In this paper, we develop methods of the determination of the rank of random matrix. Using the matrix perturbation theory to construct or find a suitable bases of the kernel (null space) of the matrix and to determine the limiting distribution of the estimator of the smallest singular values. We...

We analyze the optimal regulation of a MFI that has private information on the intrinsic quality of its loan portfolio (adverse selection) and where the MFI’s choice of effort to improve this quality cannot be observed by the regulator (moral hazard). In designing optimal contracts the...

The objective of the study was to enhance our knowledge on institutional bottlenecks for financial development, financial inclusion, and microfinance, using Mauritania as a case study. We used a mixed-methods' methodology that combines analysis of secondary data and an expert interview. First, a...

In this paper, we propose methods of the determination of the rank of matrix. We consider a rank test for an unobserved matrix for which an estimate exists having normal asymptotic distribution of order N1/2 where N is the sample size. The test statistic is based on the smallest estimated...

Purpose Microfinance impact evaluation studies help in discovering client needs which are diverse, special and different from the needs of the conventional bankable clients. Thus, such area of market research is becoming essential for microfinance institutions for designing better client-centred...

In this paper, we employ the Geweke (1982) decomposition method to examine the Granger causality between finance and growth in West Africa. Our sample contains twelve ECOWAS member countries (Economic Community of West African States) and we distinguish two subsamples: seven WAEMU countries...
