Many teachers know that encouraging interest in economics can be difficult because students often find the "dismal science" abstract and, well, dismal. It’s basically a truism that if economists want to engage the public, they should use interesting and relatable examples. And more often than not, this means mining pop culture for teaching moments from music, TV, and film. In addition to these conventional examples though, I suggest economists begin to look to video games for inspiration.
In the last few years, there has been an explosion of interest in the economics of the video game industry, and especially in the digital economies that emerge within games. Whether we look at social interaction and trade, or money and inflation, it’s obvious that as games become more complex, they increasingly illustrate economic principles. The most common examples come from MMO titles like World of Warcraft and EVE Online, but games incorporate economic ideas in more fundamental ways as well.
I’ve discussed in a different article how games imply economic behavior, and how making decisions within a game highlights the fundamentals of human action. The basic idea is that virtual worlds, like the real world, present us with a series of choices. Games impose digital scarcity, obliging players to weigh the benefits of different courses of action, make tradeoffs, and incur costs.
Good examples are found in the RPG genre, where players face tough choices between different specializations and skill trees. To take one universal example, brute strength often comes at the expense of nuance in magic or persuasion, and alternative skills are not equally useful. Note also that obliging players to make difficult decisions highlights the opportunity cost of choice, not the often misleading money cost. Sure, you might use a lot of XP or in-game currency to buy skills, but gamers who plan carefully are well aware that the true cost of their choices are the skills they forego. In this sense, acquiring virtual skills is not unlike acquiring human capital; in fact, in some cases, they may even be the same thing.
Games also encourage players to think entrepreneurially: to take risks and sacrifice scarce resources in order to profit. Entrepreneurs specialize in a kind of creative problem solving in the marketplace, and gamers do much the same in the virtual sphere.
Choice, cost, and entrepreneurship are just a few of the economic concepts that games illustrate. But there are many more ways—real and metaphorical—to bring gaming into economics, and vice versa. Economics teachers and researchers should keep an eye on the gaming industry, which seems likely to continue to play an important role in pop culture, and therefore also in shaping popular ideology.
