Housing Yields

Abstract
We build a granular dataset of residential property yields using rental and sale listings from a major German real estate platform. With more than 1.5 million property-level rent-to-price ratios, we document a novel heterogeneity puzzle. About two-fifths of yield dispersion remains unexplained after controlling for extensive observable property characteristics and postal code-level time-varying factors using fixed effects. When we absorb finer neighborhood amenities through richer fixed effects, the unexplained share remains close to one-third. This evidence points to the importance of investors’ beliefs and preferences—rather than several alternative explanations we test—as sources of heterogeneity in risk premia.

Regional Deprivation, Individual Prospects, and Political Resentment

British Journal of Political Science,
forthcoming
Abstract
Regional economic conditions are well-established determinants of the geography of political resentment. However, regions are not homogeneous, and the mechanisms through which local economies affect individual political attitudes are unclear. We argue that feelings of relative deprivation are shaped by how personal prospects are tied to regional conditions, and that the interaction between subjective individual and regional deprivation affects perceptions of shared struggle and systemic unfairness. Through a large-scale survey experiment in Britain addressing geographical self-selection, we provide causal evidence that poor individuals in poor regions express political resentment, whereas in affluent regions the political attitudes of poor and wealthy individuals are indistinguishable. Our findings stress 1) the importance of egocentric mechanisms whereby local economies shape individual prospects; 2) the significance of subjective beliefs over objective information on deprivation; 3) the mobilization potential of highlighting regional deprivation by political entrepreneurs; 4) the relevance of place-based policies to mitigate political discontent.

EREI-Update: Rents remain high in Spanish cities
Pressure in the Spanish rental market made Prime Minister Sánchez call for early elections on October 5, to be held in late November 2026, possibly indicating that rental market pressure can turn into political pressure. The latest European Real Estate Index (EREI) by the Halle Institute for Economic Research (IWH) confirms indeed that the average rent in Spanish metropolitan areas was 23% higher compared to rural areas in Spain. This city rental premium in Spain was thus significantly above the EU average of 17%.

IWH-Insolvenztrend: Mehr Firmenpleiten im September, aber leichter Rückgang im dritten Quartal
Wie das Leibniz-Institut für Wirtschaftsforschung Halle (IWH) in einer heute veröffentlichten Analyse feststellt, stieg die Zahl der Insolvenzen von Personen- und Kapitalgesellschaften in Deutschland im September wieder an. Im dritten Quartal 2026 ging die Zahl der Firmenpleiten gegenüber dem Vorquartal leicht zurück, blieb aber auf dem zweithöchsten Stand seit 2005. Zum Jahresende ist weitere Entspannung in Sicht.

East Germany also benefits from higher foreign demand – Implications of the Joint Economic Forecast Autumn 2026 and official regional data for the East German economy
In 2026, economic activity in East Germany is expected to grow significantly, though somewhat less strongly than in Germany as a whole. In the years ahead, the Halle Institute for Economic Research (IWH) forecasts only minor differences in growth rates between East and West Germany. The East German economy is expected to grow by 0.9% in the current year (Germany as a whole: 1.3%). Thereafter, output in East Germany is likely to expand at a pace broadly similar to that of Germany overall, rising by 0.9% in 2027 and by 0.4% in 2028.

Joint Economic Forecast Autumn 2026: Recovery under structural stress – fiscal policy on slippery ground
The German economy has been recovering since the end of 2025. This recovery, although stronger than expected in spring, remains modest. The leading economic research institutes expect GDP growth of 1.3% for the current year and 1.1% and 0.4% for the following two years, respectively. Compared with the spring forecast, the outlook for 2026 has been revised upward by 0.7 and that for 2027 by 0.2 percentage points. “The economy has developed more robustly than expected. However, the recovery rests on a narrow foundation, as high energy prices and structural problems continue to weigh on economic activity,” says Oliver Holtemöller, Head of Macroeconomic Forecasting at the Halle Institute for Economic Research (IWH). In the current quarter, low water levels are also temporarily dampening economic activity. The government deficit continues to increase, leading to a growing need for fiscal consolidation.

EREI-Update: Rents in Europe’s cities are 23% higher on average than in rural areas
The European Commission currently prepares the Affordable Housing Act to tackle widespread concerns about tight housing markets, for example voiced by the German Tenants' Federation (DMB) which blames rising rental cost as one main driver of a social crisis in Germany. The latest European Real Estate Index (EREI) by the Halle Institute for Economic Research (IWH) shows that rental prices in Germany rose indeed three times compared to the European average in August. Moreover, the rental premium in metropolitan areas vis-à-vis the average in non-metropolitan areas in eleven EU member states amounts to 23%.

Economic Outlook: German economy on a recovery path – Tailwinds from the global economy and fiscal policy
An increase in foreign demand has put the German economy on a recovery path in the first half of the year, despite higher energy prices. In the coming quarters, rising public investment is expected to support economic activity. According to the autumn forecast of the Halle Institute for Economic Research (IWH), gross domestic product (GDP) is projected to grow by 1.4% this year and by 0.8% in 2027. Economic recovery in eastern Germany is expected to be somewhat weaker. In June, the IWH economists had predicted growth of 0.9% for both this and the next year.

Launch of the European Real Estate Index (EREI): German housing prices continue to rise more slowly than in Europe
Growth in asking prices for German residential properties offered for sale has lagged the European EREI aggregate since spring 2025. This is shown by the new European Real Estate Index (EREI) presented today by the Halle Institute for Economic Research (IWH). This novel data service hinges on more than 43 million listings on online real estate platforms and provides monthly comparisons of residential asking prices and advertised rents across 1,154 European regions in near-real-time.
