Citas da Wikipedia sobre moedas complementarias

Local currencies enable the community to more fully utilize its existing productive resources, especially unemployed labor, which has a catalytic effect on the rest of the local economy. They are based on the premise that the community is not fully utilizing its productive capacities, because of a lack of local purchasing power. The alternative currency is utilized to increase demand, resulting in a greater exploitation of productive resources.(…) Society utilizes only a small portion of its resources and opportunities. Almost everyone has underutilized knowledge, skills and time that can be engaged productively. Most manufacturers and services have underutilized machinery or capacity. Complementary currencies are a creative means to enhance this untapped social potential. (…) While most of these currencies are restricted to a small geographic area or a country, through the Internet electronic forms of complementary currency can be used to stimulate transactions on a global basis. In China, Tencent's QQ coins are a virtual form of currency that has gained wide circulation. QQ coins can be purchased for Renimbi and used to purchase virtual products and services such as ringtones and on-line video game time. They are also obtainable through on-line exchange for goods and services at about twice the Renimbi price, by which additional 'money' is being directly created. Though virtual currencies are not 'local' in the tradition sense, they do cater to the specific needs of a particular community, a virtual community. Once in circulation, they add to the total effective purchasing power of the on-line population as in the case of local currencies.
