Regulating Zombie Mortgages

Review of Finance,

Abstract
Using the adoption of Zombie Property Laws (ZL) across several US states, we show that requiring lenders to maintain properties in the foreclosure process affects mortgage lending decisions and standards. Difference-in-differences estimations using a state border design show that ZL incentivizes lenders to screen mortgage applications more carefully: they deny more applications and impose higher interest rates on originated loans, especially risky loans. In turn, these loans exhibit higher ex post performance. ZL also affects lender behavior after borrowers become distressed, causing them to strategically keep delinquent mortgages alive. Our findings inform the debate on policy responses to foreclosure crises.

Mixing QE and Interest Rate Policies at the Effective Lower Bound: Micro Evidence from the Euro Area
Christian Bittner, Alexander Rodnyansky, Farzad Saidi, Yannick Timmer
Review of Finance,
forthcoming
Abstract
We study the interaction of expansionary rate-based monetary policy and quantitative easing, despite their concurrent implementation, by exploiting heterogeneous banks and the introduction of negative monetary-policy rates in a fragmented euro area. Quantitative easing increases credit supply less, translating into weaker employment growth, when banks’ funding costs do not decrease. Using administrative data from Germany, we uncover that among banks selling their securities, central-bank reserves remain disproportionately with high-deposit banks that are constrained due to sticky customer deposits at the zero lower bound. Affected German banks lend relatively less to firms while increasing their interbank exposure in the euro area.

Is There an Information Channel of Monetary Policy?
Oliver Holtemöller, Alexander Kriwoluzky, Boreum Kwak
Oxford Bulletin of Economics and Statistics,
forthcoming
Abstract
Exploiting the heteroskedasticity of the changes in short-term and long-term interest rates and exchange rates around the FOMC announcement, we identify three structural monetary policy shocks. We eliminate the predictable part of the shocks and study their effects on financial variables and macro variables. The first shock resembles a conventional monetary policy shock, and the second resembles an unconventional monetary shock. The third shock leads to an increase in interest rates, stock prices, industrial production, consumer prices, and commodity prices. At the same time, the excess bond premium and uncertainty decrease, and the U.S. dollar depreciates. Therefore, this third shock combines all the characteristics of a central bank information shock.

Sticky Prices or Sticky Wages? An Equivalence Result
Florin Bilbiie, Mathias Trabandt
Review of Economics and Statistics,
forthcoming
Abstract
We show an equivalence result in the representative-agent New-Keynesian model after demand, wage-markup and correlated price-markup and TFP shocks: assuming sticky prices and flexible wages yields identical allocations for GDP, consumption, labor, inflation and interest rates to the opposite case—flexible prices and sticky wages. This equivalence arises with identical price and wage Phillips-curve slopes and generalizes to any slopes' pair whose sum and product are identical. Equilibrium profits and wages are, however, substantially different; equivalence breaks when these factor-distributional implications matter for aggregate allocations, e.g. in New-Keynesian models with heterogeneous agents, endogenous firm entry, and non-constant returns to scale.

Safety in Unemployment and Risky Experimentation of Young Firms
Renato Faccini, Seho Kim, Javier Miranda
IWH Discussion Papers,
No. 15,
2026
Abstract
We develop a theory in which a lower cost of job loss reduces the compensating wage premium workers require to join risky young firms. Lower labor costs encourage high-upside experimentation and raise productivity. Because experimentation is not directly observable, we exploit its life-cycle structure: experimentation risk is concentrated among young firms and resolved as firms mature. Using Danish matched employer-employee data and labor-market variation, we show that higher job-finding rates are associated with a lower young-mature wage differential. A randomized survey experiment supports the mechanism: worsening unemployment prospects increases the premium workers require to accept employment at higher-failure-risk young firms.

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.

Konjunktur aktuell: Deutsche Konjunktur belebt sich – Rückenwind von Weltwirtschaft und Finanzpolitik
Konjunktur aktuell,
No. 3,
2026
Abstract
Die deutsche Wirtschaft befindet sich trotz höherer Energiepreise und anhaltender Risiken durch den Golfkonflikt auf Erholungskurs. Eine steigende Auslandsnachfrage und zusätzliche staatliche Investitionen stützen die Konjunktur, während die Beschäftigung insbesondere im Verarbeitenden Gewerbe weiter rückläufig ist. Die Produktion dürfte in diesem Jahr um 1,4% und im kommenden Jahr um 0,8% zunehmen; in Ostdeutschland fällt die wirtschaftliche Erholung etwas schwächer aus.

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.

Economic Outlook: Between Energy Crisis and AI Boom
Until the outbreak of the energy crisis, the German economy was on a path to recovery. Now the recovery will only continue over the course of 2026 if the Gulf conflict eases and energy prices do not rise further. This assumption underlies the present summer forecast of the Halle Institute for Economic Research (IWH). In that case, German output is expected to increase by 0.9% for this year and for 2027. Growth rates in East Germany will be similar. In March, the IWH economists had predicted growth of 0.7% for 2026 and 1% for the next year.

Konjunktur aktuell: Zwischen Energiekrise und KI-Boom
Konjunktur aktuell,
No. 2,
2026
Abstract
Die deutsche Wirtschaft steht infolge der Energiekrise und des anhaltenden Golfkonflikts vor einer unsicheren Erholung. Steigende Kosten und eine schwächere Beschäftigungsentwicklung belasten die Konjunktur, während die Finanzpolitik stützend wirkt. Unter der Annahme stabiler Energiepreise dürfte die Produktion in diesem und im kommenden Jahr um jeweils 0,9% zunehmen; ähnliche Expansionsraten sind auch für Ostdeutschland zu erwarten.
