Abstract
Over the last decade, German housing prices have increased unprecedentedly. Drawing on quality-adjusted housing price data at the district level, we document large and increasing regional disparities: Growth rates were higher in 1) the largest seven cities, 2) districts located in the south, and 3) districts with higher initial price levels. Indications of price bubbles are concentrated in the largest cities and in the purchasing market. Prices seem to be driven by the demand side: Increasing population density, higher shares of academically educated employees and increasing purchasing power explain our findings, while supply remained relatively constrained in the short term.

Non-Standard Errors

Abstract
In statistics, samples are drawn from a population in a datagenerating process (DGP). Standard errors measure the uncertainty in sample estimates of population parameters. In science, evidence is generated to test hypotheses in an evidencegenerating process (EGP). We claim that EGP variation across researchers adds uncertainty: non-standard errors. To study them, we let 164 teams test six hypotheses on the same sample. We find that non-standard errors are sizeable, on par with standard errors. Their size (i) co-varies only weakly with team merits, reproducibility, or peer rating, (ii) declines significantly after peer-feedback, and (iii) is underestimated by participants.

COVID-19 Financial Aid and Productivity: Has Support Been Well Spent?

Abstract
Most European Union countries have made good progress with vaccinating their populations against COVID-19 and are now seeing a rebound in economic activity. While the scarring effects of the crisis and the long-term implications of the pandemic are only partially understood, the effects of support given to firms can be evaluated in order to help plan the removal of crisis support. An analysis of France, Germany and Italy shows the potential for ‘cleansing effects’ in that it was the least-productive firms that have been affected most by the crisis. While support was generally not targeted at protecting good firms only, financial support went by and large to those with the capacity to survive and succeed. Labour schemes have been effective in protecting employment.

Production bottlenecks delay recovery
The German recovery made good progress over the summer 2021. However, bottlenecks in sea transport and the production of intermediate goods are weighing on world trade. The rise in raw material prices has prompted inflation rates to spike, and an increase in new infections is clouding the outlook again. A weak final quarter is therefore to be expected. The Halle Institute for Economic Research (IWH) forecasts that German gross domestic product (GDP) will increase by 2.2% in 2021 and 3.6% in 2022 (East Germany: 1.8% and 2.8%).

Aktuelle Trends: Trendmäßiger Anstieg der Sterbefälle in Deutschland – Altersstruktur bei der Interpretation der Sterblichkeit berücksichtigen

No. 1,

Abstract
In Deutschland steigt aufgrund der Altersstruktur die Anzahl der jährlichen Sterbefälle. Ein einfacher Vergleich der aktuellen Sterbefälle mit dem Durchschnitt der Vorjahre ist daher nicht geeignet, um die Übersterblichkeit während der Pandemie zu beurteilen.

During Corona, households are saving more – not for fear of unemployment but for lack of spending opportunities
During the Corona crisis, European households increased their savings dramatically. According to an analysis carried out by the Halle Institute for Economic Research (IWH), the increase in savings is largely due to the inability of households to consume in the face of government lockdown measures, rather than other factors such as economic uncertainty. IWH President Reint Gropp therefore sees potential for a significant catch-up effect in consumption as soon as the lockdown is lifted.
