The WoW Economist has an interesting
post about inflation in Northrend. In it they asked a question about whether the mechanisms in Wrath will be able to safeguard the buying power of that gold. They talked about the issue in terms of regulating the amount of currency in the game, which is essentially monetary policy. This is only half of the picture.
First off, I think it is important to note that while economists that deal with monetary policy have the twin tools of interest rate and money supply manipulation, those aren’t the only economists that deal with macroeconomic policy.
Blizzard’s control of the money supply in WoW has to do with droprates and spawnrates. It would be inaccurate to say that there is an unlimited amount of gold in the game, because you can only skin or mine or kill so fast. Blizzard knows on average the value in gold of one person logging in for one hour. Let’s say that value is 50g. They can reduce that amount or increase it by changing spawnrates and droprates.
Our Blizzard Overlords control fiscal policy as well in the WoW economy, which is the other half of the economic toolkit. In the real world this would be collecting taxes and spending money. It is here that I believe that gold sinks can enter the analysis.
Large gold sinks act as a luxury tax. The ridiculous 20,000g mount is a great example of this. It is a status item that would be really tough to justify as an expense, but it will be popular for reasons that fascinate me.
The smaller gold sinks act as a regressive income tax. Everyone pays the same rate for repairs, training, mail service and flightpoints.
These gold sinks are used to reduce aggregate demand, which is the fiscal policy tool used to maintain price levels. People have less gold than they would otherwise, which keeps prices ideally from rising at all, but realistically it will keep them from rising as much.
In the real world some people benefit from inflation. If I owe you $10,000 this year, and next year the purchasing power of $10k is half of what it is this year, in effect my debt is reduced by half. But there is no debt in wow. So there are no real winners when our currency is inflated. But some people lose a lot less than others.
The big losers are the casual players who vendor a lot of white and green drops that they get while questing. These players will have far less purchasing power in wrath than they did in BC.
The smaller losers are people that read blogs like this one. If you have large reserves of gold you should be cringing a little bit, because your purchasing power is being reduced as well, but at least you have the power to fight it. You need to invest in mats that will only increase in relative value rather than keeping vast sums of gold.
The trick is that who knows what investments are good and what investments are bad. What we do know for sure though is that the value of gold will continue to decrease.
