In the paper some prominent features of a modern financial system are studied using the model of leverage dynamics. Asset securitization is considered as a major factor increasing aggregate debt and hence systems uncertainty and instability. A simple macrofinancial model includes a logistic equation of leverage dynamics that reveals origins of a financial bubble, thus corresponding closely to the Minsky financial instability hypothesis. Using ROA, ROE, and the interest rate as parameters, the model provides wide spectrum of leverage and default probability trajectories for the short and long run.
We aim to discover the relationship between market discipline and banking system transparency using the cross-country data (1990-2003) with Nier index and index based on World Bank surveys' data. We show that measures aimed to increase transparency, not being accompanied with requirements related to information availability and/or interpretability, may be not efficient in reaching the goal of market discipline stimulation.
