Resolving the Missing Deflation Puzzle

Jesper Lindé, Mathias Trabandt
CEPR Discussion Papers 13690, 2019
publiziert in: Journal of Monetary Economics
Abstract
We propose a resolution of the missing deflation puzzle. Our resolution stresses the importance of nonlinearities in price- and wage-setting when the economy is exposed to large shocks. We show that a nonlinear macroeconomic model with real rigidities resolves the missing deflation puzzle, while a linearized version of the same underlying nonlinear model fails to do so. In addition, our nonlinear model reproduces the skewness of inflation and other macroeconomic variables observed in post-war U.S. data. All told, our results caution against the common practice of using linearized models to study inflation and output dynamics.

Konjunktur deutlich abgekühlt — politische Risiken hoch

Roland Döhrn, Oliver Holtemöller, Stefan Kooths, Claus Michelsen, Timo Wollmershäuser
Wirtschaftsdienst, Nr. 4, 2019
Abstract
Die Konjunktur in Deutschland hat sich seit Mitte des Jahres 2018 merklich abgekühlt. Der langjährige Aufschwung ist damit offenbar zu einem Ende gekommen. Die schwächere Dynamik wurde sowohl vom internationalen Umfeld als auch von branchenspezifischen Ereignissen ausgelöst. Die weltwirtschaftlichen Rahmenbedingungen haben sich — auch aufgrund politischer Risiken — eingetrübt, und das Verarbeitende Gewerbe hat mit Produktionshemmnissen zu kämpfen. Die deutsche Wirtschaft durchläuft nunmehr eine Abkühlungsphase, in der die gesamtwirtschaftliche Überauslastung zurückgeht.

Enforcement of Banking Regulation and the Cost of Borrowing

Yota D. Deli, Manthos D. Delis, Iftekhar Hasan, Liuling Liu
Journal of Banking and Finance, April 2019
Abstract
We show that borrowing firms benefit substantially from important enforcement actions issued on U.S. banks for safety and soundness reasons. Using hand-collected data on such actions from the main three U.S. regulators and syndicated loan deals over the years 1997–2014, we find that enforcement actions decrease the total cost of borrowing by approximately 22 basis points (or $4.6 million interest for the average loan). We attribute our finding to a competition-reputation effect that works over and above the lower risk of punished banks post-enforcement and survives in a number of sensitivity tests. We also find that this effect persists for approximately four years post-enforcement.

Konjunktur deutlich abgekühlt – Politische Risiken hoch: Gemeinschaftsdiagnose Frühjahr 2019

Dienstleistungsauftrag des Bundesministeriums für Wirtschaft und Energie, Nr. 1, 2019
Abstract
Die Konjunktur in Deutschland hat sich seit Mitte des Jahres 2018 merklich abgekühlt. Der langjährige Aufschwung ist damit offenbar zu einem Ende gekommen. Die schwächere Dynamik wurde sowohl vom internationalen Umfeld als auch von branchenspezifischen Ereignissen ausgelöst. Die weltwirtschaftlichen Rahmenbedingungen haben sich – auch aufgrund politischer Risiken – eingetrübt, und das Verarbeitende Gewerbe hat mit Produktionshemmnissen zu kämpfen. Die deutsche Wirtschaft durchläuft nunmehr eine Abkühlungsphase, in der die gesamtwirtschaftliche Überauslastung zurückgeht. Die Institute erwarten für das Jahr 2019 nur noch ein Wirtschaftswachstum von 0,8% und damit mehr als einen Prozentpunkt weniger als noch im Herbst 2018. Die Gefahr einer ausgeprägten Rezession mit negativen Veränderungsraten des Bruttoinlandsprodukts über mehrere Quartale halten die Institute jedoch bislang für gering, jedenfalls solange sich die politischen Risiken nicht weiter zuspitzen. Für das Jahr 2020 bestätigen die Institute ihre Prognose aus dem vergangenen Herbst: Das Bruttoinlandsprodukt dürfte im Jahr 2020 um 1,8% zunehmen.

The Income Elasticity of Mortgage Loan Demand

Manthos D. Delis, Iftekhar Hasan, Chris Tsoumas
Financial Markets, Institutions and Instruments, Special Issue: 2016 Portsmouth – Fordham Conferenc 2019
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.

Private Equity and Financial Fragility During the Crisis

Shai B. Bernstein, Josh Lerner, Filippo Mezzanotti
Review of Financial Studies, Nr. 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

Natalie Packham, Fabian Wöbbeking
Journal of Banking and Finance, April 2019
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, Nr. 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.

National Culture and Risk-taking: Evidence from the Insurance Industry

Chrysovalantis Gaganis, Iftekhar Hasan, Panagiota Papadimitri, Menelaos Tasiou
Journal of Business Research, April 2019
Abstract
The gravity of insurance within the financial sector is constantly increasing. Reasonably, after the events of the recent financial turmoil, the domain of research that examines the factors driving the risk-taking of this industry has been signified. The purpose of the present study is to investigate the interplay between national culture and risk of insurance firms. We quantify the cultural overtones, measuring national culture considering the dimensions outlined by the Hofstede model and risk-taking using the ‘Z-score’. In a sample consisting of 801 life and non-life insurance firms operating across 42 countries over the period 2007–2016, we find a strong and significant relationship among insurance firms' risk-taking and cultural characteristics, such as individualism, uncertainty avoidance and power distance. Results remain robust to a variety of firm and country-specific controls, alternative measures of risk, sample specifications and tests designed to alleviate endogeneity.

Do Smarter Teachers Make Smarter Students?

Eric A. Hanushek, Marc Piopiunik, Simon Wiederhold
Education Next, Nr. 2, 2019
Abstract

Student achievement varies widely across developed countries, but the source of these differences is not well understood. One obvious candidate, and a major focus of research and policy discussions both in the United States and abroad, is teacher quality.
