Authors’s abstract :

Climate change must deal with two market failures, global warming and learning by doing in renewable use. The social optimum requires an aggressive renewables subsidy in the near term and a gradually rising carbon tax which falls in long run. As a result, more renewables are used relative to fossil fuel, there is an intermediate phase of simultaneous use, the carbon- free era is brought forward, more fossil fuel is locked up and global warming is lower. The optimal carbon tax is not a fixed proportion of world GDP. The climate externality is more severe than the learning by doing one.
