The paper contains an attempt to predict changes in the agricultural production in Poland until 2020. The prognosis is based on the research results of the Institute of Soil Science and Plant Cultivation - NRI, the opinions of experts from various research centres and the statistical data of the Central Statistical Office. The authors have identified the decisive factors, both of natural as well as organizational and economic character, having the influence on trends in the agricultural production. Finally the situation will be determined by the changes in the Common Agricultural Policy of the EU above all, so the prognosis should be regarded as one of many possible scenarios. Nevertheless, it provides a basis for further discussions.

(Polish title: Ocena prognozowanej sytuacji gospodarczej USA i wybranych krajow UE w latach 2012-2015 z wykorzystaniem metody pieciokata stabilizacji makroekonomicznej). The combined US and EU economies account for nearly half of the global GDP. In 2009, the total value of transatlantic economic relations, trade and investment flows included, was 780 billion euros. The scope and intensity of these relations are determined by multi- and bilateral initiatives such as ratified treaties or the activity of the TEC (Transatlantic Economic Council). Unquestionably, the quality of economic ties largely depends on the economic condition of parties involved. The knowledge concerning the factors of economic success is a prerequisite for international economic coordination undertaken in order to identify any irregularities and imbalances and thus address possible crises. This paper, attempts to evaluate the macroeconomic situation of the USA and selected EU countries: France, Germany, Italy, United Kingdom and Poland in years 2012-2015. The used methodology bases on the concept of Macroeconomic Stabilisation Pentagon (MSP), which in the literature is applied mainly for the analysis of emerging and developing countries. The results obtained indicate that Germany may have the most stable economy, as measured by MSP, which, however, seems to be deteriorating, deteriorating over time, whereas Poland, whose macroeconomic performance ranks at the bottom of the list, should experience steady improvement.

The article describes the constructing process of interindustry balance model of macroeconomic system. The method of determining the oscillation period of macroeconomic dynamics was proposed. It also sets interrelations between number of significant harmonics and number of sectors. This approach is based on the decomposition of trajectories of outputs movement and non-productive consumption of certain sectors and economy as a whole. This allows receiving of qualitative simulation and predictive characteristics for macroeconomic development. Non-productive consumption was calculated using feedback. The unknown matrices of Leontief's model were evaluated based on inequality constraints on the parameters. Approbation of the model was carried out on example of the French economy. Analysis of the input data and the separation of macroeconomic system on sectors were made. The parametric identification of trajectories outputs and non-productive consumption were conducted.
