Abstract
This paper compares the out-of-sample predictive performance of different early warning models for systemic banking crises using a sample of advanced economies covering the past 45 years. We compare a benchmark logit approach to several machine learning approaches recently proposed in the literature. We find that while machine learning methods often attain a very high in-sample fit, they are outperformed by the logit approach in recursive out-of-sample evaluations. This result is robust to the choice of performance metric, crisis definition, preference parameter, and sample length, as well as to using different sets of variables and data transformations. Thus, our paper suggests that further enhancements to machine learning early warning models are needed before they are able to offer a substantial value-added for predicting systemic banking crises. Conventional logit models appear to use the available information already fairly efficiently, and would for instance have been able to predict the 2007/2008 financial crisis out-of-sample for many countries. In line with economic intuition, these models identify credit expansions, asset price booms and external imbalances as key predictors of systemic banking crises.

Firm-level Employment, Labour Market Reforms, and Bank Distress
Moritz Stieglitz, Ralph Setzer
Abstract
We explore the interaction between labour market reforms and financial frictions. Our study combines a new cross-country reform database on labour market reforms with matched firm-bank data for nine euro area countries over the period 1999 to 2013. While we find that labour market reforms are overall effective in increasing employment, restricted access to bank credit can undo up to half of long-term employment gains at the firm-level. Entrepreneurs without sufficient access to credit cannot reap the full benefits of more flexible employment regulation.

Mind the Gap: The Difference Between U.S. and European Loan Rates
Tobias Berg, Anthony Saunders, Sascha Steffen, Daniel Streitz
Review of Financial Studies,
Nr. 3,
2017
Abstract
We analyze pricing differences between U.S. and European syndicated loans over the 1992–2014 period. We explicitly distinguish credit lines from term loans. For credit lines, U.S. borrowers pay significantly higher spreads, but lower fees, resulting in similar total costs of borrowing in both markets. Credit line usage is more cyclical in the United States, which provides a rationale for the pricing structure difference. For term loans, we analyze the channels of the cross-country loan price differential and document the importance of: the composition of term loan borrowers and the loan supply by institutional investors and foreign banks.

The Impact of Credit Default Swap Trading on Loan Syndication
Daniel Streitz
Review of Finance,
Nr. 1,
2016
Abstract
We analyze the impact of credit default swap (CDS) trading on bank syndication activity. Theoretically, the effect of CDS trading is ambiguous: on the one hand, CDS can improve risk-sharing and hence be a more flexible risk management tool than loan syndication; on the other hand, CDS trading can reduce bank monitoring incentives. We document that banks are less likely to syndicate loans and retain a larger loan fraction once CDS are actively traded on the borrower’s debt. We then discern the risk management and the moral hazard channel. We find no evidence that the reduced likelihood to syndicate loans is a result of increased moral hazard problems.

The Impact of Securitization on Credit Rationing: Empirical Evidence
Santiago Carbo-Valverde, Hans Degryse, Francisco Rodríguez-Fernández
Journal of Financial Stability,
2015
Abstract
We study whether banks’ involvement into different types of securitization activity – asset backed securities (ABS) and covered bonds – in Spain influences credit supply before and during the financial crisis. While both ABS and covered bonds were hit by the crisis, the former were hit more severely. Employing a disequilibrium model to identify credit rationing, we find that firms with banks that were more involved in securitization see their credit constraints more relaxed in normal periods. In contrast, only greater covered bonds issuance reduces credit rationing during crisis periods whereas ABS aggravates these firms’ credit rationing in crisis periods. Our results are in line with the theoretical predictions that a securitization instrument that retains risk (covered bond) may induce a more prudent risk behavior of banks than an instrument that provides risk transferring (ABS).

New IMF Lending Facilities and Financial Stability in Emerging Markets
J. John, Tobias Knedlik
Economic Analysis and Policy,
Nr. 2,
2011
Abstract
In the light of the current global financial and economic crisis, the International Monetary Fund (IMF) has undertaken some major reforms of its lending facilities. The new Flexible Credit Line and the High Access Precautionary Arrangements differ from what has been in place so far, by allowing for ex ante conditionality. This paper summarizes preconditions for effective last resort lending and evaluates the newly introduced measures, concluding that the Flexible Credit Line comes very close to what has been called an International Lender of Last Resort. The main obstacles are the low demand and slow progress in complementary reforms.

Central and Eastern European Countries in the Global Financial Crisis: A Typical Twin Crisis?
Diemo Dietrich, Tobias Knedlik, Axel Lindner
Post-Communist Economies,
Nr. 4,
2011
Abstract
This paper shows that during the Great Recession, banking and currency crises occurred simultaneously in Central and Eastern Europe. Events, however, differed widely from what happened during the Asian crisis that usually serves as the model case for the concept of twin crises. We look at three elements that help explaining the nature of events in Central and Eastern Europe: the problem of currency mismatches, the relation between currency and banking crises, and the importance of multinational banks for financial stability. It is shown that theoretical considerations concerning internal capital markets of multinational banks help understand what happened on capital markets and in the financial sector of the region. We discuss opposing effects of multinational banking on financial stability and find that institutional differences are the key to understand differing effects of the global financial crisis. In particular, we argue that it matters if international activities are organized by subsidiaries or by cross-border financial services, how large the share of foreign currency-denominated credit is and whether the exchange rate is fixed or flexible. Based on these three criteria we give an explanation why the pattern of the crisis in the Baltic States differed markedly from that in Poland and the Czech Republic, the two largest countries of the region.

Reform der Kreditvergabe des IWF erhöht die Stabilität in Schwellenländern
J. John, Tobias Knedlik
Wirtschaft im Wandel,
Nr. 3,
2010
Abstract
Im Zuge der aktuellen Finanz- und Konjunkturkrise gewann der Internationale Währungsfonds (IWF) stark an Bedeutung. Dies zeigte sich vor allem in der erheblichen Ausweitung der verfügbaren Mittel des Fonds. Im Zuge der Krise wurden auch die Kreditlinien des IWF überarbeitet. Zwei neue Instrumente sind dabei von besonderem Interesse, die Flexible Credit Line (FCL) und die High
Access Precautionary Arrangements (HAPA). Nachdem bereits früher mit präventiven Kreditlinien experimentiert wurde, ist die FCL das erste Kreditinstrument mit vorgelagertem Qualifikationsprozess, das auch auf Nachfrage stieß. Dabei ersetzt die Ex-ante-Qualifikation die bisher bei allen IWF-Krediten übliche Ex-post-Konditionalität. Dies bedeutet, dass qualifizierte Länder im Falle einer Krise direkt auf die IWFMittel zurückgreifen können. Ein langwieriger Verhandlungsprozess ist damit ebenso obsolet wie die häufig kritisierten begleitenden Reformprogramme. Damit erfüllt der IWF nunmehr wesentliche Voraussetzungen für eine präventive Kreditvergabe. Auch die befürchtete Stigmatisierung der Länder, die Interesse an den neuen Krediten zeigten, blieb
bislang aus. Die Indikatoren für Polen, Mexiko und Kolumbien, also jener Länder, die bisher FCLVereinbarungen geschlossen haben, sind positiv. Die neuen Instrumente dürften deshalb die Stabilität in Schwellenländern erhöhen.
Kritisch zu betrachten bleibt jedoch die Gefahr erhöhter Risikobereitschaft durch die Finanzmarktakteure, solange die Kreditinstrumente nicht von einem effektiven regulatorischen Rahmen begleitet werden. Die systemische Bedeutung der neuen
Kreditinstrumente wird zudem durch die bislang geringe Nachfrage geschmälert.
