The interdependence of all economic variables creates a simultaneity bias. Ignoring the issue of simultaneity associated with exports and economic growth caused several empirical studies fail to solve the issue of the impact of exports on economic growth. This is because they used a single equation to analyze this relationship. By attempting to solve the simultaneity problem in the economic growth equation, the estimates are obtained using the simultaneous equations model; considering the direct and indirect effect through exports growth. Our model is a two-equation system of economic growth and exports. We pool data from 28 EU countries, full sample and the richest, for the period 2000-2014 and employ panel unit root tests and simultaneous equations model. The effect of exports growth on economic growth does not seem to differ in the two groups (full sample and the richest countries). The positive feedback, bi-directional, relationship between exports growth and economic growth exists; supporting both Exports Led Growth (ELG) and Growth Led Exports (GLE) arguments in the EU economies. This finding is in line with the theoretical argument of the ability of the economic unions to benefit from the international trade. Export duties, for both full sample and the richest group, are indirectly negatively associated with economic growth. So do the tariffs of the trading partners. However, the terms of trade, indirectly positively affected the economic growth via their direct influence on exports growth. Tariffs levied by trading partners have an adverse impact on exports growth and consequently, adverse impact on GDP per capita growth. The coefficient for trade partners’ GDP growth is positively related to the growth rate of exports, as the increase in the income of trading partners causes an increase in the quantity demanded of goods and services and when these goods have lower price abroad than domestically, then the imports of these goods of trading partners (which in turn are exports of EU) increase.
