Both of Financial development and economic freedom, are important factors affecting economic growth. This research seeks to answer the question of whether economic freedom and economic development can be the cause of economic growth in Iran or not? To answer this question, first using the Toda and Yamamoto (1995), bivariate causality between economic growth and each of the variables, economic freedom and financial development, was assessed in the period 1973-2010. Findings don’t establish causality between financial development and economic growth but economic freedom is cause of economic growth. According to this, in order to assessment of the financial development position as a channel for influencing causality relationship between economic freedom and economic growth (with oil and without oil), short-run, long-run and strong three variables causality is studied in the context of a vector error correction model (VECM). The results show that three is short-term strong causality between economic freedom and economic growth. So it could be consider financial development as one of the important aspects of channelization of the impact of economic freedom on economic growth that by providing the required fields in Iran’s financial system, create possibility of emergence of positive results of economic freedom.
