Abstract
Purpose – These last three years, the global reputation of microfinance has been damaged by some major crises, notably in India. The Microfinance Investment Vehicles (MIVs), funded by public money and socially inclined investors, are believed by observers to be part of the causes of the crises (von Stauffenberg & Rozas, 2011). As a consequence, they now have to demonstrate their commitment to the social mission of microfinance. This chapter aims at putting forward the debate on MIVs’ ability to effectively contribute to the social mission of microfinance by analyzing how they integrate social performance in their investment decisions.
Methodology/approach – Analysis of interviews with microfinance fund managers based on a framework of recognized impediments to a socially responsible approach in investing.
Findings – While social performance is recognized by respondents to be an important topic for the industry, fund managers still do not give a strong role to social criteria in investment decisions. The findings of the qualitative analysis in the chapter demonstrate that this is linked to a number of major impediments such as the tendency to believe that microfinance is social per se, the lack of standardization in social performance tools, and also a loose regulation regarding social reporting.
Research limitations/implications – The findings of the study are limited due to the relatively small sample size and the focus on fund managers’ answers only. Future research could investigate the viewpoints of different stakeholders in the investment process, such as the back investors of microfinance funds or the regulatory institutions.
Originality/value – To the best of our knowledge, this is the first attempt to get insights on the impediments to a stronger focus on social performance by MIVs, with the application of a recognized framework from the Socially Responsible Investment (SRI) literature.

Abstract
Purpose
The purpose of this study is to determine whether there exists employee-client matching at the bottom of the pyramid (BOP) and the most favourable employee-client categorization in terms of employee productivity when serving the BOP market. This is important in a bid to determine how to effectively operate at the BOP given the market’s unique characteristics.
Design/methodology/approach
This study uses two methods depending on the research question. First, a one-way analysis of variance (ANOVA) is used to determine the different employee-client categories based on socio-economic status. Second, fixed effects analyses are performed based on these categories to determine the most suitable employee-client category.
Findings
The results show the existence of employee-client matching based on similar socio-economic status. However, multivariate testing reveals that the mismatch category, where employees are of higher socioeconomic status than the clients, generates more favourable employee productivity. Moreover, this result may be contingent on the geographical location of the firm.
Practical implications
The findings are important for human resource management particularly the employment strategy of BOP firms. It suggests the need to consider employee profiles and client profiles when deciding which new markets to target.
Originality/value
The paper uses a global database of microfinance institutions as a case of BOP firms to investigate employee-client matching at the bottom of the pyramid.

Abstract
Purpose
The purpose of this paper is to propose a general approach for the frequency‐domain homogenization of electromagnetic periodic structures. The method allows calculating macroscopic equivalent properties including local effects. It is based on the equivalence of active and reactive electromagnetic powers on an elementary cell. This work is applied to the modelling of eddy current losses in windings, by the use of the finite element method in 2D and 3D.
Design/methodology/approach
The approach is based on an homogenization technique, allowing describing local properties (permeability and conductivity) and local effects (eddy currents) of periodical structures, through macroscopic homogenized behaviour laws.
Findings
It was found that the presence of local loops of eddy currents at the local scale implies that the average values of the electric and magnetic field are different from the macroscopic fields. This implies some precautions to implement the homogenization. Furthermore, the question of the coupling of the macroscopic laws has been clarified.
Research limitations/implications
The proposed method is limited to the frequency domain. Some additional work is necessary to extend the researches in the time domain.
Practical implications
The proposed methodology is applied for determining losses in coils with the finite element method. The major interest of the method is that it allows taking into account local effects (losses in particular), with a reduced computational time.
Originality/value
The method proposed in this paper is general and clarifies the principle of homogenization in the case of periodical structure in presence of local eddy currents (local loops of current).

Abstract
Purpose
This research aims to address the transformative service research (TSR) agenda by examining the issue of caste-based financial exclusion in microcredit lending services in India. To do so, it draws on statistical discrimination theory from labour economics to develop and test a multi-level prosocial service orientation framework.
Design/methodology/approach
Survey data come from 238 loan officers and 250 lower caste loan applicants across 43 microfinance institutions (MFIs) in India. The data are analysed using hierarchical linear modelling, a method appropriate for investigating micro- and macro-level organisational variables.
Findings
At the micro level, the service orientation factors of social dominance orientation and algorithmic-driven lending decisions affect financial exclusion of lower caste bottom-of-the-pyramid (BoP) vendors. At the macro level, the service orientation mechanism of inclusive service climate reduces caste-based financial exclusion, while the level of lending risk to reduce discrimination receives no support.
Research limitations/implications
Research in other contexts is warranted to confirm the prosocial service orientation model. Methodological challenges at the BoP also present avenues for insightful work.
Social implications
The study shows the importance of an inclusive service climate and reassessment of algorithmic-driven lending decisions to eliminate caste-based indicators in lending decisions. It also recommends policy reform of caste-based affirmative action at the macro- and micro-levels of lending decisions.
Originality/value
This research extends the TSR agenda to include caste-based discrimination in prosocial services. It takes a multidisciplinary perspective on services research by incorporating statistical discrimination theory from labour economics to extend understanding of service orientation.

