The paper proposes a structure of a composite Index of Local Government Employees Satisfaction (ESI) in Poland. The index provides a based on four sub-indices synthetic assessment of the level of employee satisfaction with the employment in local government offices. The sub-indices have been constructed using an exploratory factor analysis with the VARIMAX one. The ESI and sub-indices values have been normalized in the range of [0–100%], wherein higher ESI values indicate higher employee satisfaction. The proposed approach is used to assess the level of employee satisfaction with the employment in some local government units in the West Pomerania province. The analysis was based on the results of the measurements made in 2009–2010 by comparing the results of two groups of employees separated on the basis of a criterion of their place of employment.

This study examined the effect of government expenditure on its disaggregated level on economic growth in a sample of 20 sub-Saharan African Countries over the period of 1980-2010 in a dynamic panel data model. The result from Generalised Method of Moments (GMM) revealed an inverse relationship between productive government expenditure and economic growth in sub-Sahara Africa. Also, productive government expenditures were not actually productive most especially when financed by non-distortonary government tax revenue in sub-Saharan African countries. The study concluded that the productive government expenditure and its corresponding source of the mode of financing were counterproductive for economic performance in the African countries.

A new application of fuzzy sets theory in social and economic research is a fuzzy measurement of respondents' opinions. In the subject literature fuzzy rating scales or fuzzy conversion scales are being applied. In this second case, a key stage is a choice of such parameters' values of fuzzy numbers which will best illustrate the perception of linguistic values constituting points of measurement scales. In the construction of fuzzy conversion scales the item response theory models can find an application. The transformation method of verbal categories to the form of triangular fuzzy numbers with the application of rating scale model was proposed in this article. Usefulness of a suggested approach was introduced on the basis of the analysis of selected research results on inhabitants' quality of life in one of the Lower Silesian Voivodship districts. The analysis results showed big ambiguity of particular verbal categories and, in consequence, the validity of fuzzy conversion scales application.

Since the deterministic chaos appeared in the literature, we have observed a huge increase in interest in nonlinear dynamic systems theory among researchers, which has led to the creation of new methods of time series prediction, e.g. the largest Lyapunov exponent method and the nearest neighbor method. Real time series are usually disturbed by random noise, which can complicate the problem of forecasting of time series. Since the presence of noise in the data can significantly affect the quality of forecasts, the aim of the paper will be to evaluate the accuracy of predicting the time series filtered using the nearest neighbor method. The test will be conducted on the basis of selected financial time series.

The paper examines the development of the Polish economy as well as the economies of selected countries in the period from 2001 to 2012. For that purpose, models based on the GDP growth in particular countries were built. A comparative analysis of the development of economies in the countries concerned (the United Kingdom, Belgium, Denmark, France, Poland, the Netherlands), based on a specially built full-factor multivariate GARCH model, is presented. The theory of the construction of a full-factor multivariate GARCH model and its estimation method are discussed. In the paper, a multivariate GARCH model where the covariance matrix is always positive, definite and the number of parameters is relatively small compared to other multivariate models is proposed. The causality of the impact that economies exert on one another is examined and the occurrence of the contagion effect is verified by means of the Forbes and Rigobon test.
