Immigration, Tax Progressivity, and Support for Redistribution

Abstract
How does immigration affect support for redistribution? While most research focuses on overall tax and spending levels, we investigate how immigration influences preferences conditional on tax structures. Using two original survey experiments in the UK, we find that low- and middle-income respondents are more likely to support redistribution to immigrants under progressive systems shielding them from fiscal costs, but oppose redistribution when immigrants are identified as beneficiaries and the tax structure increases their fiscal burden. In contrast, high-income respondents' preferences are largely unaffected by either tax structure or immigrant inclusion. These findings suggest that progressive taxation (1) is a viable revenue-generating strategy without provoking major political backlash; (2) reduces native resistance to immigrant welfare inclusion; (3) helps explain puzzling variation in immigration's effects on welfare attitudes; and (4) clarifies why low- and middle-income groups sometimes reject generous welfare programs despite standing to benefit. Our results highlight the importance of institutional design in shaping how economic self-interest and immigration concerns interact.

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%.

IWH-Insolvenztrend: Firmenpleiten gehen im August zurück, bleiben aber auf hohem Niveau
Wie das Leibniz-Institut für Wirtschaftsforschung Halle (IWH) in einer heute veröffentlichten Analyse feststellt, ist die Zahl der Insolvenzen von Personen- und Kapitalgesellschaften in Deutschland im August gesunken. Die Zahl der betroffenen Arbeitsplätze stieg dagegen an. Die Frühindikatoren deuten darauf hin, dass die Insolvenzzahlen in den kommenden Monaten wieder sehr hoch ausfallen dürften.

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.

Sachsen-Anhalt vor der Wahl: Ausländerfeindliche Politik könnte Arbeitskräftemangel deutlich verschärfen
Sollte die AfD nach der Landtagswahl in Sachsen-Anhalt regieren, könnte ihre Politik die Wirtschaft in dem Bundesland erheblich beeinträchtigen. Nach Schätzungen des Leibniz-Instituts für Wirtschaftsforschung Halle (IWH) würden Sachsen-Anhalt infolge eines fremdenfeindlichen Klimas in der nächsten Legislaturperiode Tausende Arbeitskräfte und eine Wertschöpfung von bis zu 3,2 Milliarden Euro entgehen.

Out of Sight, out of Mind: Divestments and the Global Reallocation of Pollutive Assets

Abstract
We document a global reallocation of pollutive assets as a response to investor pressure: large firms facing increased investor pressure divest foreign-located pollutive assets to firms that are less in the limelight. There is no evidence of increased engagement in any other emission reduction activities. We estimate that 369 million metric tons (mt) of CO2e are reallocated via divestments in the post-Paris Agreement period. Our results indicate that investor pressure to decarbonize reshapes the global conglomerate structure of large firms.

Institutional Blockholders and Corporate Innovation

Abstract
The previous literature finds a positive effect of institutional (relative to other investors’) ownership on firms’ innovation output . We study the impact of increases in the concentration of institutional investors’ ownership on firms’ decisions to invest in innovation and their innovation output. By reducing short-term earnings pressure, concentrated institutional investors’ ownership increases managers’ incentives to invest in R&D. However, it decreases firms’ acquisitions of external innovation due to empire-building and dilution concerns. Overall, firms’ future patents and citations decrease. Our results indicate that the previously found positive effect of institutional investors on innovation declines as the ownership of these investors becomes more concentrated. Despite that, we find that blockholder institutional ownership increases firm value. Hence, large institutional investors take measures to preserve the value of their ownership interests, even if they result in reduced innovation.
