I was excited by the title of Robert Shiller’s new book Narrative Economics: How Stories Go Viral and Drive Major Economic Events (2019), but disappointed to find that he defines “narrative” much more widely than the stories I'm looking for, and was hoping to find. Overall, though, I think his meaning is close to my interest in myths: stories spread by word-of-mouth that shape how society imagines itself.
