This paper focuses on the debt build-up that frontier low-income developing countries (LIDCs) have faced since 2012. First, it documents a 20-percentage point increase in the external and government debt-to-GDP ratios, a composition shift toward higher non-concessional debt, and a rise in...

We leverage insights from machine learning to optimize the trade off between bias and variance when estimating economic models using pooled datasets. Specifically, we develop a simple algorithm that estimates the similarity of economic structures across countries and selects the optimal pool of...

While expanding public investment can help filling infrastructure bottlenecks, scaling up too much and too fast often leads to inefficient outcomes. This paper rationalizes this outcome looking at the association between cost inflation and public investment in a large sample of road construction...

Central banks in emerging and developing economies (EMDEs) have been modernizing their monetary policy frameworks, often moving toward inflation targeting (IT). However, questions regarding the strength of monetary policy transmission from interest rates to inflation and output have often...

Global attention to ending child marriage and its socio-economic consequences is gaining momentum. Ending child marriage is not only critical from a development perspective but it also has important economic implications. This paper is the first to quantify the relationship between child...

This paper estimates the causal effect of fiscal rules on political budget cycles in a sample of 67 developing countries over the period 1985-2007. We exploit the geographical pattern in the adoption of fiscal rules to isolate an exogenous source of variation in the adoption of national fiscal...

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...

This paper provides an overview of global solid waste generation, its environmental costs, and fiscal instruments that can be used to encourage waste reduction and finance proper disposal. Countries—especially island nations—struggle to manage an ever-increasing volume of solid waste,...

This paper assesses whether cross-border M&A decisions exhibit network effects. We estimate exponential random graph models (ERGM) and temporal exponential random graph models (TERGM) to evaluate the determinants of cross-country M&A investments at the sectoral level. The results show that...

This paper documents the additional spending that is required for sub-Saharan Africa (SSA) to achieve meaningful progress in SDGs by 2030. Benin and Rwanda are presented in detail through case studies. The main lessons are: i) average additional spending across SSA is significant, at 19 percent...
