Tracking the Credibility Revolution across Fields

How far has the credibility revolution spread beyond applied microeconomics?I update Currie, Kleven, and Zwiers (2020b) using approximately 44,000 papers-31,500 NBER working papers and 12,300 articles from eleven top economics and finance journals (2011-2024)measuring mentions of empirical methods through keyword matching.Three findings emerge.First, finance and macro/other fields differ substantially from applied micro in their mention of credibility revolution methods: as of 2024, 63 percent of applied micro papers mention experimental or quasi-experimental methods, compared to 47 percent in finance and 39 percent in macro/other.The current levels in finance and macro/other are comparable to where applied micro was in 2008-2010, though the long-run trajectories may differ.Second, growth outside applied micro is driven overwhelmingly by difference-in-differences; including DiD raises the share of finance papers mentioning any experimental or quasi-experimental method by roughly 55 percent versus 30 percent for applied micro.Other quasi-experimental methods-instrumental variables, regression discontinuity, experiments-have seen far less growth.Third, I document a striking gap between the methods studied in the Journal of Econometrics-where nonparametric estimation and asymptotic theory dominate-and those used by applied researchers, where DiD and identification strategies dominate.
