Regulating greenhouse gas emissions by an intertemporal policy mix: An experimental investigation
Tiho Ancev and
No 2015-17, Working Papers from University of Sydney, School of Economics
Incentive-based policies, such as emissions taxes and emissions permit trading schemes, are increasingly used to regulate greenhouse gas (GHG) emissions in many jurisdictions around the world. Taxes impose a fixed price on emissions, whereas under tradable permit schemes prices emerge in the secondary permit market. The delayed price discovery under tradable permit schemes creates uncertainty about the future cost of compliance that liable emitters will face. To mitigate this uncertainty, some jurisdictions, including Australia, have designed policies to regulate GHG emissions that commence with an emissions tax that is in force for several years, subsequently transforming into a tradable permit scheme. This paper examines the effects that this type of staged transition – from no regulation to a regulation by an emissions tax, to a regulation by tradable permits – has on several criteria of interest: abatement investment, quantity of emissions, permit prices and overall regulation efficiency. The effects of the regulation that employs an intertemporal mix of policy instruments are compared to the effects observable under regulation using single policy instrument: a tax only, and a tradable permit only regulation. Economics experiments in a laboratory were used to study economic behaviour under these three types of regulation. The findings suggest that a regulation based on a staged transition from a tax to a tradable permit scheme results in more socially desirable outcomes on a range of criteria when compared to a regulation based solely on tradable permits.
