We analyze optimal monetary policy when a central bank has to learn about an unknown coefficient that determines the effect of surprise inflation on aggregate demand. We derive the optimal policy under active learning and compare it to two limiting cases-certainty equivalence policy and...

Biogasproduktion wird in Deutschland mit dem Ziel des Klima- und Umweltschutzes sowie der Substitution fossiler Energieträger durch das Erneuerbare-Energien-Gesetz (EEG) gefördert. Dieser Beitrag analysiert quantitativ durch Kopplung eines Agrarsektor- und eines Standortmodells die...

Most dynamic trade models assume steady state or balanced growth. This paper argues while this can be done in a single region model or a model without trade, the steady state assumption is problematic in a multi-regional setting with trade interactions. This paper shows the consequences of...

'Desert Power 2050' is probably the world's most ambitious strategy report towards the decarbonization of the power sector in Europe, the Middle East and North Africa (EUMENA). The report inspired by the Desertec vision aims at providing clean energy from MENA's desert regions to the entire MENA...

A simple model is used to illustrate the effects of a reduction in (marginal) abatement cost in a two country setting. It can be shown that a the country experiencing a cost reduction can actually be worse off. This holds true for a variety of quantity and price based emission policies. The most...

For analyzing the impact of climate change and of international climate policies on the international division of labor and on regional welfare the use of a disaggregated multi–sectoral, multi–regional dynamic computable general equilibrium model is appropriate. This paper discusses the...

After the conferences in Bonn and Marrakech it is likely that international emission trading will be realized in the near future. Major influences on the permit market are the institutional detail, the participation structure and the treatment of hot air. Different scenarios do not only differ...

Since the study of Ellerman and Decaux (1998) marginal abatement cost curves (MACCs) have become one of the favorite instruments to analyze the impacts of the implementation of the Kyoto Protocol and emission trading. This paper shows that the MACC in one country depends - via the link of world...

The DART model is a multi-sectoral, multi-regional dynamic computable general equilibrium model of the world developed for the analysis of international climate policies. Since the first version of DART was developed at the Kiel Institute for World Economics in 1998, the model has undergone a...

This paper provides a technical description of GEM-PIA, a recursive-dynamic computable General Equilibrium Model for Poverty Impact Analysis in individual countries. The model combines the optimizing behavior of CGE models with the asset portfolio behavior of macromodels, thereby addressing the...
