What Explains the Adoption of Digital Payment Methods Among Individuals and Firms in India, and How Have Public Policy Interventions Streamlined and Shaped the Structure of this Transition?

This research paper looks at how households and organizations in India use digital payment methods. It focuses on the Unified Payments Interface (UPI) and explores the government's role in promoting its use. The paper gathers data primarily through a survey. The findings show that the adoption of digital payments depends on the context, and payment patterns are usually non-linear. The trends in the choice process varied by income bracket, age group, occupational category, technology availability, and financial awareness. Transaction size was an additional factor affecting payment choice, particularly among people in higher income brackets. Additional research is needed to verify these findings at the national scale. By applying economic theory, the study identifies UPI adoption as generating a positive consumption externality, which leads to under-adoption. Hence, social welfare loss is due to the absence of intervention. Government actions, like the recent ₹1,500 crore incentive scheme, have been shown to increase digital adoption by reducing costs for businesses and households. However, this rise in digitalization may cause short-term issues due to more formalization and higher tax visibility, especially in informal sectors. Still, it has the potential to act as a long-term boost by improving financial intermediation and transaction efficiency. These findings are important for households, businesses, individual consumers, financial institutions, and policymakers who want to understand how digital payment systems affect behavior, welfare, and inclusion in growing economies.
