W artykule przedstawiono propozycję konstrukcji przestrzennej syntetycznej miary rozwoju. Modyfikacja klasycznego miernika polegała na aplikacji elementów macierzy wag przestrzennych do formuły taksonomicznego miernika rozwoju Hellwiga (...). Następnie proponowany miernik zastosowano w badaniu zrównoważonego rozwoju województw w wybranych latach 2000 i 2010. Dokonano porównania, interpretacji i weryfikacji poprawności merytorycznej otrzymanych wyników. (fragment tekstu)

The nature and level of the analyzed variables are not only the result of the passage of time, the structure of the economy and geographical conditions of the region but also the location and the neighborhood of other regions. Until now, an aspect of the spatial interactions in form a matrix of spatial weights, was not included in any of the formula synthetic measure. This paper proposes a taxonomy spatial measure of development which allows simultaneous analyzes in three dimensions as follows: time, section and space. The modification of classical measurement consisted in introduction of the spatial weights matrix elements to the formula of the classical Hellwig development measure (formerly verifying the existence of the phenomenon of spatial autocorrelation on the basis of Moran I statistics). Then, an application of the proposed tool was prepared to study the level of development of Polish regions in 2000 as well as 2010. (original abstract)

Celem artykułu jest analiza przestrzennego zróżnicowania rozwoju ekonomicznego województw i powiatów w latach 2002-2011, z wykorzystaniem taksonomicznych wskaźników rozwoju oraz z uwzględnieniem zależności historyczno-politycznych, terytorialnych (odległość od centrów zarządzania) i gospodarczych, co pozwoliło na poszerzenie oceny i wnioskowania.

The aim of the article is to analyze the spatial differentiation of economic development of voivodships and poviats in the period 2002-2011 using taxonomic indicators. The inference based on historical-political, territorial (distance from the center management) and economic, which allowed for the expansion of and more flexible assessment. Analyses are based on homogeneous characteristics. For measuring were selected statistically stable variables: average salary, number of entities in the REGON registry (per 1000 inhabitants), the unemployment rate and sold production per capita, the gross value of fixed assets and investments. Using diagnostic variables were established indicators of economic development of the various local government units. The result of the work is the ranking voivodships and poviats, taking into account long-term conditions. (original abstract)

Celem artykułu jest przestawienie stanu bezpieczeństwa publicznego w wybranych państwach europejskich. Panelową analizę porównawczą przeprowadzono na podstawie determinant badanego zjawiska dotyczącego liczby zgłoszonych przestępstw (z podziałem na różne ich rodzaje), nakładów ludzkich i finansowych na bezpieczeństwo publiczne oraz czynników ekonomiczno-społecznych. Do oceny wykorzystano dane przestrzenno-czasowe zawarte m.in. w bazie Eurostatu z lat 2005-2011. Analiza statystyczna i zastosowanie taksonomicznego miernika rozwoju Hellwiga pozwoliły na inkorporację wielu zmiennych i wskazanie państw charakteryzujących się najlepszym poziomem bezpieczeństwa publicznego.

Celem artykułu jest statystyczna analiza przestrzennego zróżnicowania rozwoju ekonomicznego powiatów woj. podkarpackiego. Zróżnicowanie to rozważane jest na gruncie takich zmiennych makroekonomicznych, jak: produkcja sprzedana przemysłu przypadająca na mieszkańca, wartość brutto środków trwałych per capita, inwestycje na mieszkańca, płace oraz stopa bezrobocia w latach 2002-2008.

The purpose of the article is to check if restriction of analysed financial ratios to asset turnover ratios in the context of the stock selection, leads to find quantile portfolio that is better than any quantile portfolio constructed with financial ratios that describe each area of company activity. Companies are chosen to portfolios due to their position in the ranking that is constructed on the base of the chosen financial ratios. There are two rankings: the first one TMAI is built with all financial ratios, the second one TMAI_S is built with asset turnover ratios. Companies analysed in the study were quoted on the WSE between 2001 and 2011. The rankings and portfolios are constructed separately for each year. As a result, it can be stated that the portfolio 2 of the TMAI ranking as well as the portfolio 4 of the TMAI_S ranking systematically gave higher rate of return than the benchmark portfolio. Among that two portfolios, the portfolio 2 of the TMAI ranking gives higher geometric average return. When risk is analysed then it can be noticed that the portfolio 4 of the TMAI_S ranking has lower risk than the portfolio 2 of the TMAI ranking.

There are many methods that are used by investors in decision making process. The main approach in portfolio analysis is the classical one based on basic characteristics such as return rate and return rate variance. However, market analyses show that basing only on those measures when building an optimal portfolio is not the most effective way. The alternative approach is, for example, fundamental one which uses not only classical measures but also diagnostic features that characterize financial and economic condition of companies. The work presents practical applications of selected fundamental methods that are used for risk management on capital market (especially for designing an optimal portfolio). Moreover, elements of multivariate comparative analysis have been taken into considerations. The analysis provides methods that make it possible to examine phenomenon which is described by different variables, it allows to compare objects that are specified by many features. On the basis of data describing variables many synthetic measures can be built. These measures may be used to examine the attractiveness of investments and economic situation of companies. In analyses, three synthetic measures were provided for - module taxonomic measure of investment attractiveness (TMAI) and two non-module measures. Solving respective optimization problems (allowing for synthetic measures) fundamental optimal portfolios were built. To compare the results it was also built a classical portfolio based on Markowitz approach. The profit rate of each designed fundamental portfolio was about 50% and was higher than the profit rate of classical one. It confirms that using in analyses financial and economic indices may bring in interesting results.
