The relationship between financial inclusion, digital transactions, and overall economic development has been
widely studied across different regions and time periods. Early work by King and Levine (1993) demonstrated
that financial development supports long-term economic growth by enhancing capital formation, improving
credit allocation, and fostering productive investment. Later research by Beck et al. (2007) further showed that
well-functioning financial systems can reduce income inequality by allowing low-income groups to access
affordable financial services.
In the Indian context, Chattopadhyay (2011) highlighted persistent gaps in access to formal finance, particularly
in rural and low-income districts. The study emphasized the need for institutional reforms and targeted outreach
programs to bridge these disparities. Similarly, Sarma and Pais (2011) introduced composite indicators of
financial inclusion and argued that inclusion levels vary significantly across states due to differences in
infrastructure, literacy, and institutional strength.
The literature also identifies digital finance as a major catalyst for modernizing financial systems. Gomber et al.
(2018) noted that fintech innovations—particularly mobile applications, digital wallets, and automated
transaction systems—have redefined the delivery of financial services by offering faster, more efficient, and
more accessible options. Ozili (2018) added that digital finance can strengthen financial stability by increasing
transparency and broadening the customer base of formal financial institutions.
International evidence shows that digital finance can reinforce financial inclusion patterns. Bongomin et al.
(2017), studying sub-Saharan Africa, found that mobile money systems significantly expanded financial access
among unbanked populations by overcoming traditional barriers such as distance, cost, and documentation
requirements. Zins and Weill (2016) also reported that demographic factors, education levels, and income
strongly influence financial inclusion outcomes across African economies.
Within India, digital payments have drawn increasing scholarly attention. Ghosh (2016) observed that mobile
technology adoption has contributed not only to improved communication networks but also to higher
productivity and regional economic growth. Arora and Rathore (2021) studied the impact of digital payments on
monetary transmission and found that digital channels improve the speed and reach of policy measures by
reducing frictions in payment processes.
Recent studies emphasize the role of UPI in transforming India’s payment landscape. Raghavan (2018) described
UPI as a foundational innovation that integrates banks, apps, and merchants into a unified real-time payment
system. Mohan (2023) further analyzed UPI’s growth trajectory and concluded that its success stems from low
transaction costs, interoperability, and strong institutional support from NPCI and the RBI.
Research on financial literacy and behavioural dimensions has also gained importance. Kumar and Prakash
(2021) argued that financial literacy plays a crucial role in enabling individuals to confidently use digital banking
services, which in turn expands overall financial inclusion. OECD (2020) similarly stressed that digital
preparedness and skills are essential to narrowing access inequalities in fast-digitizing economies.
Empirical evidence also links digital payments with macroeconomic outcomes. Studies like Park and Mercado
(2018) and Allen et al. (2016) found that broader access to financial services can enhance economic activity,
increase savings and credit circulation, and support investment capacities. IMF (2021) highlighted that digital
financial services help governments deliver welfare transfers more efficiently, reducing leakages and
administrative costs.
Indian government initiatives such as PMJDY, coupled with rapid digitalization, are seen as complementary
forces. NABARD (2023) reported that formal bank outreach—combined with Aadhaar-enabled services—has
improved credit penetration in rural districts. Meanwhile, the rise of QR-based transactions, AEPS, and app-
based platforms has propelled India to one of the world’s fastest-growing digital payment markets (NPCI, 2024).
Despite extensive scholarship, the combined macroeconomic effect of financial inclusion and digital payments
remains underexplored. Many studies examine these themes separately—focusing either on banking access,
mobile adoption, or fintech growth—but few assess how they jointly influence GDP, inflation, or financial sector
