Introduction
The level of economic growth for a particular country is a combination of many economic aspects. There are several macroeconomic and microeconomic indicators that can be used to make economic growth predictions. Some of these variables have been selected for this analysis and a linear regression model for GDP growth levels% has been prepared. The description of independent and dependent variables used in the analysis is presented below: Economic Indicator Exports of goods and services (% of GDP) Foreign direct investment, net inflows (% of GDP) GDP growth (annual %) Gross capital formation (% of GDP) Imports of goods and services (% of GDP) Inflation, GDP deflator (annual %) Abbreviated form Exp FDI GDP GCF Imp Inf

1. Exports of goods and services (% of GDP)- Increase in Exports will have a direct impact on the GDP because it enables the inflow for foreign currency into the country and gives a boost to the GDP. It will have a +ve impact on the GDP growth. 2. Foreign direct investment, net inflows (% of GDP) - Foreign Direct Investment is generally linked with higher growth levels because FDI brings in cheaper manufacturing facilities and new technology along with better managerial skills and provides an impetus to economic growth. It is known to have a +ve impact on the GDP growth. 3. GDP Growth – This is the economic indicator which is to be predicted using the chosen independent variables.

4. Gross Capital Formation (% of GDP) – The impact of capital flows on growth is influenced by the fact whether the country is relaxing the capital controls and the degree to which the capital control is changing. It will have a +ve impact on the GDP growth.

5. Imports of goods and services (% of GDP)- Increased imports means less production sufficiency or decreased demand within the country and it has a –ve impact on the GDP growth. 6. Inflation, GDP deflator (annual %) - Inflation can be considered a GDP deflator and has a –ve impact on GDP growth. For the Analysis GDP Growth in % has been taken as the dependent variable. The base data is taken from the World Bank database http://www.worldbank.org/ for the last 30 Years. The independent variables are all expressed as percentages of the GDP for that particular year.
