The Importance of Estimation Uncertainty in a Multi-Rating Class Loan Portfolio

IWH Discussion Papers,
Nr. 11,
2011
Abstract
This article seeks to make an assessment of estimation uncertainty in a multi-rating class loan portfolio. Relationships are established between estimation uncertainty and parameters such as probability of default, intra- and inter-rating class correlation, degree of inhomogeneity, number of rating classes used, number of debtors and number of historical periods used for parameter estimations. In addition, by using an exemplary portfolio based on Moody’s ratings, it becomes clear that estimation uncertainty does indeed have an effect on interest rates.

What Might Central Banks Lose or Gain in Case of Euro Adoption – A GARCH-Analysis of Money Market Rates for Sweden, Denmark and the UK
Herbert S. Buscher, Hubert Gabrisch
IWH Discussion Papers,
Nr. 9,
2011
Abstract
This study deals with the question whether the central banks of Sweden, Denmark and the UK can really influence short-term money markets and thus, would lose this influence in case of Euro adoption. We use a GARCH-M-GED model with daily money market rates. The model reveals the co-movement between the Euribor and the shortterm interest rates in these three countries. A high degree of co-movement might be seen as an argument for a weak impact of the central bank on its money markets. But this argument might only hold for tranquil times. Our approach reveals, in addition, whether there is a specific reaction of the money markets in turbulent times. Our finding is that the policy of the European Central Bank (ECB) has indeed a significant impact on the three money market rates, and there is no specific benefit for these countries to stay outside the Euro area. However, the GARCH-M-GED model further reveals risk divergence and unstable volatilities of risk in the case of adverse monetary shocks to the economy for Sweden and Denmark, compared to the Euro area. We conclude that the danger of adverse monetary developments cannot be addressed by a common monetary
policy for these both countries, and this can be seen as an argument to stay outside the Euro area.

Inflation Expectations: Does the Market Beat Professional Forecasts?
Makram El-Shagi
North American Journal of Economics and Finance,
Nr. 3,
2011
Abstract
The present paper compares expected inflation to (econometric) inflation forecasts based on a number of forecasting techniques from the literature using a panel of ten industrialized countries during the period of 1988 to 2007. To capture expected inflation, we develop a recursive filtering algorithm which extracts unexpected inflation from real interest rate data, even in the presence of diverse risks and a potential Mundell-Tobin-effect.
The extracted unexpected inflation is compared to the forecasting errors of ten
econometric forecasts. Beside the standard AR(p) and ARMA(1,1) models, which
are known to perform best on average, we also employ several Phillips curve based approaches, VAR, dynamic factor models and two simple model avering approaches.

Exchange Rate Expectations and the Pricing of Chinese Cross-listed Stocks
Stefan Eichler
Journal of Banking and Finance,
Nr. 2,
2011
Abstract
I show that the price discounts of Chinese cross-listed stocks (American Depositary Receipts (ADRs) and H-shares) to their underlying A-shares indicate the expected yuan/US dollar exchange rate. The forecasting models reveal that ADR and H-share discounts predict exchange rate changes more accurately than the random walk and forward exchange rates, particularly at long forecast horizons. Using panel estimations, I find that ADR and H-share investors form their exchange rate expectations according to standard exchange rate theories such as the Harrod–Balassa–Samuelson effect, the risk of competitive devaluations, relative purchasing power parity, uncovered interest rate parity, and the risk of currency crisis.

Interest Rate Convergence in the Euro-Candidate Countries: Volatility Dynamics of Sovereign Bond Yields
Hubert Gabrisch, Lucjan T. Orlowski
Emerging Markets Finance and Trade,
2010
Abstract
We argue that a “static“ specification of the Maastricht criterion for long-term bond yields is not conducive to assessing stability of financial systems in euro-candidate countries. Instead, we advocate a dynamic approach to assessing interest rate convergence to a common currency that is based on the analysis of financial system stability. Accordingly, we empirically test volatility dynamics of the ten-year sovereign bond yields of the 2004 EU accession countries in relation to the eurozone yields during the January 2, 2001-January 22, 2009, sample period. Our results show a varied degree of the relationship between domestic and eurozone sovereign bond yields, the most pronounced for the Czech Republic, Slovenia, and Poland, and weaker for Hungary and Slovakia. We find some divergence of relative bond yields since the EU accession.

Works Councils and Separations: Voice, Monopoly, and Insurance Effects
Boris Hirsch, Thorsten Schank, Claus Schnabel
Industrial Relations,
Nr. 4,
2010
Abstract
Using a large linked employer–employee data set for Germany, we find that the existence of a works council is associated with a lower separation rate to employment, in particular for workers with low tenure. While works council monopoly effects show up in all specifications, clear voice effects are only visible for low tenured workers. Works councils also reduce separations to nonemployment, and this impact is more pronounced for men. Insurance effects only show up for workers with tenure of more than 2 years. Our results indicate that works councils to some extent represent the interests of a specific clientele.

International Bank Portfolios: Short- and Long-run Responses to Macroeconomic Conditions
S. Blank, Claudia M. Buch
Review of International Economics,
Nr. 2,
2010
Abstract
International bank portfolios constitute a large component of international country portfolios. Yet, banks’ response to international macroeconomic conditions remains largely unexplored.We use a novel dataset on banks’ international portfolios to answer three questions. First, what are the long-run determinants of banks’ international portfolios? Second, how do banks’ international portfolios adjust to short-run macroeconomic developments? Third, does the speed of adjustment change with the degree of financial integration?We find that, in the long-run, market size has a positive impact on foreign assets and liabilities. An increase in the interest differential between the home and the foreign economy lowers foreign assets and increases foreign liabilities. Foreign trade has a positive impact on international bank portfolios, which is independent from the effect of other macroeconomic variables. Short-run dynamics show heterogeneity across countries, but these dynamics can partly be explained with gravity-type variables.
