Real and Financial Innovation
This research group contributes to the scientific literature in three main ways. First, it provides new ways to identify shocks to the financial sector in financial systems and analyses how these shocks affect intermediaries with regard to risk taking (stability), efficiency (productivity) and the market structure in banking markets in general. Second, the identified external shocks are central to measure effects that financial intermediaries have on the real sector of financial systems. Because financial intermediaries play a special role in financial systems and are subject to many regulations, it is very important to understand how, e.g., risk taking incentives or different competition structures in banking markets affect real sector outcome like sales, GDP growth or employment. Third, the group focuses on the effects of foreign banks in financial systems and specifically how shocks to these banks (e.g., via their holding companies during the recent financial crisis) affect activities (e.g., lending) in the host countries.

Relationship Lenders and Unorthodox Monetary Policy: Investment, Employment, and Resource Reallocation Effects
We combine a number of unique and proprietary data sources to measure the impact of relationship lenders and unconventional monetary policy during and after the European sovereign debt crisis on the real economy. Establishing systematic links between different research data centers (Forschungsdatenzentren, FDZ) and central banks with detailed micro-level information on both financial and real activity is the stand-alone proposition of our proposal. The main objective is to permit the identification of causal effects, or their absence, regarding which policies were conducive to mitigate financial shocks and stimulate real economic activities, such as employment, investment, or the closure of plants.

When Arm’s Length is too Far: Relationship Banking over the Credit Cycle
in: Journal of Financial Economics, No. 1, 2018
We conduct face-to-face interviews with bank CEOs to classify 397 banks across 21 countries as either relationship or transaction lenders. We then use the geographic coordinates of these banks’ branches and of 14,100 businesses to analyze how the lending techniques of banks in the vicinity of firms are related to credit constraints at two contrasting points of the credit cycle. We find that while relationship lending is not associated with credit constraints during a credit boom, it alleviates such constraints during a downturn. This positive role of relationship lending is stronger for small and opaque firms and in regions with a more severe economic downturn. Moreover, our evidence suggests that relationship lending mitigates the impact of a downturn on firm growth and does not constitute evergreening of loans.
Politically Connected Firms in Poland and Their Access to Bank Financing
in: Communist and Post-Communist Studies, No. 4, 2017
This paper characterizes politically connected firms and their access to bank financing. We determine that the relationship between political connections and access to long-term bank loans is weaker in Poland than in other emerging economies. The most probable explanation for this result is related to the instability of the political climate in Poland. We find that only certain kinds of political connections, such as recent connections, positively influenced access to bank financing during the sample period from 2001 to 2011. Moreover, we obtain also some evidence that the value of political connections increased during the 2007 crisis period and onward.
Bank Financing, Institutions and Regional Entrepreneurial Activities: Evidence from China
in: International Review of Economics & Finance, November 2017
We investigate the effects of bank financing on regional entrepreneurial activities in China. We present contrasting findings on the role of quantity vs. quality of bank financing on small business formation in China: while we document a consistent, significantly positive relationship between the quality of bank financing and new venture formation, we find that the quantity of supplied credit is insignificant. We report that formal institutions are positively correlated to regional entrepreneurial activities, and informal institutions substitute formal institutions. Our findings also reveal that the institutional environment tends to supplement bank financing in promoting regional entrepreneurial activities.
Bank Overall Financial Strength: Islamic Versus Conventional Banks
in: Economic Modelling, 2017
A number of recent studies compare the performance of Islamic and conventional banks with the use of individual financial ratios or efficiency frontier techniques. The present study extends this strand of the literature, by comparing Islamic banks, conventional banks, and banks with an Islamic window with the use of a bank overall financial strength index. This index is developed with a multicriteria methodology that allows us to aggregate various criteria capturing bank capital strength, asset quality, earnings, liquidity, and management quality in controlling expenses. We find that banks differ significantly in terms of individual financial ratios; however, the difference of the overall financial strength between Islamic and conventional banks is not statistically significant. This finding is confirmed with both univariate comparisons and in multivariate regression estimations. When we look at the bank financial strength within regions, we find that conventional banks outperform both the Islamic banks and the banks with Islamic window in the case of Asia and the Gulf Cooperation Council; however, Islamic banks perform better in the MENA and Senegal region. Second stage regressions also reveal that the bank overall financial strength index is influenced by various country-specific attributes. These include control of corruption, government effectiveness, and operation in one of the seven countries that are expected to drive the next big wave in Islamic finance.
Enforceability of Noncompetition Agreements and Firm Innovation: Does State Regulation Matter?
in: Innovation, No. 2, 2017
In this study, we examine how noncompetition agreements and the mobility of human capital – a core asset of any firm – affect innovations of publicly traded firms in the United States. We find that firms in states with stricter noncompetition enforcement have fewer patent applications. We also examine patent forward citations and find that tougher enforcement of such contracts is associated with less innovative patents. Notably, we find that stronger enforcement of noncompetition agreements impedes innovation for firms facing intense industry labor mobility. High-powered, equity-based compensation positively moderates the relationship between noncompetition enforcement and innovation, but only for the quality of innovation.
Monetary Policy under the Microscope: Intra-bank Transmission of Asset Purchase Programs of the ECB
in: IWH Discussion Papers, No. 9, 2015
With a unique loan portfolio maintained by a top-20 universal bank in Germany, this study tests whether unconventional monetary policy by the European Central Bank (ECB) reduced corporate borrowing costs. We decompose corporate lending rates into refinancing costs, as determined by money markets, and markups that the bank is able to charge its customers in regional markets. This decomposition reveals how banks transmit monetary policy within their organizations. To identify policy effects on loan rate components, we exploit the co-existence of eurozone-wide security purchase programs and regional fiscal policies at the district level. ECB purchase programs reduced refinancing costs significantly, even in an economy not specifically targeted for sovereign debt stress relief, but not loan rates themselves. However, asset purchases mitigated those loan price hikes due to additional credit demand stimulated by regional tax policy and enabled the bank to realize larger economic margins.
Corporate Governance Structures and Financial Constraints in Multinational Enterprises – An Analysis in Selected European Transition Economies on the Basis of the IWH FDI Micro Database 2013 –
in: IWH Discussion Papers, No. 3, 2015
In our analysis, we consider the distribution of decision power over financing and investment between MNEs’ headquarters and foreign subsidiaries and its influence on the foreign affiliates’ financial restrictions. Our research results show that headquarters of multinational enterprises have not (yet) moved much decision power to their foreign subsidiaries at all. We use data from the IWH FDI Micro Database which contains information on corporate governance structures and financial restrictions of 609 enterprises with a foreign investor in Hungary, Poland, the Czech Republic, Slovakia, Romania and East Germany. We match data from Bureau van Dijk’s AMADEUS database on financial characteristics. We find that a high concentration of decision power within the MNE’s headquarter implicates high financial restrictions within the subsidiary. Square term results show, however, that the effect of financial constraints within the subsidiary decreases and finally turns insignificant when decision power moves from headquarter to subsidiary. Thus, economic policy should encourage foreign investors in the case of foreign acquisition of local enterprises to leave decision power within the enterprise and in the case of Greenfield investment to provide the newly established subsidiaries with as much power over corporate governance structures as possible.
