The significance of credit risk models has increased with the introduction of new Basel accord known as Basel II. The aim of this study is default rate modeling. This thesis follows the two possible approaches of a macro credit risk modeling. First, empirical models are investigated. Second, a latent factor model based on Merton's idea is introduced. Both of these models are derived from individual default probability models. We employed data over the time period from 1988 to 2003 of the Finnish economy in the first part of this thesis. Time series of bankruptcy and firm's numbers were used. Aggregate data for whole economy as well as industry specific data were available. First, linear vector autoregressive models was used in case of dynamic empirical model. We examined how significant macroeconomic indicators determined the default rate in the whole economy and in the industry specific sector. However these models cannot provide microeconomic foundation as latent factor models. We employed a one- factor model in our estimation although, multi-factor models were also considered. A one-factor model was estimated using disaggregated industrial data. This estimation can help understand relation between credit risk and macroeconomic indicators. Obtained results were used in the second part of this...

In my thesis I focus on regulatory risk affecting financial markets effectiveness. I describe specifics of financial markets regulation in Czech Republic and in the World, particularly the development of bank capital adequacy regulation. Further I discuss practical problems connected with implementation of New Basel Accord (Basel II), but also its advantages arising for banks. Last part of my paper is devoted to the evaluation of expected impact of the new rules on the effectiveness of financial markets and to the consideration of future perspectives of financial system regulation.

This thesis deals with measuring and managing operational risk in the context of Basel II. The main goal of this work is to analyze different methods for quantification of operational risk and evaluate which method is the most suitable according to its nature. This work outlines the milestones of Basel II, its goals and tools. It defines the operational risk and clarifies its categorization. This paper also concentrates on Basel Committee's requirements concerning the quantification methods and it discusses related problems. This work examines the widespread operational risk measurement approaches. Final part is devoted to operational risk management process. Powered by TCPDF (www.tcpdf.org)
