Financial market reaction to poll data suggests strong effects of a Brexit on exchange rates and the banking system both in the UK and in the EU
On 23 June 2016, there will be a referendum in the United Kingdom (UK) on the question of whether or not the country should remain in the European Union (EU). We use the polls as a measure of the likelihood of an exit to examine the likely effect of a Brexit on financial markets. “Whenever the probability in the polls of a Brexit moves above 50%, we observe a substantial depreciation of the UK pound with respect to most major currencies (including the euro), and strong decline in bank stock prices, suggesting that markets feel the financial sector (both in the UK and the EU) will be most severely affected by a Brexit”, IWH President Reint E. Gropp says. There is little effect on the euro/US Dollar exchange rate. “A huge concern is that overall market volatility both in the UK and the EU are on record highs since last Thursday, reflecting the higher uncertainty associated with Brexit and how exactly, if it happened, it would come about.” Within the UK, we see some evidence for a flight to safety into UK government bonds, but no effects for German bonds.

Exporting Liquidity: Branch Banking and Financial Integration
Erik P. Gilje, Elena Loutskina, Philip E. Strahan
Journal of Finance,
No. 3,
2016
Abstract
Using exogenous liquidity windfalls from oil and natural gas shale discoveries, we demonstrate that bank branch networks help integrate U.S. lending markets. Banks exposed to shale booms enjoy liquidity inflows, which increase their capacity to originate and hold new loans. Exposed banks increase mortgage lending in nonboom counties, but only where they have branches and only for hard‐to‐securitize mortgages. Our findings suggest that contracting frictions limit the ability of arm's length finance to integrate credit markets fully. Branch networks continue to play an important role in financial integration, despite the development of securitization markets.

Time-varying Volatility, Financial Intermediation and Monetary Policy
S. Eickmeier, N. Metiu, Esteban Prieto
IWH Discussion Papers,
No. 19,
2016
Abstract
We document that expansionary monetary policy shocks are less effective at stimulating output and investment in periods of high volatility compared to periods of low volatility, using a regime-switching vector autoregression. Exogenous policy changes are identified by adapting an external instruments approach to the non-linear model. The lower effectiveness of monetary policy can be linked to weaker responses of credit costs, suggesting a financial accelerator mechanism that is weaker in high volatility periods. To rationalize our robust empirical results, we use a macroeconomic model in which financial intermediaries endogenously choose their capital structure. In the model, the leverage choice of banks depends on the volatility of aggregate shocks. In low volatility periods, financial intermediaries lever up, which makes their balance sheets more sensitive to aggregate shocks and the financial accelerator more effective. On the contrary, in high volatility periods, banks decrease leverage, which renders the financial accelerator less effective; this in turn decreases the ability of monetary policy to improve funding conditions and credit supply, and thereby to stimulate the economy. Hence, we provide a novel explanation for the non-linear effects of monetary stimuli observed in the data, linking the effectiveness of monetary policy to the procyclicality of leverage.

The Role of Complexity for Bank Risk during the Financial Crisis: Evidence from a Novel Dataset
Thomas Krause, Talina Sondershaus, Lena Tonzer
Abstract
We construct a novel dataset to measure banks’ business and geographical complexity. Using these measures of complexity, we evaluate how they relate to banks’ idiosyncratic and systemic riskiness. The sample covers stock listed banks in the euro area from 2007 to 2014. Our results show that banks have increased their total number of subsidiaries while business and geographical complexity have declined. Bank stability is significantly affected by our complexity measures, whereas the direction of the effect differs across the complexity measures: Banks with a higher degree of geographical complexity and a higher share of foreign subsidiaries seem to be less stable. In contrast, a higher share of non-bank subsidiaries significantly decreases the probability for a state aid request during the recent crisis period. This heterogeneity advises against the use of a single complexity measure when evaluating the implications of bank complexity.

