This approach is applied to a case study in Europe represented by one of the biggest European public research organizations, the National Research council of Italy. Results suggest that funding for research (state subsidy and public contracts) of this public research organization is mainly consumed for the cost of personnel. In addition, the analysis shows a disproportionate growth of the cost of personnel in public research labs in comparison with total revenue from government. In the presence of shrinking public research lab budgets, this organizational behavior generates inefficiencies and stress. R&D management and public policy implications are suggested for improving economic performance of public research organizations in turbulent markets.
