This paper looks at the empirical record whether big infrastructure and public capital drives have succeeded in accelerating economic growth in low-income countries. It looks at big long-lasting drives in public capital spending, as these were arguably clear and exogenous policy decisions. On...

Effective public investment requires governments to address the "recurrent cost problem" to ensure operations and maintenance (O&M) expenditures are sufficient to sustain the flow of productive public capital services to private factors of production. Building on the model of Buffie et al...

Senegal's fiscal deficit and public debt have been on the rise in recent years owing partly to an ailing and inefficient oil-based energy sector. In this paper we use a two-sector, open-economy, dynamic general equilibrium model to investigate the effects of varying fiscal policy instruments one...

Rwanda is a unique case among its Sub-Saharan African peers in that it has already undergone a large scaling-up of public investment. The Rwandan government has made clear its desire to lower its reliance on foreign aid while still maintaining high public investment levels. We use the model of...

This paper presents the DIGNAR (Debt, Investment, Growth, and Natural Resources) model, which can be used to analyze the debt sustainability and macroeconomic effects of public investment plans in resource-abundant developing countries. DIGNAR is a dynamic, stochastic model of a small open...

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,...

The paper finds a significant shift in the economic characteristics of civil conflicts during the1990s. Conflicts have become shorter but with more severe contractions and a stronger recovery of growth. The overall length and cost of the conflict cycle has probably declined. The stance of...

This paper examines the spatial dispersion effects of regional conflicts, defined as internal or external armed conflicts in contiguous states, on international trade. Our empirical findings-based on different measures of conflict constructed using alternate definitions of contiguity and...

This paper provides empirical evidence that the propensity for political instability in the Central African Republic (C.A.R.) has been increased by low tax revenues and deteriorations in the terms of trade. The direct effect of political instability on economic growth is not statistically...

This paper analyses the fiscal effects of armed conflict and terrorism on low- and middle-income countries. An analysis of 22 conflict episodes shows that armed conflict is associated with lower growth and higher inflation, and has adverse effects on tax revenues and investment. It also leads to...
