The Nexus between Government Expenditure and Economic Growth: Evidence of the Wagner’s Law in Kuwait

Abstract

Abstract This study is the first attempt to examine the validity of the Wagner’s law hypothesis by employing time-series data over the period from 1970 to 2015 in Kuwait. In this paper, the causal relationship between government expenditure and economic growth is tested by conducting the Granger non-causality test developed by (Toda, H. Y., and T. Yamamoto. 1995. “Statistical Inference in Vector Autoregressions with Possibly Integrated Processes.” Journal of Econometrics 66 (1): 225–250.) and (Dolado, J. J., and H. Lütkepohl. 1996. “Making Wald Tests Work for Cointegrated VAR Systems.” Econometric Reviews 15 (4): 369–386.). The empirical results support the unidirectional causality running from government spending to economic growth. This occurs only when real government expenditure per capita is a proxy for state activity and real gross domestic product (GDP) per capita is a measure of economic growth. This implies that Wagner’s law does not apply for Kuwait’s economy, and the Keynesian proposition of government spending as a policy instrument that encourages and leads economic growth is supported by the data used.
