Taylor Swift's Eras tour has generated quantifiable economic impacts seen in retail sales, inflation, and bumps for cities that hosted concerts. Small businesses across America are capitalizing by hosting Swift-themed events like a skate night in Ohio and brunches in California. These events attract hundreds of attendees and create ripple effects for other local businesses. Experts say Swift has created her own "micro-economy" and these grassroots celebrations benefit her brand even if she's not present.
