From Industrial Ladders to Post-Industrial Manifolds: A Geometric Reconstruction of Economic Complexity Through Multi-Layer Fitness

This repository contains the consolidated replication package for the research article: "From Industrial Ladders to Post-Industrial Manifolds: A Geometric Reconstruction of Economic Complexity Through Multi-Layer Fitness", submitted to Structural Change and Economic Dynamics. File Contents (MLEF_Replication_Package.xlsx): This single repository file contains both the harmonized panel dataset and the full statistical output logs presented in the manuscript's Appendices. Data: Material ($F_M$) and Cognitive ($F_C$) Fitness scores (41 economies, 2007–2023). Appendix C: Counterfactual Analysis (Scalar vs. Cognitive metrics). SOM C: Distributional Diagnostics. SOM D: Panel Unit Root Tests (CIPS, PANIC). SOM F: System GMM Regression Outputs & Diagnostics. SOM G: Factor Analysis & Orthogonality Checks. SOM H: Markov-Switching VAR Regime Outputs. Methodology: The study applies the Multi-Layer Economic Fitness (MLEF) framework to decompose economic complexity into orthogonal capability axes and analyzes their interaction through dynamic panel estimation.
