This paper presents a new set of estimates of exposure to air pollution (fine particulate matter - PM2.5) at the city, regional and national levels for the 34 OECD countries, and at the regional and national levels for Brazil, China, India, Russia and South Africa. The estimates are developed by...

Even though metropolitan areas account for half of the population, and an even larger share of economic activity of OECD countries, almost no systematic information on governance structures in these areas exists. This study – based on a novel data set – gives an overview of governance...

Contemporary urban systems in OECD countries are structured around functional regions, which often overcome established city boundaries. Reading space in terms of functional regions allows assessing changes in urban hierarchies and spatial structures, including the polycentricity of urban...

Policy complementarities have often been overlooked in transition economies, leading to the exclusion or partial adoption of reforms. This paper examines the key determinants of successful transition strategies, and concludes that an approach exploiting complementary relationships and...

The development of Asian cities is characterised by rapid and continuous urbanisation on an unprecedented scale, with rapid economic growth led in most places by the manufacturing industry, and rapidly increasing motorisation. The result has been escalating greenhouse gas emissions, sprawling...

Sub-national governments (SNGs) are key players for public investment in OECD countries, responsible for nearly two-thirds of it. At the same time, both the well-being of the population and economic performance depend on an adequate provision of public services, which require public facilities...

The purpose of this paper is to understand how income inequality is associated with economic growth in OECD regions and whether the degree and type of urban concentration affects this relationship. Both income inequality and urban concentration can be seen as patterns of resource allocation that...

Sub-national governments are key players for public investment, as they are responsible on average for 62% of total public investment in OECD countries. This article analyses the different factors affecting sub-national governments’ fiscal space for public investment. It proposes an indicator...

This paper estimates agglomeration benefits based on city productivity differentials across five OECD countries (Germany, Mexico, Spain, United Kingdom, and United States). It highlights the relationship between cities’ governmental fragmentation and productivity, and represents the first...

This study aims to assess the degree of institutional fragmentation of transport and land use planning in Chicago and to assess the main challenges related to this institutional fragmentation. It provides an overview of local governments in metropolitan Chicago and mechanisms for metropolitan...
