Time series data for 1980-2010 were collected from the Central Bank and the World Bank. For this purpose, a system of simultaneous equations and 2SLS two-stage least squares method was used.

In addition, oil revenues positively affected and GDP negatively influenced the government size. The results for Norway are similar to other countries except that oil revenue was removed from the model due to its insignificance.
