Relationship Lenders and Unorthodox Monetary Policy: Investment, Employment, and Resource Reallocation Effects
Leibniz-Gemeinschaft
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.

Social Capital and Regional Innovation: Evidence from Private Firms in the US
in: Regional Studies, Nr. 1, 2023
Abstract
In this study we investigate whether and to what extent social capital may affect regional innovation by focusing on private firms in the United States. We document that regional social capital is positively associated with the quantity, quality and novelty of county-level innovation by private firms. In addition, we find that the positive relation between social capital and regional innovation is more prominent in counties with a lower supply of financial capital. We also report that social capital is complementary to investments in research and development to produce inventive outcomes in local areas. Using a spatial Durbin model, we provide evidence that regional social capital has significant spillover effects in boosting the innovation activities of neighbouring counties.

The Disciplining Effect of Supervisory Scrutiny in the EU-wide Stress Test
in: Journal of Financial Intermediation, January 2023
Abstract
Relying on confidential supervisory data related to the 2016 EU-wide stress test, this paper presents novel empirical evidence that supervisory scrutiny associated to stress testing has a disciplining effect on bank risk. We find that banks that participated in the 2016 EU-wide stress test subsequently reduced their credit risk relative to banks that were not part of this exercise. Relying on new metrics for supervisory scrutiny that measure the quantity, potential impact, and duration of interactions between banks and supervisors during the stress test, we find that the disciplining effect is stronger for banks subject to more intrusive supervisory scrutiny during the exercise. We also find that a strong risk management culture is a prerequisite for the supervisory scrutiny to be effective. Finally, we show that a similar disciplining effect is not exerted neither by higher capital charges nor by more transparency and related market discipline induced by the stress test.

Corporate Culture and Firm Value: Evidence from Crisis
in: Journal of Banking and Finance, January 2023
Abstract
Based on the Competing Values Framework (CVF), we score 10-K text to measure company culture in four types (collaborative, controlling, competitive, and creative) and examine its role in firm stability. We find that firms with higher controlling culture fared significantly better during the 2008–09 crisis. Firms with stronger controlling culture experienced fewer layoffs, less negative asset growth, greater debt issuance, and increased access to credit-line facilities during the crisis. The positive effect of the controlling culture is stronger among the financially-constrained firms. Overall, the controlling culture improves firm stability through greater support from capital providers.

Environmental Reputational Risk, Negative Media Attention and Financial Performance
in: Financial Markets, Institutions and Instruments, Nr. 4, 2022
Abstract
Tracing negative media attention, this paper investigates the effect of reputational risk on firm value. Decomposing reputational damage into environmental, social and corporate-governance dimensions, it reports that environmental reputational risk has the most significant negative effect on price earnings, i.e., firms exposed to environmental risk are likely to be priced at a discount or charged a higher risk premium when discounting future earnings.

The Impact of Financial Transaction Taxes on Stock Markets: Short-Run Effects, Long-Run Effects, and Reallocation of Trading Activity
in: National Tax Journal, Nr. 3, 2022
Abstract
We investigate the French 2012 financial transaction tax (FTT) and find robust evidence for anticipation effects before the implementation date. Controlling for short-run effects, we only find weak evidence for a long-run reduction in trading activity. Thus, the main impact of the French FTT on trading activity is short-run. In line with liquidity clientele effects, we find a more potent effect for low-liquidity stocks and a reallocation of trading to high-liquidity stocks from the Supplemental Liquidity Provider (SLP) program. Finally, we find weak evidence for a persistent volatility reduction but no indication of a significant FTT impact on price efficiency.

Flooded Through the Back Door: Firm-level Effects of Banks‘ Lending Shifts
in: IWH Discussion Papers, Nr. 4, 2018
Abstract
I show that natural disasters transmit to firms in non-disaster areas via their banks. This spillover of non-financial shocks through the banking system is stronger for banks with less regulatory capital. Firms connected to a disaster-exposed bank with below median capital reduce their employment by 11% and their fixed assets by 20% compared to firms in the same region without such a bank during the 2013 flooding in Germany. Relationship banking and higher firm capital also mitigate the effects of such negative cross-regional spillovers.

Bank-specific Shocks and House Price Growth in the U.S.
in: IWH Discussion Papers, Nr. 3, 2017
Abstract
This paper investigates the link between mortgage supply shocks at the banklevel and regional house price growth in the U.S. using micro-level data on mortgage markets from the Home Mortgage Disclosure Act for the 1990-2014 period. Our results suggest that bank-specific mortgage supply shocks indeed affect house price growth at the regional level. The larger the idiosyncratic shocks to newly issued mortgages, the stronger is house price growth. We show that the positive link between idiosyncratic mortgage shocks and regional house price growth is very robust and economically meaningful, however not very persistent since it fades out after two years.

How Effective is Macroprudential Policy during Financial Downturns? Evidence from Caps on Banks' Leverage
in: Working Papers of Eesti Pank, Nr. 7, 2015
Abstract
This paper investigates the effect of a macroprudential policy instrument, caps on banks' leverage, on domestic credit to the private sector since the Global Financial Crisis. Applying a difference-in-differences approach to a panel of 69 advanced and emerging economies over 2002–2014, we show that real credit grew after the crisis at considerably higher rates in countries which had implemented the leverage cap prior to the crisis. This stabilising effect is more pronounced for countries in which banks had a higher pre-crisis capital ratio, which suggests that after the crisis, banks were able to draw on buffers built up prior to the crisis due to the regulation. The results are robust to different choices of subsamples as well as to competing explanations such as standard adjustment to the pre-crisis credit boom.

Monetary Policy under the Microscope: Intra-bank Transmission of Asset Purchase Programs of the ECB
in: IWH Discussion Papers, Nr. 9, 2015
Abstract
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, Nr. 3, 2015
Abstract
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.
