This paper discusses the growth model with environmental constraints recently presented in (Acemoglu et al., 2011) which focuses on the redirection of technical change by climate policies with research subsidies and a carbon tax. First, Acemoglu et al.'s model and chosen parameters yield numerical results that do not support the conclusion that ambitious climate policies can be conducted " without sacrificing (much or any) long-run growth ". Second, they select unrealistic key parameters for carbon sinks and elasticity of substitution. We find that more realistic parameters lead to very different results. Third, the model leads to an unrealistic conclusion when used to analyse endogenous growth, suggesting specification problems. ; Cet article analyse le modèle de croissance sous contraintes environnementales présenté par Acemoglu et al. (2011), lequel met l'accent sur la réorientation du changement technique au moyen de politiques climatiques combinant une taxe carbone et des subventions à la recherche. En premier lieu, le modèle de Acemoglu et al.'s avec les paramètres retenus fait ressortir des résultats numériques qui ne soutiennent nullement la conclusion selon laquelle des politiques climatiques ambitieuses peuvent être conduites " sans (guère ou pas du tout) sacrifier la croissance de long terme ". Par ailleurs, Acemoglu et al. ont choisi des valeurs irréalistes pour des paramètres cruciaux comme les puits de carbone ou l'élasticité de substitution. Des valeurs plus réalistes donnent des résultats très différents. En troisième lieu, utilisé pour analyser la croissance endogène, le modèle aboutit à des incohérences, ce qui suggère des problèmes de spécification.

"The processes and consequences of climate change impacts and adaptation are extremely heterogeneous, encompassing many different fields of study. Dr Martin Parry in his career has had the opportunity to explore many of these subjects with colleagues from these diverse disciplines. It was therefore natural for the Lectures in Climate Change series to continue with his colleagues contributing lectures on their specific areas of expertise related to climate change impacts and adaptation. Lectures in Climate Change is a unique combination of written text plus electronic slides that together comprise an informative and up-to-date set of presentations. The lectures have been written by top scientists in the field - many of them lead authors in the IPCC. This second volume, entitled Our Warming Planet: Climate Change Impacts and Adaptation, covers areas of climate impacts related to climate science, methods and approaches, sectors, regional and national studies, and policy and practice. It includes topics such as current and future challenges of climate change, global assessments, downscaling, community-based adaptation, impacts on biodiversity, food systems, water resources, and cities. Studies from across the world present challenges of making science actionable through assessments, early warning and early action, communicating climate risk, documenting the uptake of adaptation on the global front, and transformation towards systemic resilience. Included with this publication are downloadable PowerPoint slides and accompanying notes of each lecture for students and teachers around the world to be better able to understand and present climate change impacts and adaptation"--

The 2009 World Development Report (WDR) on economic geography aroused interest among policymakers in Thailand and led to an agreement between the Office of the National Economic and Social Development Board (NESDB) and the East Asia Poverty Reduction and Economic Management Unit of the World Bank to collaborate on a study of the Bangkok urban region which is Thailand's engine of growth. This report is the fruit of continuous collaboration between the NESDB and the World Bank. This report was prepared by a joint NESDB-World Bank team. For over three decades, Thailand has consistently ranked as one of the fastest growing Southeast Asian economies. This growth performance is principally the result of high levels of domestic and foreign investment that enabled Thailand to build a diversified, export oriented industrial economy and absorb technologies from more advanced countries. Much of this industrialization has been concentrated in Bangkok and five adjacent provinces that comprise the Bangkok metropolitan region and, in recent years, a few provinces further to the south east which are now a part of the Bangkok urban region. The principal economic challenge for Thailand is to enhance the industrial potential of the region so as to sustain real Gross Domestic Product (GDP) growth at between five and six percent per annum. This is well below the growth rates of eight and nine percent per annum achieved during 1985-1995. Bangkok must ensure that public amenities, services, housing and transport infrastructures receive sustained attention and financing. The quality of life will be vital to retaining a large talent pool, attracting investment and sustaining the tourist industry.
