We develop a novel approach integrating epidemiological and economic models that allows databased simulations during a pandemic. We examine the economically optimal opening strategy that can be reconciled with the containment of a pandemic. The empirical evidence is based on data from Germany...

The budget dispute between Italy and the European Commission in 2018 gave new impetus for the debate about the reliability of output gap estimation methods and their use for calculating structural budget balances. In this paper we review the main properties of the mainstream approaches and...

The highly dynamic nature of the COVID-19 crisis poses an unprecedented challenge to policy makers around the world to take appropriate income-stabilizing countermeasures. To properly design such policy measures, it is important to quantify their effects in real-time. However, data on the...

This paper studies the determinants of firms' business outlook and managerial mitigation strategies in the wake of the COVID-19 crisis using a representative panel of German firms. We first demonstrate that the crisis amplifies pre-crisis weaknesses: Firms that appear relatively weak before the...

COVID-19 hit firms by surprise. In a high frequency, representative panel of German firms, the business outlook declined and business uncertainty increased only when the spread of the COVID-19 pandemic led to domestic policy changes: The announcement of nation-wide school closures on March 13...

We leverage survey data from Germany, Italy, and the US to document several novel stylized facts about the extent of information frictions among firms and households. First, firms’ expectations about the central bank policy rate, inflation, and aggregate unemployment are more aligned with...

Attention to the economy plays a key role in canonical macro models, yet its empirical properties are not well understood. We collect novel measures of attention to the economy based on open-ended survey questions. Our measures are included in tailored panel surveys of German firms and...

This paper estimates the causal effect of corporate tax hikes on firm investment based on more than 1,400 local tax changes. By observing planned and realized investment volumes in a representative sample of German manufacturing firms, we can study how tax hikes induce firms to revise their...

This paper addresses the credit channel in Germany by using aggregate data. We present a stylized model of the banking firm in which banks decide on their loan supply in light of uncertainty about the future course of monetary policy. Applying a vector error correction model (VECM), we estimate...

This paper presents a micro data approach to the identification of credit crunches. Using a survey among German firms which regularly queries the firms' assessment of the current willingness of banks to extend credit we estimate the probability of a restrictive credit supply policy by time...
