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.

Credit Supply Shocks: Financing Real Growth or Takeovers?
in: Review of Corporate Finance Studies, im Erscheinen
Abstract
How do firms invest when financial constraints are relaxed? We document that firms affected by a large positive credit supply shock predominantly increase borrowing for transaction-based purposes. These treated firms have larger asset and employment growth rates; however, growth entirely stems from the increased takeover activity. Announcement returns indicate a low quality of the credit-supply-induced takeover activity. These results offer the possibility that credit-driven growth can simply reflect redistribution, rather than net gains in assets or employment.

Trust, Politics and Post-IPO Performance: SOEs vs. the Private Sector
in: Economic and Political Studies, im Erscheinen
Abstract
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, 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.

Firm Social Networks, Trust, and Security Issuances
in: European Journal of Finance, Nr. 4, 2022
Abstract
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.

Social Capital, Trusting, and Trustworthiness: Evidence from Peer-to-Peer Lending
in: Journal of Financial and Quantitative Analysis, Nr. 4, 2022
Abstract
How does social capital affect trust? Evidence from a Chinese peer-to-peer lending platform shows regional social capital affects the trustee’s trustworthiness and the trustor’s trust propensity. Ceteris paribus, borrowers from higher social capital regions receive larger bid from individual lenders, have higher funding success, larger loan size, and lower default rates, especially for low-quality borrowers. Lenders from higher social capital regions take higher risks and have higher default rates, especially for inexperienced lenders. Cross-regional transactions are most (least) likely to be realized between parties from high (low) social capital regions.

Cultural Norms and Corporate Fraud: Evidence from the Volkswagen Scandal
in: IWH Discussion Papers, 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.

Trade Shocks, Credit Reallocation and the Role of Specialisation: Evidence from Syndicated Lending
in: IWH Discussion Papers, Nr. 15, 2020
Abstract
This paper provides evidence that banks cut lending to US borrowers as a consequence of a trade shock. This adverse reaction is stronger for banks with higher ex-ante lending to US industries hit by the trade shock. Importantly, I document large heterogeneity in banks‘ reaction depending on their sectoral specialisation. Banks shield industries in which they are specialised in and at the same time reduce the availability of credit to industries they are not specialised in. The latter is driven by low-capital banks and lending to firms that are themselves hit by the trade shock. Banks‘ adjustments have adverse real effects.

Spillovers of Asset Purchases Within the Real Sector: Win-Win or Joy and Sorrow?
in: IWH Discussion Papers, Nr. 22, 2019
Abstract
Events which have an adverse or positive effect on some firms can disseminate through the economy to firms which are not directly affected. By exploiting the first large sovereign bond purchase programme of the ECB, this paper investigates whether more lending to some firms spill over to firms in the surroundings of direct beneficiaries. Firms operating in the same industry and region invest less and reduce employment. The paper shows the importance to consider spillover effects when assessing unconventional monetary policies: Differences between treatment and control groups can be entirely attributed to negative effects on the control group.

Do Asset Purchase Programmes Shape Industry Dynamics? Evidence from the ECB's SMP on Plant Entries and Exits
in: IWH Discussion Papers, Nr. 12, 2019
Abstract
Asset purchase programmes (APPs) may insulate banks from having to terminate relationships with unproductive customers. Using administrative plant and bank data, we test whether APPs impinge on industry dynamics in terms of plant entry and exit. Plants in Germany connected to banks with access to an APP are approximately 20% less likely to exit. In particular, unproductive plants connected to weak banks with APP access are less likely to close. Aggregate entry and exit rates in regional markets with high APP exposures are also lower. Thus, APPs seem to subdue Schumpeterian cleansing mechanisms, which may hamper factor reallocation and aggregate productivity growth.

‘And Forgive Us Our Debts’: Do Christian Moralities Influence Over-indebtedness of Individuals?
in: IWH Discussion Papers, Nr. 8, 2019
Abstract
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.
