Structural Determinants of Economic Complexity
Overview
This completed group report studies the structural correlates of productive sophistication across countries in 2022. It links economic complexity to human development, institutions, inequality, trade openness, financial freedom, and population.
Research Question
Which structural and socioeconomic factors are associated with cross-country differences in the Economic Complexity Index?
Economic or Technical Motivation
Economic complexity captures accumulated productive capabilities, but its cross-country variation may reflect both market integration and the institutional and human foundations that allow knowledge to diffuse and combine.
Data
The final OLS sample contains 108 countries for 2022. Variables combine the OEC Economic Complexity Index with UNDP human-development data, World Governance Indicators, World Inequality Database measures, World Development Indicators, and financial-freedom data.
Methodology
The report uses cross-sectional OLS, descriptive statistics, correlations, joint significance tests, and a developing-economy subsample. The model includes HDI, regulatory quality, income inequality, trade openness, log financial freedom, and log population.
Main Findings
The baseline estimates report positive associations for HDI (2.363), regulatory quality (0.468), trade openness (0.0071), and log population (0.278), and a negative association for inequality (-1.012). Financial freedom is imprecise. The model reports R-squared 0.707 and adjusted R-squared 0.689. The 97-country developing-economy subsample preserves the main signs and significance pattern.
Robustness, Validation, or Model Assessment
The study reports correlations, confidence intervals, a joint F-test, and a developing-economy subsample. It also documents the limits of the small developed-economy group rather than presenting an unstable comparison.
Tools and Technologies
Stata 17, OLS, cross-country data integration, hypothesis testing, and LaTeX report production are directly evidenced.
Limitations
The 2022 cross-section cannot establish temporal ordering or causal effects. Country-level averages conceal sectoral and subnational heterogeneity, and several regressors are strongly related to one another.
