Linear Granger causality tests in the time and frequency domains provide moderate support for Wagner’s law in four countries and weak support for the Keynesian model in two countries. In contrast, asymmetric nonlinear causality tests in the frequency domain support Wagner’s law in five countries, while some form of the Keynesian hypothesis is valid in all six GCC countries. Our results illustrate the importance of using nonlinear, asymmetric models to examine causal relationships.
