We use a model of endogenous growth with vertical innovations in order to derive optimal energypolicy under uncertainty. Innovation can be directed to dirty, green or nuclear technologies, whichin turn can be used to produce different types of energy. We show that, nuclear energy usage is notonly a necessary welfare maximizing condition but also a crucial determinant of economic growthin the long-run. In addition, we find no evidence supporting the Environmental Kuznets Curvehypothesis under optimal policy implementation. Lastly, empirical results based on a panel VARspecification suggest that increases in emissions are strongly persistent in the long-run. Thus, aworsening of environmental quality seems to create dynamics that lead to even higher levels ofemissions in the future.
我们使用具有垂直创新的内生增长模型，以便在不确定性下得出最优的能源政策。创新可以针对肮脏的，绿色的或核技术，而反过来又可以用于产生不同类型的能源。我们证明，核能的使用不仅是最大化福利的必要条件，而且从长远来看也是决定经济增长的关键因素。此外，我们发现没有证据支持最佳政策实施下的环境库兹涅茨曲线假说。最后，基于面板VAR规范的经验结果表明，从长远来看，排放量的增加是持久的。因此，环境质量的恶化似乎会产生动力，从而导致未来排放水平更高。
