Effective climate policy can be achieved by implementing either a global uniform carbon price or a global cap and trade system. But depending on the allocation of tax revenues and initial pollution permits, the instruments have very different wealth implications for the individual countries. The...

We derive the optimal contributions to global climate policy when countries differ with respect to income level and pollution intensity. Countries growth rates are determined endogenously, and abatement efficiency is improved by technical progress. We show that country heterogeneity has a...

The paper develops the Basic Climate Economic (BCE) model featuring the core elements of climate economics and climate policy. The BCE model incorporates fossil stock depletion, pollution stock accumulation, endogenous growth, and climate-induced capital depreciation. We first use graphical...
