PDF Ebook The Basic Analytics of Access to Financial Services
Access to financial services, or rather the lack thereof, is often indiscriminately decried as problem in many developing countries. This paper argues that the —problem of access“ should rather be analyzed by identifying different demand and supply constraints. We use the concept of an access possibilities frontier, drawn for a given set of state variables, to distinguish between cases where a financial system settles below the constrained optimum, cases where this constrained optimum is too low, and–in credit services–cases where the observed outcome is excessively high. We distinguish between payment and savings services and fixed intermediation costs, on the one hand, and lending services and different sources of credit risk, on the other hand. We include both supply and demand side frictions that can lead to lower access. The analysis helps identify bankable and banked population, the binding constraint to close the gap between the two, and policies to prudently expand the bankable population. This new conceptual framework can inform the debate on adequate policies to expand access to financial services and can serve as basis for an informed measurement of access.
Access to financial services or outreach of the financial system has become a major concern for many policymakers in developing countries. While the use of financial services measured as having deposit accounts with banks–reaches over 90% in most high-income countries, in many low- and even middle-income countries the use of formal financial services is still restricted to a small number of firms and households (Peachey and Roe, 2004; Beck, Demirguc-Kunt and Martinez Peria, 2005). Moreover, the intense financial sector reforms undertaken by many emerging economies over the past decade–doing away with interest rate controls and directed credit, liberalizing entry and privatizing state-owned banks–have not led to the type of broadening of access to financial services that was initially expected, particularly for lower-income households and small and medium-size enterprises (SMEs).
Broad access to financial services is related to the economic and social development agenda for at least two reasons. First, a large theoretical and empirical literature has shown the importance of a well developed financial system for economic development and poverty alleviation (Beck, Levine and Loayza, 2000; Beck, Demirguc-Kunt and Levine, 2004; Honohan, 2004a). To be sure, while a causal link running from financial depth to growth has been rather convincingly established by empirical research, the search for causality between the breadth of access and growth is still on. However, as noted by De la Torre and Schmukler (2006a), the discussion of the plausible channels through which financial depth could cause economic growth often resorts to access-related stories. Prominent in this regard is the Schumpeterian view that finance leads to growth because it fuels —creative destruction“ by allocating resources to efficient newcomers. That is, through broader access to external funds, talented newcomers are empowered and freed from the disadvantages that would otherwise arise from their lack of inherited wealth and absence of connections to the network of well-off incumbents (Rajan and Zingales, 2003). Second, access to financial services can be seen as a public good that is essential to enable participation in the benefits of a modern, market-based economy, in an analogous way as is the access to safe water, basic health services, and primary education (Peachey and Roe, 2004). A low level of observed use of financial services, however, has to be carefully distinguished from a problem of access. In a purely theoretical–and rather uninteresting–world characterized by the absence of transaction costs, uncertainty, and asymmetric information there is no —problem“ of access. Decisions to accumulate savings, take out loans, and make payments would be equally open to all and the implementation costless. Banks would not be needed to mobilize savings, facilitate payments, and allocate loans, as savers would assign their savings directly to borrowers based on perfect knowledge of investment possibilities. Hedging or insurance products would not be required given the absence of uncertainty. Access to external finance would be frictionless, limited only by the inter-temporal wealth constraint of the borrower, which would be known equally well and with certainty by both the lender (saver) and the borrower (investor). Investment decisions would be independent of financing and consumption decisions. The choice between borrowing and lending (saving) would be determined purely by inter-temporal preferences and investment opportunities, and changes in borrowing and lending would reflect changes in demand and investment opportunities rather than changes in the possibility of access. In this ideal world, the lack of use of finance by some agents would certainly not be a —problem“ in the commonly used sense of the word. Agents that do not borrow for consumption would be those that do not need to smooth their consumption over time subject to their life-time wealth. And projects that do not borrow for investment would be those that do not meet the condition of a positive real net present value.
Problems of access do arise in some well-defined sense, however, in the real world and are essentially linked to such crucial real-world facts as transaction costs, uncertainty about project outcomes, and information asymmetries. These introduce frictions that can limit access to financial services and that can make it difficult to de-couple investment from financing decisions in most cases. In a world with frictions, investment decisions may reflect credit supply constraints, and not just preferences and business opportunities. It is precisely these frictions which give rise to organized financial markets, financial institutions, and broader contractual entities.1 However, the efficiency with which financial markets and institutions overcome these frictions depends on the macroeconomic environment, market structure, and overall contractual and informational environment. Across countries and over time, we can observe a large variation in the efficiency with which financial markets and institutions are able to overcome market frictions and provide financial services.
