The authors use a variance ratio test to test the weak form of market efficiency as regards capital markets in the Czech Republic, Slovakia, Hungary, Poland, and in the United States. Market efficiency was tested using weekly and monthly values of relevant market indices in a period from 1993...

Volatility of the financial time series belongs to the crucial estimated parameters in finance (e.g. in risk management, derivative pricing). It is well known, that volatility varies in time, so that new approaches of volatility modeling have appeared. In this paper two models of the conditional...

The paper deals with the impact of new information on the fixed income market. We expect this to be the first study covering such a topic in Central European markets. We prepared a model of a market reaction and found out that the market is not significantly driven by new macroeconomic figures....

Effectiveness of actual monetary policy depends on the ability of central banks to stabilize the fluctuations of overnight interest rates around their official policy rate. To ensure the functionality of the stabilization mechanism needs the successful balancing between bank's demand for...
