Supranational Rules, National Discretion: Increasing versus Inflating Regulatory Bank Capital?
Reint E. Gropp, Thomas Mosk, Steven Ongena, Ines Simac, Carlo Wix
Abstract
We study how higher capital requirements introduced at the supranational and implemented at the national level affect the regulatory capital of banks across countries. Using the 2011 EBA capital exercise as a quasi-natural experiment, we find that affected banks inflate their levels of regulatory capital without a commensurate increase in their book equity and without a reduction in bank risk. This observed regulatory capital inflation is more pronounced in countries where credit supply is expected to tighten. Our results suggest that national authorities forbear their domestic banks to meet supranational requirements, with a focus on short-term economic considerations.

Supranational Rules, National Discretion: Increasing versus Inflating Regulatory Bank Capital
Reint E. Gropp, Thomas Mosk, Steven Ongena, Ines Simac, Carlo Wix
Abstract
The implementation of supranational regulations at the national level often provides national authorities with substantial room to engage in discretion and forbearance. Using evidence from a supranational increase in bank capital requirements, this column shows that national authorities may assist banks' efforts to inflate their regulatory capital to pass such supranational requirements. While supranational rules should be binding in theory, national discretion may effectively undermine them in practice.

Real Estate Transaction Taxes and Credit Supply
Michael Koetter, Philipp Marek, Antonios Mavropoulos
Deutsche Bundesbank Discussion Paper,
No. 4,
2021
Abstract
We exploit staggered real estate transaction tax (RETT) hikes across German states to identify the effect of house price changes on mortgage credit supply. Based on approximately 33 million real estate online listings, we construct a quarterly hedonic house price index (HPI) between 2008:q1 and 2017:q4, which we instrument with state-speci c RETT changes to isolate the effect on mortgage credit supply by all local German banks. First, a RETT hike by one percentage point reduces HPI by 1.2%. This effect is driven by listings in rural regions. Second, a 1% contraction of HPI induced by an increase in the RETT leads to a 1.4% decline in mortgage lending. This transmission of fiscal policy to mortgage credit supply is effective across almost the entire bank capitalization distribution.

A Note of Caution on Quantifying Banks' Recapitalization Effects
Felix Noth, Kirsten Schmidt, Lena Tonzer
Abstract
Unconventional monetary policy measures like asset purchase programs aim to reduce certain securities' yield and alter financial institutions' investment behavior. These measures increase the institutions' market value of securities and add to their equity positions. We show that the extent of this recapitalization effect crucially depends on the securities' accounting and valuation methods, country-level regulation, and maturity structure. We argue that future research needs to consider these factors when quantifying banks' recapitalization effects and consequent changes in banks' lending decisions to the real sector.

Benign Neglect of Covenant Violations: Blissful Banking or Ignorant Monitoring
Stefano Colonnello, Michael Koetter, Moritz Stieglitz
Economic Inquiry,
No. 1,
2021
Abstract
Theoretically, bank's loan monitoring activity hinges critically on its capitalization. To proxy for monitoring intensity, we use changes in borrowers' investment following loan covenant violations, when creditors can intervene in the governance of the firm. Exploiting granular bank‐firm relationships observed in the syndicated loan market, we document substantial heterogeneity in monitoring across banks and through time. Better capitalized banks are more lenient monitors that intervene less with covenant violators. Importantly, this hands‐off approach is associated with improved borrowers' performance. Beyond enhancing financial resilience, regulation that requires banks to hold more capital may thus also mitigate the tightening of credit terms when firms experience shocks.

The Real Impact of Ratings-based Capital Rules on the Finance-Growth Nexus
Iftekhar Hasan, Gazi Hassan, Suk-Joong Kim, Eliza Wu
International Review of Financial Analysis,
January
2021
Abstract
We investigate whether ratings-based capital regulation has affected the finance-growth nexus via a foreign credit channel. Using quarterly data on short to medium term real GDP growth and cross-border bank lending flows from G-10 countries to 67 recipient countries, we find that since the implementation of Basel 2 capital rules, risk weight reductions mapped to sovereign credit rating upgrades have stimulated short-term economic growth in investment grade recipients but hampered growth in non-investment grade recipients. The impact of these rating upgrades is strongest in the first year and then reverses from the third year and onwards. On the other hand, there is a consistent and lasting negative impact of risk weight increases due to rating downgrades across all recipient countries. The adverse effects of ratings-based capital regulation on foreign bank credit supply and economic growth are compounded in countries with more corruption and less competitive banking sectors and are attenuated with greater political stability.

Drawing Conclusions from Structural Vector Autoregressions Identified on the Basis of Sign Restrictions
Christiane Baumeister, James D. Hamilton
Journal of International Money and Finance,
December
2020
Abstract
This paper discusses the problems associated with using information about the signs of certain magnitudes as a basis for drawing structural conclusions in vector autoregressions. We also review available tools to solve these problems. For illustration we use Dahlhaus and Vasishtha’s (2019) study of the effects of a U.S. monetary contraction on capital flows to emerging markets. We explain why sign restrictions alone are not enough to allow us to answer the question and suggest alternative approaches that could be used.

Why Life Insurers are Key to Economic Dynamism in Germany
Reint E. Gropp, William McShane
IWH Online,
No. 6,
2020
Abstract
Young entrepreneurial firms are of critical importance for innovation. But to bring their new ideas to the market, these startups depend on investors who understand and are willing to accept the risk associated with a new firm. Perhaps the key reason as to why the US has succeeded in producing nearly all the most successful new firms of the 21st century is the economy’s ability to supply vast sums of capital to promising startups. The volume of venture capital (VC) invested in the US is more than 60 times that of Germany. In this policy note, we argue that differences in the regulatory and structural context of institutional investors, in particular life insurance companies, is a central driver of the relative lack of VC - and thereby successful startups - in Germany.

The Impact of Social Capital on Economic Attitudes and Outcomes
Iftekhar Hasan, Qing He, Haitian Lu
Journal of International Money and Finance,
November
2020
Abstract
This article traces the extant literature on the impact of social capital on economic attitudes and outcomes. Special attention is paid to clarify conceptual ambiguities, measurement techniques, channels of influence, and identification strategies. Insights derived from the literature are then used to analyze the marketplace lending industry in China, where the size of the peer-to-peer (P2P) lending market is larger than that of the rest of the world combined. Ironically, approximately two-thirds of these online P2P lending platforms have failed. Empirical evidence from the monthly operating data of 735 lending platforms and transaction level data from one prominent platform (Renrendai) shows that platforms in provinces with high social capital have low risk of failure, and borrowers in provinces with high social capital can borrow at low interest rate and are less likely to default. We also provide observations to guide future economic research on social capital.
