Export competition and the remission of domestic environmental taxes

We consider the use of border adjustments to compensate exporters for domestic environmental taxes imposed on an intermediate good. A model of successive oligopoly is used to consider the appropriate border adjustments. In this set-up, the relative importance of the forward incidence of the environmental tax and the backward incidence of the remission play a key role. The results highlight that the simple rule employed by GATT/WTO to set the export remittance equal to the level of the environmental tax is likely to be inappropriate.
