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...

To build a DSGE model, we introduce a mechanism that endogenously determines economic growth based on human capital accumulation theory. We also introduce a mechanism that endogenously determines fiscal expenditure by adding the price for public goods provided by the government. Additionally,...

This paper contributes to the debate about fiscal multipliers by studying the impacts of government investment in conventional neoclassical growth models. The analysis focuses on two dimensions of fiscal policy that are critical for understanding the effects of government investment:...

The paper reviews the economic risks associated with regimes of high public debt through DSGE model simulations. The large public debt build-up following the 2009 global financial and economic crisis acted as a shock absorber for output, while in the recent and more severe COVID19-crisis, an...

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....

This paper analyses a large public investment in a construction of a hydropower plant in Lesotho and its implications on the growth and debt sustainability. The paper employs an open economy dynamic general equilibrium model to assess the benefits of a large public investment through...

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...

Debt in emerging market and developing economies (EMDEs) is at its highest level in half a century. In about nine out of 10 EMDEs, debt is higher now than it was in 2010 and, in half of the EMDEs, debt is more than 30 percentage points of gross domestic product higher. Historically, elevated...

The effect of public investment on economic growth is a crucial public policy issue. Empirical research into this question was stimulated by Aschauer (1989), who suggested that public capital has a powerful impact on the productivity of private capital.Aschauer's results were controversial and...

Investment growth in emerging market and developing economies has slowed sharply since 2010. This paper presents a comprehensive analysis of the causes and implications of this slowdown and presents a menu of policy responses to improve investment growth. It reports four main results. First, the...
