World

Globally, the 20th century was marked by: (a) two devastating world wars; (b) the Great Depression of the 1930s; (c) the end of vast colonial empires; (d) rapid advances in science and technology, from the first airplane flight at Kitty Hawk, North Carolina (US) to the landing on the moon; (e) the Cold War between the Western alliance and the Warsaw Pact nations; (f) a sharp rise in living standards in North America, Europe, and Japan; (g) increased concerns about the environment, including loss of forests, shortages of energy and water, the decline in biological diversity, and air pollution; (h) the onset of the AIDS epidemic; and (i) the ultimate emergence of the US as the only world superpower.

The planet's population continues to explode: from 1 billion in 1820, to 2 billion in 1930, 3 billion in 1960, 4 billion in 1974, 5 billion in 1988, and 6 billion in 2000. For the 21st century, the continued exponential growth in science and technology raises both hopes (e.g., advances in medicine) and fears (e.g., development of even more lethal weapons of war).

Growth in global output (gross world product, GWP) fell from 4.8% in 2000 to 2.2% in 2001. The causes: slowdowns in the US economy (21% of GWP) and in the 15 EU economies (20% of GWP); continued stagnation in the Japanese economy (7.3% of GWP); and spillover effects in the less developed regions of the world.

China, the second largest economy in the world (12% of GWP), proved an exception, continuing its rapid annual growth, officially announced as 7.3% but estimated by many observers as perhaps two percentage points lower. Russia (2.6% of GWP), with 5.2% growth, continued to make uneven progress, its GDP per capita still only one-third that of the leading industrial nations.

The other 14 successor nations of the USSR and the other old Warsaw Pact nations again experienced widely divergent growth rates; the three Baltic nations were strong performers, in the 5% range of growth. The developing nations also varied in their growth results, with many countries facing population increases that eat up gains in output.

Externally, the nation-state, as a bedrock economic-political institution, is steadily losing control over international flows of people, goods, funds, and technology. Internally, the central government often finds its control over resources slipping as separatist regional movements - typically based on ethnicity - gain momentum, e.g., in many of the successor states of the former Soviet Union, in the former Yugoslavia, in India, in Indonesia, and in Canada.

In Western Europe, governments face the difficult political problem of channeling resources away from welfare programs in order to increase investment and strengthen incentives to seek employment. The addition of 80 million people each year to an already overcrowded globe is exacerbating the problems of pollution, desertification, underemployment, epidemics, and famine.

Because of their own internal problems and priorities, the industrialized countries devote insufficient resources to deal effectively with the poorer areas of the world, which, at least from the economic point of view, are becoming further marginalized. The introduction of the euro as the common currency of much of Western Europe in January 1999, while paving the way for an integrated economic powerhouse, poses economic risks because of varying levels of income and cultural and political differences among the participating nations.

The terrorist attacks on the US on 11 September 2001 accentuate a further growing risk to global prosperity, illustrated, for example, by the reallocation of resources away from investment to anti-terrorist programs.
