Learning About Real-World Economies Through Game Economies

Reuters has a report about research being done on the in-game economies of MMOs like EverQuest II and World of Warcraft to better understand much larger economic situations in the real world. The games are used as case studies where researchers can do controlled experiments that they couldn't necessarily attempt if real money or goods were involved. "After studying 314 million transactions within the fantasy world of Norrath in EverQuest II, including trading in-game goods like armor, shields, leather, herbs and food, the researchers were able to calculate the GDP of one of the game servers (the back-end computer that hosts thousands of players in one world). As more people opened accounts and flocked to Norrath, spending money on new items, researchers saw inflation spike more than 50 percent in five months. 'We have seen that kind of volatility during times of war and in developing nations in the real world,' said [Dmitri Williams, assistant professor at the USC Annenberg School for Communication]. 'Our own economy has turned out to be less stable than we'd all assumed.'"

These experiments are not as useful nor controlled as you may think. Let me break down into some experiment design principles here:

#1 You can only generalize to the population studied

--Thus your demographics will be that of a more computer savvy user, with leisure time. This is NOT a representative sample of a normal population. When using regression methods you will get a homogenous result only from 'game performers'. These experiments are not valid unless you can prove that there is no purposeful difference between this population and the general population.

--It still can provide interesting insights, but any quantified data must be taken with a grain of salt

--The population may have one net effect, but perhaps a different type of agent/actor would have an OPPOSITE or equalizing effect (games are an artificial setting)

#2 Process defined by agency

--Here the markets are designed by an all-seeing game developer. I don't know about you, but many MMO's I have participated in had lackluster markets due to poor UI or the mere fact that it is a new market.

--Product innovations are limited or non existent, and users cannot refine markets based on their experiences. These days the most interesting economic studies are looking at PROCESS which is understood much less than outcome. Neo-classical economic theory does a great job at explaining outcome, but is horrid at process. That is why many market failures are not forecasted, but instead studied post-mortem.
