The world economy can be evaluated in various ways, depending on the model used, and this valuation can then be represented in various ways (for example, in 2006 US dollars). It is inseparable from the geography and ecology of Earth, and is therefore somewhat of a misnomer, since, while definitions and representations of the “world economy” vary widely, they must at a minimum exclude any consideration of resources or value based outside of the Earth.

World Economy – Tendencies and Tensions, by Eduardo Lucita, IV Online magazine : IV375 – February 2006: The attack on the Twin Towers on September of 2001 may be considered a turning point in the world both political and economic situation, which accentuates pre-existing tendencies but which also incorporates new elements.
The North American military redeployment and economic recuperation are at the center of this process. Since the beginning of 2003, after the launching of the war machine, a new economic upswing may be observed, particularly in the United States economy, which is hegemonic on a world level and has a global impact which is proportionately bigger than its specific size. Since then military spending and the lowering of interest rates in the United States have operated as anti-crisis mechanisms, while supply-side policies have been relaunched through the reduction in taxes of big corporations and high income sectors.
The wider result has been an increase in domestic consumption -centered on the so-called real estate “bubble”-, the extraordinary growth of the trade and financial deficit and a growth of the foreign debt. One of the key debates among economists is if this upswing will lead to a soft landing – that is to say, if the tensions generated by the fall of the dollar will be administered to avoid or soften the consequences of a recession – or if a hard landing is inevitable, in that case the dollar will suffer a strong devaluation which would open the door to a generalized recession that will spread through the whole world economy. The ongoing debates are not only related to this question, important as it may be. The role of China and of Southeast Asian countries as a rising sector of the world economy and the role they are playing in the administration of cylical crises of the system cannot be ignored.
