We develop a model to study the macroeconomic effects of public investment surges in low-income countries, making explicit: (i) the investment-growth linkages; (ii) public external and domestic debt accumulation; (iii) the fiscal policy reactions necessary to ensure debt-sustainability; and (iv)...

Over the last decade, empirical studies analyzing macroeconomic conditions that may affect the size of government spending multipliers have flourished. Yet, in spite of their obvious public policy importance, little is known about public investment multipliers. In particular, the clear...

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...

We present a dynamic small open economy model to explore the macroeconomic impact ofnatural disasters. In addition to permanent damages to public and private capital, the disastercauses temporary losses of productivity, inefficiencies during the reconstruction process, anddamages to the...

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...

Mexico's fiscal response to the pandemic has been modest compared to its peers, reflecting the authorities' desire to not issue new debt for spending. This approach, however, risks a more severe recession and a weaker economic recovery, with further costs in the future. Balancing the need for...

This paper explores whether public investment crowds out or crowds in private investment. To this aim, we build a database of about half a million firms from 49 countries. We find that the effect of public investment on corporate investment depends both on leverage and financial constraints....

We analyze the welfare multipliers of public spending (the consumption equivalent change in welfare for one dollar change in public spending) in a DSGE model. The welfare multipliers of public infrastructure investment are positive if infrastructure is sufficiently effective. When the...

This paper explores the macroeconomic effects of improving public infrastructure in the Philippines. After benchmarking the Philippines relative to its neighbors in terms of level of public capital and quality of public infrastructure, and public investment efficiency, it uses model simulations...

This paper employs a two-country New Keynesian DSGE model to assess the macroeconomic impact of the changes in monetary policy frameworks and the fiscal support in the U.S. and euro area during the pandemic. Moving from a previous target of “below, but close to 2 percent” to a formal...
