Financial structure, risk, and firm performance: multilevel meta-analysis of empirical evidence from over three decades (1990-2024)

This dataset and R code was use to conduct a multilevel meta-analysis following the PRISMA methodological guideline to analytically synthesize empirical evidence from 1990 to 2024 to assess how financial structure and risk influence firm financial performance, and to compare effects across firms sizes, with a particular focus on SMEs, evaluate whether financial structures demonstrate significant moderating or mediating roles in shaping the impact of risk on firm performance, and determine whether certain performance measurement metrics exhibit greater sensitivity to variations in financial structure.
