Starbucks Index

I guess most people would have known about the Big-Mac index. If you are not too sure, its the comparison of Big-Mac prices around the world and those prices are used to calculate the Purchasing Power Parity. Purchasing power parity like the currenry exchange rate. eg. How much is one USD worth in Japan.

You can take a look a it from this site : http://www.oanda.com/products/bigmac/bigmac.shtml
or the Economist site if you have an online subscription.

So here's my story. One day, I was drinking coffee at, you guessed it, Starbucks !!! I suddenly thought of doing a PPP comparison using the Mocha latte that I was drinking. A Starbucks Index. So I quickly jotted down the prices of coffee from the menu. And I asked my friends from around to world to check out the prices of their Starbucks coffee (most of them have not gotten back to me yet).

Little did I know, that the Economist had actually come up with a Starbucks index two year ago.
Here is how it looks like :

Well, this isn't gonna stop me from doing my own up-to-date version of a Starbucks index. Hang it there, hopefully I'll get most of the data soon. If you want to help out, feel free to do so :)
