Comments to:“Identifying R&D Shortfalls in LDC”Andrés Rodriguez-Clare Rodrigo Fuentes, Central Bank of Chile Barcelona, June 2005
Issues that I liked: • Technological improvement generates level-rather than growth rate effects • Several plausible hypotheses are checked • Policy implications are carefully derived • Comments • Hard to read • Distortions are important. How to include them? • Trade should affect the free flow of ideas • Conjectures and policy implications
TFP is the result of accumulation but also of complementarity of good policies and good institutions • Distortions are important. Are they properly included in the paper? • Meaning of z=1.1 for the case of Chile? • The parameter ε should depend on trade distortions (Edwards, 1992, Coe and Helpman, 1995, Keller, 1998) • Natural resources matters: mining sector is the most K-intensive sector
Source: Fuentes and Mies (2005) based on an index constructed by the World Bank. It includes literacy rate, and formal education enrollment
Index Source: Constructed by Mies and Fuentes (2005) based on WDI Quality of EducationKernel Distribution
Quality of Education Source: Fuentes and Mies (2005)
Conjectures • Credit market. Large companies do have access to credit • Lack of human resources. Quality of education • Policies and institutions. Private sector and research institutions collaboration. • Policies implications • Domestic versus international spillovers • The role of trade and financial policies • What to do in Chile and other LDC? There is not a unique policy rule
Comments to: “Patenting and R&D: A Global View”M. Bosch, D. Lederman, W. Maloney Rodrigo Fuentes, Central Bank of Chile Barcelona, June 2005
This paper • Empirical approach to determinants of innovation output, using US patents granted data • Empirical strategy is carefully implemented • Comments • Main result: long run elasticity equal to one for developed economies • Relation to previous paper? • Incentives to invest in R&D in LDC: measurement error of return to R&D • Check of robustness
Main result: surprisingly high long-run elasticity of patents respect to R&D for DC • Is this compatible with idea of externalities and spillovers? • Romer (1986) assumes increasing returns in the production of consumption good, but strong diminishing returns in the production of knowledge • The previous paper argues in favor of the importance of externalities, the findings of this one cannot be placed within a theoretical growth model with externalities
Incentives for the private sector to invest in R&D may not be related to obtain a patent in the US: • the target could be the domestic market or • the adaptation of new technology • The final section is quite important. It seems that the inclusion of NIS variable reduces the long-term elasticity
Suggestions: • It would be informative to present the elasticity and the standard error for some specific countries • Expected to see an estimation with the interaction between export to US and R&D variables
