The basic model of the literature on self-enforcing international environmental agreements is a model of autarkic countries. We extend that model by international trade and investigate its impact on the performance of Nash coalitions and on their stability, in particular, in a general...

Policies of lowering carbon demand may aggravate rather than alleviate climate change (green paradox). In a two-period three-country general equilibrium model with finite endowment of fossil fuel one country enforces an emissions cap in the first or second period. When that cap is tightened the...

Policies of lowering carbon demand may aggravate rather than alleviate climate change (green paradox). In a two-period three-country general equilibrium model with finite endowment of fossil fuel one country enforces an emissions cap in the first or second period. When that cap is tightened the...

We model EU-type carbon emissions control in a group of countries to explore the distributional incidence of mixed policies that consist of an emissions trading scheme (ETS) and of emissions taxes overlapping with the ETS. Such policies impact on national welfares through both the overlapping...

We study the incidence of carbon-reduction and green-energy promotion policies in a general equilibrium small open economy that depends on imports of fossil fuels. The focus is on mixed policies that are either price based (emissions taxes and producer price subsidies for green energy) or...

Scientific expertise suggests that mitigating extreme world-wide climate change damages requires avoiding increases in the world mean temperature exceeding 2° Celsius. To achieve the two degree target, the cumulated global emissions must not exceed some limit, the so-called global carbon...

We study the incidence of carbon-reduction and green-energy promotion policies in an open fossil-fuel importing general equilibrium economy. The focus is on mixed price-based or quantity-based policies. Instruments directed toward promoting green energy are shown to reduce also carbon emissions...

Internalizing the global negative externality of carbon emissions requires flattening the extraction path of world fossil energy resources (= world carbon emissions). We consider governments having sign-unconstrained emission taxes at their disposal and seeking to prevent world emissions from...

Ergänzend zu dem im ifo Schnelldienst 19/2001 diskutierten Thema »Klimaschutz - ist das Emissionshandelssystem ein effizientes Mittel zur Emissionsverringerung?« sind Prof. Dr. Uwe Schubert und Oliver Percl, Wirtschaftsuniversität Wien, der Ansicht, »dass beim derzeitigen Wissensstand die...

Der Stern-Report, der vierte IPCC-Bericht der UNO und nicht zuletzt der extrem warme Winter 2006/07 haben die Klimaproblematik wieder in de Mittelpunkt des öffentlichen Interesses gerückt. Welchen Beitrag kann und sollte Deutschland zur Lösung des Weltklimaproblems leisten? Die Antwort von...
