Finanzmärkte

Die Abteilung „Finanzmärkte“ am IWH befasst sich mit dem institutionellen Wandel von Finanzsystemen in Europa. Die Forschung der Abteilung beschäftigt sich mit den Ursachen und Wirkungen der internationalen Tätigkeit von Banken und anderen Finanzintermediären, dem Zusammenhang zwischen Marktstrukturen im Bankensektor und gesamtwirtschaftlicher Stabilität, Ansteckungseffekten auf internationalen Finanzmärkten sowie der Rolle des Finanzsektors für die Realwirtschaft.

Hierbei spielen insbesondere Wechselwirkungen zwischen dem Finanzsektor und Wachstums- und Innovationsprozessen in der Realwirtschaft eine Rolle. Methodisch zielt die Forschung der Abteilung auf die integrierte Betrachtung von Anpassungen auf der Mikro- und Makroebene sowie die Evaluation wirtschaftspolitischer Maßnahmen zur Regulierung von Finanzmärkten.

The Real Effects of Universal Bank : Does Access to the Public Debt Market Matter?

Stefano Colonnello

in: Journal of Financial Services Research, im Erscheinen

Abstract

I analyze the impact of the formation of universal banks on corporate investment by looking at the gradual dismantling of the Glass-Steagall Act’s separation between commercial and investment banking. Using a sample of US firms and their relationship banks, I show that firms curtail debt issuance and investment after positive shocks to the underwriting capacity of their main bank. This result is driven by unrated firms and is strongest immediately after a shock. These findings suggest that universal banks may pay more attention to large firms providing more underwriting opportunities while exacerbating financial constraints of opaque firms, in line with a shift to a banking model based on transactional lending.

What drives the Commodity-Sovereign-Risk-Dependence in Emerging Market Economies?

Stefan Eichler Hannes Böhm Stefan Gießler

in: Journal of International Money and Finance, im Erscheinen

Abstract

Using daily data for 34 emerging markets in the period 1994–2016, we find robust evidence that higher export commodity prices are associated with lower sovereign default risk, as measured by lower EMBI spreads. The economic effect is especially pronounced for heavy commodity exporters. Examining the drivers, we find that, first, commodity dependence is higher for countries that export large volumes of commodities, whereas other portfolio characteristics like volatility or concentration are less important. Second, commodity-sovereign risk dependence increases in times of recessions and expansionary U.S. monetary policy. Third, the importance of raw material prices for sovereign financing can likely be mitigated if a country improves institutions and tax systems, attracts FDI inflows, invests in manufacturing, machinery and infrastructure, builds up reserve assets and opens capital and trade accounts. Fourth, the country’s government indebtedness or amount of received development assistance appear to be only of secondary importance for commodity dependence.

The Influence of Bondholder Concentration and Temporal Orientation on Investments in R&D

Pengfei Ye Jonathan O’Brien Christina Matz Carnes Iftekhar Hasan

in: Journal of Management, im Erscheinen

Abstract

Although innovation can be a critical source of competitive advantage, research has found that debt can erode management’s willingness to invest in R&D. In this article, we employ a stakeholder bargaining power perspective to argue that this effect is most pronounced when the firm’s bonds are concentrated in the hands of bond blockholders. Furthermore, we contend that the temporal orientation of bondholders influences this relationship. Specifically, while it is commonly assumed that bondholders have a limited temporal orientation that induces them to focus on short-term value appropriation, we argue that some bond blockholders adopt a long-term temporal orientation. This orientation, in turn, makes them more inclined to support long-term value creation for the firm in the form of enhanced investments in R&D. Moreover, while agency theory suggests that there is an inherent conflict of interest between shareholders and bondholders, our results suggest that the temporal orientation of investors (i.e., both shareholders and bondholders) matters much more than whether they invested in the firm’s equity or its debt.

Cultural Norms and Corporate Fraud: Evidence from the Volkswagen Scandal

Iftekhar Hasan Felix Noth Lena Tonzer

in: IWH-Diskussionspapiere, Nr. 24, 2020

Abstract

We investigate whether cultural norms shaped by religion drive consumer decisions after a corporate scandal. We exploit the notice of violation by the US Environmental Protection Agency in September 2015 accusing Volkswagen (VW) of using software to manipulate car emission values during test phases. We show that new registrations of VW cars decline significantly in German counties with a high share of Protestants following the VW scandal. Our findings document that the enforcement culture in Protestantism facilitates penalising corporate fraud. We corroborate this channel with a survey documenting that Protestants respond significantly different to fraud but not to environmental issues.

Competition, Cost Structure, and Labour Leverage: Evidence from the U.S. Airline Industry

Konstantin Wagner

in: IWH-Diskussionspapiere, Nr. 21, 2020

Abstract

I study the effect of increasing competition on financial performance through labour leverage. To capture competition, I exploit variation in product market contestability in the U.S. airline industry. First, I find that increasing competitive pressure leads to increasing labour leverage, proxied by labour share. This explains the decrease in operating profitability through labour rigidities. Second, by exploiting variation in human capital specificity, I show that contestability of product markets induces labour market contestability. Whereas affected firms might experience more stress through higher wages or loss of skilled human capital, more mobile employee groups benefit from competitions through higher labour shares.

Marginal Returns to Talent for Material Risk Takers in Banking

Moritz Stieglitz Konstantin Wagner

in: IWH-Diskussionspapiere, Nr. 20, 2020

Abstract

Economies of scale can explain compensation differentials over time, across firms of different size, different hierarchy-levels, and different industries. Consequently, the most talented individuals tend to match with the largest firms in industries where marginal returns to their talent are greatest. We explore a new dimension of this size-pay nexus by showing that marginal returns also differ across activities within firms and industries. Using hand-collected data on managers in European banks well below the level of executive directors, we find that the size-pay nexus is strongest for investment banking business units and for banks with a market-based business model. Thus, managerial compensation is most sensitive to size increases for activities that can easily be scaled up.

Cultural Resilience and Economic Recovery: Evidence from Hurricane Katrina

Iftekhar Hasan Stefano Manfredonia Felix Noth

in: IWH-Diskussionspapiere, Nr. 16, 2020

Abstract

This paper investigates the critical role of culture for economic recovery after natural disasters. Using Hurricane Katrina as our laboratory, we find a significant adverse treatment effect for plant-level productivity. However, local religious adherence and larger shares of ancestors with disaster experiences mutually mitigate this detrimental effect from the disaster. Religious adherence further dampens anxiety after Hurricane Katrina, which potentially spur economic recovery. We also detect this effect on the aggregate county level. More religious counties recover faster in terms of population, new establishments, and GDP.

Dynamic Equity Slope

Matthijs Breugem Stefano Colonnello Roberto Marfè Francesca Zucchi

in: 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 empir-ical support to our model assumptions and predictions.
