The Model
List of Variables
Innovation Activities
Model Specification
Services Industries in Data Set
Sample Description
Sistem Estimation
Separate Estimation
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
