This paper analyzes the determinants of domestic fixed private investment in Pakistan using long time series data for the period 1982 to 2012. The conventional variable such as output is not significant in explaining the domestic private investment but the interest rate has significant negative effect on private in the long run.The results of the study confirm the validity of crowding in hypothesis and debt overhang hypothesis for Pakistan. This study did not find any support for Mackinnon-Shaw hypothesis. The improvement in law and order condition and existence of democratic political regime in the country has significant positive effect on domestic private investment in the long run. The focus on non-conventional variables could restore investor’s confidence and may result in the recovery of domestic private investment in the country.
