Abstract:
The purpose of this paper is to compare the effect of different domestic climate policy instruments under asymmetric information when the regulator wants to secure the survival of a specific firm. It is a well-known result from economic theory that emission taxes lead to a cost-effective distribution of abatement across polluters. However, if the regulator wants to ensure the survival of a specific firm, it may need to design policy instruments that reduce the firm's cost of complying with an emission tax regime. The climate policy instruments considered in this paper are tradable emission permits with distribution of free permits, emission taxes in combination with a fixed subsidy, and two types of voluntary agreements. It demonstrates first that if distributing free tradable permits shall have a preventing effect, the allocation of permits has to be made contingent on production. It further shows that a voluntary agreement where a specific abatement target is set by the regulator can prevent a shutdown but leads to lower welfare than the use of emission taxes in combination with a fixed subsidy. And finally it illustrates that a voluntary agreement designed as a menu of abatement contracts increases social welfare compared to an emission tax regime.

Abstract:
Strategic market behavior by permit sellers will harm the European Union as the EU as a whole is expected to become a large net buyer of permits in a follow-up agreement to the Kyoto Protocol. In this paper we explore how the EU could benefit from making permit trade agreements with non-EU countries. These trade agreements involve a minimum permit sales requirement complemented by a financial transfer from the EU to the other contract party. Such agreements enable the EU to act strategically in the permit market on behalf of its member states, although each member state is assumed to behave as a price taker in the permit market. Using a stylized numerical simulation model we show that an appropriately designed permit trade agreement between the EU and China can cut EU’s total compliance cost significantly. This result is robust for a wide range of parameterizations of the simulation model.
