Why do we live in the golden age of economic history? Was there something identifiable that caused the subfield to grow in esteem? Some new technology that changed the costs of research (not that I can see)? Something else?
Mark Koyama should write a Medium essay on this, but in the meantime here are my thoughts:
1. We now know much, much more about the earlier economic histories of China, India, and some other locales. The rise of more and better graduate students from the emerging economies, or for that matter from Europe, has been essential here.
2. Some of the turn toward economic history came with the financial crisis, and the search for longer-term parallels, which meant looking back in history, most of all to the Great Depression.
3. Although the advance of cliometrics started a long time ago, we are now finally at intergenerational margins where economic historians are as quantitatively well-equipped as most parts of the applied micro spectrum.
4. The stranger the time period, the more people will have to look to broader stretches of history for understanding. Yes, this one is an uh-oh.
5. Some applied micro fields have become a little more boring, so that has helped a partial shift of status to economic history. Public data sets have been exhausted, and a lot of economic history data sets are “weird or idiosyncratic” data sets, which now are “in” and I predict will stay “in” for a long while to come because they offer the possibilities of both new discoveries and moats.
6. An academic trend that hasn’t yet been exploited usually ends up exploited, sooner or later, once the right nudge comes along.
5b, 6b. In chess, the top players are opting for the Giuoco Piano once again.
7. Competing economic models are more “allowed” in the subfield — not everything must be neoclassical — which has opened economic historians to more wide-ranging questions. Economic history remains a good place to pursue the questions about economics that initially interested many people as undergraduates.
8. Academic attention is more media-driven these days, and good economic history papers usually have a story of some kind, and perhaps also a historical personage, event, or institution of broader interest.
