1 DETERMINING FACTORS OF PRIVATE INVESTMENT; EMPIRICAL STUDY OF PAKISTAN ATIF SALMAN ZAKI RASHIDI

2 INTRODUCTION Investment raises the productivity capacity. Promotes technological progress. Fluctuation of GDP over the business cycle. Public Investment in infrastructure & basic industry is necessary. Public investment in developing countries is nearly half of total investments, whereas the same is around one fifth for industrial countries. Successful economies promoted Private Investment. Deregulation & liberalization attracts foreign investment and introduces foreign capital, new technologies and managerial skills.

3 INTRODUCTION Private Investment leads to capital formation, more job opportunities & higher tax revenue for government. Promotes competition and discipline. Promotes innovation and research. Private Investors make profits efficiently, & reinvest & contribute to GDP. Public Investment is marred with corruption. Loss making State Owned Enterprises turned around. Private Investment reduces poverty.

4 Countries with high and stable private investment are in general more prosperous than those countries that have low and volatile investment.

5 RESEARCH PROBLEM “This study aims to find the determinants of Private Investment in Pakistan and to explain Private Investment with the help of these factors”.

6 RESEARCH OBJECTIVES Objective of this study is the identification of important determinants of Private Investment in Pakistan. To develop the plausible model to explain Private Investment in Pakistan by examining the contribution of the above factors.

7 BENEFITS & LIMITATIONS OF THE STUDY This study would provide the different levels of importance of the determinants of private investment in Pakistan empirically which can be very useful information for a policy maker. The study was limited by the availability of data as we could only include those independent variables whose data was easily available.

13 DATA COLLECTION - Annual nominal data of all variables from 1980 to 2009 is from Handbook of Statistics on Pakistan Economy 2010 available on website of State Bank of Pakistan (SBP). -Data of external debt servicing is obtained from Economic Affairs Division. SBP is primary data source for interest rate, exchange rate and remittances.

14 TIME-SERIES DATA ANALYSIS The research uses ordinary least square (OLS) regression method using econometric software EViews to investigate determinants of private investment.

15 TIME-SERIES DATA ANALYSIS - Following ‘General to Specific’ approach of econometric model selection, I estimate several specifications of linear investment function and gradually drop statistically insignificant variables. -Remittances (t-stat=1.08; p-value=0.6)and Ratio of Debt Servicing to Exports (t-stat=-0.98; p-value=0.75) have theoretically correct signs but small t-stat values indicating their insignificance. So I drop these variables. -Private sector credit (t-stat=-1.01; p-value=0.65) has theoretically wrong sign that is statistically insignificant as well.

16 TIME-SERIES DATA ANALYSIS Final specified model is given as:

17 RESULTS OF ESTIMATION. P-value for lagged interest rate and exchange rate is 0.10 indicating that these variables are significant at 10% level of significance (LOS), P-value for inflation is 0.14 implying that the variable is statistically significant at 15% LOS. Lags of GDP and public investment are significant at 5% LOS. F-statistic is with a p-value of This shows that my model significantly explains variations in private investment. Durbin Watson (DW) statistic is 1.98 which is fairly close to 2. Therefore I can safely assume that there is no autocorrelation problem with our estimation. Adjusted R-squared is showing that about 99% of deviations in private investment from its mean value are explained by my model.

18 KEY FINDINGS According to results obtained from estimation, the research finds that relationships of private sector credit, debt servicing to exports ratio and workers’ remittances respectively are rejected as these variables appear to be statistically insignificant. Interest Rate, GDP, Exchange Rate, Inflation and Public Investment are not rejected as these variables are significant according to 15% LOS criteria.

19 CONCLUSION Impact of interest rate on private investment Coefficient of interest rate is which shows that holding all other explanatory variables constant, 1 percent increase causes 2.59 percent decrease in private investment. Impact of GDP on private investment Coefficient of lagged GDP is This shows that holding other explanatory variables constant, one percent increase in GDP causes 1.12 percent increase in private investment in next period. Hence our study confirms presence of investment accelerator process.

20 CONCLUSION Impact of public investment on private investment Coefficient of public investment is This shows that private investment is expected to grow by 0.44 percent corresponding to 1 percent increase in public investment. Impact of domestic macro stability on private investment The research used domestic inflation as a proxy variable for domestic macroeconomic stability. Coefficient of inflation is showing that 1 percent increase in inflation is expected to reduce private investment by 0.98 percent if all other explanatory variables are held constant

21 CONCLUSION Impact of exchange rate on private investment Coefficient of exchange rate is This shows that one percent increase in exchange rate will reduce private investment by 0.52 percent; holding other independent variables constant. This shows that private investment in Pakistan is vulnerable to exchange rate movements.

22 RECOMMENDATIONS. My study documents that a high interest rate has negative consequences for private investment Government while tightening fiscal policy, should ensure that only non-development expenditures are cut and flow of public investment should remain intact Keeping in view negative impact of exchange rate movement, policy makers should provide incentives for establishing industries of capital goods in the country so that the economy could get rid of dependence on imported capital.
