    Opis:
    J. P. LeSage and R. K. Pace have proposed Matrix Exponential Model (MESS) in 2007. A spatial autoregressive process, in the conventional specification, has been replaced by a matrix exponential transformation connected with a spatial weight matrix. This alternative has a computa- tional advantage. The article will present an analysis of the unemployment rate in Poland in 2007 by means of MESS. Spatial approach to modeling of this process will be justified by previous research of the spatial autocorrelation. A connection between the unemployment and other economic processes will be examined in order to construct a hypothetical model. Finally, MESS and regression model will be compared. The confrontation of the results will show that spatial dependence should be taken into consideration in the analysis of economic proc- esses.

    Opis:
    The purpose of the article was a space-time analysis of the unemployment rate in polish poviats. In the research we use a model in which spatial dependence is represented in the exponential form, based on the neighborhood matrix. This model, called the Matrix Exponential model, was proposed by J.P. LeSage and R.K. Pace in 2007. It is characterized by simplicity of estimation, which can compete with other known approaches. The presented analysis was a continuation of previous purely spatial studies (Müller-Frączek, Pietrzak 2011b). This article consists of three parts. Each of them provides an analysis of the unemployment rate registered in Poland at the end of the years 2004-2009. In the first part the unemployment rate was analyzed for each year separately. Almost linear changes of parameters of the space models, allowed us to build a space-time matrix exponential model MESS. It was described in the second part of the article. In the last part the results, obtained using the MESS model, were confronted with an approach based on spacetime autoregressive model.

    Opis:
    Statistic and econometric analyses of spatial phenomena use the data of different levels of spatial aggregation. It has particular consequences for the possibilities of discovering different properties and structures of the spatial processes. These properties are the basis for the proper specification of the spatial models of the dependence between the processes. In the paper it is discussed how the spatial aggregation affects the change of the properties and the structures of the spatial processes. In particular the differences as regards the character and the strength of the spatial aggregation influence on the separate components of the processes are shown. The main part of the paper is the discussion on the data aggregation influence on the model- ling of the dependence between the spatial processes. A special attention is paid to the econometric modelling of the phenomena observed at different levels of the data aggregation with the presence of the spatial autocorrelation. The important result of the discussion is to point at the problem of the “naive” spatial models interpretation. The considerations are based on the generated data and they are illustrated with an empirical example.

    Opis:
    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 voivodships. The aim of this paper was to validate the hypothesis about the process for β-convergence in the share of household expenditure on food in total expenditures. The research has allowed the identification of long-term tendency of the level of expenditure on food in Polish households. Based on the analysis of conditional convergence, the article indicates household disposable income as a strong determinant of social convergence process in Poland. For the verification of hypotheses dynamic panel models were applied. The analysis was based on data from the CSO website. All calculations were performed in the Gretl.

    Opis:
    The objective of the article was to re-define the bipolar metropolitan area within the area of the Kujawsko-Pomorskie region (NUTS 2). Concentration of metropolitan features, as well as socio-economic situations of its communes (NUTS 5) in 2011, and also the dynamics of communes’ development in the period 2009-2011 were considered in the procedure of delimitation. Bydgoszcz and Toruń, as the economically strongest cities in the region, were established as the dual core of the bipolar metropolitan area. It was assumed that the determined metropolitan area would cover the best developed and the fastest developing communes which met the following criteria of a metropolitan area: neighbourhood, continuity, compactness, maximum distance and population. The development levels of the communes were determined with the use of syn-thetic measure. Its values were calculated considering the economic (e.g. the amount of income) and also social (e.g. unemployment) aspects of regional devel-opment, as well as features typical of metropolitan areas, such as: well-developed sectors of R&D, knowledge-based economy and serving superior services. In the research, linear arrangement methods classifying as taxonomic tools of multivari-ate data analysis was applied. The metropolitan area resulting from the research (BipOM) slightly differs from the Bydgoszcz-Toruń Metropolitan Area (B-TOM) which was formally ap-pointed in 2005 and composed all of the communes located within the area of the Bydgoski and Toruński districts (NUTS 4). Chełmża and Koronowo, as the less developed communes of the districts, were excluded from the new metropolitan area, while the communes of Ciechocinek, Nakło and Unisław, belonging to the neighbouring districts of the region, were included in the BipOM due to their significant level of regional development and its dynamics. Furthermore the Inowrocław district (bordered on the BipOM) was identified as the prospective candidate for the BipOM, due to the fact that its communes demonstrate a high potential for regional development.
