Abstract:
In a three-country model in which export countries adopt environmental policies, this note analyses how abatement ("green") subsidy can become a potential strategic trade policy tool. When governments set the optimal policy tool considering their local environmental damages, a rich set of equilibria arise. In contrast to the standard result, it is shown that subsidising pollution abatement can 1) emerge as a Pareto-efficient equilibrium of the game; and 2) be the only feasible environmental policy when environmental awareness is low, irrespective of the technological efficiency. Therefore, "green" subsidies can lead to a win-win situation.
