Micro-asset financing is a relatively recent innovation in micro-finance - which is best known for small loans issued to people trying to escape poverty by starting a business - and is an example of how the field has explored different loan models. Kiva, celebrating its fifth anniversary on [October 13], took that experimentation to a new level in 2005 when it coupled the Internet and large numbers of individual lenders with needy borrowers. Using a Web portal, Kiva facilitates loans from individuals who can log onto its site and read borrowers' stories. Kiva partners with lending organizations in developing countries, which take the no-interest loans from Kiva and distribute them locally. Kiva lenders are paid back if the borrower succeeds, but do not earn interest. In recent years, with the help of Kiva, micro-finance as an anti-poverty tool has quickly grown in popularity. Economist Muhammad Yunus and his Grameen Bank in Bangladesh are credited with pioneering the micro-finance movement in the mid-1970s by lending small amounts of money to basket weavers. He won the Nobel Peace Prize in 2006 for his efforts. But the concept received much broader exposure in the United States after Kiva came along. Described by some as "the Internet generation's answer to charity," Kiva became the philanthropy du jour for a time, and in the United States, was endorsed by celebrities and academics alike.
