Knowledge that Transforms

Against a background of far-reaching structural change in the banking sector, this article reviews the recent academic literature on developments in European banking. European banking markets have become increasingly integrated in recent years, but barriers to full integration, especially in retail banking, still remain. European integration has possible implications for systemic risk, and poses various challenges for the current supervisory framework. The banks’ responses to the changing competitive environment include the pursuit of strategies of diversification, vertical product differentiation and consolidation. European integration has implications for competition in banking markets, for the nature of long-term borrower-lender relationships, and for the relationships between ownership structure, technological change and bank efficiency. The article concludes by reviewing recent literature on the credit channel in the monetary transmission mechanism, and interest rate pass-through.

This paper analyzes individual bidding data of the longer term refinancing operations (LTROs) of the European Central Bank. We investigate how banks’ bidding behavior is related to a series of exogenous variables including collateral costs, interest rate expectations, market volatility and to individual bank characteristics like country of origin, size, and experience. A specific feature of these auctions is that the number and composition of bidders varies over time. Therefore, we estimate panel sample selection models to control for a bank’s endogenous participation decision. We find that bidding strategies depend on the banks’ attributes. Yet, different bidding behavior generally does not translate into differences concerning bidder success. There is evidence for the winner’s curse effect in LTROs indicating a common value component in banks’ demand for longer term refinancing.

Most of the theoretical and empirical literature on bank margins has dealt solely with interest margins. Applying the seminal Ho–Saunders model (JFQA, 1981) to a multi-output framework, we show that the relationship between bank margins and market power varies significantly across bank specializations. In this context, European banks are a better laboratory than US banks, since they have generally enjoyed a more flexible regulatory environment in which to provide a wider range of services. Using accounting margins and New Empirical Industrial Organization margins, we find that market power increases as output becomes more diversified towards non-traditional activities in European banking.

Motivated by the liberalisation and harmonisation of financial systems in Europe, we investigate whether the observed shift into non-interest income activities improves performance of small European credit institutions. Using a sample of 755 small banks for the period 1997–2003, we find no direct diversification benefits within and across business lines and an inverse association between non-interest income and bank performance. Our findings are robust to a set of sensitivity analyses using alternative samples and controlling for the regulatory environment. Furthermore, the results provide circumstantial evidence for the presence of economies of scale. The absence of benefits of diversification confirms findings for other banking markets and suggests small European banks enter lines of business where they currently lack expertise and experience. These results have implications for bank supervisors, regulators and bank managers.

This paper uses a new dataset to reassess the relationship between bank ownership and bank performance, providing separate estimations for developing and industrial countries. It finds that state-owned banks located in developing countries tend to have lower profitability and higher costs than their private counterparts, and that the opposite is true for foreign-owned banks. The paper finds no strong correlation between ownership and performance for banks located in industrial countries. Next, in order to test whether the differential in performance between public and private banks is driven by political considerations, the paper checks whether this differential widens during election years; it finds strong support for this hypothesis.

Since empirical research has demonstrated that a sound financial system drives economic growth and the reverse causality alone is not causing this relationship, one can well extend this causal relationship to a global financial system and also argue that those factors that are limiting stronger economic growth and financial globalisation are partly related to deficiencies of the current global financial system. In the same way that some studies have argued for the significance of high quality national institutions as a way of addressing some of the national social and economic bottlenecks and also as a way of creating the right environment for sustained economic growth and integration into the global markets, high quality international institutions with adequate mandates and effective executive power can also influence the process of regional and global financial integration. These international institutions can accelerate the process of national institutional reforms. The paper argues that a number of financial barriers limiting financial globalisation have in essence international, regional and national components and hence without a globally coordinated strategy and framework to have parallel reforms at three levels, the limits to financial globalisation may remain for the foreseeable future.

This paper shows how a mean variance criterion can be applied to a multi period setting in order to obtain efficient portfolios in an asset and liability context. The optimization model allows for rebalancing activities, transaction costs, stochastic volatilities for both assets and liabilities. Furthermore, a general framework for the projection of pension fund liabilities as well as for the generation of asset returns is given. In a further step the dynamics of the liability maturity structure is modeled as customized index, whose volatility and correlation with asset returns become integral components of the applied regime switching approach. The numerical results illustrate the diversification of the assets and its risk return pattern in dependency of the liability dynamics.

A contentious debate exists over whether executives possess market timing skills when announcing certain corporate transactions. Pseudo-market timing, however, has recently emerged as an important alternative hypothesis as to why the appearance of timing might be evident when, in fact, none exists. We reconsider this debate in the context of share repurchases. Consistent with prior studies, we also report evidence of abnormal stock performance following buyback announcements. Pseudo-market timing, however, does not appear to be a viable explanation. Our results are more consistent with the notion that managers possess timing ability, at least in the context of share repurchases.

The term structure of interest rates is often summarized using a handful of yield factors that capture shifts in the shape of the yield curve. In this paper, we develop a comprehensive model for volatility dynamics in the level, slope, and curvature of the yield curve that simultaneously includes level and GARCH effects along with regime shifts. We show that the level of the short rate is useful in modeling the volatility of the three yield factors and that there are significant GARCH effects present even after including a level effect. Further, we find that allowing for regime shifts in the factor volatilities dramatically improves the model’s fit and strengthens the level effect. We also show that a regime-switching model with level and GARCH effects provides the best out-of-sample forecasting performance of yield volatility. We argue that the auxiliary models often used to estimate term structure models with simulation-based estimation techniques should be consistent with the main features of the yield curve that are identified by our model.

This paper describes the first thorough empirical analysis of the pricing of leverage products in the German retail market. These mainly exchange-traded products with an impressive trading volume are frequently advertised as long and short futures contracts, although they are theoretically equivalent to one-sided barrier options. Issuers’ daily quotes for stock index products are compared to (i) theoretical values derived from the prices of Eurex options and to (ii) boundaries obtained from semi-static superhedging strategies. For the vast majority of products, bid and ask quotes significantly exceed both theoretical values and upper hedging boundaries, thus providing almost risk-free profits for the issuers.
