Establishment Size Distribution Analysis Summary

This study examines establishment size distribution across 27 European Union countries, focusing on factors influencing differences between higher- and lower-income regions.

Key Findings:

1. Income Level-Size Relationship: Using World Bank Enterprise Surveys and Eurostat data, establishment mean size (based on employment) positively correlates with GDP per inhabitant at both national and regional (NUTS1/NUTS2) levels. Doubling GDP per capita is associated with a ~80% increase in mean establishment size.
2. Regional Disparities: Higher-income countries (e.g., Denmark, Luxembourg) exhibit larger establishments (~59 workers) compared to lower-income ones (e.g., Poland, Greece, ~13-17 workers). Within the EU, Germany has the highest proportion of small establishments.
3. Determinants: Establishment size is influenced by:
   • Age: Older establishments are larger.
   • Female Top Managers: Female-led establishments are smaller on average.
   • Foreign Ownership: Higher ownership correlates with larger establishments.
   • Exports/Multi-establishment Firms: These positively influence size.
   • Sector: Manufacturing share does not significantly explain size variations at NUTS1 level.
4. Employment Concentration: Employment shares in top 10% establishments are higher in wealthier countries (~58%), reflecting better resource allocation. Right tail thickness of size distributions also increases with income.
5. Policy Implications: Size-correlated distortions appear systematic across EU regions (e.g., Germany's labor regulations). Addressing these could improve reallocation efficiency.

Conclusion: Resource misallocation due to female bias or regulatory hurdles explains smaller establishments in lower-income regions. Establishment size distributions consistently align with growth models, suggesting further analysis of underlying policies for enhanced productivity.
