Financial sector research in Africa – looking forward

11.11.2013Thorsten Beck

It is about two years ago that the AfDB, GIZ and World Bank published the Financing Africa book, a broad analysis of trends in Africa's financial systems, of gaps and challenges, and of different policy options. For researchers focused on Africa's financial systems, the past years have been exciting, with many different forms of innovations being introduced and assessed. But there have also been new challenges for analysts and policy makers alike, as I will lay out in the following. Cooperation between different stakeholders, including practitioners, donors, policy makers and researchers can help move forward the frontier for Africa's financial systems. In the following, I will focus on five areas where more data and more research can support better informed policy making.

Long-term finance

One first area is that of long-term finance, which can be seen as the second (next to lack of financial inclusion) critical dimension of shallow financial markets in Africa. As documented in the Financing Africa publication, there is a bias on banks' balance sheets toward short-term liabilities and, more critically, short-term assets, only few countries have liquid equity and debt markets, and there is a dearth of effective contractual savings institutions, such as insurance companies, pension funds and mutual funds. This dearth of long-term financial intermediation is in contrast to the enormous need for long-term financing across the continent, for purposes of infrastructure, long-term firm financing for investment and housing finance.

The long-term finance agenda is an extensive one, both for researchers and policy makers. First, there is still a dearth of data on long-term financing arrangements, including on corporate bond market structures and costs, insurance markets and private equity funds. Second, identifying positive examples and gauging interventions and policies will be critical, as will be expanding to Africa the small literature on equity funds and their effect on enterprises that exists for U.S. and Europe and (increasingly) for emerging markets. One important constraint mentioned in the context of long-term finance is the lack of risk mitigation tools. Partial credit guarantees can play an important role, but their design and actual impact has not been studied sufficiently yet.

Small enterprise growth

A second important challenge is that of extending the financial inclusion agenda from micro- up to small enterprises, both in terms of supply- and demand-side constraints. The emphasis stems from the realization that job-intensive and transformational growth is more likely to come through formal than informal enterprises. Assessing different lending techniques, delivery channels and organizational structures conducive to small business lending is important, as is assessing the interaction of firms' financing constraints with other constraints, including lack of managerial ability and financial literacy. This research agenda is important for both financial institutions and policy makers. For financial institutions, the rewards can lie in identifying appropriate products for small enterprises and entrepreneurial constraints that might prevent take-up and impact repayment behavior by small enterprises.

For policy makers, the rewards can lie in identifying policies and institutions that are most relevant in alleviating small firms' growth constraints.

Regulatory reform agenda

A third important challenge refers to regulatory reform. While global discussions and reform processes are driven and dominated by the recent Global Financial Crisis and the fragility concerns of economies with developed if not sophisticated financial markets, Africa's fragility concerns are different and its reform capacity lower. Some of the suggested or implemented reforms seem irrelevant for almost all African countries (such as centralizing over-the-counter trades) or might have substantially worse effects in the context of shallow financial markets than in sophisticated markets increasingly dominated by high frequency trading (such as securities trading taxes). Prioritizing regulatory reforms according to risks and opportunity costs for financial deepening and inclusion is therefore critical in the definition of the regulatory reform agenda for African countries. While not necessarily an area for fundamental academic research, financial sector researchers can contribute to this conversation by helping identify regulatory constraints for financial deepening and broadening and potential sources for stability risks, based on past experiences from Africa and other regions.

Cross-border banking

A fourth important challenge is that of cross-border banking and the necessary regulatory framework. Identifying cross-border linkages between countries is critical, and data collections, such as by Claessens and van Horen (2014), represent an important first step. Understanding the channels through which cross-border banking can help deepen financial systems and foster real integration, and the channels through which cross-border banks can threaten financial stability, is critical. In this context, the optimal design of cross-border cooperation between regulators and supervisors to minimize risks from cross-border banking while maximizing its benefits is important (Beck and Wagner, 2013). African supervisors have been addressing the challenge of regulatory cooperation both on the bi-lateral and sub-regional level as well as on the regional level, with the establishment of the Community of African Bank Supervisors. Financial research can support this cooperation and integration process.

The politics of financial sector reform

A final important area is the political economy of financial sector reform. Short-term political interests and election cycles undermine the focus on long-term financial development; interests to maintain the dominant position of elites undermine the incentives of governments to undertake reforms that can open up financial systems and, thus, dilute the dominant position of the elites. On the other hand, the financial sector is critical for an open, competitive, and contestable economy because it provides the necessary resources for new entrants and can thus support economic transformation. Better understanding the political constraints in financial sector reforms and identifying windows of opportunity are therefore important. Focusing on the creation of broader groups with a stake in further financial deepening can help develop a dynamic process of financial sector reforms. An increasing literature has tried to understand the political economy of financial sector reform in developed and emerging markets; extending this literature to Africa can support the optimal design of financial sector reform programs.

Conclusions

Research in these five areas will have to be supported by an array of new data and a variety of methodological approaches. This implies expanding data availability towards non-bank providers, such as equity funds, but also exploiting existing data sources better, including credit registry and central bank data sets. In addition to exploiting more extensive micro-level data sets, a variety of methodological approaches is called for. I would like to point to just two of them. First, randomized experiments involving both households and micro- and small enterprises will shed light on specific technologies and products that can help overcome the barriers to financial inclusion in Africa. One of the challenges to overcome will be to include spill-over effects and thus move beyond partial equilibrium results to aggregate results. Second, further studies evaluating the effect of specific policy interventions can give insights into which policy reforms are most effective in enhancing sustainable financial deepening and positive real sector outcomes.

For research to succeed in obtaining the necessary data, asking relevant questions but also maximizing its impact, a close interaction between researchers and donors, practitioners and policy makers is necessary. This relationship can often be critical for obtaining micro-level data, such as from credit registries or specific financial institutions, or for undertaking experiments or RCTs. However, these links are also critical for disseminating research findings and having an impact on practice and policy in the financial sector.
