Mit der geplanten Einführung des ETS2 im Jahr 2027, der dann auch die Sektoren Verkehr und Wärme umfasst, wird es wahrscheinlich für viele private Haushalte zu einer unmittelbar spürbaren und starken Steigerung der Ausgaben für CO2-Emissionen kommen. Geht man davon aus, dass die gesetzten...

Despite some progress, German macroeconomists are generally dissatisfied with access to important data in Germany. Legal, technical and organisational obstacles abound, in particular as far as mergers of data sets from heterogeneous sources are concerned. This article suggests a number of...

Die verlinkte Stellungnahme stellt heraus, welche Probleme beim Datenzugang aus makroökonomischer Perspektive bestehen. Hierzu zählt neben der verbesserungswürdigen Datenverfügbarkeit insbesondere die fehlende Möglichkeit der Datenverknüpfung. Lösungsansätze - beispielsweise die...

Using a German firm-level data set, this paper is the first to jointly study the cyclical properties of the cross-sections of firm-level real value added and Solow residual innovations, as well as capital and employment adjustment. We find two new business cycle facts: 1) The cross-sectional...

Is time-varying firm-level uncertainty a major cause or amplifier of the business cycle? This paper investigates this question in the context of a heterogeneous-firm RBC model with persistent firm-level productivity shocks and lumpy capital adjustment, where cyclical changes in uncertainty...

The sensitivity of U.S. aggregate investment to shocks is procyclical: the response upon impact increases by approximately 50% from the trough to the peak of the business cycle. This feature of the data follows naturally from a DSGE model with lumpy microeconomic capital adjustment. Beyond...

Microeconomic lumpiness matters for macroeconomics. According to our DSGE model, it explains roughly 60% of the smoothing in the investment response to aggregate shocks. The remaining 40% is explained by general equilibrium forces. The central role played by micro frictions for aggregate...
