Deposit Competition and Mortgage Securitization
Danny McGowan, Huyen Nguyen, Klaus Schaeck
Journal of Money, Credit and Banking,

Abstract
We study how deposit competition affects a bank's decision to securitize mortgages. Exploiting the state-specific removal of deposit market caps across the U.S. as a source of competition, we find a 7.1 percentage point increase in the probability that banks securitize mortgage loans. This result is driven by an 11 basis point increase in deposit costs and corresponding reductions in banks' deposit holdings. Our results are strongest among banks that rely more on deposit funding. These findings highlight a hitherto undocumented and unintended regulatory cause that motivates banks to adopt the originate-to-distribute model.

No. 3,
2025
Abstract
On September 25th, financial economists from all over the world travelled for the 11th time to Halle (Saale) to attend the annual FIN-FIRE Workshop at IWH. During two days, authors of ten papers covered a comprehensive overview of contemporary issues that pose potential challenges to the financial system, including data privacy in mortgage markets, climate risks in bond markets, synthetic risk transfers, the effects of geopolitical risks for lending, as well as granular perspectives on the transmission of monetary policy. An intense exchange of thoughts between authors, discussants, and the audience yielded genuinely new insights into the resilience and fragility of financial systems.

A Helping Hand, but not a Lift. EU Cohesion Policy and Regional Development
Eva Dettmann, Sarah Fritz
IWH Discussion Papers,
No. 18,
2025
Abstract
This study provides new evidence on the impact of the EU Cohesion Policy on income growth in less developed regions. Our panel includes data from all European regions for the years 1989-2020. Using a fuzzy Regression Discontinuity Design, we model treatment dynamics by applying a random effects estimator. Based on digitized historical data, we precisely replicate the policy rule and correctly classify the regions’ eligibility status. Results show that the policy has a moderate positive effect on GDP per capita growth in the targeted regions.

Fiscal policy will stimulate the East German economy next year – Economic Forecast Fall 2025 for the East German economy
In 2025, the economy in East Germany, as in Germany as a whole, is likely to do little more than stagnate. In the coming year, fiscal policy measures will stimulate the economy, but their effects are likely to be somewhat weaker than in Germany as a whole. The Halle Institute for Economic Research (IWH) expects the expansion rate of the East German economy in 2025 to be at 0.3%, slightly higher than that of Germany as a whole (0.2%). In both following years, it will rise to 1.1% and 1.2% respectively, which is slightly less than in the west.

Recovery on shaky ground – tariffs dampen growth, but a change in fiscal policy is on the way
In late summer 2025, it is still unclear whether the German economy is on the road to recovery, as it has to cope with the dampening effect of higher US tariffs in the second half of the year. It is not until 2026 that fiscal policy stimulus measures, combined with low key interest rates, will probably lead to an economic upturn. According to the autumn forecast of the Halle Institute for Economic Research (IWH), production is then expected to increase by 0.8%, following 0.2% in 2025. Similar rates of expansion are also expected for East Germany. In June, the IWH economists were forecasting growth of 1.1% for 2026 and 0.4% for the current year.

‘And Forgive Us Our Debts’: Christian Moralities and Over-indebtedness
Iftekhar Hasan, Konstantin Kiesel, Felix Noth
Journal of Financial Research,
Fall
2025
Abstract
This paper analyses whether Christian moralities and rules formed differently by Catholics and Protestants impact the likelihood of households to become overindebted. We find that over-indebtedness is lower in regions in which Catholics outweigh Protestants, indicating that Catholics‘ forgiveness culture and a stricter enforcement of rules by Protestants serve as explanations for our results. Our results provide evidence that religion affects the financial situations of individuals and show that even 500 years after the split between Catholics and Protestants, the differences in the mind-sets of both denominations play an important role for situations of severe financial conditions.

College Application Choices in a Repeated Deferred Acceptance (DA) Setting: Empirical Evidence from Croatia
Dejan Kovač, Christopher Neilson, Johanna Raith
IWH Discussion Papers,
No. 9,
2025
Abstract
How do beliefs on admission probability influence application choices? In this study, we empirically investigate whether and how admission probability is reflected in application choices in a centralized admission system. We exploit a novel setting of a dynamic deferred acceptance mechanism as employed in Croatia with hourly information updates and simultaneous application choices. This setting allows us to explore within-applicant strategic adjustments as a reaction to changing signals on admission probability. We show in an RDD analysis that applicants react to negative signals on admission probability with an increased propensity to adjust their application choices by 11-23%. Additionally, we show how application strategies evolve over time, while applicants learn about their admission probability. The group most-at-risk to remain unmatched improves their application choices by applying to programs with a higher admission probability towards the application deadline. Yet, we also identify a popular and potentially harmful strategy of applying to safer programs before applying to more risky “reach” programs. About a quarter of applicants have the potential to improve their application choices by resorting their application choices.

Economic recovery in Germany – but structural problems and US trade policy weigh on the economy
The German economy has picked up somewhat in the first half of 2025. This was helped by the temporary increase in demand from the US in anticipation of higher tariffs. If the US does not escalate its trade conflicts further, production in Germany according to the summer forecast of the Halle Institute for Economic Research (IWH) is likely to increase a bit (by 0.4%) in 2025, after two years of decline. In March, the IWH economists were forecasting growth of 0.1% for the current year. Growth of 1.1% is forecast for the year 2026. Similar expansion rates are to be expected for East Germany.

The Halle Institute for Economic Research (IWH) expects stagnation for East Germany in 2025 and growth of 1.1% in 2026. According to the IWH forecast, the unemployment rate is expected to be 7.8% in both 2025 and 2026, after 7.5% in 2024.
