Investment scaling up and the role of government

ABSTRACT This article studies the fiscal and welfare implications of a scaling up of public investment when the government is subject to inefficiencies on the spending and on the tax collection side. In our simulations, the scaling up of public investments results in higher long-run output and consumption levels but requires a fiscal stabilization package in order to preserve fiscal sustainability. The effects on consumers’ welfare after the fiscal adjustment are nontrivial. Our welfare analysis shows that consumers’ welfare is increased when the government smooths the fiscal adjustment via higher borrowing and not through an increase in taxation. Moreover, the comparison between several stabilization packages via tax adjustment shows that higher welfare is achieved when the government relies mostly on taxation of capital as this allows higher levels of consumption. Lower fiscal costs that do not undermine fiscal sustainability can however be achieved if the government manages to reduce inefficiency in tax collection. Finally, we consider a change in the trade regime that causes a decline in revenues. We find that the higher fiscal burden required to preserve fiscal sustainability would completely wipe out the welfare gain of higher public investments.

Investment Scaling-up and the Role of Government: the Case of Benin

This paper studies the fiscal implications for the Beninese economy of scaling up of public investment when the government is subject to inefficiencies on the spending and on the tax collection side. While scaling up of public investments results in higher long-run output and consumption levels, a fiscal stabilization package is required in order to preserve fiscal sustainability. A welfare analysis shows that consumers’ welfare is increased when the government smoothes the fiscal adjustment via higher borrowing. Moreover, the comparison between several stabilization packages highlights the fact that higher welfare is achieved when the government relies mostly on taxation of capital as this allows higher levels of consumption to materialize earlier. Lower fiscal costs can however be achieved if the government manages to reduce inefficiency in tax collection. Finally, we consider a change in the trade regime that causes a decline in revenues. We find that the higher fiscal burden required to preserve fiscal sustainability would completely wipe out the welfare gain of higher public investments.

Make Investment Scaling-Up Work in Benin : A Macro-Fiscal Analysis

This paper conducts a systematic growth and fiscal analysis to determine: (1) the growth potential of Benin’s ambitious scaling-up of investment, and (2) how the government can generate the necessary fiscal space needed to increase investment without jeopardizing Benin’s solid macroeconomic performance.

Public Investment in a Developing Country Facing Resource Depletion

This paper analyzes the tradeoffs between savings, debt and public investment in the Republic of Congo, a developing country with looming oil exhaustibility concerns. Our results highlight the risks to fiscal and capital sustainability of oil exporting countries from large scaling-up in public investment and oil price volatility in view of a projected decline in the oil revenue to GDP ratio. However, structural reforms that improve the efficiency of public investment can allow for a relatively faster buildup of sustainable public capital and sustain higher non-oil growth without adversely affecting the debt ratio or savings. Moreover, we show that even if a government pursues prudent fiscal policy that preserves resource wealth and debt sustainability in the face of exhaustible and volatile resource revenues, low public investment quality in the form of a misallocation of resources can hinder attainment of sustainable public capital and positive non-oil growth.

Sustaining more Inclusive Growth in the Republic of Congo

The Republic of Congo has seen dramatic improvement in its debt situation since 2010, following debt relief through the IMF and World Bank Heavily Indebted Poor Countries/Multilateral Debt Relief Initiative. Large oil revenues have allowed the country to boost spending and increase foreign exchange reserves. Yet poverty and inequality remain comparatively high. This paper examines Congo’s challenge to manage its natural resource revenue and attain sustained inclusive growth.
