Data Sets

I identify the exact building boundaries of 3,000+ public corporations’ headquarters as of their 2019 10-K in my job market paper. For the sake of transparency and as a public good, I developed a visual guide to showcase where these buildings are located and what I mean when I say “within a building.” Here’s an interactive map: Buildings from “Corporate Shadow Lobbying” (Nagaraj 2026). You can click on any point to zoom into the building, or filter for financial factors (like deciles of sales or market cap), and search for firm names, cities, or states to explore the data.
