Protest! Die Rolle kultureller Prägung im Volkswagenskandal
Felix Noth, Lena Tonzer
Wirtschaft im Wandel,
Nr. 3,
2020
Abstract
Die Aufdeckung manipulierter Abgaswerte bei Dieselautos des Herstellers Volkswagen (VW) durch die amerikanischen Behörden im Jahr 2015 brachte einen der größten Unternehmensskandale Deutschlands zutage. Dieser Skandal blieb nicht ohne Konsequenzen. Martin Winterkorn trat von seinem Amt als Vorstandsvorsitzender und Michael Horn als Chef von Volkswagen in den USA zurück. Viele VW-Kunden klagten gegen den Konzern, und in deutschen Großstädten wurde über Dieselfahrverbote diskutiert. Doch gab es auch eine Reaktion auf Konsumentenseite, also seitens der Autokäufer? Und wenn ja, spielen hier gesellschaftskulturelle Unterschiede wie zum Beispiel religiöse Prägung eine Rolle? Diesen Fragen geht ein im letzten Jahr erschienenes Arbeitspapier des IWH nach. Die empirische Analyse beschäftigt sich mit der Frage, ob Konsumenten nach dem VW-Skandal ihr Kaufverhalten stärker anpassen, wenn das gesellschaftliche Umfeld protestantisch geprägt ist. In der wissenschaftlichen Literatur zeigt sich, dass Protestanten mehr Wert auf eine Überwachung und Durchsetzung von Regeln legen, weshalb die Autoren von dieser Religionsgruppe eine ausgeprägtere Reaktion auf den VW-Skandal erwarten. Das Hauptergebnis der Studie legt dann genau diesen Schluss nahe: In den deutschen Regionen, in denen die Mehrheit der Bevölkerung dem protestantischen Glauben angehört, kam es zu signifikant höheren Rückgängen bei VW-Neuzulassungen infolge des VW-Skandals. Der Effekt ist umso stärker, je länger die Region durch protestantische Werte geprägt ist. Offenbar können bestimmte gesellschaftskulturelle Ausprägungen wie Religion und deren Normen ein Korrektiv für Verfehlungen von Unternehmen darstellen und somit verzögerte oder ausbleibende Maßnahmen von Politikern und Regulierern zum Teil ersetzen.

Banking Deregulation and Household Consumption of Durables
H. Evren Damar, Ian Lange, Caitlin McKennie, Mirko Moro
Abstract
We exploit the spatial and temporal variation of the staggered introduction of interstate banking deregulation across the U.S. to study the relationship between credit constraints and consumption of durables. Using the American Housing Survey from 1981 to 1993, we link the timing of these reforms with evidence of a credit expansion and household responses on many margins. We find robust evidence that households are more likely to purchase new appliances and invest in home renovations and modifications after the deregulation. These durable goods allowed households to consume less electricity and spend less time in domestic activities after the reforms.

Dynamic Equity Slope
Matthijs Breugem, Stefano Colonnello, Roberto Marfè, Francesca Zucchi
Working Papers University of Venice "Ca' Foscari",
Nr. 21,
2020
Abstract
The term structure of equity and its cyclicality are key to understand the risks drivingequilibrium asset prices. We propose a general equilibrium model that jointly explainsfour important features of the term structure of equity: (i) a negative unconditionalterm premium, (ii) countercyclical term premia, (iii) procyclical equity yields, and (iv)premia to value and growth claims respectively increasing and decreasing with thehorizon. The economic mechanism hinges on the interaction between heteroskedasticlong-run growth — which helps price long-term cash flows and leads to countercyclicalrisk premia — and homoskedastic short-term shocks in the presence of limited marketparticipation — which produce sizeable risk premia to short-term cash flows. The slopedynamics hold irrespective of the sign of its unconditional average. We provide empirical support to our model assumptions and predictions.

Identifying Cooperation for Innovation ― A Comparison of Data Sources
Michael Fritsch, Mirko Titze, Matthias Piontek
Industry and Innovation,
Nr. 6,
2020
Abstract
The value of social network analysis is critically dependent on the comprehensive and reliable identification of actors and their relationships. We compare regional knowledge networks based on different types of data sources, namely, co-patents, co-publications, and publicly subsidized collaborative R&D projects. Moreover, by combining these three data sources, we construct a multilayer network that provides a comprehensive picture of intraregional interactions. By comparing the networks based on the data sources, we address the problems of coverage and selection bias. We observe that using only one data source leads to a severe underestimation of regional knowledge interactions, especially those of private sector firms and independent researchers.

Structural Stability of the Research & Development Sector in European Economies Despite the Economic Crisis
Jutta Günther, Maria Kristalova, Udo Ludwig
Journal of Evolutionary Economics,
Nr. 5,
2019
Abstract
When an external shock such as the economic crisis in 2008/2009 occurs, the interconnectedness of sectors can be affected. This paper investigates whether the R&D sector experienced changes in its sectoral integration through the recession. Based on an input-output analysis, it can be shown that the linkages of the R&D sector with other sectors remain stable. In some countries, the inter-sectoral integration becomes even stronger. Policy makers can be encouraged to use public R&D spending as a means of fiscal policy against an economic crisis.

Pricing Sin Stocks: Ethical Preference vs. Risk Aversion
Stefano Colonnello, Giuliano Curatola, Alessandro Gioffré
European Economic Review,
2019
Abstract
We develop an ethical preference-based model that reproduces the average return and volatility spread between sin and non-sin stocks. Our investors do not necessarily boycott sin companies. Rather, they are open to invest in any company while trading off dividends against ethicalness. When dividends and ethicalness are complementary goods and investors are sufficiently risk averse, the model predicts that the dividend share of sin companies exhibits a positive relation with the future return and volatility spreads. An empirical analysis supports the model’s predictions. Taken together, our results point to the importance of ethical preferences for investors’ portfolio choices and asset prices.

The Income Elasticity of Mortgage Loan Demand
Manthos D. Delis, Iftekhar Hasan, Chris Tsoumas
Financial Markets, Institutions & 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.
