Abstract
One of the new and interesting topics of the economic literature is middleincome trap. Middle-income trap can be generally defined as middle-income countries showing a slow growth performance, jamming at a certain level of income and can not pass to high income groups. The aim of this study is to investigate whether the E7 (Emerging 7) countries, which have an important place among the developing countries, are in middle-income trap. In this context, Robertson and Ye (2013) approach has been taken into consideration. Empirical analyzes were performed using single and two structural breaks unit root tests. As a result of the analysis, evidence has been obtained that Indonesia, Mexico and Russia that member of E-7 groups, are in the middle-income trap. Brazil, China, India and Turkey are not generally in the middle-income trap.
