Shock Propagation and Banking Structure
Mariassunta Giannetti, Farzad Saidi
Review of Financial Studies,
Vol. 32 (7),
2019
Abstract
We explore whether lenders’ decisions to provide liquidity in periods of distress are affected by the extent to which they internalize the negative spillovers of industry downturns. We conjecture that high-market-share lenders are more likely to internalize negative spillovers and show that they provide liquidity to industries in distress when fire sales are likely to ensue. High-market-share lenders also provide liquidity to customers and suppliers of distressed industries when the disruption of supply chains is expected to be costly. Our results suggest a novel channel to explain why credit concentration may favor financial stability.

Life below Zero: Bank Lending under Negative Policy Rates
Florian Heider, Farzad Saidi, Glenn Schepens
Review of Financial Studies,
Vol. 32 (10),
2019
Abstract
We show that negative policy rates affect the supply of bank credit in a novel way. Banks are reluctant to pass on negative rates to depositors, which increases the funding cost of high-deposit banks, and reduces their net worth, relative to low-deposit banks. As a consequence, the introduction of negative policy rates by the European Central Bank in mid-2014 leads to more risk-taking and less lending by euro-area banks with a greater reliance on deposit funding. Our results suggest that negative rates are less accommodative and could pose a risk to financial stability, if lending is done by high-deposit banks.

Health Externalities and Policy: The Role of Social Preferences
Laura Alfaro, Nora Lamersdorf, Farzad Saidi
Management Science,
Vol. 68 (9),
2022
Abstract
Social preferences facilitate the internalization of health externalities, for example, by reducing mobility during a pandemic. We test this hypothesis using mobility data from 258 cities worldwide alongside experimentally validated measures of social preferences. Controlling for time-varying heterogeneity that could arise at the level at which mitigation policies are implemented, we find that they matter less in regions that are more altruistic, patient, or exhibit less negative reciprocity. In those regions, mobility falls ahead of lockdowns, and remains low after the lifting thereof. Our results elucidate the importance, independent of the cultural context, of social preferences in fostering cooperative behavior.

Regulatory Forbearance in the U.S. Insurance Industry: The Effects of Removing Capital Requirements for an Asset Class
Bo Becker, Marcus Matthias Opp, Farzad Saidi
Review of Financial Studies,
Vol. 35 (12),
2022
Abstract
We analyze the effects of a reform of capital regulation for U.S. insurance companies in 2009. The reform eliminates capital buffers against unexpected losses associated with portfolio holdings of MBS, but not for other fixed-income assets. After the reform, insurance companies are much more likely to retain downgraded MBS compared to other downgraded assets. This pattern is more pronounced for financially constrained insurers. Exploiting discontinuities in the reform’s implementation, we can identify the relevance of the capital requirements channel. We also document that the insurance industry crowds outs other investors in the new issuance of (high-yield) MBS.

The Role of State-owned Banks in Crises: Evidence from German Banks During COVID-19
Xiang Li
IWH Discussion Papers,
Nr. 6,
2022
Abstract
By adopting a difference-in-differences specification combined with propensity score matching, I provide evidence using the microdata of German banks that stateowned savings banks have lent less than credit cooperatives during the COVID-19 crisis. In particular, the weaker lending effects of state-owned banks are pronounced for long-term and nonrevolving loans but insignificant for short-term and revolving loans. Moreover, the negative impact of government ownership is larger for borrowers who are more exposed to the COVID-19 shock and in regions where the ruling parties are longer in office and more positioned on the right side of the political spectrum.

Firm Subsidies, Financial Intermediation, and Bank Risk
Aleksandr Kazakov, Michael Koetter, Mirko Titze, Lena Tonzer
Abstract
We study whether government subsidies can stimulate bank funding of marginal investment projects and the associated effect on financial stability. We do so by exploiting granular project-level information for the largest regional economic development programme in Germany since 1997: the Improvement of Regional Economic Structures programme (GRW). By combining the universe of subsidised firms to virtually all German local banks over the period 1998-2019, we test whether this large-scale transfer programme destabilised regional credit markets. Because GRW subsidies to firms are destabilised at the EU level, we can use it as an exogenous shock to identify bank responses. On average, firm subsidies do not affect bank lending, but reduce banks’ distance to default. Average effects conflate important bank-level heterogeneity though. Conditional on various bank traits, we show that well capitalised banks with more industry experience expand lending when being exposed to subsidised firms without exhibiting more risky financial profiles. Our results thus indicate that stable banks can act as an important facilitator of regional economic development policies. Against the backdrop of pervasive transfer payments to mitigate Covid-19 losses and in light of far-reaching transformation policies required to green the economy, our study bears important implications as to whether and which banks to incorporate into the design of transfer Programmes.

Is there an Information Channel of Monetary Policy?
Oliver Holtemöller, Alexander Kriwoluzky, Boreum Kwak
Abstract
Exploiting the heteroscedasticity of the changes in short-term and long-term interest rates and exchange rates around the FOMC announcement, we identify three structural monetary policy shocks. We eliminate the predictable part of the shocks and study their effects on financial variables and macro variables. The first shock resembles a conventional monetary policy shock, and the second resembles an unconventional monetary shock. The third shock leads to an increase in interest rates, stock prices, industrial production, consumer prices, and commodity prices. At the same time, the excess bond premium and uncertainty decrease, and the U.S. dollar depreciates. Therefore, this third shock combines all the characteristics of a central bank information shock.
