三、主要内容：   We propose a population game to analyze drivers’ driving behavior. Each driver interacts with myriad of other drivers in a strategic substitute fashion, namely other drivers’ reckless behavior encourages me driving more carefully. We establish a set of reasonable assumptions, under which this game admits a unique Nash Equilibrium. This allows us to analyze the question that Peltzman(1975) raised: If the driving environment improves, drivers response by driving more incautiously. Can this reaction leads to more auto accidents? To this end, we derive a sufficient condition that rules out this possibility. We then justify this sufficient condition using an empirical regularity we discover from data regarding mutual accidents between different groups of drivers. Through out the analysis, we provide a definition of potential games for continuum of players, where the interaction term depends also on their types. Also the comparative statics result we produced, can be applied to a range of games
with strategic substitutes.                                                    .
