RT Book, Section T1 Abatement Level in Environmental Agreements when Firms are Heterogeneous in Abatement Costs. A1 Gautier, Luis K1 Impuestos ambientales K1 Control de costes K1 Medio ambiente - Degradación AB There is an important number of regional and international environmental agreements wherecountries have agreed upon in order tackle environmental degradation (e.g., reduce greenhousegases). In addition, member countries exhibit varying pollution abatement technologiesand degrees of pollution intensities as well as different cost structures. As new agreementstake place (e.g., COP21 Paris) and existing ones evolve as climate and economic conditionschange, the analysis of policy reform of environmental policy becomes timely and relevant.With these in mind, this paper builds a two-country model where rms compete in a Cournotfashion, face an emission tax and exhibit heterogeneous abatement costs. In this context,the analysis of policy reform is presented, particularly its impact on global emissions. It isshown that asymmetries in abatement and production costs play a crucial role on the extentto which global emissions fall via unilateral and multilateral policy reform.
