An Assessment of Bank Merger Success in Germany

Abstract. German banks have experienced a merger wave since the early 1990s. However, the success of bank mergers remains a continuous matter of debate.This paper suggests a taxonomy to evaluate post-merger performance on the basis of cost and profit efficiency (CE and PE). I identify successful mergers as those that fulfill simultaneously two criteria. First, merged institutes must exhibit efficiency levels above the average of non-merging banks. Second, banks must exhibit efficiency changes between merger and evaluation year above efficiency changes of non-merging banks. I assess the post-merger performance up to 11 years after the mergers and relate it to the transfer of skills, the adequacy to merge distressed banks and the role of geographical distance. Roughly every second merger is a success in terms of either CE or PE. The margin of success in terms of CE is narrow, as efficiency differentials between merging and non-merging banks are around 1 and 2 percentage points. PE performance is slightly larger. More importantly, mergers boost in particular the change in PE, thus indicating persistent improvements of merging banks to improve the ability to generate profits.     

Global imbalances,cross-market linkages,and the financial crisis: A multivariate Markov-switching analysis

Based on multivariate Markov-switching models, this paper presents new results on the interactions between global imbalances, credit spreads, housing markets, macroeconomic variables, commodities and equities during Q1-1987/Q1-2011. We show that rising global imbalances and the uncontrolled development of the US mortgage and housing markets have been deeply destabilizing the economy, with various shocks impacting subsequently equity markets and macroeconomic variables. But we also uncover, surprisingly, that the cross-market linkages with the commodity markets are strong. Finally, we identify that the US housing market lies at the epicenter of the crisis through its multiple and highly significant interactions with the other variables in the system (including the global imbalances). Sub-samples and alternative time series estimates are provided to check the statistical congruency of the various models.     

Non linear and asymmetric linkages between real growth in the Euro area and global financial market conditions: New evidence

This paper deals with transition mechanisms through which financial market conditions affect real economic growth in the Euro area. The informational content of financial variables for predicting real economic growth is assessed, allowing for asymmetric responses to shocks. A nonlinear framework is developed based on a smooth transition model for which the effects of shocks can vary across business cycles when financial indicators modify both the endogenous and state variables. Global financial variables are shown to significantly affect real growth in the Euro area, particularly during periods of recession. Changes in stock market index and yield slope have asymmetric effects on real growth. In recessionary periods, the slope of the US yield curve does not have a significant impact on growth in the Euro area.     

Macroeconomic transitions and the transmission mechanism: Evidence from Turkey

This paper investigates changes to the macroeconomic transmission mechanism in Turkey following a major reform of monetary policy in the early 2000s. We use a Threshold VAR (TVAR) framework to test for and then estimate a model with endogenous transitions between regimes. We detect two regimes, with a clear transition between them in 2003–4. The pre-reform regime is characterized by high inflation, passive monetary policy and persistent responses to shocks. The post-reform regime is characterized by low inflation, active and credible monetary policy and markedly less persistent responses to shocks. Using a model that contains sufficient variables to capture diverse transmission mechanisms, working through the real exchange rate, domestic credit and monetary policy, we find evidence of sharp changes in transmission mechanisms. Post-reform, the response of Turkey to macroeconomic shocks has changed to be similar to those in other modern, market-orientated economies.     

Money Market Uncertainty and Retail Interest Rate Fluctuations: A Cross-Country Comparison

Abstract. This paper analyzes empirically the relationship between money market uncertainty and unexpected deviations in retail interest rates in a sample of ten OECD countries. We find that, with the exception of the United States, money market uncertainty has only a modest impact on the conditional volatility of retail interest rates. Even for the United States, we find that the effects of money market uncertainty are spread out over time. Our results also indicate that money market uncertainty tends to be passed on to retail rates to a lesser extent in countries where banking relationships play a substantial role.     

The Number of Bank Relationships of SMEs: A Disaggregated Analysis of Changes in the Swiss Loan Market

This paper investigates changes in the number of bank relationships of small and medium-sized enterprises in Switzerland from 1996 to 2002. It differentiates between overall bank relationships and lending relationships and disaggregates the loan market with respect to firm sizes, industries and banking groups. On average, bank lending declined, and the concentration of lending relationships increased. The changes seem to have been driven by demand and supply for medium-sized firms, but only by supply for micro and small firms. Supply-side reductions resulted from a merger and changes in credit risk management by major banks. We find evidence of increasing specialization of larger banks on transaction lending and of smaller and regional banks on relationship lending.     

The monetary transmission mechanism: Evidence from the industries of five OECD countries

This paper studies the monetary transmission mechanism using disaggregated industry data from five industrialized countries. Our goal is to document the cross-industry heterogeneity of monetary policy effects and relate it to industry characteristics suggested by monetary transmission theories. Sizable and significant cross-industry differences in the effects of monetary policy are found. Such differences swamp the hardly detectable cross-country variability. Sectoral output responses to monetary policy shocks are systematically related to the industry output durability, financing requirements, borrowing capacity and firm size. These findings are consistent with a quantitatively non-negligible role of financial frictions in the monetary transmission.     

A refined consumption-wealth ratio and its role on time-varying consumption risk

This paper takes a deeper look at the measurement of the consumption-wealth ratio and analyzes its ability to capture variations in expected future stock returns. I find evidence of stock return predictability by taking a different approach than predictive regressions.     

