Carbon Trading vs. Direct Allocation:  Theory and Application to China's Carbon Abatement

The Emission Trading System (ETS) and Direct Allocation Scheme (DAS) are two popular schemes to achieve a given target of carbon abatement. We compare their welfare implications under incomplete information and with local externalities of such abatement (e.g., changes in air pollution). We show that the ETS addresses incomplete information but not heterogeneous local externalities; the opposite is true for the DAS. Therefore, the policy choice depends on the relative significance of incomplete information and heterogenous local externalities. We apply the theoretical results to the Chinese data and discuss why a national ETS can be undesirable.