Abstract
Purpose
The purpose of this study is to explore how vulnerabilities arising from physical impairments, age, widowhood, forced displacement due to war or natural disasters and sexual orientation affect women’s microfinance-related entrepreneurial activities and economic empowerment.
Design/methodology/approach
This paper is a structured literature review and uses preferred reporting items for systematic reviews and meta-analyses (PRISMA) method. The paper also uses agency, resources and achievement dimensions of empowerment to assess the findings.
Findings
This study reveals that although microfinance services promote women entrepreneurship, they also exacerbate exclusion and further discrimination. Individual-, household-, institutional- and community-level structures shape women’s agencies to access and use loans and conduct entrepreneurial activities; hence, ultimately economic empowerment.
Originality/value
The originality of this paper arises from the conceptual model we synthesised from our review which illustrates how vulnerable women’s agency is shaped by resources and how it affects their achievements in relation to entrepreneurial activities.

This paper aims to assess the effects of external governance mechanisms on the performance of microfinance institutions (MFIs) in Togo.
Abstract
Purpose
This paper aims to assess the effects of external governance mechanisms on the performance of microfinance institutions (MFIs) in Togo.
Design/methodology/approach
Using annual time series data from a sample of 30 MFIs during the period 2011–2015, the authors apply panel data econometrics in their estimations.
Findings
The results indicate that the notation by a rating agency positively and significantly affects the financial return of MFIs. The quality and the regularity of the audits negatively and significantly influence the financial performance (measured by return on assets and operating self-sufficiency) but favorably and significantly influence social performance (increased number of active borrowers (NAB) and reduced size of loans). Furthermore, supervision increases the amount of individual loans but decreases the NAB, which means deterioration in social performance. Overall, this paper shows that external governance mechanisms significantly affect the performance of Togolese MFIs, but with varying effects depending on the mechanism considered.
Research limitations/implications
The sample size of 30 MFIs is small, and the geographic coverage of the study is restricted to MFIs operating in the city of Lomé, Togo. The authors did not have access to the information regarding the portfolio at risk at 30 days, even though it is a measure of financial performance. Likewise, we did not have access to the appendices to the financial statements for the calculation of prudential ratios. This method, which consists of asking the institutions using a questionnaire if they comply with prudential standards, may be biased because this study cannot verify the authenticity of the responses given that the standards are quantitative.
Practical implications
The study findings advocate that improving the financial and social performance of MFIs requires improving the quality of external governance mechanisms. MFIs should then pay close attention to well-functioning external governance mechanisms.
Social implications
As MFIs are key social actors in a society, all mechanisms that contribute to their efficiency benefit society.
Originality/value
This study contributes to the corporate governance literature by showing that external governance mechanisms influence performance. These external mechanisms are complementary disciplinary measures to internal governance mechanisms and other tools.

Abstract
Two sets of dual magnetodynamic and magnetostatic finite element formulations taking thin conducting magnetic shells into account are proposed. The abstraction of the thin region from the computational domain is performed by an appropriate treatment of the surface integral terms arising in the weak formulations. Results are presented for two three‐dimensional test‐problems.

Abstract
Purpose
With exclusive data from a commercial microfinance institution (MFI) in Madagascar, the purpose of this paper is to investigate if loan officer rotation (change of loan officer) has an effect on credit access (loan approval) in rural and in urban areas. The authors further analyze how the frequency of loan officer rotation affects credit access in rural and in urban areas.
Design/methodology/approach
The authors apply propensity score matching to compare credit access between loan applicants who experienced loan officer rotation and loan applicants who experienced no loan officer rotation in rural and in urban areas.
Findings
Results show that loan officer rotation has a positive and statistically significant effect on credit access. The authors observe further that loan officer rotation has a different effect on credit access in rural and in urban areas. Whilst rural loan applicants who experienced loan officer rotation are more likely to have credit access, urban loan applicants show no statistically significant effect of loan officer rotation on credit access. For the frequency effect on credit access, the authors observe that one loan officer rotation has a positive and statistically significant effect on credit access whereas results are mixed for two loan officer rotations.
Research limitations/implications
Even though the authors can show that loan officer rotation can improve credit access to loan applicants, especially in rural areas, the conditions in Madagascar are unique. Therefore, results need to be verified in other countries and institutional contexts.
Practical implications
From the perspective of MFI, the authors recommend that the management of MFI needs to provide better tools to loan officers to improve on the evaluation of agricultural loan products or standardize the assessment of agricultural loan products to improve on lending decisions. Further, if applicable, the authors recommend that MFI should consider using credit worthiness assessment procedures which rely less on loan officer’s judgment for loan evaluation, such as automated systems. From the perspective of loan applicants, the authors recommend that loan applicants should request for a change of loan officer if they experience successive loan applications rejection.
Originality/value
To the authors’ knowledge, this paper is the first to provide empirical evidence on the effect and frequency of loan officer rotation on credit access in Sub-Sahara Africa, and Madagascar, in particular.

Abstract
Purpose
The aim of this paper is to model time‐harmonic problems in unbounded domains with coils of complex geometry and ferromagnetic materials.
Design/methodology/approach
The approach takes the form of a coupling between two integrals methods: the magnetic moment method (MMM) and the partial element equivalent circuit (PEEC) method. The modeling of conductor system is achieved thanks to PEEC method while the MMM method is considered for the magnetic material.
Findings
The paper shows how to use the MMM/PEEC coupled method to model a problem comprising conductors and ferromagnetic materials and compare its results with the FEM and the FEM/PEEC coupling.
Originality/value
The two methods PEEC and MMM are well‐known. The innovation here is coupling these methods in order to take advantages from both methods. Moreover, the performances of this coupling are studied in comparison with others (FEM, FEM/PEEC coupling).
