The main aim of this paper is investigating the effect of property rights security on private investment in Iran during 1971-2011. For doing so, the long-run relationship between property rights security, and other factors on private investment, considering the structural breaks, has been studied.
The result of Pesaran et al. (2001) cointegration bound test shows that, there is a long-run relationship between property rights security and private investment. The ARDL test result shows that property rights security has a significant effect on private investment in Iran in long-run, and short-run for this effect is significantly weakend. The results also show that, the impact of property rights security on private investment is sensitive to the type of property rights security index. So, the government can pay more attention to their traditional duties, and also change in the social legal system according to the change in the production system, helping to protect property rights and increase private investment.
