New BTOS AI Supplement from Census released today. AI use for any business function varies dramatically across sectors and firm size. In AI intensive use sectors, employment-weighted AI use 60-70% -- compared to 32% economy-wide employment weighted. See www.census.gov/library/work...

The Microstructure of AI Diffusion: Evidence from Firms, Business Functions, and Worker Tasks
Using new Business Trends and Outlook Survey data, we find AI use prevalent in large firms and knowledge-intensive sectors; augments tasks; labor declines rare.

Finally out in AEJ:Macro👉 The Evolution of US Retail Concentration w/@dominicsmith.bsky.social Census data👉*National and local* concentration increased 1982-2012 Trends hold for product and industry markets 🔗https://www.aeaweb.org/articles?id=10.1257/mac.20220249 @aeajournals.bsky.social
Front page of the paper "The Evolution of US Retail Concentration" published in the American Economic Journal: Macroeconomics, January 2025.
The Abstract reads: 
Increasing national concentration has contributed to market power
concerns. Yet local trends are more informative about market power in
retail, where consumers have traditionally shopped at nearby stores.
Using novel product-level census data for all US retailers, we find
that local and national concentration increased in parallel and affect
most markets, products, and industries. The expansion of multimar-
ket firms into new markets explains most of the increase in national
concentration, with consolidation via increases in local market shares
increasing in importance between 1997 and 2007. Increases in local
concentration can explain one-quarter to one-third of the observed
rise in retail gross margins.
