Abstract
One explanation for the emergence of the housing market bubble and the subprime crisis is that increases in individuals’ income led to higher increases in the amount of mortgage loans demanded, especially for the middle class. This hypothesis translates to an increase in the income elasticity of mortgage loan demand before 2007. Using applicant‐level data, we test this hypothesis and find that the income elasticity of mortgage loan demand in fact declines in the years before 2007, especially for the mid‐ and lower‐middle income groups. Our finding implies that increases in house prices were not matched by increases in loan applicants’ income.

Bank profitability increases after eliminating consolidation barriers
When two banks merge because political consolidation barriers are abolished, the combined entity is considerably more profitable and useful to the real economy. This is the headline result of an analysis of compulsory savings banks mergers carried out by the Halle Institute for Economic Research (IWH). The study yields important insights for the German and the European banking market.

Private Equity and Financial Fragility During the Crisis
Shai B. Bernstein, Josh Lerner, Filippo Mezzanotti
Review of Financial Studies,
No. 4,
2019
Abstract
Does private equity (PE) contribute to financial fragility during economic crises? The proliferation of poorly structured transactions during booms may increase the vulnerability of the economy to downturns. During the 2008 crisis, PE-backed companies decreased investments less than did their peers and experienced greater equity and debt inflows, higher asset growth, and increased market share. These effects are especially strong among financially constrained companies and those whose PE investors had more resources at the crisis onset. In a survey, PE firms report being active investors during the crisis and spending more time working with their portfolio companies.

A Factor-model Approach for Correlation Scenarios and Correlation Stress Testing

Journal of Banking and Finance,

Abstract
In 2012, JPMorgan accumulated a USD 6.2 billion loss on a credit derivatives portfolio, the so-called “London Whale”, partly as a consequence of de-correlations of non-perfectly correlated positions that were supposed to hedge each other. Motivated by this case, we devise a factor model for correlations that allows for scenario-based stress testing of correlations. We derive a number of analytical results related to a portfolio of homogeneous assets. Using the concept of Mahalanobis distance, we show how to identify adverse scenarios of correlation risk. In addition, we demonstrate how correlation and volatility stress tests can be combined. As an example, we apply the factor-model approach to the “London Whale” portfolio and determine the value-at-risk impact from correlation changes. Since our findings are particularly relevant for large portfolios, where even small correlation changes can have a large impact, a further application would be to stress test portfolios of central counterparties, which are of systemically relevant size.

Elevated Uncertainty during the Financial Crisis: Do Effects on Subjective Well-being Differ across European Countries?
Lena Tonzer
B.E. Journal of Economic Analysis and Policy,
No. 2,
2019
Abstract
This paper focuses on the effect of uncertainty as reflected by financial market variables on subjective well-being. The analysis is based on Eurobarometer surveys, covering 18 countries over the period 2000–2013. Individuals report lower levels of life satisfaction in times of higher uncertainty approximated by stock market volatility. This effect is heterogeneous across respondents: the probability of being unsatisfied is higher for respondents who are older, unemployed, less educated, and live in one of the GIIPS countries of the Euro area. Furthermore, higher uncertainty in combination with a financial crisis increases the probability of reporting low values of life satisfaction.

Monetary Policy Communication: Frameworks and Market Impact

forthcoming
Abstract
Bond markets are an important conduit of monetary policy signals to the economy. Reforms that improve the functioning of bond markets will hence facilitate macroeconomic management effectiveness. Here communication plays an increasingly important role. Good monetary policy communication is not only important to improve the effectiveness of monetary policy in the first place, but by reducing uncertainty it makes bond markets more attractive for investors, further improving monetary transmission.

Konjunktur aktuell: Deutsche Konjunktur nimmt nur langsam wieder Fahrt auf
Konjunktur aktuell,
No. 1,
2019
Abstract
Im Winterhalbjahr 2018/2019 hat sich die Weltkonjunktur deutlich abgekühlt. Allerdings divergiert die Lage zwischen den Regionen erheblich: Der Aufschwung in den USA hat nur wenig an Fahrt verloren, im Euroraum ist er dagegen zum Erliegen gekommen. Auch in China ist die Wirtschaft ins Stocken geraten. Ein wichtiger Grund für die weltwirtschaftliche Schwächephase dürfte in der Unsicherheit darüber liegen, welche Wendung die Streitigkeiten der US-Regierung mit China und der Europäischen Union nehmen. Zudem sind alle Fragen um den Brexit weiterhin offen. In Deutschland hat die gesamtwirtschaftliche Produktion im Schlussquartal 2018 stagniert, nach einem Rückgang um 0,2% im Quartal zuvor. Zur Produktionsschwäche trugen mit dem neuen Abgas-Prüfverfahren für Automobile und dem niedrigen Rheinwasser zwei Sondereffekte bei. Mehr ins Gewicht fällt, dass sich die Auslandsnachfrage, vor allem aus den EU-Partnerländern, verlangsamt hat. Die Unternehmen bauen dennoch weiter Beschäftigung auf. Offensichtlich wird die gegenwärtige Schwächephase vielfach als vorübergehend eingeschätzt. Die Folge ist allerdings ein deutlicher Anstieg der Lohnstückkosten. Auch für das erste Halbjahr 2019 ist wenig mehr als Stagnation zu erwarten. Dennoch dürfte der private Konsum robust expandieren, nicht zuletzt wegen steigender Reallöhne. Zudem stützen die niedrigen Zinsen und eine expansive Finanzpolitik. Das reale Bruttoinlandsprodukt liegt nach vorliegender Prognose im Jahr 2019 um 0,5% höher als im Vorjahr, im Jahr 2020 steigt die Rate auch wegen der höheren Arbeitstagezahl auf 2,0%. Die ostdeutsche Wirtschaft expandiert in diesem Jahr um 0,7% und im Jahr 2020 um 1,7%.

United Country – Three Decades After the Wall Came Down
Einzelveröffentlichungen,
2019
Abstract
Die Berliner Mauer als das Symbol der deutschen Teilung ist mittlerweile länger verschwunden als sie gestanden hat, doch die Unterschiede innerhalb des Landes sind auch nach drei Jahrzehnten noch sichtbar. Jüngste Forschungsergebnisse zeigen jedoch, dass die Bruchkante der wirtschaftlichen Entwicklung nicht immer ausschließlich entlang der ehemaligen innerdeutschen Grenze verläuft, sondern neben dem West-Ost-Gefälle auch Süd-Nord- oder Stadt-Land-Unterschiede zutage treten.

No-deal Brexit would hit the German labour market particularly hard
The United Kingdom leaving the European Union without a deal would have consequences for international trade and labour markets in many countries, including outside Europe. Calculations by the Halle Institute for Economic Research (IWH) indicate: More than 600,000 jobs may be affected worldwide, but nowhere as many as in Germany.
