SME corporate governance: a literature review of informal mechanisms for governance

Purpose - This paper takes a structured literature review (SLR) approach to identify gaps in the literature and suggest future research opportunities. It focuses on corporate governance (CG) performed outside the formal board of directors' structure and examines research of alternative CG of small andmedium-sized entities (SMEs). Design/methodology/approach - The authors use the SLR method to search the Scopus database, extracting and synthesising findings relating specifically to SMEs' CG. These are tabulated and described using bibliometric software. Findings - The authors highlight an absence of tailored theoretical approaches to understanding CG in SMEs, which differs from the governance of larger entities. They also find evidence of alternative governance structures in SME CG. Research limitations/implications - Further research should embrace management and other theoretical perspectives and expanded methodologies, nuances in understanding offered in contextualised settings and awareness of practical implications to better understand the specific setting of CG in SMEs. Practical implications - SMEs seek to access the scarce resources and skills external to their formal CG structures. Regulators and resource providers should mobilise facilitation and training for this expansion. Originality/value - The authors synthesise a large body of literature to extract findings specific to SMEs. A unique contribution is our focus on alternative forms of CG in SMEs. Evidence of alternative boards points to resolutions for human capital shortages in SMEs.
