Wie weit tr?gt der Bachelor? Zum aktuellen Stand der Bologna-Reform in Deutschland

The Federal Ministry of Education and Research (BMBF) states that the Bologna Accords have been successfully implemented in Germany. However, empirical studies show that this can be very questionable. The aim to reduce the average study duration has not been accomplished mainly due to a higher than expected conversion rate from Bachelor to Master level. Although the Bachelor’s degree is broadly accepted among future employers, the majority of students do not trust the career opportunities with a Bachelor’s degree only and prefer to undertake a Master’s degree. In fact, the starting salaries for Bachelor’s degree graduates, especially from universities, are significantly lower than for the graduates holding a Diploma or a Master’s degree.     

Polynomial processes and their applications to mathematical finance

We introduce a class of Markov processes, called m-polynomial, for which the calculation of (mixed) moments up to order m only requires the computation of matrix exponentials. This class contains affine processes, processes with quadratic diffusion coefficients, as well as Lévy-driven SDEs with affine vector fields. Thus, many popular models such as exponential Lévy models or affine models are covered by this setting. The applications range from statistical GMM estimation procedures to new techniques for option pricing and hedging. For instance, the efficient and easy computation of moments can be used for variance reduction techniques in Monte Carlo methods.     

A general HJM framework for multiple yield curve modelling

We propose a general framework for modelling multiple yield curves which have emerged after the last financial crisis. In a general semimartingale setting, we provide an HJM approach to model the term structure of multiplicative spreads between FRA rates and simply compounded OIS risk-free forward rates. We derive an HJM drift and consistency condition ensuring absence of arbitrage and, in addition, we show how to construct models such that multiplicative spreads are greater than one and ordered with respect to the tenor’s length. When the driving semimartingale is an affine process, we obtain a flexible and tractable Markovian structure. Finally, we show that the proposed framework allows unifying and extending several recent approaches to multiple yield curve modelling.     

A new exchange rate mechanism for the Euro age

Only a limited number of countries will participate in the single currency area at its formation on January 1st, 1999. A new link between the currencies participating in the Euro zone and those unable or unwilling to do so must therefore be created. A new EMS, with the Euro as its anchor currency, must be installed to ease the path into EMU for those countries that wish to join at a later date.     

A new chance for trade and investment

International investment flows have increased rapidly with the growing globalization of markets and production. These flows will be of greatest benefit to the world economy as a whole if they can be based on a transparent and predictable system of generally recognized rules. What strategy should the EU adopt to help create those rules? *** DIRECT SUPPORT *** A02GP103 00002     

Affine multiple yield curve models

We provide a general and tractable framework under which all multiple yield curve modeling approaches based on affine processes, be it short rate, Libor market, or Heath–Jarrow–Morton modeling, can be consolidated. We model a numéraire process and multiplicative spreads between Libor rates and simply compounded overnight indexed swap rates as functions of an underlying affine process. Besides allowing for ordered spreads and an exact fit to the initially observed term structures, this general framework leads to tractable valuation formulas for caplets and swaptions and embeds all existing multicurve affine models. The proposed approach also gives rise to new developments, such as a short rate type model driven by a Wishart process, for which we derive a closed‐form pricing formula for caplets. The empirical performance of two specifications of our framework is illustrated by calibration to market data.     

Europe prepares for a single financial market

A single market in financial services has long been an objective of the European Union. In 1999, the Commission launched the Financial Services Action Plan (FSAP), an ambitious programme to integrate capital markets by 2005. This article gives an overview of the progress made so far and the tasks which still need to be tackled.
