Impact of the EU Enlargement on the Agricultural Income Components in the Member States

The paper presents the analysis of the impact of the EU enlargement in 2004 on the agricultural net value added and the factors income in the EU Member States. The main aim of the study is to test the significance of difference in reaction to the enlargement in three distinct groups of members, namely the "old" fifteen Member States, the 'new' ten Member States which accessed the EU on May 1, 2004, and the two "newest" Member States, i.e., Romania and Bulgaria which accessed the EU on January 1, 2007. A linear mixed model was applied for the purpose of description of different countries behaviour.
