In this paper we test whether German public debt has been sustainable by resorting to a test proposed by Bohn (1998). We apply non-parametric and semi-parametric regressions with time depending coefficients. This test shows that the mean of the coefficient relevant for sustainability has been...

To date, only annual information on economic activity is published for the 16 German states. In this paper, we calculate quarterly regional GDP estimates for the period between 1995 to 2021, thereby improving the regional database for Germany. The new data set will regularly be updated when...

Accurate real-time macroeconomic data are essential for policy-making and economic nowcasting. In this paper, I introduce a real-time database for German regional economic accounts (READ-GER). The database contains real-time information for nine macroeconomic aggregates and the 16 German states....

Using a randomized controlled trial, we study whether showing German respondents a graph plotting the European Central Bank's inflation target alongside inflation in the euro area from 1999 to 2017 affects respondents' trust in the ECB. The treatment has, on average, no significant effect on the...

This study identifies day-of-the-week effects in business surveys using monthly data from the ifo Institute. The odds are higher that companies are more likely to exhibit more pessimistic business expectations for the upcoming months on Mondays and more optimistic expectations at the end of the...

Using new survey data on quantitative growth expectations of firms in Germany, we show that firms resort to local information when forming expectations about aggregate growth. Firms extrapolate from the economic situation in their county, industry growth and their individual business situation....

States have soft budget constraints when they can expect a bailout by the federal government in the event of a financial crisis. This gives rise to incentives for unsound state fiscal policy. We test whether states with softer budget constraints have higher debt and deficits, receive more...

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...

Adaptation to climate change is gaining increasing relevance in the public debate of climate policy. However, detailed and regionalised cost estimates as a basis for cost-benefit-analyses are rare. We compose available cost estimates for adaptation in Europe, and in particular Germany, Finland...

In this paper we challenge the view that the oil price has lost its influence on economic activity after the mid-1980s. While we concede that typical VAR models put forward in the literature fail to identify oil price shocks that significantly affect aggregate production, we obtain clearly...
