What is new ? • The analyses of the innovation-productivity relationship in the services context • With a structural model • Considering the characteristics of the data • 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
