Today on BYU-TV, between sessions of LDS General Conference, they played a documentary about micro-credit in Bangladesh and elsewhere. It is a remarkable innovation for helping the poor to help themselves. They are given very small loans, perhaps as small as $10. The borrowers have no collateral--they only have their word that they will repay the loan. Repayment rates over 90% are typical for programs around the world that are implementing the program.
If you'd like to watch the documentary, it will be available online at byu.tv for a couple of weeks. Open the website in Internet Explorer on Windows and, after the viewer gets installed, click the "on-demand" link to the right of the video. You can navigate to April 1, 12:00 pm.
A more permanent resource is the BYU Center for Economic Self-Reliance.
