Late cutaneous schistosomiasis representing an isolated skin manifestation of Schistosoma mansoni infection

Ectopic late cutaneous schistosomiasis is usually preceded or accompanied by visceral schistosomiasis infection. Our patient presented the very rare case of late cutaneous schistosomiasis as an isolated skin manifestation. Perigenital lesions occurred 1 year after contact with infested water. Identification of the few eggs remaining in the late lesion among the dense cellular infiltrate was difficult. Electron-microscopic studies clearly demonstrated the characteristic eggshell ultrastructure. Copyright (C) 2000 S. Karger AG, Basel

Pricing of bonds and equity when the zero lower bound is relevant

This paper investigates the joint dynamics of nominal bond yields, real bond yields and dividend yields from the 80s up to the aftermath of the financial crisis by mapping them on a set of macro factors. It builds on an existing discrete time affine Gaussian model of the term structure model of nominal bonds, real bonds and equity and extends it by three important innovations. Firstly, allowing for structural shifts in inflation expectations. Secondly, accounting for the relevance of the zero lower bound in the period after 2008 by modelling a so-called shadow rate and deriving asset prices by explicitly considering the zero lower bound. Finally, calculating the standard errors to correctly capture the multi-step nature of the estimation process, which results in substantially larger standard errors than previously reported for the model. We achieve statistically signicant risk premia by imposing restrictions on the matrix of risk premia. Taken together, these modifications allow to better model asset prices also during the financial crisis and the ensuing economic environment of sluggish growth, low inflation rates, interest rates close to zero and quantitative easing

Slippery slopes of stress: ordered failure events in German banking

Outright bank failures without prior indication of financial instability are very rare. Supervisory authorities monitor banks constantly. Thus, they usually obtain early warning signals that precede ultimate failure and, in fact, banks can be regarded as troubled to varying degrees before outright closure. But to our knowledge virtually all studies that predict bank failures neglect the ordinal nature of bank distress. Exploiting the distress database of the Deutsche Bundesbank we distinguish four different distress events that banks experience. Only the worst entails a bank to exit the market. Weaker orders of distress are, first, compulsory notifications of the authorities about potential problems, second, corrective actions such as warnings and hearings and, third, actions by banking pillar's insurance schemes. Since the four categories of hazard functions are not proportional, we specify a generalized ordered logit model to estimate the respective probabilities of distress simultaneously. Our model estimates each set of probabilities with high accuracy and confirms, first, the necessity to account for different kinds of distress events and, second, the violation of the proportional odds assumption implicit in most limited dependent analyses of bank failure. --Bank,failure,distress,generalized ordered logit

Income diversification in the German banking industry

In the last few years it has been possible to observe decreasing interest margins for German universal banks. At the same time, institutions increasingly moved part of their business from interest to fee-earning activities. This study analyzes the determinants of non-interest income and its impact on financial performance and the risk profile of German banks between 1995 and 2007. We find empirical evidence that for all German universal banks risk-adjusted returns on equity and total assets are positively affected by higher fee income activities. Additionally, for commercial banks we show that a strong engagement in fee-generating activities goes along with higher risk. In order to analyze possible cross-subsidization effects between interest and fee business we also examine how banks' expansion in fee-based services has affected their interest margin. For savings and commercial banks we find that institutions with a strong focus on fee business charge lower interest margins when credit risk is controlled. --Income diversification,interest income,fee income,interest margin,two-stage least squares estimator

Bank risk taking and liquidity creation following regulatory interventions and capital support

During times of bank distress, authorities often engage in regulatory interventions and provide capital support to reduce bank risk taking. An unintended effect of such actions may be a reduction in bank liquidity creation, with possible adverse consequences for the economy as a whole. This paper tests hypotheses regarding the effects of regulatory interventions and capital support on bank risk taking and liquidity creation using a unique dataset over the period 1999-2009. We find that both types of actions are generally associated with statistically significant reductions in risk taking and liquidity creation in the short run and long run. While the effects of regulatory interventions are also economically significant, the effects of capital support are only economically significant in the long run. Thus, both types of actions have important intended and unintended consequences with implications for policymakers.risk taking;liquidity creation;bank distress;regulatory interventions;capital support

Monetary policy and bank distress: an integrated micro-macro approach

Evidence on the interdependency between monetary policy and the state of the banking system is scarce. We suggest an integrated micro-macro approach with two core virtues. First, we measure the probability of bank distress directly at the bank level. Second, we integrate a microeconomic hazard model for bank distress and a standard macroeconomic model. The advantage of this approach is to incorporate micro information, to allow for non-linearities and to permit general feedback effects between bank distress and the real economy. We base the analysis on German bank and macro data between 1995 and 2004. Our results confirm the existence of a relationship between monetary policy and bank distress. A monetary contraction increases the mean probability of distress. This effect disappears when neglecting micro effects, underlining the crucial importance of the former. Distress responses are economically most significant for weak distress events and at times when capitalization is low. --Stress testing,bank distress,monetary policy

Determinants for using visible reserves in German banks: an empirical study

The German Commercial Code (HGB) allows banks to build visible reserves for general banking risks according to section 340g HGB. These GBR reserves may, in addition to their risk provisioning function, be used to enhance capital endowment, for internal financing, signaling or earnings management purposes. We analyze financial statements of German banks for the period from 1995 through 2007 to reveal specific patterns in the use of GBR reserves. Our empirical investigation is based on a large, unbalanced panel of German banks including 32,023 bank-year observations. We see an increase in the use of GBR reserves over time. Furthermore, we can say that GBR reserves are primarily used by large banks, banks with comparatively low regulatory capital endowment, as well as those with lower risks. Furthermore, GBR reserves are used by fairly profitable banks, those reporting according to international financial reporting standards in addition to HGB, and banks which are not thrifts or cooperative banks. Finally, we find that banks which make use of hidden reserves according to section 340f HGB also tend to hold GBR reserves. We explain our findings with regulatory factors and existing information asymmetries as well as banks' size and ownership structure. --Bank regulation,informational asymmetries,risk provisioning,visible reserves,hidden reserves

Making sense of the EU wide stress test: a comparison with the SRISK approach

We analyse the SRISK measure with respect to its usage as a benchmark for the ECB/EBA 2014 stress test. By regressing the ECB/EBA stress test impact and the SRISK stress impact on a set of factors that are commonly associated with bank credit losses and bank vulnerability, we find that the ECB/EBA stress impact is consistent with findings in the literature on credit losses. In contrast, the SRISK measure bears much less relation to these factors; it is largely driven by the banks’ leverage ratio. These differences are deeply rooted in the construction of the respective measures. With its focus on losses to bank equity, the SRISK measure appears poorly matched as a benchmark for the supervisory stress test in Europe, which is centred on losses to banks’ total assets

Cross-border transmission of emergency liquidity

We show that emergency liquidity provision by the Federal Reserve transmitted to non-U.S. banking markets. Based on manually collected holding company structures of international banks, we can identify banks in Germany with access to U.S. facilities via internal capital markets. Using proprietary interest rate data reported to the German central bank, we compare lending and borrowing rates of banks with and without such access. U.S. liquidity shocks cause a significant decrease in the short-term funding costs of German banks with access. Short-term loan rates charged to German corporates also decline, albeit with lags between two and four months. These spillover effects of U.S. monetary policy are confined to short-term rates
