not explain interpretations of one's own behavior—where situational factors are more easily recognized and can thus be taken into consideration. The flip side of this error is the actor–observer bias, in which people tend to overemphasize the role of a situation in their behaviors and underemphasize the role of their own personalities. As a simple example, consider a situation where Alice, a driver, is about to pass through an intersection. Her light turns green, and she begins to accelerate when another car drives through the red light and crosses in front of her. The fundamental attribution error may lead her to think that the driver of the other car was an unskilled or rec...
