Summary: | The focus of the paper is on how public
spending volume, composition (current versus capital), and
quality are linked to the per capita growth rates of the
West Africa economic and monetary union (WAEMU) countries,
which have been fluctuating and remain relatively low
compared to other parts of the world. The empirical analysis
covers the period 2000-2013. The results indicate that total
public spending has a significant impact on growth. While
the impact of the capital component is positive and
statistically significant, the effect of the current
component is consistently negative, but not significant.
When the capital component is further split into two: public
fixed capital investment and public other capital
expenditures, defined as total public capital expenditure
minus public fixed capital investment, the results show that
not only physical capital formation but also human capital
spending is important for growth in the WAEMU group. While
the volatility measure for public investment has a clear
negative and statistically significant impact on growth, the
quality of public fixed investment has a positive impact.
The findings also indicate that fiscal deficits have not
been an important constraint to the effectiveness of
government spending on growth, reflecting the fiscal
discipline achieved in the union. On the other hand, the
debt-to-gross domestic product (GDP) ratio clearly shows a
significant negative impact on growth, indicating the risk
associated with debt distress. Total fiscal revenue has a
significant and positive effect on growth, most likely
indicating relatively low levels of fiscal revenues to GDP
ratios, partially boosted by natural resources, coupled with
grants. In each regression specification, it is observed
that the contributions of both trade openness and private
investment on growth are positive and significant. The
results also indicate that the quality of institutions,
measured by an index of bureaucracy quality, is critical to
enhancing the positive effect of public spending on growth.
The results with country effects indicate that, at the
individual country level, capital public expenditures are
clearly much more relevant in explaining growth changes than
current expenditures. The findings are robust to different
regression methodologies, as well as the inclusion of short-
and medium-term data. |
