Ratio Working Paper No. 351: Knowledge Spillovers in the Solar energy sector
Working Paper 351.Solar Spillover.JGLadda ner
The purpose of this paper is to provide an analysis of the existence and possible direction of international knowledge spillovers in the solar energy sector. Specifically, the paper investigates how the accumulation of solar energy patents and public R&D spending affected the output of domestic granted solar energy patents. The econometric analysis relies on a data set consisting of most of the OECD countries plus China and analyzes two time periods; from 1990 to 2014 and the years 2000 to 2014. To analyze the data material, a Poisson fixed-effects estimator based on the Hausman, Hall and Griliches (1984) method was used. The empirical findings suggest that the domestic accumulation of patents and R&D is important for the potential development of new ones. Indeed, early investment in specific technology can be an indicator of future leadership in that field.
