This book contains a selection of the papers presented at the 24th Meeting of the Euro Working Group on Financial Modelling held in Valencia, Spain, on April 8-10, 1.999. The Meeting took place in the Bancaja Cultural Center, a nice palace of the XIX century, located in the center of the city. Traditionally, members of the Euro Working Group on Financial Mod­ elling meet twice a year, hosted by different active groups in successions. The year 1999 was very special for us because the University of Valencia celebrates its fifth century. The Meeting was very well attended and of high quality. More than 90 participants, coming from 20 different countries debated 46 communications in regular sessions. The opening lecture was given by Prof. H. White, from the University of California, San Diego. The topics discussed were classified in nine sessions: Financial Theory, Financial Time Series, Risk Analysis, Portfolio Analysis, Financial Institu­ tions, Microstructures Market and Corporate Finance, Methods in Finance, Models in Finance and Derivatives. The papers collected in this volume provide a representative but not com­ plete sample of the fields where the members of the working group develop their scientific activity. The papers are a sample of this activity, and consist of theoretical papers as well as empirical ones.
