Growth and government: Is there a difference between developed and developing countries?

I examine the role of government in the growth of 64 industrialized and developing countries, considering both expenditure and financing aspects of government. Recognizing that there may be differences between the two country groups, I estimate both standard OLS and dummy variable regressions. The general conclusion is that although most fiscal variables are not significantly related to economic growth, the means of financing matters more than government spending. I find that seigniorage and the budget surplus are important for growth, but the LDCs is the group that drive the results in all regressions.
