Relativistic trading: The speed of light isn't fast enough for some market transactions

The profit made on a stock share bought and sold a moment later might only be a penny or so, but if multiplied by millions of shares over the course of a day the money earned can be big.

Physicsts reveal how to cope with 'frustration'

For most people, frustration is a condition to be avoided. But for scientists studying certain "frustrated" ensembles of interacting components -that is, those which cannot settle into a state that minimizes each interaction-

 it may be the key to understanding a host of puzzling phenomena that affect systems from neural networks and social structures to protein folding and magnetism.

Recurrence Analysis of Stock and Commodity indices

In the contemporary global scenario, the working of the complex and multidimensional factors on the time behaviour of financial series necessitates an investigation of the underlying characteristic features of the same. In addition to the state of the art econometric approaches, analysis in terms of state space dynamics considering the financial time series as deterministic chaos has emerged to be of utmost importance. Understanding the dynamics of a financial series, as a stock market index or a commodity market index is still however, a complex task having its specific requirements.  Market behaviour, in case of both commodity and securities is ultimately reflected by the average trading price movement . Thus the time series representing the indices in the respective markets is a key to understanding the economic similarities/dissimilarities in the two markets.  Our purpose was to analyse the time series representing the indices of commodity and stock markets .

Paul Krugman: Good and Boring ("Right now, Canada is a very important role model")

First, some background. Over the past decade the United States and Canada faced the same global environment. Both were confronted with the same flood of cheap goods and cheap money from Asia. Economists in both countries cheerfully declared that the era of severe recessions was over.
But when things fell apart, the consequences were very different here and there.

In the United States, mortgage defaults soared, some major financial institutions collapsed, and others survived only thanks to huge government bailouts. In Canada, none of that happened. What did the Canadians do differently ?
