The development of computer sciences and telecommunication together with legislation changes caused the globalization of capital markets and the increase of their role in the economy. To measure the level of the development of capital markets it is necessary to take into account several aspects that lead to providing multidimensional analysis. Therefore multivariate statistical methodology can be...
One of the main objectives to be accomplished by the European Union law is to eliminate barriers to the functioning of domestic market and in particular improve the competitiveness of enterprises. The paper addresses issues relating to tax in corporate finance. Canons of taxation are discussed and special emphasis is placed on principles behind formulating fiscal law provisions (including the EU law)...
The paper aimed at identifying the effects of the coincidence of socio-economic status and the advancement of the family life cycle on the savings rate. The multilevel regression model for data from empirical surveys was used. The obtained results allow us to explain how the differentiation of the saving rate that causes a poor fit of LCH models to the observed reality occurs. Ascribed to this differentiation...
The aim of this paper was to analyze the long term impact of the 2007-2009 global financial crisis on the banking sectors of CEE countries, in particular in analyzing the consequences of the crisis on bank stability, efficiency and lending policies. Analyzing bank performance and stability, the paper suggests adding a new analytical tool in analyzing risk-adjusted performance: the Multi Level Performance...
The concept of the quality of consumer products and services is fairly well defined. Although today quality of life, including quality of education and training, is a commonly discussed topic, one has to admit that the evaluation system of educational processes and the quality of work of educational institutions is surprisingly low. At the same time, the modernization processes in the system of universities...
Changes of an economic, social and even political character are consequences of the process of globalisation that has been expanding for several recent decades. Changes in employment structure and thereby in the vision of the labour market are one of the results of this process. Changes of this type have their origins in modern technologies because they transform industrial civilisation into service...
The paper will present the results of the application of the modified additive and multiplicative exponential smoothing models (Brown, Holt and Holt-Winters) in the interpolation and extrapolation forecasting of demand for power energy in the agglomeration A in hour periods, based on time series with systematic gaps. The basis for the construction of forecasts will be time series, from which twelve...
Mobility of students plays a major role in developing creativity, active citizenship and chances of employment − especially in the face of labour market globalization. The article refers to the chosen area of research on students, in the context of determinants of students educational mobility. The purpose of research was to explore determinants of educational mobility, to reveal common features and...
In this paper a multivariate analysis of the subjective perception of quality of life is undertaken. In the analysis methods of a fuzzy set theory are applied. The study is conducted on data from the Social Diagnosis 2013. It includes 16 items relating to the evaluation of satisfaction with particular aspects of life. Each of these items is measured on a 7-grade scale. The item’s categories are converted...
The main aim of the paper is the analysis of application of the reference set consisting of the alternatives near the ideal solution in selected multi-criteria techniques. The comparative overview of ZAPROS, MARS and UTA techniques in the perspective of their usefulness in ill structure decision making problems was made. The theoretical discussion was illustrated by a numerical example that shows...
In this article we investigate the latest developments on life expectancy modeling. We review some mortality projection stochastic models and their assumptions, and assess their impact on projections of future life expectancy for selected countries in the EU. More specifically, using the age- and sex-specific data of 20 countries, we compare the point projection accuracy and bias of six principal...
In this paper, the results of the quantification procedures and the properties of expectations series obtained for two data vintages are compared. The volume index of production sold in manufacturing is defined for end-of-sample and real time data, and evaluated against expectations expressed in business tendency surveys. Empirical analysis shows that (1) there are no statistically significant differences...
This paper examines the effect of Exchange Rate Volatility (ERV) on the aggregate exports of Ukraine during the period of 1990 to 2013 using quarterly data. In the literature, it is found that exchange rate volatility causes a reduction in the overall level of trade. The paper tests this finding for Ukrainian foreign trade in the aforementioned period using the Autoregressive Distributed Lags (ARDL)...
The article concerns the application of selected distributions of extreme values to estimate the risk of occurring of flood danger in Lower Silesia. In the study a daily water level on the Nysa Klodzka River was used, that was gathered in the hydrological station in Bystrzyca Klodzka. From the collected data from the period 1981-2013 biannual maximum water level was selected. Two theoretical distributions:...
Item response theory is considered to be one of the two trends in methodological assessment of the reliability scale. In turn, latent class models can be viewed as a special case of model-based clustering, for heterogenous multivariate discrete data. We used the approach combining item response theory and latent class models to find groups of Polish households’ with similar saving ability levels....
One of important forms of investment in human resources that can bring benefits both to individuals and the society as a whole is education. Raising the level of education, like any other investment, requires incurring costs in order to achieve certain profits. Balance between planned costs and potential benefits associated with the investment project determines the allocation of funds for its implementation...
The aim of the article is to present how to carry out the classical and logistic regression analyses in sample surveys, describing the socio-economic phenomena, to which complex a sample was drawn. The object of the study are households in Poland, surveyed in the household budgets survey, conducted annually by the Central Statistical Office. The essence of the methods analysis of complex samples is...
Regression analysis is perhaps the best known and most widely used method used for the analysis of dependence; that is, for examining the relationship between a set of independent variables (X’s) and a single dependent variable (Y). In general regression, the model is a linear combination of independent variables that corresponds as closely as possible to the dependent variable [Lattin, Carroll, Green...
The aim of the study was to compare, a posteriori, the probabilities (chances) of failure to achieve the level of aspiration (expressed in expected rates of return) on open-end debt investment funds (debt OEF), as well as the rates of return on bank deposits in Poland in light of different investment horizons. The data covered the periods of operation of each individual fund. The values for the probability...
