Epidemics in the Neoclassical and New Keynesian Models
Martin S. Eichenbaum, Sergio Rebelo, Mathias Trabandt
Abstract
We analyze the effects of an epidemic in three standard macroeconomic models. We find that the neoclassical model does not rationalize the positive comovement of consumption and investment observed in recessions associated with an epidemic. Introducing monopolistic competition into the neoclassical model remedies this shortcoming even when prices are completely flexible. Finally, sticky prices lead to a larger recession but do not fundamentally alter the predictions of the monopolistic competition model.

Expectation Formation, Financial Frictions, and Forecasting Performance of Dynamic Stochastic General Equilibrium Models

Historical Social Research,
Special Issue: Governing by Numbers
2019
Abstract
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, such as price and wage rigidities, contribute to forecasting performance. It turns out that neither alternative expectation formation behaviour nor financial frictions can systematically increase the forecasting performance of basic DSGE models. Financial frictions improve forecasts only during periods of financial crises. However, traditional price and wage rigidities systematically help to increase the forecasting performance.

Wirtschaft im Wandel,
Nr. 1,
2014
Abstract
Am 2. und 3. Dezember 2013 fand am IWH in Zusammenarbeit mit dem Centre interuniversitaire de recherche en économie quantitative (CIREQ), Montréal, und der Martin-Luther-Universität Halle-Wittenberg der 14. IWH-CIREQ Macroeconometric Workshop statt. Im Rahmen des Workshops stellten Wissenschaftler und Wissenschaftlerinnen europäischer Universiäten und internationaler Organisationen, wie z. B. der Europäischen Zentralbank und der Europäischen Kommission sowie der spanischen, kanadischen und japanischen Zentralbanken, ihre neuesten Forschungsergebnisse im Bereich makroökonometrischer Modellierung und Prognose unter Berücksichtigung großer und komplexer Datenbanken vor. Auch wurden weitere makroökonomische Themen wie beispielsweise die Wirkung geldpolitischer Schocks oder Wechselkurs-Volatilitäten diskutiert.
