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.

Trust, Politics and Post-IPO Performance: SOEs vs. the Private Sector
in: Economic and Political Studies, forthcoming
This paper empirically investigates the role of social trust in the long-term performance of the initial public offerings (IPOs) in China, controlling for the formal institutional environment. We find that privately owned or smaller IPO firms experience significantly better post-IPO performance when they are incorporated in regions with more social trust. The state-owned and bigger IPO firms, on the other hand, experience better long-term post-IPO performance when they are incorporated in regions with stronger formal institutions (e.g. court enforcement and contract holding). Political pluralism turns out to benefit all IPOs in the long term. In addition, our evidence shows that stronger social trust substitutes for the quality of court enforcement but complements the role of contract holding. These results are robust after controlling for alternative definitions of ownership, outliers, non-linear effects of institutions, and the potential endogeneity of institutions in the model.
Social Capital and Regional Innovation: Evidence from Private Firms in the US
in: Regional Studies, No. 1, 2023
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
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.
The Impact of Financial Transaction Taxes on Stock Markets: Short-Run Effects, Long-Run Effects, and Reallocation of Trading Activity
in: National Tax Journal, No. 3, 2022
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.
Firm Social Networks, Trust, and Security Issuances
in: European Journal of Finance, No. 4, 2022
We observe that public firms are more likely to issue seasoned stocks rather than bonds when theirs boards are more socially-connected. These connected issuers experience better announcement-period stock returns and attract more institutional investors. This social-connection effect is stronger for firms with severe information asymmetry, higher risk of being undersubscribed, and more visible to investors. Our conjecture is this social-network effect is driven by trust in issuing firms. Given stocks are more sensitive to trust, these trusted firms are more likely to issue stocks than bonds. Trustworthiness plays an important role in firms’ security issuances in capital markets.
‘And Forgive Us Our Debts’: Do Christian Moralities Influence Over-indebtedness of Individuals?
in: IWH Discussion Papers, No. 8, 2019
This paper analyses whether Christian moralities and rules formed differently by Catholics and Protestants impact the likelihood of households to become overindebted. We find that over-indebtedness is lower in regions in which Catholics outweigh Protestants, indicating that Catholics‘ forgiveness culture and a stricter enforcement of rules by Protestants serve as explanations for our results. Our results provide evidence that religion affects the financial situations of individuals and show that even 500 years after the split between Catholics and Protestants, the differences in the mind-sets of both denominations play an important role for situations of severe financial conditions.
What Drives Banks‘ Geographic Expansion? The Role of Locally Non-diversifiable Risk
in: IWH Discussion Papers, No. 6, 2019
We show that banks that are facing relatively high locally non-diversifiable risks in their home region expand more across states than banks that do not face such risks following branching deregulation in the 1990s and 2000s. These banks with high locally non-diversifiable risks also benefit relatively more from deregulation in terms of higher bank stability. Further, these banks expand more into counties where risks are relatively high and positively correlated with risks in their home region, suggesting that they do not only diversify but also build on their expertise in local risks when they expand into new regions.
Politics, Banks, and Sub-sovereign Debt: Unholy Trinity or Divine Coincidence?
in: Deutsche Bundesbank Discussion Paper, No. 53, 2018
We exploit election-driven turnover in State and local governments in Germany to study how banks adjust their securities portfolios in response to the loss of political connections. We find that local savings banks, which are owned by their host county and supervised by local politicians, increase significantly their holdings of home-State sovereign bonds when the local government and the State government are dominated by different political parties. Banks' holdings of other securities, like federal bonds, bonds issued by other States, or stocks, are not affected by election outcomes. We argue that banks use sub-sovereign bond purchases to gain access to politically distant government authorities.
May the Force Be with You: Exit Barriers, Governance Shocks, and Profitability Sclerosis in Banking
in: Deutsche Bundesbank Discussion Paper, No. 49, 2018
We test whether limited market discipline imposes exit barriers and poor profitability in banking. We exploit an exogenous shock to the governance of government-owned banks: the unification of counties. County mergers lead to enforced government-owned bank mergers. We compare forced to voluntary bank exits and show that the former cause better bank profitability and efficiency at the expense of riskier financial profiles. Regarding real effects, firms exposed to forced bank mergers borrow more at lower cost, increase investment, and exhibit higher employment. Thus, reduced exit frictions in banking seem to unleash the economic potential of both banks and firms.
Banks Fearing the Drought? Liquidity Hoarding as a Response to Idiosyncratic Interbank Funding Dry-ups
in: IWH Discussion Papers, No. 12, 2018
Since the global financial crisis, economic literature has highlighted banks’ inclination to bolster up their liquid asset positions once the aggregate interbank funding market experiences a dry-up. To this regard, we show that liquidity hoarding and its detrimental effects on credit can also be triggered by idiosyncratic, i.e. bankspecific, interbank funding shocks with implications for monetary policy. Combining a unique data set of the Brazilian banking sector with a novel identification strategy enables us to overcome previous limitations for studying this phenomenon as a bankspecific event. This strategy further helps us to analyse how disruptions in the bank headquarters’ interbank market can lead to liquidity and lending adjustments at the regional bank branch level. From the perspective of the policy maker, understanding this market-to-market spillover effect is important as local bank branch markets are characterised by market concentration and relationship lending.
