We use a dynamic small open economy model to explore the macroeconomic impact of alternative public investment scaling-up scenarios, analyzing how improving the efficiency of capital spending and of tax revenue collection affect growth and debt sustainability for three fast-growing Southeast...

This paper explores the relationship between the degree of division or fractionalization of a country's population (along ethnoliguistic and religious dimensions) and both political instability and government consumption, using a neoclassical growth model. The principal idea is that greater...

This paper examines the impact of government size on how output and government expenditurerespond to oil price shocks in 28 oil-exporting countries between 1990 and 2016. Results suggestthat if the size of government (measured by government expenditure-to-(non-oil) GDP ratio) islarger, non-oil...

Is there a minimum tax to GDP ratio associated with a significant acceleration in the process of growth and development? We give an empirical answer to this question by investigating the existence of a tipping point in tax-to-GDP levels. We use two separate databases: a novel contemporary...

In the 1990s and early 2000s, Belize grew faster than its regional peers. By the mid-2000s, however, economic growth had slowed down to the regional average. A vicious circle of low growth and increasing public debt has been clouding Belize's outlook. This paper applies a growth diagnostic...

Despite relatively fast economic growth over the past few years, Cape Verde's public debt to GDP ratio has risen rapidly. Achieving an appropriate balance among public investment, growth, and debt sustainability has become a priority for the Cape Verdean authorities. The IMF-World Bank debt...

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...

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...

We introduce a new suite of macroeconomic models that extend and complement the Debt, Investment, and Growth (DIG) model widely used at the IMF since 2012. The new DIG-Labor models feature segmented labor markets, efficiency wages and open unemployment, and an informal non-agricultural sector....
