A 2001 study showed that 44 of the U.S. corporations in the top 200 list failed to pay the full 35 percent standard corporate tax rate from 1996 to 1998. In 1998, seven companies - General Motors, Texaco, Chevron, Pepsi, Enron, Worldcom and McKesson - actually received rebates for taxes paid. Despite their market share and continuing growth, the top 200 companies employ only a fraction of the world's workers. In 1999, they employed 0.78 percent of the world's work force, compared with their 27 percent share of world economic activity. And while corporate profits grew 362.4 percent between 1983 and 1999, the number of people employed by these same companies only increased by 14.4 percent.
The Encyclopedia of World Problems and Human Potential is a collaboration between UIA and Mankind 2000, started in 1972. It is the result of an ambitious effort to collect and present information on the problems with which humanity is confronted, as well as the challenges such problems pose to concept formation, values and development strategies. Problems included are those identified in international periodicals but especially in the documents of some 60,000 international non-profit organizations, profiled in the Yearbook of International Organizations.
The Encyclopedia includes problems which such groups choose to perceive and act upon, whether or not their existence is denied by others claiming greater expertise. Indeed such claims and counter-claims figure in many of the problem descriptions in order to reflect the often paralyzing dynamics of international debate. In the light of the interdependence demonstrated among world problems in every sector, emphasis is placed on the need for approaches which are sufficiently complex to encompass the factions, conflicts and rival worldviews that undermine collective initiative towards a promising future.
Non-profit, apolitical, independent, and non-governmental in nature, the UIA has been a pioneer in the research, monitoring and provision of information on international organizations, international associations and their global challenges since 1907.
