In this article is studied hypothesis, that every period (time interval) before financial crisis is distinguished by co-movement of several variables. The study is based on monthly data (that means no quarterly data, like portfolio investment, were used). This hypothesis, tested with vector...

We analyze effect of intraday information flow in three emerging EU stock markets-the Czech Republic, Hungary, and Poland. We use five-minute intraday data on stock market index returns and 15 types of EU and U.S. macroeconomic announcements during 2004-2007. We measure each announcement as its...

The regression model with categorical dependent variable is a natural generalization of the model with binary dependent variable. It is based on the use of baseline logits. For its building and for the evaluation of its quality, analogous procedures to the case of binary dependent variable are...

The world raw material market has undergone a great change in the recent years. One of the essential reasons is the rapid economic growth of many former developing countries such as China, India, Indonesia, Brazil, Vietnam, etc. These countries were historically and typically producers and...

The article analyses reasons for state regulation, and deals with present regulatory projects aimed at ensuring increased stability of financial, or more precisely, insurance markets, especially with respect to securing an adequate level of consumer protection and lowering information asymmetry....

This article takes focus on the main basic elements of panel data analysis, fixed effects and random effects models, dynamic panel data models. The last part of this article is about possibilities of testing panel data unit roots with a notice about the usage of the application software and...

The essay is the contribution to analysis of the determination and addition of the utility. There are shown the contradictions between quantitative and qualitative thinking about the problems of utility for the individual and for multitude people in society. In this interpretation rised also the...

Probability modeling may be approached in several principally different ways. One of such possibilities to achieve the aim is approximation of empirical distribution by means of an already known distribution (i.e. a parametric model). This paper focuses first on description of methods that may...

Robust design reduces excessive process variation. Identification of dispersion effects plays an important role in it. Two main approaches are used to analyze the experiment where levels of noise factors are changed on purpose. Either the function of sample variance computed from replications...
