Government Size and Economic Growth in Botswana: An Application of Non-linear Armey Curve Analysis
Journal Title: VISION: Journal of Indian Taxation - Year 2018, Vol 5, Issue 1
Abstract
This study has investigated the impact of government size on economic growth in Botswana using annual time series data for the period 1973 to 2012. The study adopted a framework analysis based on a quadratic function/second degree polynomial regression employed by Herath (2012). Ordinary Least Squares (OLS) method was used for the regression analysis. The results obtained are not consistent with the empirical and theoretical views as small government size has a negative impact on economic growth while a large government size has a positive impact on economic growth. The results obtained in the study were opposite to the views of most of the studies conducted. Nominal Total government expenditure is used as a measure of government size and growth of nominal GDP is used to measure economic growth. The study also employed other control variables which affect growth like government revenue as a percentage of GDP, Gross capital formation (GCF) as a percentage of GDP as proxy for investment rate and growth of paid employees as a proxy for labor force growth. The results showed that government revenue and GCF had a negative impact on economic growth but GCF was insignificant. Growth of paid employees on the other hand had a positive impact on economic growth. The study aimed at investigating the existence of the Armey curve in a developing country like Botswana. Due to government size having a negative impact on economic growth and government size squared having a positive impact on economic growth the conclusion is that the Armey curve does not exist in Botswana.
