Unlike traditional firm production, gig economy workers provide their own physical capital. As a consequence, the low-income households for whom gig economy opportunities are most valuable often borrow to participate. In the context of ride share, difference-in-difference analysis reveals increased vehicle purchases, borrowing, utilization, and employment around entry, but financially constrained individuals cannot participate. To assess the equilibrium importance of financing, I build and estimate a structural model of the gig economy. Access to finance proves critical for the gig economy's growth: without finance, equilibrium quantities would be 40% lower and prices 90% higher, and only higher-income households could participate as drivers.
