The analysis of fiction or fictional worlds from an economic point of view is an interesting "hobby" of some economists, from the Economics of Harry Potter, World of Warcraft to CSI: Crime Scene Investigation. There appears to be also a stream of research dealing with operas, and in particular Wagner's, which are full of intrigues, hard decisions and conflicting beliefs.
Ilias Chrissochoidis and Steffen Huck look at Lohengrin. The story is about whom to believe, commitment, signaling, normal form games, Bayesian updating, and asymmetric information. I need to listen again to Lohengrin, which I have not touched in decades. Maybe I will hear it with a new ear now that I can recognize all the Economics in it. This paper is totally useless for policy, yet fascinating.
