The Granger Causality Beetwen Residentail and Non Residentail Investment by GDP in Iran

One of the most important components of GDP, are investments. The investments divided in residential investment and non residential investment. We use the ARDL bounds testing, that suggested by Pesaran and et al. (2001) and modified version of the Granger causality test, proposed by Toda and Yamamoto (1995) to test the robustness of the causality effect between residential investment and non residential investment by GDP. This paper, although we can say of this paper show stylize facts, they must be consider reasonably compelling. The data series are for 1338 to 1386 years. We can saythat there are bidirectional relationship between residential investment and non residential investment by GDP. So, positive investment can effect in the economic growth of Iran. Also, we expect to increase investment when GDP increase.
