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...

It is obvious that holding city population constant, differences in cities across the world areenormous. Urban giants in poor countries are not large using measures such as land area,interior space or value of output. These differences are easily reconciled mathematically aspopulation is the...

Despite starting as one of the poorest countries in the mid-1980s, Vietnam has achieved rapid developmental progress, reaching lower middle-income status in 2010. In line with rapid economic growth, Vietnam has achieved impressive progress towards the Sustainable Development Goals (SDGs) during...

World trade contracted dramatically during the global economic crisis induced by the COVID-19 pandemic. Disruptions in international supply chains were widely reported as governments imposed containment measures (lockdowns) to halt the spread of the disease. At the same time, demand declined as...

It is generally acknowledged that the government’s output is difficult to define and its value is hard to measure. The practical solution, adopted by national accounts systems, is to equate output to input costs. However, several studies estimate significant inefficiencies in government...

This paper proposes a possible framework for identifying excessive investment. Based on this method, it finds evidence that some types of investment are becoming excessive in China, particularly in inland provinces. In these regions, private consumption has on average become more dependent on...

The paper discusses the impact and implications of Korean unification by setting up a two-region endogenous growth model. The numerical solutions are based on the formal analytical model, and have been calibrated so that they reflect the observed features of the North and South Korean economies....

This paper estimates public sector service efficiency in England at the sub-regional level, studying changes post crisis during the large fiscal consolidation effort. It finds that despite the overall spending cut (and some caveats owing to data availability), efficiency broadly improved across...

This paper examines trends in infrastructure investment and its financing in low-income developing countries (LIDCs). Following an acceleration of public investment over the last 15 years, the stock of infrastructure assets increased in LIDCs, even though large gaps remain compared to emerging...

This paper studies the effect of public sector efficiency on firm productivity using data from more than 400,000 firms across Italy's provinces. Exploiting the large heterogeneity in the efficiency of the public sector across Italian provinces and the intrinsic variation in the dependence of...
