• Compare previous quantitative services studies
Limitations
• Pure cross-section
• Proxis for labor productivity and innovation output
Any conclusions, so far? ......
• Endogeneity is a major problem
• The choice of instruments is critical for the results
• The model is highly sensitive to different estimation methods
Developments
• Further tests to determine the best specification and estimation method
• Test for structural changes in the model• Extend the model and consider other
countries – SIEPI database• Use a value added measure for
productivity• Combine CIS3 survey with CIS2 to build a
panel data set
