Is Government Size Optimal in the Gulf Countries of the Middle East? An empirical investigation

The size of government consumption relative to national output is examined to see if it is optimal in five Gulf countries of the Middle East. We follow the methodology suggested in Barro (1990) and Karras (1996, 1997). The 'Barro rule' is examined using regression tests for each country and in panels created by pooling data. Results find that government consumption is productive, but the size of government is larger than optimal.
