"A Multiplayer Game Environment Is Actually a Dream Come True for an Economist"

The in-house economist for the company behind Half-Life and Portal explains what video games can teach us.

In October 2011, the Greek economist Yanis Varoufakis received an unusual email. "I'm the president of a videogame company," it began. The message was from the head of Valve Software, the influential video game design firm behind such industry-defining titles as the sci-fi shooter Half-Life and the first-person puzzle adventure Portal.

Varoufakis, who teaches economic theory at the University of Athens and also has a post at the University of Texas at Austin, had spent years working on game theory—the strategic and decision making processes that economists study, not the theory behind computer games. He also examined the complexities of linking multiple distinct economies. During the height of the Euro crisis in Greece, Varoufakis was often seen in the media explaining the meltdown and describing what might happen next in the currency-integrated Eurozone. Now Valve Software chief Gabe Newell was asking him to apply the same insights to the interlinked virtual economies of Valve Software's games.

After meeting Newell and other Valve staffers in Seattle, Varoufakis agreed to become the company's first official in-house economist. From early 2012 through the middle of 2013, he studied Valve's games, occasionally sharing his insights on the company blog in lengthy posts with wonky titles. (Sample: "Arbitrage and Equilibrium in the Team Fortress 2 Economy.") His work for Valve led to more media attention, including articles and interviews in The Washington Post, The Financial Times, and National Public Radio.

In February, Varoufakis spoke with Senior Editor Peter Suderman about what he learned as a video game economist, the failings of his chosen academic profession, and how computer games and virtual online worlds might be the future of macroeconomics.

reason: What does a video game company want with an economist?

Yanis Varoufakis: The moment that video game companies shifted from single-player to multiplayer games, without realizing it, they created a social economy. People interacting through the game have the opportunity not only to kill one another, but also to exchange stuff. Stuff that was valuable-or scarce, as an economist would say-within the virtual world.

In almost no time that sort of economy started creating, within the game, a lot of value, and also distributing it. If you have a kind of community involving millions of people who trade with one another, who engage with one another, and who can even create value through production processes-for instance, designing some shield or some garden and sending it through the store of the community to other players-all of a sudden, these video game companies realized that they have an economy in their hands.

reason: So the interest for economists is that you have a confined space to learn about how people behave within economies. And the interest from gaming companies is that they inadvertently created economies that they needed some expertise on.

Varoufakis: A multiplayer game environment is a dream come true for an economist. Because here you have an economy where you don't need statistics. And elaborate statistics is what you use when you don't know everything, you're not omniscient, and you need to use something in order to gain feeling as to what is happening to prices, what is happening to quantities, what's happening to investments, and so on and so forth. But in a video game world, all the data are there. It's like being God, who has access to everything and to what every member of the social economy is doing.

reason: You have the perfect knowledge that every central banker wishes he or she had.

Varoufakis: Indeed. Every congressman, every senator, every regulator, every banker, every Treasury official. It's equivalent to being omniscient, being able to see and know everything that goes on in the economy. And that's amazing.

reason: You've said that you were not really a gamer before working with Valve. What did you learn about video game worlds? What surprised you?

Varoufakis: The most poignant observation was the speed with which these economies evolve. Within a year, you have an evolutionary process that can replicate what happened out there in the outlying economies, in terms of creating a complex web of exchanges and sound economic systems. And the outlying economy took centuries. I didn't expect to see institutions spontaneously generating within these social economies so fast and so furiously, and therefore creating a growth rate that the real world would love to replicate.

I also learned something else which I'm very grateful for. We economists are very much disposed toward our models, and our models assume that economic choices converge very quickly toward some kind of equilibrium where demand equals supply and where prices tend to their natural level and so on and so forth. Well, that's not how the real world works. We should have known that.

In the video game world it's quite astonishing to watch. Quickly, collective aggregate behavior converges at equilibrium and then disequilibrates itself. Then some other equilibrium comes and then goes away. It's the speed and the irregularity of behavior around some equilibrium and the speed with which new equilibria are being formed.

    Interesting stuff. I've never really thought too much about the research angle of gaming economies before, more focused myself on the social interactions to be found there. It'll be fascinating to see what develops in the coming years as these communities become ever more complex.

    By social interactions, do you mean "Hi stranger. Meet my friend, Tommy the Talking Shotgun. Say Hi, Tommy!"

  • HenryC||

    You are talking first person shooter. In multiplayer games it is more hi neighbor, see that place over there, lets get together and loot it.

    As far as I'm concerned there are three genres of video games: FPS, RPG, and RPS-RPG hybrids with elements of stealth.

    And he needed help moving millions in profits out of Nigeria?

    I don't know about Valve Games, but if he was a President of CCP, he probably would have asked for help moving billions of ISK from Jita. They just keep burning that place. I don't play EVE, but from what I've read, that game has insanely developed economy with full production cycle (mine, manufacture, trade, use, blow up, scavenge scrap) and trade and all-human mega corporations.

