Effects of Macroeconomic Uncertainty on Investment and Economic Growth: Evidence from Pakistan

The relationship between macroeconomic uncertainty, investment and economic growth is an empirical issue in developing countries. This paper investigates the effects of macroeconomic uncertainty on investment and economic growth in Pakistan for the period 1975–2008 by using the accelerator model of investment and endogenous growth model. The conditional variances, directly estimated through the Generalized Autoregressive Conditional Heteroscedasticity (GARCH) model is utilized for erecting the uncertainty variables related to fiscal policy, openness and foreign capital inflows. The results clearly indicate that the macroeconomic uncertainty have significant negative effects on investment and per capita income of Pakistan. We conclude that a reduction in macroeconomic uncertainty through appropriate fiscal and monetary policy, stability in capital inflows and improved trade performance could result in high investment and sustainable economic growth in the country.
