Knowledge Accumulation from Public Renewable Energy R&D in the European Union: Converging or Diverging Trends?
(English)Manuscript (preprint) (Other academic)
The objective of this paper is to investigate the presence of convergence (or divergence) in public renewable energy R&D spending accumulation in 12 Member States of the European Union (EU) and an extended set of 17 OECD countries. Specifically, we employ a data set covering the period 1980-2012. The motivation for investigating convergence in the selected countries are in part due to the political economy of imposing stricter targets for renewable energy. The method draws inspiration from the classic economic convergence literature. Various empirical specifications for conditional β-convergence is tested. The empirical results suggest divergence in public R&D-based knowledge accumulation, and this is consistent with free-riding behavior on the part of some Member States. Energy import dependence and electricity regulation also affect the divergence pattern, e.g., the speed of divergence.
