“What drives development” has long been a fundamental question for many scholars and policymakers. One consensus reached is that financial inclusion – access to and use of formal financial services by all members of an economy – is a central tenet of development . It facilitates efficient allocation of productive resources by reducing the volume of money outside the banking sector, i.e. by shrinking the informal sector . Conversely, exclusion from the formal financial system reinforces social inequalities and deepens poverty.
However, the World Bank’s (2017) Global Findex Database indicates that about 1.7 billion adults across the world are still unbanked and therefore they are excluded from the formal financial system (see figure below). Evidence further indicates that almost all the unbanked population lives in developing countries and nearly half of these live in just seven countries: Bangladesh, China, India, Indonesia, Mexico, Nigeria and Pakistan.
But why are developing countries the home for the unbanked? In order to answer this question, we first need to address the cause of market failures leading to exclusion in emerging markets; namely institutional voids.
Globally, 1.7 billion adults lack an account [Source: Global Findex database . Note: Data are not displayed for economies where the share of adults without an account is 5 percent or less.
Institutional theory suggests that institutions shape the conditions that drive socio-economic development and the particular rules that actors follow within a given context . As Scott (1995) points out, institutions are socially constructed and embedded structures that provide the rules and frameworks upon which societies operate. If these institutions are absent or weak, it can create institutional voids that impact economic growth and development [4,5].
Therefore, while every economy should have a range of institutions (e.g. payment processing systems, contract enforcement, etc.) to support financial inclusion, many developing countries fall short. Thus, it is lack of, or weak institutional frameworks, i.e. institutional voids, in developing countries that differentiate them to a great degree from developed countries. The presence of institutional voids is apparent in the inefficiency of the formal financial systems to provide appropriate services, quality of institutions and legal origins . Such institutional voids cause buyers and sellers to experience information asymmetries and uncertainty, thus creating serious operating challenges and higher transaction costs (i.e. the cost of capital) in emerging markets. All these act to constrain financial inclusion, and in effect hamper prosperity and wealth creation.
Digital platforms, which have rapidly grown in number and reach in developing countries, have the potential to generate social and economic value by filling the voids and thus building well-functioning markets. For instance, digital platforms for financial services can enable individuals and businesses to more easily reach and find previously hard-to-locate financial services. They also have the potential to facilitate the accumulation of capital by lowering search and transaction costs, reducing information asymmetries and thus fostering trust between parties .
Despite this recognition, however, the linkage between digital platforms and institutional voids in these contexts remains significantly underexplored. Apart from a few studies (e.g. ) that explored the importance of digital platforms in institutional development and capacity building in developing countries, the focus of the literature on digital platforms in emerging and transitioning economies has been mainly on the general functioning of digital platforms (e.g. business strategy, platform governance and consumer behaviour) . Therefore, we need more research to better understand how digital platforms could help alleviate the negative impact of institutional voids in developing countries, such as in the banking and financial system.