Central Bank Transparency and Cross-border Banking
Stefan Eichler, Helge Littke, Lena Tonzer
Abstract
We analyze the effect of central bank transparency on cross-border bank activities. Based on a panel gravity model for cross-border bank claims for 21 home and 47 destination countries from 1998 to 2010, we find strong empirical evidence that a rise in central bank transparency in the destination country, on average, increases cross-border claims. Using interaction models, we find that the positive effect of central bank transparency on cross-border claims is only significant if the central bank is politically independent. Central bank transparency and credibility are thus considered complements by banks investing abroad.

Wirtschaft im Wandel,
No. 2,
2016
Abstract
Der Euroraum verharrt in einer tiefen, vierfachen Krise. Die erste ist eine Wachstumskrise. Im Euroraum liegt die wirtschaftliche Leistung immer noch unterhalb des Niveaus von vor der Finanzkrise 2008. Zudem leidet der Euroraum weiterhin unter hoher Arbeitslosigkeit und zu niedriger Inflation. Der Euroraum leidet außerdem unter einem zu geringen Produktivitätswachstum, vor allem bei den Dienstleistungen. Es fehlt hier an Innovationsdynamik und Investitionen.

Regional Banking Instability and FOMC Voting
Stefan Eichler, Tom Lähner, Felix Noth
Abstract
This study analyzes if regionally affiliated Federal Open Market Committee (FOMC) members take their districts’ regional banking sector instability into account when they vote. Considering the period from 1978 to 2010, we find that a deterioration in a district’s bank health increases the probability that this district’s representative in the FOMC votes to ease interest rates. According to member-specific characteristics, the effect of regional banking sector instability on FOMC voting behavior is most pronounced for Bank presidents (as opposed to governors) and FOMC members who have career backgrounds in the financial industry or who represent a district with a large banking sector.

Are Lacking Structural Reforms in the Financial Sector the Underlying Reason for the German Criticism of the ECB?
The major reason for the intense criticism of the European Central Bank’s (ECB’s) low-interest-rate policy may be the lack of structural reforms in the German banking system. The resulting persistent fragmentation increases the banking sector’s vulnerability to the low-interest-rate environment. Hence, parts of the banking sector, due to their strong ties to politicians, appear to have successfully influenced public opinion against the ECB.

Measuring Income Tax Evasion Using Bank Credit: Evidence from Greece
Nikolaos Artavanis, Adair Morse, Margarita Tsoutsoura
Quarterly Journal of Economics,
No. 2,
2016
Abstract
We document that in semiformal economies, banks lend to tax-evading individuals based on the bank’s assessment of the individual’s true income. This observation leads to a novel approach to estimate tax evasion. We use microdata on household credit from a Greek bank and replicate the bank underwriting model to infer the banks estimate of individuals’ true income. We estimate that 43–45% of self-employed income goes unreported and thus untaxed. For 2009, this implies €28.2 billion of unreported income, implying forgone tax revenues of over €11 billion or 30% of the deficit. Our method innovation allows for estimating the industry distribution of tax evasion in settings where uncovering the incidence of hidden cash transactions is difficult using other methods. Primary tax-evading industries are professional services—medicine, law, engineering, education, and media. We conclude with evidence that contemplates the importance of institutions, paper trail, and political willpower for the persistence of tax evasion.

Hold-up and the Use of Performance-sensitive Debt
Tim R. Adam, Daniel Streitz
Journal of Financial Intermediation,
April
2016
Abstract
We examine whether performance-sensitive debt (PSD) is used to reduce hold-up problems in long-term lending relationships. We find that the use of PSD is more common in the presence of a long-term lending relationship and if the borrower has fewer financing alternatives available. In syndicated deals, however, the presence of a relationship lead arranger reduces the use of PSD because a lead arranger has little incentive to hold-up a client. Further supporting the hypothesis that hold-up concerns motivate the use of PSD, we find a substitution effect between the use of PSD and the tightness of financial covenants.
