Linking Brain Age Gap to Mental and Physical Health in the Berlin Aging Study II

From a biological perspective, humans differ in the speed they age, and this may manifest in both mental and physical health disparities. The discrepancy between an individual’s biological and chronological age of the brain (“brain age gap”) can be assessed by applying machine learning techniques to Magnetic Resonance Imaging (MRI) data. Here, we examined the links between brain age gap and a broad ...

Lessons from an Aborted Second-Generation Rent Control in Catalonia

This study investigates the effects of short-lived rent control regulations introduced in Catalonia in September 2020 and revoked in March 2022. Using the microdata of the largest Spanish housing advertisement portal idealista between January 2017 and May 2022, we analyze the dynamics of prices and supply for dwellings offered for rent and for sale. We also examine separately the rental and sales markets. ...

Geodata in Labor Market Research: Trends, Potentials and Perspectives

This article shows the potentials of georeferenced data for labor market research. We review developments in the literature and highlight areas that can benefit from exploiting georeferenced data. Moreover, we share our experiences in geocoding administrative employment data including wage and socioeconomic information of almost the entire German workforce between 2000 and 2017. To make the data easily ...

The Rise and Fall of Social Housing? Housing Decommodification in Long-run Comparison

The comparative study of housing decommodification lags behind classical welfare state research, while housing research itself is rich in homeownership studies but lacks comparative accounts of private and social rentals due to missing comparative data. Building on existing works and various primary sources, this study presents a new collection of up to forty-eight countries’ social housing shares ...

House Price Expectations

This study examines short-, medium-, and long-run price expectations in housing markets. We derive and test six hypothesis about the incidence, formation, and relevance of price expectations. To do so, we use data from a tailored household survey, past sale and rental offerings, satellites, and from an information RCT. As novel findings, we show that price expectations exhibit mean reversion in the ...

Forward to the Past: Short-Term Effects of the Rent Freeze in Berlin

In 2020, Berlin introduced a rigorous rent-control policy responding to soaring rents by setting a cap on rental prices: the Mietendeckel (rent freeze). The policy was revoked one year later by the German Constitutional Court. Although successful in reducing rents during its duration, the consequences for Berlin’s rental market and adjacent municipalities are not clear. In this paper we evaluate the ...

Agglomeration or Market Access? The Defining Factors of Firms' Location Choice

As research indicates a gap between complex scientific measures of accessibility and simpler proxies used by firms, this paper analyses the impact of several market access indicators on the location decision of firms. It compares the role of inter- and intra-industry agglomeration as proxies of access with a newly developed gravity-based indicator incorporating transport distances and industry relations. ...

Forward to the Past: Short-Term Effects of the Rent Freeze in Berlin

In 2020, Berlin introduced a rigorous rent-control policy responding to soaring prices by capping rents: the Mietendeckel (rent freeze). The German Constitutional Court revoked the policy only one year later. Although successful in lowering rents during its duration, the consequences for Berlin’s rental market and close-by markets are per se not clear. This article evaluates the short-term causal supply-side ...

The Long-Run Effects of Immigration: Evidence across a Barrier to Refugee Settlement

After the end of World War II in 1945, millions of refugees arrived in what in 1949 became the Federal Republic of Germany. We examine their effect on today’s productivity, wages, income, rents, education, and population density at the municipality level. Our identification strategy is based on a spatial discontinuity in refugee settlement at the border between the French and US occupation zones in ...
