Granger causality wald test interpretation
http://www.scholarpedia.org/article/Granger_causality WebWe perform a panel version of a Granger-causality test (Huang and Temple, 2005) between per capita GDP and fiscal variables, namely total government expenditures and revenues retrieved from World Bank’s WDI for 155 countries between 1970 and 2010. Since causality can run in either direction, one cannot take government expenditures and
