Re:Fiat money causes inflation in WoW? (Score 5, Informative)

There's not a real economy in WoW, per say. You get most of your money from quests and kills, which is pretty well-regulated (in the sense that lower level mobs and quests give lower amounts of money, and there's a limit to what you can kill and loot), and you spend most of it in NPC shops. The only semblance of an economy is the auction house and trade channels.

The fact that most of your money disappears into NPC shops with set prices keeps inflation from happening.
