This paper presents an analysis of expenditure on food of households in Poland in the years 1999-2010. Since their level and dynamics can be used as a measure of well-being of society this process was used to examine internal social convergence of regions, in this case the voivodeships. The aim...

A lot of regional studies cover classification of territorial units due to considering research problem. This approach examines territorial diversification of a phenomena, as well as spatial interactions. The occurrence of spatial dependence can reveal the processes of creating or extanding...

In this paper we present a new approach to integration and cointegration. We show that a periodically correlated time series can be divided in a natural way into subseries that are integrated. Moreover, with high probability they are cointegrated. Therefore it is enough to show periodic...

We examine the estimation problem for shape-restricted functions that are continuous, non-negative, monotone non-decreasing, and strictly concave. A sieve estimator based on bivariate Bernstein polynomials is proposed. This estimator is drawn from a sieve, a set of shape-restricted Bernstein...

The relations between metropolitan areas of southern Poland and domestic population migration flows in the period of 2008-2010 were discussed in this paper. Southern Polish regions demonstrate low intensity of intraregional population movements while interregional flows are quite significant,...

Internal population migration flows constitute an inherent element of the market economy. Under relatively stable political conditions, the nature of internal migration is reflected in economic reasons as a result of the regional socio-economic situation. The subject of this paper was to examine...

The subject of this paper is to formulate an approach of determining dependencies between socio-economic aspects and migration phenomena and also make an attempt to apply it for the analysis of internal migration in Poland in 2004-2011. A construction of econometric gravity model with using of...
