Demographics and Technology Diffusion: Evidence from Mobile Payments
Working Paper 34885
DOI 10.3386/w34885
Issue Date
We show that the age composition of the population can shape the speed at which businesses adopt new technologies, using evidence from mobile payments in India. Consumers' propensity to use new payment technologies declines with age, creating stronger incentives for businesses serving younger customers to accept these technologies. We document this pattern in the rollout of a mobile payment option by a major fintech company. A model where consumer attitudes toward technology vary by age implies that business adoption is inefficiently low, with the young bearing disproportionate welfare losses from network externalities. Jointly subsidizing transaction and adoption costs restores efficiency.
