Last week I started thinking about goozex.com and what fundamental economic patterns you would see if you had complete access to their trading logs. For those who haven't heard of it, goozex is a trading platform for used game and computer software. Sellers who are looking to unload some goods can go to goozex and get paired up with buyers who are looking for specific game titles.

It may sound like a niche version of eBay, but there are a couple of things that make it interesting. For starters, any transaction between users will always boil down to an exchange of 1 software title for a quantity of goozex points, the trading currency used on the site. The point value of any software title is regulated by goozex, meaning that sellers do not have the ability to set their own prices, and buyers do not have the ability to pay more or less for a given software title.

With such a tight control over the marketplace for specific goods, I'm interested in a couple of things:

1. How quickly do supply and demand react to changes in point value?
2. How quickly does demand increase for a big release? How long does it take to reach a steady level?
3. How long is the trading market for a new title likely to be supply-starved?

Goozex has a good amount of market information available for any given item but there is no historical visibility, so I've set up a database and a django application to track of some of the market dimensions for a range of items. Some are big AAA titles and some are shovelware with small markets. New data points are added every hour or so for newer items, and less frequently for older ones. The list below only shows titles that have been released, but I've dog-eared a couple of titles that will start accumulating data as soon as they are released.

Have any tracking requests, or predictions on the patterns that will emerge in this experiment? Stick them in the comments below.
