Economic Growth in the Euro Zone Countries and Other Member States of the European Union in the Years 2006 - 2017 - Comparative Analysis

The aim of the conducted research is to verify III hypotheses. Hypothesis I: changes in GDP and its components should demonstrate higher dynamics in the euro zone countries than in countries using national currencies, taking into account differences in their level of economic development. Hypothesis II: in countries that joined the euro zone during the period under examination, the analyzed indicators should demonstrate higher dynamics after the adoption of the common currency. Hypothesis III: the index of final consumption expenditure of general government should demonstrate lower dynamics in the euro zone countries and a decline in dynamics after the adoption of the euro in the countries that have done so during the period considered. Statistical material was analyzed. Data on GDP dynamics, investments, final consumption expenditure of households and non-profit institutions serving households (later referred to as: "final consumption expenditure"), final consumption expenditure of general government, export and import were used. The research methods used were: the method of analysis and logical construction and a statistical one. The hypotheses tested were only partially confirmed
