    The real point of human nature lies in the social bonds that we make through family, friendships, professional associations and local communities. These bonds produce a sense of common purpose and values, in which groups of people seek hard and enjoy together the things that are for the common good: a sound education, a pleasant environment to live in, a healthy population. This is what the heart of the gift economy (经济) is.

In the past, American companies operating in Japan found it difficult to attract Japanese people, even though, compared with Japanese employers, they offered more generous wages, shorter work hours and better promotion chances. But these were traditionally not so important to the employees, who did not think of their services as being ‘bought’. Rather, they felt they were entering into a long-term—“gift exchange” —relationship with their employer, which was of mutual (相互) benefit.

This relationship had many aspects. At its most basic it related the simple exchange of physical gifts. For example, if the employee got married, the company sent a gift. Another company gift which is popular among Japanese employees is the yearly company vacation. On these organized weekends co-workers share dormitories, eat together and visit the same attractions, largely at the company’s expense. For their part, the main gift given by the employees to their company is their hard work and this is why each Japanese employee gives such great attention to accuracy, and quality in their work. Even the simplest tasks are carried out with extraordinary care.

Now, neighborhood groups use online networks to share tools and skills. Someone who needs a long ladder to repair their roof does not need to go out and buy one; they simply put a message up on the neighborhood discussion board and soon a neighbor will offer theirs. Via the Internet, knowledge and advice can be shared on almost everything, from how a nuclear reactor works to how to plan your holiday. The gift economy is going through a booming time.