What broad banks do, and markets don’t: Cross-subsidization

We show that interbank markets are a poor substitute for “broad” banks that operate across regions or sectors. In the presence of regional or sectoral asset and liquidity shocks, interbank markets can distribute liquidity efficiently, but fail to respond efficiently to asset shocks. Broad banks can condition on the joint distribution of both shocks and, hence, achieve an efficient internal allocation of capital. This allocation involves the cross-subsidization of loans across regions or sectors. Compared to regional banks that are linked through well-functioning interbank markets, broad banks lead to higher levels of aggregate investment, higher output, and less fluctuations within regions. However, broad banks generate endogenously aggregate uncertainty.     

Bank regulation and supervision and its welfare implications

This study provides a general equilibrium model to explore the welfare implications of bank regulation and supervision (RS). The model supports the basic expectations regarding the positive effects of RS on the growth rate, output, credit, investment, wages and profits; and its negative effects on the interest rate. In addition, RS is observed to lead to a convergence effect. Furthermore, it is observed that the decision of banks to monitor and charge differentiated interest rates to firms depends on the distribution of firm-specific moral hazard rates; bank monitoring increases profits as the distribution of producer type improves.     

Do Bank Capital and Liquidity Affect Real Economic Activity in the Long Run? A VECM Analysis for the US

This paper analyses the long‐term economic costs of the new regulatory standards (the so‐called Basel III reform) for the US. Using a Vector Error Correction Model that estimates long‐run relationships among a small set of macro‐variables over the period 1994–2008, it shows that tighter capital and liquidity requirements have negative (but rather limited) effects on the level of long‐run steady‐state output and more sizeable effects on banks’ return on equity. The economic costs are considerably below the estimated positive benefit that the reform should have by reducing the probability of banking crises and the associated banking losses ( BCBS, 2010b ).     

Maturity mismatch and financial crises: Evidence from emerging market corporations

Substantial attention has been paid in recent years to the risk of maturity mismatch in emerging markets. Although this risk is microeconomic in nature, the evidence advanced thus far has taken the form of macro correlations. We evaluate this mechanism empirically at the micro level by using a database of over 3000 publicly listed firms from fifteen emerging markets. We measure the risk of maturity mismatch by estimating, at the firm level, the effect on investment of the interaction of short-term exposure and aggregate capital flight. This effect is (statistically) zero, contrary to the prediction of the maturity-mismatch hypothesis. This conclusion is robust to using a variety of different estimators, alternative measures of capital flows, and controls for devaluation effects and access to international capital. We do find evidence that short-term-exposed firms pay higher financing costs, and have lower equity valuations, but not that this reduction in net worth translates into a drop in investment or sales.     

Non-linear causality between the stock and real estate markets of Western European countries: Evidence from rank tests

Using the non-parametric rank tests proposed by Breitung (2001), we set out in this study to determine whether any non-linear long-run equilibrium relationship exists between the stock and real estate markets of Western European countries. We go on to adopt the threshold error-correction model (TECM) to determine whether a similar relationship is discernible possibly non-linear functions of the log-price of these two markets. The findings clearly point to the existence of long-run unidirectional and bidirectional causality between the real estate market and the stock market in regions both above and below the threshold level. Finally, we find the existence of both wealth and credit price effects in the real estate markets and stock markets of Western European countries, which thereby offer financial institutions and individual investors in their construction of long-term investment portfolios within these two asset markets.     

Macroeconomic fluctuations: Demand or supply, permanent or temporary?

We use generalized method of moments to estimate a rational expectations aggregate demand/aggregate supply macroeconomic model for five European economies and the United States. Our aim is to examine whether supply or demand shocks have predominated in these economies during the post-war era, and whether shocks of either type have been primarily temporary or permanent in nature. We find that permanent or temporary demand shocks have been the dominant source of variance in output growth in all six countries, but there is a less consistent pattern for inflation. Permanent supply shocks had the dominant influence on autocorrelations.     

Macroeconomic forecasting in the Euro area: Country specific versus area-wide information

This paper compares several time series methods for short-run forecasting of Euro-wide inflation and real activity using data from 1982 to 1997. Forecasts are constructed from univariate autoregressions, vector autoregressions, single equation models that include Euro-wide and US aggregates, and large-model methods in which forecasts are based on estimates of common dynamic factors. Aggregate Euro-wide forecasts are constructed from models that utilize only aggregate Euro-wide variables and by aggregating country-specific models. The results suggest that forecasts constructed by aggregating the country-specific models are more accurate than forecasts constructed using the aggregate data.     

Macroeconomic dynamics in Macedonia and Slovakia: Structural estimation and comparison

This paper estimates a structural macroeconomic model using data for Macedonia and Slovakia to characterize possible challenges Macedonia can face concerning macroeconomic stabilization during its transition process. A comparison of the estimated model parameters suggests that, in Slovakia, the output gap is less sensitive to real interest rate movements and prices experience greater inertia. The estimated monetary policy reaction functions show Macedonia and Slovakia as inflation targeters, with Macedonia as the more conservative one, despite its officially applied exchange rate targeting regime. The differences in the estimated parameters imply differing transmission mechanisms for Macedonia and Slovakia. Consequently, the variance of domestic variables in Slovakia is most influenced by monetary policy shocks, while there is no single dominating shock explaining the volatility of Macedonia's macroeconomic variables. The exchange rate shock, the monetary policy shock and the demand shock are jointly important in determining the volatility of Macedonia's variables. The model simulations indicate that Macedonia experiences lower output gap and inflation volatility than Slovakia. This comes, nevertheless, at the cost of higher interest rate and real exchange rate volatility in Macedonia, which could be an indication of more volatile financial markets with possible negative implications for financial stability.
