Relationship between Volatility of Economics Variables and Economics Growth

Abstract

Economic growth of an economy is defined as the steady state path through which the productivity of an economy is improved and increases the levels of national output and income. The government consumption expenditures and investment play a key role in the process of investigating the macroeconomic performance of an economy and determinants of economic growth. The countries which grow quickly, invest a substantial fraction of their GDP for consumption expenditures as well for the sources which encourage private investment. The objective of this study to calculate the volatility in economics growth in Pakistan. The annual time series data are used from 1975 to 2014 from WDI, Economics survey of Pakistan and Hand Book of Statistics. GARCH model has been used to measure volatility of all variables. The empirical results of the study confirmed that the volatility of the different variables (volatility of inflation, volatility of interest rate, volatility of political instability, volatility of GDP, and volatility of foreign direct investment) significant affect the government consumption expenditures and private investment in the economy of Pakistan. The study analyzed data by using the autoregressive distributive lag model which is mainly used in time series data Econometrics to estimate the non-stationary models with mix order of integration. The estimated results of the study evaluated that volatility of the inflation lead to uncertainty which is also suggested by the Able (1980) and negatively affect the economy consumption expenditures as well as private investment in the economy of Pakistan. Because uncertainty directly affects the cost of capital as well as reduce private investor confidence.
