No, seriously. Most MMOs require that you pay a listing fee (usually some small percentage of the item's list price) in order to place it up on the market. Do this whenever an item is listed and whenever the item's price is changed and you'll see the rampant undercutting grind to a rapid halt. The markets will stabilize very quickly and people might actually be able to make a decent profit from gathering and crafting.
Just because other MMO's do this it does not make it a good idea. That is fallacious logic.
I have explained time and time again in numerous threads why imposing a listing fee is a bad idea.
