Does green policy pay dividends?

While there is a near global consensus about the need to address climate change, most countries are hesitant to employ sufficiently stringent policies in fear of sacrificing economic growth. The objective of this research is to examine the impact of environmental policy on economic growth, using the OECD's Environmental Policy Stringency (EPS) index across 21 OECD countries from 1990 to 2014. An augmented Solow Model with the inclusion of variables to represent human capital, trade openness and the EPS index is used to assess whether policy stringency affects growth with empirical analysis comprised of a pooled mean group estimator, dynamic OLS, fixed effects and pooled OLS to estimate the short and long run effects. The results reveal that policy stringency negatively affects economic growth in the short run but pays dividends of positive growth in the long run. There appears to be a threshold level of the EPS, beyond which the dividend is realized in the long run. The results are expected to be of interest to policy makers who strive to address climate change without trading off economic growth. [ABSTRACT FROM AUTHOR]