    There are a couple of online games that I play, and I am amazed sometimes to see how many of the players understand the idea of gold sinks and faucets. Every time there are sharp movements of prices on the markets, discussions pop up of what is going on and the players seem to intuitively understand the economics. Even for some fairly simple games, the in-game economy is a pretty big part of the experience. (Thank god for hat collectors that will pay outrageous prices for one-of-a-kind hats.)

    If you google something like 'inflation ruining online game' you can find discussions of problems with the economies of any number of online games.

  • Malkavian||

    Massive team based online games are the future. Too bad they feel like full time jobs. On the bright side, they have the potential to showcase human abilities in a way that would be costly to replicate in real world. For example, management experience in a quality, land holding clan in World of Tanks would impress me more than a four year degree in English or Communications. Probably the same for EVE corporate management. It won't substitute for software engineering degree, but then again, if you programmed/develop any mods for the game, depending on the quality/difficulty of the mod, maybe it will.

  • Peter Suderman||

    Neal Stephenon's most recent novel kind of implied that massive online games might actually become your full-time job...

  • Tommy_Grand||

    Yes, aside from the pure crap subplot about terrorists in the RV.

  • Redmanfms||

    It's not fiction, free-to-play economics actually allow people to be dedicated gamers and earn a living using purely in-game economics.

    That's not counting the Twitchers and Utubers and various Machinima partners who make money with advertising and voluntary donations from fans/followers.

    Even back in the day 10-12 years ago I knew some nerds in the Navy who made surprisingly big money building EverCrack characters and selling them online.

    Epic is taking a lesson from Valve and going further with the next Unreal Tournament
    using collaborative development model with players, where traditionally there had been a strict separation between core game and player mods, all of their source code posted on github, and:

    So what’s the catch?

    It will take many months until the game is playable by gamers. This is real development from scratch.

    When the game is playable, it will be free. Not free to play, just free.

    We’ll eventually create a marketplace where developers, modders, artists and gamers can give away, buy and sell mods and content. Earnings from the marketplace will be split between the mod/content developer, and Epic. That’s how we plan to pay for the game.

    There is labor markets (crafting) and financial speculation ( auction House) in the game of World of Warcraft. Maybe he should talk to blizzard. It is the oldest Multiplayer economy going, if not quite as economic based as EVE.

  • trig||

    Crafting in WoW hardly counts as a labor market since you can do it with practically no time invested. I think the "labor" market market in eve actually involves people spending time doing a task in exchange for a wage. Like that big battle that broke out because a financial glitch caused some mercenaries not to receive their money and they left an area unprotected as a result.

    Crafting in WoW hardly counts as a labor market since you can do it with practically no time invested.

    I disagree. To craft objects in any meaningful quantity either requires a lot of time spent gathering materials or paying someone for them, much like real life. Just because the "i clicked the button it's made" part isn't time consuming doesn't mean the process isn't time consuming.

  • anon||

    I thought this was all self-evident with any MMO (Ultima Online, World of Warcraft, etc.) With (relatively) unregulated markets, these game economies rarely, if ever, experience a "recession" or "depression." Kinda thought it was just the perfect example of how free markets would work.

  • Warfario||

    I remember playing Star Wars Galaxies, which had an incredible in game economy. First, you had to mine resources. The resources found on any one planet would change week to week and the different resources would have different qualities. When you produced certain items, the quality of the resources and the quality of the tools you used would determine the quality of the item produced, so you could find low quality and low priced goods or search out the best items if you were willing to pay a bit more. You could then make blueprints that you could load into a 'factory' building along with some resources and it would mass produce the item for you. You could also create 'vendor' NPCs to sell your items. As a master weaponsmith and architect, I had a few economic battles with rivals (strangely it was the architect line where the economic battles were waged, other weaponsmiths were generally very nice and helpful.)

    In addition, some of the professions depended on higher order goods produced by other professions or from within your own profession line. As an architect, for example, a building might require 5 'wall units' and a generator. An entry level architect could produce the higher order goods, but it would require a master architect to put the items together so low level crafters didn't have to produce useless items and destroy them in order to gain experience as happens in a lot of other MMOs.

    On the other hand, some of the best weapons in the game could only be produced with Krayt Dragon scales. This required crafters to buy from the fighting classes to produce. All this created a very interdependent economy.

    At times I would see posts on the forums for crafters where they would try to collude to keep prices high, but with no way to enforce this, these schemes would generally die before too long.

    Finally, there were player owned cities. As a mayor of a city that I wanted to be famous for crafting, and as a libertarian, I decided there would be no sales tax in our city and I would pay for the city maintenance out of my own profits. This worked out great as more crafters moved to the city and set up shop, this also increased my own sales.

    its awesome,,, Start working at home with Google. It’s a great work at home opportunity. Just work for few hours. I earn up to $100 a day. I can’t believe how easy it was once I tried it out www.Fox81.com

    During high school, I played a ton of World of Warcraft. It was there that I first experience the theory of supply and demand in action (at the Auction House). A few years later I wrote an essay for a scholarship about entrepreneurship. I mentioned that MMOs are a great place where video game fun and practical learning intersect. I always suspected that video games are a great way to explore practical learning, and this article certainly supports that. I'm excited to see what the future holds.
