This paper considers the problem of aggregation in the case of large linear dynamic panels, where each micro unit is potentially related to all other micro units, and where micro innovations are allowed to be cross sectionally dependent. Following Pesaran (2003), an optimal aggregate function is...

On 3 June 2020, the German government announced a temporary value added tax (VAT) rate reduction. VAT rates were reduced on 1 July 2020 and went back to their previous level on 1 January 2021. We study the price effects of the temporary VAT rate reduction using a web-scraped data set covering...

The value-added tax is one of the most important tax revenue sources in many countries. However, it is sometimes considered unfair as it ultimately hits consumption, and poorer households spend a greater share of their income on consumption. But this depends on whether, and to what degree, the...

This paper provides insights into the time-varying dynamics of the German business cycle over the last five decades. To do so, I employ an open-economy time-varying parameter VAR with stochastic volatility, which I estimate by quasi-Bayesian techniques. The reduced-form analysis reveals...

This paper studies the importance of firm-level price markup dynamics for business cycle fluctuations. Using state-of-the-art IO techniques to measure the behavior of markups over the business cycle at the firm level, I find that markups are countercyclical with an average elasticity of -1.1...

We provide a comprehensive analysis of income inequality and income dynamics for Germany over the last two decades. Combining personal income tax and social security data allows us — for the first time — to offer a complete picture of the distribution of annual earnings in Germany. We find...

Using firm-level survey data from Germany, this paper asks how do supply constraints propagate monetary policy shocks? To answer this question, we first offer a general discussion on the measurement of supply constraints. We show that capacity utilization, a widely accepted measure of...

We analyze the effectiveness of the German tax reduction on fuel prices (‘Tankrabatt’) that was introduced for three months, starting on 1 June 2022. Using the synthetic control method to compare actual prices of gasoline and diesel to those in a counterfactual situation without the tax...

Germany’s comparatively good economic performance throughout the Great Recession of the years 2008/2009 is often attributed to the business model of the German Mittelstand firm. Somewhat surprisingly, this claim has never been backed by empirical evidence. In this paper we use micro panel data...

Since the 1980s inflationary pressures seem to materialize overproportionately outside of the sectors of consumer goods and services. We combine the Harmonized Index of Consumer Prices with indices for asset prices, such as stocks and real estate, as well as the costs of public goods to develop...
