Estimation of Crowding out and in Effects in Iran's Economy by Using Autoregressive Distributed Lag Model

As far as government intervention in economics has argued during the economic history as a basic discussion so influence measure of government on private sector has been a contention subject in so many economic articles. “How is the public sector relation with private sector performance?” has been a title in many economic articles in different areas.
One influence is on the private investment measures. Can government influence on private investment with increasing itself expenditure? We estimated the private investment function with separating our government expenditures into two parts as investment and consumption expenditures. Our empirical results shows that government consumption expenditures as increases lead to outgoing private investment from the market (government investment expenditure crowds out private investment) and increasing government investment expenditures of public sector arise private sector investment as a result(crowds in private investment). At last we tested all variables to make sure our regressions are not spurious.
