Im Spätsommer 2022 ist die Weltwirtschaft im Abschwung. Anhaltend hohe Inflationsraten haben die US-Notenbank und viele weitere Zentralbanken veranlasst, mit einer Straffung ihrer Geldpolitik zu beginnen. Zudem ist seit dem Ausbruch des Ukraine-Kriegs Energie knapper und teurer geworden....

In the fight against global warming, the reduction of greenhouse gas emissions is a major objective. In particular, a decrease in electricity generation by coal could contribute to reducing CO2 emissions. Using a multi-region dynamic general equilibrium model, this paper studies potential...

Die vorliegende Studie untersucht die ökonomischen Auswirkungen eines durch die Klimaziele der Bundesregierung induzierten Kohleausstiegs in Deutschland. Der Fokus liegt hierbei auf der Braunkohlenwirtschaft – insbesondere in den Braunkohleregionen. Ausgangspunkt sind Ausstiegspfade für die...

Der Ausblick auf die internationale Konjunktur 2023 ist verschattet: Die Energieversorgung Europas ist ungewiss, die Leitzinsen steigen weiter, der Pandemieausbruch in China führt zu Produktionsausfällen. Belastungen für die deutsche Wirtschaft kommen von hohen Energiepreisen und einem...

This paper examines the extent to which errors in economic forecasts are driven by initial assumptions that prove to be incorrect ex post. Therefore, we construct a new data set comprising an unbalanced panel of annual forecasts from different institutions forecasting German GDP and the...

In a multi-sector and multi-region framework, this paper employs a dynamic general equilibrium model to analyze climate-resilient economic development (DGE-CRED) in Vietnam. We calibrate sector and region-specific damage functions and quantify climate variable impacts on productivity and capital...

In recent years, the impacts of climate change become increasingly evident, both in magnitude and frequency. The design and implementation of adequate climate adaptation policies play an important role in the macroeconomic policy discourse to assess the impact of climate change on regional and...

Accurate macroeconomic forecasts are essential for effective policy decisions, yet their precision depends on the accuracy of the underlying assumptions. This paper examines the extent to which assumption errors affect forecast accuracy, introducing the average squared assumption error (ASAE) as...

In this paper, we document the forecasting performance of estimated basic dynamic stochastic general equilibrium (DSGE) models and compare this to extended versions which consider alternative expectation formation assumptions and financial frictions. We also show how standard model features,...
