    Published 2019 Hsieh & Moretti paper estimated ~3.7% output gain, not 2%

    Before

    would increase US GDP by approximately 2%, roughly $400 billion annually

    After

    would increase US GDP by approximately 3.7%, roughly $400 billion annually

    Why: Verified already correctly fixed in body content (3.7%, matching the Hsieh & Moretti 2019 AEJ:Macro bibliography citation). FAQ mentions the same research only in vague terms ('reduced American GDP by billions of dollars annually') without repeating the stale 2% figure. Excerpt does not mention this figure. No further action needed.
