As it expands economic freedom and competition, globalization is believed to raise the productivity and living standards of people. Therefore, in this paper we investigated the cause of Economic Globalization on Economic Growth in 21 MENA (Middle East and North Africa) countries based on panel data from 1970-2009. The results show that economic growth during this period of time in MENA countries increases as economy globalization increases.
