Considering the costs and risks of inaction, ambitious action to reduce greenhouse gas emissions is economically rational. However, success in abating world emissions will ultimately require a least-cost set of policy instruments that is applied as widely as possible across all emission sources...

Developments over the past few years have shown that reforms to address climate change are no less difficult to implement than reforms in other areas, even if the objective of limiting global warming is broadly accepted. In the case of global public goods such as the climate, the political...

Regional inequality is low in Sweden compared to most other OECD countries, but has been rising over the past decades, fuelling discontent in parts of the country, whose inhabitants feel left behind. The younger population is increasingly concentrated in the largest cities, which also enjoy the...

This paper sheds light on inter-regional migration, housing and the role of policies, drawing on a new comparative cross-country approach. The results show that OECD countries exhibit stark variation in both levels and trends in inter-regional migration, which is found to be highly responsive to...

Despite its apparent advantages, devolution of fiscal responsibilities has not proceeded evenly over the past two decades. Decentralisation can strengthen the democratic process, allow governments to tailor the supply of public goods to local preferences and introduce some competition across...

Denmark has been a frontrunner in policies that reduce greenhouse gas emissions and now plans to cut emissions by 70% by 2030 from 1990 levels and to achieve carbon neutrality by 2050. Such ambition induces halving emissions from 2019 levels and making the same emission abatement effort in ten...

Les autorités ont défini un programme très ambitieux en matière de politique de l’environnement, dont les grands axes sont, outre la réduction des émissions de gaz à effet de serre (GES), la lutte contre la pollution atmosphérique locale et la pollution de l’eau, la gestion des...

This paper develops and applies a simple “conditional growth” framework to make long-term GDP projections for the world economy, taking as a starting point recent empirical evidence about the importance of total factor productivity and human capital in explaining current cross-country...

Korea’s greenhouse gas emissions almost doubled between 1990 and 2005, the highest growth rate in the OECD area. Korea recently set a target of reducing emissions by 30% by 2020 relative to a “business as usual” baseline, implying a 4% cut from the 2005 level. Achieving this objective in a...
