1 ZEW Economic Effects of Co-ordinated and Non-co-ordinated Permit Schemes in an EU-Bubble An Applied General Equilibrium Analysis with the GEM-E3 Model Tobias F.N. Schmidt, ZEW

2 ZEW Overview of the Presentation l What is the issue to be analysed? l What are the characteristics of the GEM-E3 model? l What answers can the model give with respect to the issue analysed? l Which conclusions can be drawn?

3 ZEW What is the issue? l Burden sharing agreement of the EU Council of Ministers versus trading of emission rights. l What are the economic consequences of sticking to domestic action? l What are the impacts of trading of emission rights across the EU?

4 ZEW Table 1: EU Burden Sharing Agreement

5 ZEW Characteristics of GEM-E3 l CGE-model for studying economy-energy- environment interactions l Multi-country, multi-sectoral model (14 EU-countries, 18 sectors) l Open economies linked through bilateral trade flows l Social accounting framework l Recursively dynamic l Standard version: perfect competition

6 ZEW Production Structure in GEM-E3

7 ZEW Consumption in GEM-E3

8 ZEW Baseline and Scenario Assumptions l Baseline - 1.8% to 2.5% annual growth in the EU - increase of world energy prices l General scenario assumptions - 8% reduction of EU-wide 1990 CO2 emissions until Realisation through tradable emission permit schemes - Reduction & trade of permits realised during the budget period

9 ZEW Specification of the Permit Scheme l Initial allocation of permits: free of charge according to burden sharing agreement of the Council of Ministers. l Grandfathering across firms and households within the countries. l Marginal decision of polluters based on opportunity costs l Rents related to free-of-charge allocation of permits increase capital income

10 ZEW Policy Scenarios l Policy 1: No Trade non-co-ordinated domestic actions: national permit schemes l Policy 2: Free Trade co-ordinated action: EU-wide permit scheme, i.e. free trade of permits across member states

15 ZEW Table 5: Comparing Free Trade and No Trade

16 ZEW Reasoning l Buying or holding permits increases input prices for primary energy inputs --> distortion in intermediate demand. l Rents related to free-of-charge allocation and sale of permits increase capital income. l The distortionary effect of the former exceeds the re-distortion achieved by the latter.

17 ZEW Table 6: Trade of Permits and Ceilings l Ceilings: EU proposal l formula:

18 ZEW Conclusions I l Free trade of permits reduces the overall mitigation cost for the EU. l If trade is on the level of private entities, there are - compared to the no trade case - winners and losers of free trade: Net-buyers win, net-sellers lose. l Considering opportunity costs for holding permits produces distortions that are not fully compensated by the rents linked to the sale of permits (reasoning: public finance).

19 ZEW Conclusions II l An outcome based allocation rule of the overall gains could make all countries better off. l The issue of ceilings is of minor importance within the EU-bubble. l Under free trade of permits, only Greece and Portugal (net-sellers) would exceed the amount allowed by the EU proposal.
