Kheldon writes with an article at MMO Gamer which explores how well real money transactions work in online games, using EVE Online as a test case. Quoting: "... My next problem came from trying to sell the [Game Time cards] through the 'Time Code Bazaar' on the forums. While I quickly found buyers, none of them actually went through with the deal. This is the inherent problem with developer sanctioned RMT. Unless true, unfettered, player-to-player transactions are allowed without developer 'regulation,' the market will inevitably be operating inefficiently. Consider gold-farmers for a moment. Setting aside the moral or legal aspects of the trade, and considering from a purely economic standpoint, gold-farmers are the RMT equivalent of large corporations. They operate on the concept of 'economies-of-scale,' which basically means that up to a certain point, the larger a company is, the cheaper they can produce that product. Of course, companies that can produce a product more cheaply can undercut the competition while maintaining the same profit margin; meaning they'll make more sales, giving them more overall profit, and supporting the corporate growth, which furthers the economy of scale. This is the market at its most pure."
