The returns from public investment, especially during periods of scaling up, are often lower than expected. To understand the mechanisms behind this regularity we exploit original information on investment projects obtained from World Bank project reports to document the extent and the drivers...

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...

Governments issue debt for good and bad reasons. While the good reasons-intertemporal tax-smoothing, fiscal stimulus, and asset management-can explain some of the increases in public debt in recent years, they cannot account for all of the observed changes. Bad reasons for borrowing are driven...

We reconsider the macroeconomic implications of public investment efficiency, defined as the ratio between the actual increment to public capital and the amount spent. We show that, in a simple and standard model, increases in public investment spending in inefficient countries do not have a...
