We estimate the model using a small-scale program in Kenya that creates new opportunities for firm managers to interact. Aggregate gains from the program depend on the relative importance of meeting a high-knowledge firm versus learning within that meeting. We show how moments from the intervention identify these parameters, demonstrating how easily estimated moments beyond the average treatment effect inform at-scale gains. We provide sufficient conditions extending the identification procedure to a broader class of experiments and aggregate diffusion models.<\/jats:p>","DOI":"10.1162\/rest.a.1862","type":"journal-article","created":{"date-parts":[[2026,9,17]],"date-time":"2026-09-17T22:44:52Z","timestamp":1789685092000},"page":"1-46","update-policy":"https:\/\/doi.org\/10.1162\/mitpressjournals.corrections.policy","source":"Crossref","is-referenced-by-count":0,"title":["From Micro to Macro in an Equilibrium Diffusion Model"],"prefix":"10.1162","author":[{"given":"Wyatt","family":"Brooks","sequence":"first","affiliation":[{"name":"Arizona State University"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kevin","family":"Donovan","sequence":"additional","affiliation":[{"name":"Yale University and NBER"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Terence R.","family":"Johnson","sequence":"additional","affiliation":[{"name":"University of Virginia"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"281","published-online":{"date-parts":[[2026,9,8]]},"container-title":["Review of Economics and Statistics"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/direct.mit.edu\/rest\/article-pdf\/doi\/10.1162\/REST.a.1862\/2626396\/rest.a.1862.pdf","content-type":"application\/pdf","content-version":"vor","intended-application":"syndication"},{"URL":"https:\/\/direct.mit.edu\/rest\/article-pdf\/doi\/10.1162\/REST.a.1862\/2626396\/rest.a.1862.pdf","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,9,17]],"date-time":"2026-09-17T22:44:53Z","timestamp":1789685093000},"score":1,"resource":{"primary":{"URL":"https:\/\/direct.mit.edu\/rest\/article\/doi\/10.1162\/REST.a.1862\/138888\/From-Micro-to-Macro-in-an-Equilibrium-Diffusion"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2026,9,8]]},"references-count":0,"URL":"https:\/\/doi.org\/10.1162\/rest.a.1862","relation":{},"ISSN":["0034-6535","1530-9142"],"issn-type":[{"value":"0034-6535","type":"print"},{"value":"1530-9142","type":"electronic"}],"subject":[],"published":{"date-parts":[[2026,9,8]]}}}
