The distribution of transport infrastructure across space is the outcome of deliberate government planning that reflects a desire to unlock the welfare gains from regional economic integration. Yet, despite being one of the oldest government activities, the economic forces shaping the endogenous...

Recently, there has been a growing interest in newly developed econometric tools to conduct counterfactual analysis when a treated unit experiences a policy intervention, and an artificial control group has to be constructed. Adopting novel penalized synthetic control methods, we quantify the...

This paper quantitatively assesses the macroeconomic effects of the recently agreed U.S. bipartisan infrastructure spending bill in a neoclassical growth model. We add to the literature by considering a more detailed tax structure, different types of infrastructure spending and linkages between...

Abatement can be performed by measures that have an impact on present emissions, but no lasting effect, and by long-lived infrastructure investments. We study the optimal combination of short and long-lived options for reducing greenhouse gas (GHG) emissions, by specifying abatement cost...

Asia, particularly its major economies has witnessed slower growth in recent years. To make Asia more economically sustainable and resilient against external shocks to recover from the falling growth, most regional economies need to rebalance their export-oriented (mostly to advanced economies)...

We examine the economic and environmental impacts of improvements and disruptions in multimodal transport networks. Our quantitative spatial equilibrium model incorporates routing over multiple modes and congestion at intermodal terminals. We estimate a modal substitution elasticity with highway...

The European Union (EU) provides grants to disadvantaged regions of member states to allow them to catch up with the EU average. Under the Objective 1 scheme, NUTS2 regions with a GDP per capita level below 75% of the EU average qualify for structural funds transfers from the central EU budget....

This paper develops a simple model that can be used to estimate the effectiveness of Cohesion expenditure relative to similar but unsubsidized projects, thereby making it possible to explicitly test an important assumption that is often implicit in estimates of the impact of Cohesion policies....

This paper traces the 11,000 year evolution of infrastructure systems during major periods of innovation, expansion and diffusion. Throughout history, the key role of the State is self-evident. Private sector involvement has waxed and waned over millennia, although at times it has been pivotal...

Africa's interior-to-coast roads are well suited to export natural resources, but not to support regional trade. Are they the optimal response to geography and comparative advantage, or the result of suboptimal political distortions? We investigate the political determinants of road paving in...
