3.1 Research Design for Multi-Source Secondary Corridor Analysis
The methodological framework employs a structured comparative analysis of secondary corridor literature and published institutional evaluations to assess how digital intermediation shifts cost dynamics and financial inclusion outcomes [5]. Rather than relying on direct household sampling, the analytical model harmonizes cross-corridor cost tracking reports, regulatory publications, and documented financial integration programs to construct a standardized evaluation matrix [6]. This approach systematically reviews transactional fee components, exchange rate margins, and downstream banking adoption across diverse migratory channels [5]. By synthesizing comparative benchmarks from established banking ecosystems and cross-border digital operators, the study isolates the institutional factors that govern transfer efficiency [6]. The evaluation criteria categorize transaction barriers into infrastructural connectivity, regulatory compliance overhead, and institutional intermediation mechanisms, ensuring that findings reflect broad corridor structural patterns rather than localized operational anomalies [5]. Through rigorous qualitative synthesis and documentary cross-validation, the methodological strategy maintains robust analytical neutrality while capturing multi-country regulatory variability [6].
