Impact of Access to Microcredit on Small Enterprise Growth in Lagos, Nigeria

Thesis Abstract

Access to microcredit has been promoted as a catalyst for small enterprise development, yet its actual impact on growth trajectories in dense urban economies remains contested. This study investigates the extent to which microcredit accessibility influences the growth of small enterprises in Lagos, Nigeria, addressing the gap between microfinance availability and measurable business performance in a rapidly urbanizing context. The aim is to quantify the relationship between microcredit access and enterprise growth, while unpacking the channels through which credit constraints, repayment terms, and financial literacy affect firm expansion, productivity, and profitability. Specific objectives include (1) estimating the effect of microcredit access on annual sales growth and employment size; (2) assessing the mediating role of working capital management and investment in productive assets; (3) examining heterogeneity by sector, firm age, and gender of the proprietor; (4) evaluating the moderating influence of financial literacy and collateral requirements; and (5) identifying policy-relevant constraints faced by microfinance institutions in Lagos. The study employs a cross-sectional survey design complemented by a qualitative component to illuminate contextual mechanisms. The population comprises formal and informal microenterprise owners operating in Lagos Metropolis with annual revenues up to 50 million naira. A stratified random sample of 420 enterprises is drawn from municipal clusters representing manufacturing, services, and trade sectors, with an embedded purposive subsample of 40 respondents who recently accessed microcredit from microfinance banks and non-bank microfinance institutions. Data collection combines structured questionnaires to quantify financial performance, credit history, and capital expenditure, with in-depth interviews to capture lender terms, trust dynamics, and perceived credit constraints. Validity and reliability of instruments are ensured through pre-testing, Cronbach’s alpha testing for multi-item scales, and triangulation with bank-issued credit data where available. Regression analysis, including ordinary least squares and fixed-effects models, is employed to estimate the impact of microcredit access on growth indicators (sales, profits, and employment), while Heckman selection correction addresses potential sample selection bias. Mediation analysis investigates the role of working capital and asset investment as pathways from credit access to growth. Subgroup analyses explore sectoral and demographic heterogeneity. The qualitative component undergoes thematic analysis to identify recurrent patterns in credit experiences, repayment terms, and institutional frictions, guided by the Resource-Based View and the Modigliani-Mrench framework on investment constraints. Expected findings anticipate a positive and statistically significant association between microcredit access and enterprise growth, with stronger effects for microenterprises in services and for firms led by male and younger proprietors. The study expects working capital enhancement and greater investment in productive assets to partially mediate the credit-growth relationship, while higher financial literacy and reasonable collateral terms amplify the effectiveness of microcredit. In contrast, stringent collateral requirements and inconsistent access across microfinance providers are anticipated to dampen potential gains, particularly for women-led enterprises. The contribution to knowledge lies in providing robust, context-specific evidence from Lagos that clarifies the conditions under which microcredit translates into tangible growth, distinguishes sectoral differences, and highlights institutional bottlenecks. The study also refines methodological approaches to measuring microcredit-driven growth in urban African economies, integrating quantitative results with qualitative insights to illuminate mechanisms and policy levers. Based on anticipated findings, the main conclusion is that microcredit access can meaningfully stimulate small enterprise growth in Lagos when accompanied by supportive financial literacy, appropriate loan terms, and streamlined access procedures. Recommendations include (1) simplifying collateral requirements and standardizing loan appraisal to reduce entry barriers; (2) integrating financial literacy training with microcredit programs to enhance value capture from borrowed funds; (3) encouraging product diversification toward asset-light and asset-intensive finance as appropriate to sectoral needs; and (4) fostering stronger collaboration between microfinance institutions and business development services to improve monitoring, repayment incentives, and information sharing.
