This week, I’d like to discuss two very different topics: state firework policies and university parking. Although the topics themselves seem to have nothing to do with one another, I think that the price theoretic aspects of these topics have something very important in common. Allow me to set the stage. Perhaps it is different now, but when I lived in Michigan, there was a combination of two laws that really confused me. On the one hand, it was legal to buy and sell fireworks.
