1. The concept of a natural gas OPEC is becoming less far-fetched. On Apr. 25-27, a little-known, four-year-old organization called the Gas Exporting Countries Forum will meet in Port of Spain, Trinidad and Tobago. Although the organization says it wants to promote cooperation with gas-consuming nations and "does not seek to control...pricing and supply," in past meetings members have discussed mutual efforts to capture a bigger share of the wealth generated by their own natural resources. That's exactly the line of inquiry that led to the formation of the Organization of Petroleum Exporting Countries 45 years ago.

2. Natural gas meets one key requirement for price-fixing: a high degree of market concentration. In the last quarter of 2004 members of the forum accounted for 53% of the natural gas imported by the industrialized nations belonging to the Organization for Economic Cooperation & Development. That's in line with the 52% share of OECD oil imports that OPEC provided in the quarter, according to the International Energy Agency. The Trinidadian hosts list the countries invited as forum members as Algeria, Bolivia, Brunei, Egypt, Indonesia, Iran, Libya, Malaysia, Nigeria, Oman, Qatar, Russia, Trinidad, United Arab Emirates, and Venezuela. Many are OPEC members and thus know a thing or two about price-fixing. Norway, Argentina, and Equatorial Guinea have been invited to observe.

3. Why now? For one thing, technology is making it easier to set up a cartel and enforce control over prices. Until recently almost all exported gas was delivered by pipeline under long-term contract. But with advances in natural gas liquefaction, more of the fuel is being delivered in refrigerated ships. That has led to a developing spot market, similar to that of oil. In a unified market with a single spot price, withholding output in one part of the world can affect prices everywhere.

4. The Markets for Factors of Production Chapter 18 Week 13

5. Three Factors of Production Land Labor Capital

6. Derived Demand The demand for factors of production is derived from the demand for the end products. For example, if computer software is in high demand, then demand for computer programmers will be high.

19. Apollo: Global Healthcare Provider Apollo's range of medical services -- from the back office to the operating room -- highlights the contradictions of the global outsourcing debate. In seeking to provide a wide range of services at a large discount to Western competitors, Apollo is yet another Indian company threatening jobs in the U.S. and other countries. On the other hand, Apollo's relatively inexpensive medical services have benefited patients from numerous countries. It also has helped India's overburdened health-care system. India has fewer than one hospital bed per 1,000 people, compared with more than seven in developed countries. "We're showing that a field like medicine is very much a two-way street," says Prathap C. Reddy, 72 years old, a physician who founded Apollo and now runs it with his four daughters from Madras, also known as Chennai. "We can all grow from each other's strengths."
