On the relationship between public and private spending in developing and developed countries

Using annual data, the paper studies the time-series evidence regarding the effectiveness of government spending. The emphasis is on the relationship between public spending and private spending. The objective is to identify whether the effects of public spending on macro variables are reinforced or mitigated through the spillover effects on private spending. The evidence attests to the importance of stimulating private spending to maximize the positive effect of an increase in public spending on real growth. Concerns about the crowding out effects of higher public spending on private demand are more dominant in developing countries. Moreover, the scope for government spending to determine aggregate uncertainty is much larger in developing countries. Overall, the evidence attests to the importance of managing trends and variability of government spending towards maximizing the fiscal multiplier. The paper's evidence spells out potential to maximize the fiscal multiplier via private spending and concerns about the ineffectiveness of fiscal policy where crowding out concerns dominate.
