Valentine's Day Special - A Mathematical Aphrodisiac

Come Valentine's Day a lot of things happen around you. On one side one can see young men and women doing really crazy things to express their 'love'. While on the other side self-appointed policemen of culture, tradition etc come out with lathis and unleash terror. This is also the season when business heats up, specially for flower shops, greeting card, gift articles and so on. And the ubiquitous media does a good coverage of all these. When all the world is whirling with activity there is one category of people which doesn't seem to do much - the mathematicians. Mathematics is often perceived as a boring subject and mathematicians are often characterized as lost in their own proofs. Sometimes mathematicians can be interestingly romantic as well.

GFCI 8 and a Forgotten Report

The Global Financial Center Index (GFCI) is a composite index that provides relative competitiveness of 75 financial centers across the world. It is a bi-annual report published by Z/Yen group, based out of London, with the support of the City of London Corporation. First published in 2007 the index covered only 46 centers. Slowly it has increased its ambit to 75 centers. 


The GFCI is computed using both quantitative and qualitative factors. The quantitative factors or the instrumental factors, as the report calls, have their base in secondary data sources. Many reports like that of the World Bank, Transparency International etc are used to cull the instrumental inputs. The qualitative inputs are obtained from international financial executives through an ongoing online questionnaire-based interview. The recent report is based on more than 33,000 responses from more than 1,800 professionals. The rating model has undergone substantial qualitative up-gradation.

The recent report has a few surprises. London is rated as the best IFC this year. Well, this is not the surprise I just said.
