Economics never labels anything any more. Well, more accurately, it does; only now it hardly ever uses labels formed from people’s names.
In part, this is due to the smorgasbord approach to ideas taken by economics. Like many other academic disciplines, economics ruthlessly mixes and matches, customizes and adapts, rips and mashes the most penetrating insights, the most appropriate models from all different sources, applying them to whichever economic problem is currently being addressed. In those circumstances the message gets through to the practitioner economist that it is more useful to know an idea itself, and how to apply and modify it, than to peer into its provenance or to understand how the originator of that idea thought about three or five other substantively different problems.
