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...

We compare the causal effects of forward guidance communication about future interest rates on households' expectations of inflation, mortgage rates, and unemployment to the effects of communication about future inflation in a randomized controlled trial using more than 25,000 U.S. individuals...

We take a monthly panel of German firms over the period 1980-2017 to examine the relative importance of time and state dependence in the decisions of firms to raise, lower or leave their price constant. In addition, we seek to estimate the relative importance of macroeconomic factors and...

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...

Rising government debt levels around the world are raising the specter that authorities might seek to inflate away the debt. In theoretical settings where fiscal policy “dominates” monetary policy, higher debt without offsetting changes in primary surpluses should lead households to...

Using a large-scale survey of U.S. households during the Covid-19 pandemic, we study how new information about fiscal and monetary policy responses to the crisis affects households' expectations. We provide random subsets of participants in the Nielsen Homescan panel with different combinations...

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...
