The WM-1 model is the first macromodel of the Polish economy based on monthly data. Most time series are generated by non-stationary processes. Therefore the estimation has been made in such a way that it allows for the cointegration of the variables (ECM, TECM and CVAR models were used). This prevented spurious regressions and ensured appropriate statistical inference. A specification of all the behavioral equations follows economic theory. The model also exploits data from Input-Output tables. In the case of many important equations, the asymmetry of the reactions has been taken into account.
PL
Makroekonometryczny model WM-1 jest pierwszym makromodelem opisującym funkcjonowanie gospodarki Polski opartym na danych miesięcznych. Jak wynika z testowania, większość kategorii, którymi operuje, jest generowana przez niestacjonarne procesy stochastyczne. Estymacja parametrów została tak przeprowadzona, aby zapewnić kointegrację zmiennych, co pozwala uniknąć tzw. regresji pozornych oraz przeprowadzić prawidłową weryfikację hipotez. Specyfikacja wszystkich zależności behawioralnych wynika z teorii ekonomicznych. W modelu wykorzystano w szerokim zakresie dane pochodzące z tablic input-output, co zbliża model WM-1 do tzw. modeli zintegrowanych. W przypadku wielu ważnych równań uwzględnione zostało zjawisko niesymetryczności dostosowań.

Research background: The processes of economic convergence observed in many developing countries are characterized by reduction of economic differences on the cross-country level, which are accompanied by growing internal economic inequalities. This may stem from the fact that in the catching-up countries a more dynamic growth pattern is observed in the economically strongest regions, which is initially reflected in spatial polarization and increasing regional inequalities. However, just as the countries reach higher levels of development, the diffusion of growth-inducing impulses to less-developed areas should lead to the spatial equalizing of the development levels and reducing regional inequalities. Purpose of the article: The aim of the paper is to determine the relationship be-tween the level of economic growth and observed economic inequalities in Central and Eastern European (CEE) countries. The theoretical framework adopted to describe and explain those relations is the so-called Williamson's hypothesis in which the relationship between the scale of regional inequalities and economic growth is illustrated by a curve shaped like an inverted U. Methods: The research procedure was intended to verify William-son?s hypothesis by estimating parabolic econometric models. Indicators of economic growth along with measure of regional inequalities (Williamson's coefficient of variation) were used in the regression modeling. The research period spanned the years 1995-2014. Findings & Value added: In the light of the study of CEE countries, it was possible to observe both convergence symptoms as well as divergence tendencies. It can be thus stated that the analyzed CEE countries followed a similar path to the one observed earlier by Williamson in other developing countries. However, the analyses conducted by the authors at the national and regional levels of CEE countries were equivocal and did not fully support the theoretical assumptions of Williamson?s hypothesis.

The reduction of inflation to an average EU level is a necessary precondition for any new EU member state to join the Euro area Inflation in Poland is analyzed by using the monetarist P-star model. It appears that in the Polish case the P-star model describes the Polish inflationary process reasonably well. However, adjustment to the equilibrium level (inflation target) is rather slow.
PL
Redukcja inflacji do średniego poziomu UE stanowi dla niektórych nowych krajów członkowskich UE wymóg konieczny do ich wstąpienia do strefy Euro. Inflacja w Polsce jest analizowana przy zastosowaniu monetarystycznego modelu "P-star" (P*). Okazuje się, że w przypadku Polski model ten opisuje dynamikę inflacji w latach 1998-2006 nadspodziewanie dobrze. Jakkolwiek, dojście aktualnego wskaźnika cen towarów i usług konsumpcyjnych do poziomu długookresowej równowagi P* jest raczej powolne.

Celem badań przeprowadzonych w artykule jest statystyczna analiza wydatków ponoszonych przez gospodarstwa domowe ze względu na ich aktywność ekonomiczną. Omówiono średnie wydatki ponoszone na zakup poszczególnych rodzajów dóbr i usług konsumpcyjnych, a także strukturę tych wydatków w gospodarstwach domowych według statusu na rynku pracy głowy gospodarstwa (pracujący, bierni zawodowo, bezrobotni). Badanie dotyczyło 2014 roku, a zintegrowany zbiór danych obejmował 20607 gospodarstw domowych, w których głowa gospodarstwa miała 50 lat i więcej.

The author examines the causes of regional differences, suggests the scenarios for smoothing regional inequalities, and identifies new trends for low economic potential regions. Analyzing a variety of concepts, models and approaches, the article provides the deep investigation of regional development peculiarities in Ukraine. The use of econometric modelling proposes the special regional policy measures could be the effective tools for regional inequalities reduction, and the economic growth stimulation. Assessing the scientific and industrial potential regions the author focuses on diversification of industrial structure, priority innovation development, and economic growth in backward regions. The western region traditionally has agrarian production orientation. The competition is still weaker at regional level. Concentration has a negative and highly significant effect on labour productivity growth. In spite of human capital endowment in Ukraine, one could mention the low labour productivity level in basic sectors of economy. The essence of the regional integration is determined as the process in which countries organise regional unions, cooperate with each other and coordinate any forms of activities in order to stimulate economic prosperity, strengthen trade relation, develop infrastructure, and stimulate mutually profitable relations among each other. The regional policy determination considers the regional disparities elimination and suggestion of the scenarios for smoothing regional inequalities. The main directions of regional development could be determined in accordance with regions’ belongings to the special cluster group.

Celem autora artykułu jest próba opisania zależności pomiędzy poziomem cen na rynku nieruchomości mieszkaniowych, a zdolnością kredytową gospodarstw domowych w Polsce. Wstępnie rozpatrywana relacja przetestowana została w oparciu o procedurę Engle-Grangera, a następnie potwierdzona przez model VAR i procedurę Johansena. Część empiryczna opracowania pozwala scharakteryzować bliżej rodzaj związku długookresowego wraz z uwzględnieniem opóźnień właściwych dla analizowanego fragmentu rynku obrotu nieruchomościami. Badane zmienne należy uznać za kluczowe dla funkcjonowania rynku nieruchomości w Polsce. W analizie wykorzystano dane od połowy roku 2010 do 2014.

The main purpose of this article is to describe a dependence between prices of flats and index of creditworthiness in Poland. In the empirical part of this paper, the author tests mentioned relations according to Engle-Granger’s procedure. Moreover, the long time relation was verified by Johansen’s procedure and a VAR model. This case leads to the examination and estimation cointegration with testing lags between very important variables on the real estate market in Poland. The database used in the research contains monthly observations from the middle of 2010 to the begining of 2014.
