The creators of Team Fortress 2 have hired their very own economist to help out with their various crazy hat-based projects.

Writing on his new blog over at Valve's website, newly-minted consultant Yanis Varoufakis discusses how he met with Valve chief Gabe Newell and put a deal together.

"Within hours, an agreement was reached: I would become, in some capacity (that was to be hammered out later), Valve's economist-in-residence," he writes.

"My intention at Valve, beyond performing a great deal of data mining, experimentation, and calibration of services provided to customers on the basis of such empirical findings, is to to go one step beyond; to forge narratives and empirical knowledge that (a) transcend the border separating the ‘real' from the digital economies, and (b) bring together lessons from the political economy of our gamers' economies and from studying Valve's very special (and fascinating) internal management structure."

And hats. Never forget hats.
