Has anyone empirically tracked aggregate markup over time?

Just checked out of Uni? What did you study, philosophy economics?
Play the game man, focus your brain power on stocks instead.

You are too smart for this forum.

Nope, any hint of philosophical or economic flavor in my explanations are from self-acquired interests. You most certainly do not have to be a genius to apply the occasional novel insight; I am far from it. You just have to think beyond the limitations of single-discipline study. You need enough mental models from different worlds of discourse on hand to synthesize them into appropriate tools for thought and action, or else you will be like the proverbial man with a hammer who treats every problem as though it was a nail. As Charlie Munger remarked in a speech later recounted in Poor Charlie's Almanack...

Since your academic structure, by and large, doesn't encourage minds jumping jurisdictional boundaries, you're at a disadvantage because, in that one sense, even though academia's very useful to you, you've been mistaught. My solution for you is one that I got at a very early age from the nursery: the story of the Little Red Hen. The punch line, of course, is, "'Then I'll do it myself,' said the Little Red Hen." "'Then I'll do it myself,' said the Little Red Hen," So if your professors won't give you an appropriate multidisciplinary approach if each wants to overuse his own models and underuse the important models in other disciplines-you can correct that folly yourself. Just because he's a horse's patoot, you don't have to be one, too. You can reach out and grasp the model that better solves the overall problem. All you have to do is know it and develop the right mental habits.
