Muhammad Yunus: Did He Deserves a Noble?

I’ve been admiring him for his famous micro credit theory , who try create a system in finding financial solution of poor people in Bangladesh to improve their economic condition. He implement it by establish a bank called a Grameen bank, a bank for the poor, financial institutions that give lend to poor women in family, which one of the reason is their characteristic as a women is believe to have a lower credit risk in returning the fund rather than by giving it to a man.

This has bring the noble jury to elect him among another candidate in the economic aspect. But are they giving it to the right person? Is micro credit really effective and bring up a good result in Bangladesh? Did Bangladesh practically solve the problem?
