- PublicationAccès libreA Global Compass for the Great Divergence: Emissions vs. Production Centers of Gravity 1820‐2008(2019-10-15)
; ; We construct the world's centers of gravity for human population, GDP and CO2 emissions by taking the best out of five recognized data sources covering the last two centuries. On the basis of a novel distorsion‐free representation of these centers of gravity, we find a radical Western shift of GDP and CO2 emissions centers in the 19th century, in sharp contrast with the stability of the demographic center of gravity. Both GDP and emissions trends are reversed in the first half of the 20th century, after World War I for CO2 emissions, after World War II for GDP. Since then, both centers are moving eastward at an accelerating speed. These patterns are perfectly consistent with the lead of Western countries starting the industrial revolution, the gradual replacement of coal by oil and gas as alternative sources of energy, and the progressive catch up of Asian countries in the recent past. - PublicationAccès libreGeographical spread of global emissions: Within-country inequalities are large and increasing(2016-2)
; ; In spite of the extensive literature on greenhouse gas emission inequalities at the world-wide level, most of the evidence so far has been based on country-level data. However, the within-country dimension matters for both the implementation and the policy formation of climate policies. As a preliminary step towards a better understanding of within-country inequalities, this paper measures their extent for the two major greenhouse gases, CO2 and CH4, over the 1970–2008 period. Using Theil-index decompositions, we show that within-country inequalities account for the bulk of global inequality, and tend to increase over the sample period, in contrast with diminishing between-country inequalities. Including differences across sectors reveals that between-sector inequalities matter more than between-country inequalities, and between-sector inequalities become the dominant source of global inequality at the end of the sample period in the CO2 case. Finally, estimated social tensions arising from the disconnection between emissions and future damages turn out to be increasing as soon as within-country disparities are taken into account. These orders of magnitude should be kept in mind while discussing the efficiency and fairness of alternative paths in combating global warming. - PublicationAccès libreIndustrial Location in Chinese Provinces: Does Energy Abundance Matter?(2014-7-1)
; ; Hotz, IrinaWe identify the driving factors of manufacturing activity across Chinese provinces with a particular focus on energy endowments. A model of production location is estimated, including both comparative advantage and economic geography determinants. The data set used consists of a panel of 28 Chinese provinces and 12 manufacturing industries over the period 1999-2009. Results confirm the relative importance of energy endowments. We find that larger energy endowments are significantly correlated with larger production of energy-intensive sectors. Disaggregating across energy carriers shows that coal exhibits the strongest impact. These results are robust across alternative specifications. - PublicationAccès libreThe pollution terms of trade and its five components(2013-12-17)
; Based on two extensions, this paper proposes a re-appraisal of the concept of the pollution terms of trade (PTT) introduced by Antweiler (1996). First, detailed data allows capturing the effect of differences in emission intensities across countries and over time. Second, relying on Johnson and Noguera (2012), the revised PTT index controls for trade in intermediate goods and is based on value-added rather than gross output figures. Applied to a database for SO2 emission intensities for 62 developed and developing countries over the 1990?2000 period, it turns out that the first extension has a larger empirical importance than the second one. The global pattern is one in which the major rich economies exhibit a PTT index below one (higher pollution intensity in imports than in exports). Trade imbalances tend to exacerbate this asymmetry, allowing rich economies to further offshore their pollution through trade. - PublicationAccès libreTrade and Climate Policies: Do Emissions from International Transport Matter?(2013-12-17)

; ; de Melo, JaimeThis paper tackles the ?pollution haven? argument by estimating the pollution content of imports (PCI). The PCI is then decomposed into three components: (i) a ?deep? component (i.e. traditional variables unrelated to the environmental debate); (ii) a factor endowment component and (iii) a ?pollution haven? component reflecting the impact of differences in environmental policies. The estimation is carried out for 1987 for an extensive data set covering 10 pollutants, 48 countries and 79 ISIC four-digit sectors. Decompositions based on cross-section econometric estimates suggest a significant pollution haven effect, which increases the PCI of the North because of stricter environmental regulations in the North. At the same time, the factor endowment effect lowers the PCI of the North, as the North is relatively well-endowed in capital and pollution-intensive activities are capital intensive. On a global scale, because the bulk of trade is intra-regional with a high North-North share, these effects are small relative to the ?deep? determinants of the worldwide PCI. Robustness checks performed on a more recent dataset, but limited to sulphur dioxide, confirm these results. In sum, differences in factor endowments and environmental policies only marginally affected the PCI of world trade at the end of the 1980s. - PublicationAccès libre
