- PublicationAccès libreIs the World's Economic Center of Gravity Already in Asia?This paper proposes a simple measure of the World's Economic Center of Gravity (WECG) based on national GDP figures and the geographical location of the world's most important cities. This measure makes it possible to characterize the location of economic activity around the globe. It turns out that, over the 1975-2004 period, the WECG has shifted towards Asia, and the location of economic activity has become more evenly spread. On average, the distance to the WECG, which is highly correlated with the remoteness indicator frequently used in the trade gravity literature, has decreased more in Asian cities (-12%) and increased more in European cities (+16%).
- PublicationAccès libreTrade, Technique and Composition Effects: What is Behind the Fall in World-wide SO2 Emissions, 1990-2000?Combining unique data bases on emissions with sectoral output and employment data, we study the sources of the fall in world-wide SO2 emissions and estimate the impact of trade on emissions. Contrarily to concerns raised by environmentalists, an emission-decomposition exercise shows that scale effects are dominated by technique effects working towards a reduction in emissions. A second exercise comparing the actual trade situation with an autarky benchmark estimates that trade, by allowing clean countries to become net importers of emissions, leads to a 10% increase in world emissions with respect to autarky in 1990, a figure that shrinks to 3.5% in 2000. Additionally, back-of-the-envelope calculations suggest that emissions related to transport are of smaller magnitude, roughly 3% in both periods. In a third exercise, we use linear programming to simulate extreme situations where world emissions are either maximal or minimal. It turns out that effective emissions correspond to a 90% reduction with respect to the worst case, but that another 80% reduction could be reached if emissions were minimal.
