The German economy is an important economic driver in the Euro-area in terms of gross domestic product, labour force and international integration. We provide a state of the art estimate of the German output gap between 1995 and 2022 and present a nowcasting scheme that accurately predicts the...

There has been increased interest in the use of "big data" when it comes to forecasting macroeconomic time series such as private consumption or unemployment. However, applications on forecasting GDP are rather rare. In this paper we incorporate Google search data into a Bridge Equation Model, a...

Data revisions to national accounts pose a serious challenge to policy decision making. Well-behaved revisions should be unbiased, small and unpredictable. This paper shows that revisions to German national accounts are biased, large and predictable. Moreover, using filtering techniques designed...

We present a comprehensive disaggregate approach for short-term forecasting economic activity in Germany by explicitly taking into account the supply or production side and the demand side of GDP. The GDP figures calculated by the two sides usually yield different results and the official GDP...

We study how millions of highly granular and weekly household scanner data combined with novel machine learning techniques can help to improve the nowcast of monthly German inflation in real time. Our nowcasting exercise targets three hierarchy levels of the official consumer price index. First,...

We draw on two decades of historical data to analyze how regional labor markets in West Germany adjusted to one of the largest forced population movements in history, the mass inflow of eight million German expellees after World War II. The expellee inflow was distributed very asymmetrically...

We study how the presence of a college affects the local economy using administrative data. Our analysis exploits the opening of new institutions of tertiary education across Germany in the 1980s and 1990s. The new college substantially increased the student population and share of high-skilled...

We characterize intergenerational mobility in Germany using census data on educational attainment and parental income for 526,000 children. Our measure of educational attainment is the A-Level degree, a requirement for access to university. A 10 percentile increase in the parental income rank is...

We analyze the impact of increased immigration on labor market outcomes of natives in Germany using a dataset of county level variables for the late 1908s. In order to construct more unified labor market regions we aggregate the 328 counties to 167 larger regions. We study two measures of...

Die Arbeitserlaubnis ist das wichtigste Instrument zur Kontrolle des Arbeitsmarktzugangs von ausländischen Immigranten. Die Erteilung einer allgemeinen Arbeitserlaubnis wird - unter Beachtung des Anwerbestopps - normalerweise nur dann vorgenommen, wenn kein Deutscher oder gleichberechtigter...
