Finance

best paper on credit cards f: https://www.complexsystemspodcast.com/episodes/credit-card-rewards-interchange/, How dramatic is this? Allow me to reproduce a graph from the paper "Regulating consumer financial products: Evidence from credit cards." This paper is something of the Rosetta Stone for credit card issuances a field both in that as a single source for understanding a huge range of human endeavor. And that it stands in for a very large literature that nobody else reaches for to be the first citation when the Rosetta stone already exists. If you see an unlabeled graph on Twitter about credit cards, it is probably lifted from this paper.
