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...

The 'deforestation problem' in Brazil consists of a variety of interrelated issues, of which this paper identifies a regional, sectoral and macroeconomic dimension. Using a regionally and sectorally disaggregated general equilibrium model of Brazil, it is shown that macroeconomic reform is...

This paper sets up a multiregional dynamic framework by combining the optimal savings model with investment adjustment costs and the spatially disaggregated model with Dixit-Stiglitz structure in the modern sector. Because of increasing product diversity on the dynamic equilibrium path, the...

This paper provides a technical description of the Dynamic Applied Regional Trade (DART) General Equilibrium Model. The DART model is a recursive dynamic, multi-region, multi-sector computable general equilibrium model. All regions are fully specified and linked by bilateral trade flows. The...

Unlike in Asia, the manufacturing sector has not (yet) become a driver of structural change in Africa. One common explanation is that the natural resource-focus of many African economies leads to Dutch disease effects. To test this argument for the case of newly found oil in Ghana we develop a...

In the context of energy security and climate protection, biomass is given high importance. Nevertheless, land-use conflicts resulting from the cultivation of biomass and their economy-wide effects are yet to be fully understood. To shed light on this issue we link three distinctive models; a...

We explore the uses of double-calibrated general equilibrium models as a decomposition tool for analysing contributory factors in the growth and increasing wage inequality in an advanced economy (the UK) since 1979. Calibration of a model to start and end years, based upon an assumed functional...

This paper provides a model-based assessment of local and global climate change impacts for the case of Yemen, focusing on agricultural production, household incomes and food security. Global climate change is mainly transmitted through rising world food prices. Our simulation results suggest...

In order to reach the two degree target it is necessary to control CO2 emissions also in fast growing emerging economies such as India. The question is how the Indian economy would be affected by e.g. including the country into an international climate regime. Existing analyses with either a...
