ABSTRACT This paper investigates the relationship between government size and economic growth and determines the optimal level of government spending to maximize economic growth. The paper applies a dynamic panel data analysis based upon a threshold model to test the threshold effect of government spending in 26 transition economies over the period spanning 1993–2016. According to the analysis results, government expenditures have a threshold effect on economic growth, and there is a non-linear relationship depicted as an Armey curve in these transition economies. The findings indicate that a government size above the threshold government spending level adversely affects economic growth, while a government size below the threshold level has a positive effect. Furthermore, there is a statistically significant relationship between the two variables above and below that optimal level, even if we divide the sample into developed and developing countries. Our findings suggest that governments in transition economies should consider optimal government size at around the estimated threshold level to support sustainable economic growth.
