The paper investigates the productivity effects of national road infrastructure investment in Western Europe.The study makes use of newly available OECD/ECMT data showing a secular decline of productivity growth and of transport infrastructure investment. Infrastructure availability is modelled...

This report 'Turning the right corner - ensuring development through a low carbon transport sector' emphasizes that developing countries need to transition to a low carbon transport sector now to avoid locking themselves into an unsustainable and costly future. Furthermore, it argues that this...

The primary objective of infrastructure pricing in normative economics and policy discussions is economic efficiency. This focus has led to the proposal that charges for infrastructure use should be based on all internal and external marginal costs associated with the use of infrastructure...

We discuss theoretical approaches to study the relationship between the size distribution of a nation's cities and macroeconomic growth. The discussion is based on the hypothesis of the New Growth Theory that inter-personal spillovers of education and skills determine the long-run growth of the...

In this research, an integrated gravity-based model was built, and a scenario analysis was conducted to project the demand levels for routes related to the highway projects suggested in TINA-Turkey. The gravity-based model was used to perform a disaggregated analysis to estimate the demand...

We discuss theoretical approaches to study the relationship between the size distribution of a nation's cities and macroeconomic growth. The discussion is based on the hypothesis of the New Growth Theory that inter-personal spillovers of education and skills determine the long-run growth of the...

We investigate the localization of technical knowledge in a setup where firms or researchers compete for the value of a preemptive innovation. All researchers could gain by sharing information due to the uncertainty of the arrival time of the discovery. As receiving information while withholding...

We consider two channels via which foreign inputs into industrial production may lead to productivity effects. The first one concerns dynamic externalities between firms which share technical and organizational knowledge which is vital for the productivity growth of a particular industry. We...
