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
