TL;DR: In this paper, the complementarity format is used in computable general equilibrium (CGE) modeling for a hybrid description of economy-wide production possibilities where energy sectors are represented by bottom-up activity analysis and the other production sectors are characterized by top-down regular functional forms typically belonging to the constant-elasticity-of-substitution (CES) family.

TL;DR: In this paper, a multiregional computable general equilibrium (CGE) model was applied to show that the efficiency argument for the use of grandfathered permits depends crucially on the specification of international trade.
Abstract: Unilateral action to combat an international externality such as CO2 emissions produces efficiency losses through spill–over effects of carbon emission constraints on international markets. Emissions by non–participating countries may be increased through the relocation of energy–intensive production or reductions in the international oil price (so–called carbon leakage). Grandfathered emission permit systems are considered as one unilateral mitigation strategy which could avoid carbon leakage and increase efficiency of global CO2 reduction as compared to unilateral uniform CO2 taxes. This paper summarises results from a multiregional computable general equilibrium (CGE) model application [1] which show that the efficiency argument for the use of grandfathered permits depends crucially on the specification of international trade.

TL;DR: In this paper, the authors compare the projections reported in a recent study by the European Commission with projections reflecting more conservative assumptions about the future energy markets and conclude that the alternative projections have a major impact on the magnitude and distribution of abatement costs.
Abstract: The on going climate change negotiations explicitly recognize the importance of the participating countries’ starting points. Another central factor for cost estimates of climate change policies is what happens under business as usual. Unfortunately, both factors are extremely uncertain. What are the possible cost implications in the EU of two alternative projections of future energy markets? In an otherwise identical model we contrast the projections reported in a recent study by the European Commission with projections reflecting more conservative assumptions about the future energy markets. We conclude that the alternative projections have a major impact on the magnitude and distribution of abatement costs. Specifically, we find that the optimistic EC projections imply significantly lower abatement costs. The EC projections also imply that country-specific assumptions about energy efficiency improvements and fuel mix changes in power generation may dominate the cost implications of the differential abatement targets currently adopted by the EU member countries.

TL;DR: In this paper, the IKARUS-Instrumentarium (ECOLOG II) has been used for the integration of E³Net in the instrumentarium of the University of Stuttgart.
Abstract: Ziel des Forschungsvorhabens „Einbindung des ECOLOG-Modells ‘E³Net’ und Integration neuer methodischer Ansatze in das IKARUS-Instrumentarium (ECOLOG II)' war es, veschiedene Modellbildungsansatze und Werkzeuge fur die energiewirtschaftliche Analyse zu einem Instrumentarium zusammenzufugen. Dazu wurde auf die Projekte IKARUS „Instrumente fur Klimagasreduktionsstrategien' und ECOLOG „Entwicklung eines Computermodells mit linearer Optimierung zur Abbildung eines regionalisierten Energiesystems am Beispiel Gesamtdeutschlands' aufgebaut. Das Projekt ECOLOG II umfast Weiterentwicklungen in den folgenden sechs Aufgabenbereichen: (1) Integration von E³Net in das IKARUS-Instrumentarium; (2) Nichtlineare Modellansatze fur E³Net; (3) Makrookonomische Erweiterung von E³Net; (4) Entwicklung und Anwendung eines multisektoralen Energiewirtschaftsmodells NEWAGE; (5) Entwicklung eines Simulationsansatzes fur Energiesystemmodelle PlaNet; (6) Erweiterung der Analysemoglichkeiten von NetWork. Im Rahmen des Forschungsvorhabens wurden eine Kopplung der FIZ-Technik-Datenbank an die Datenbank NetWork, eine Verbindung der FIZ-LP-Datenbank mit NetWork, eine Uberfuhrung des IKARUS-LP-Datensatzes in eine Fallstudie fur das optimierende Energiesystemmodell E³Net, ein optimierendes Energiesystemmodell mit preiselastischer Nachfrage E³Micro, ein Gleichgewichtsmodell NEWAGE, das prototypisch ein prozestechnisches Energieversorgungsmodell in ein ubergeordnetes gesamtwirtschaftliches Modell integriert, ein Simulationsmodell PlaNet sowie ein Netzwerkdesigner und -analyst (NDA) realisiert und durch exemplarische Fallstudien, die im Kontext des IKARUS-Instrumentariums stehen, getestet.
