Game theory is most often described as a branch of applied mathematics and economics that studies situations where players choose different actions in an attempt to maximize their returns. The essential feature, however, is that it provides a formal modelling approach to social situations in which decision makers interact with other minds. Game theory extends the simpler optimization approach developed in neoclassical economics.

二手车市场是一个很经典的例子：
论文讨论二手汽车的交易。汽车是典型的“经验商品”，用得越久了解越深。因此，二手车的卖主对自己汽车的质量非常了解，而二手车的买主对汽车的质量并不清楚，二手车质量是卖主的私有信息。私有信息的存在，是信息不对称的根源。
