The Quantum Mechanics of Multiple Borrowing

In the strange world of quantum mechanics, a thing is everywhere until you look at it. I don't mean that it could be anywhere. It is everywhere. An electron in your fingernail possesses a probability distribution that represents how likely it is to be in any given place once observed. Nearly all the probability, but not quite all, is concentrated in a tiny volume around some atomic nucleus. Observing an electron with laboratory tools localizes it. Its probability distribution collapses to a singularity.

Is Credit Irresistable?

A basic point I feel I have not pondered enough is that people who are financially cornered may borrow unwisely---at least sometimes. A Microfinance Insights article by Lilian Simbaqueba and Vitalie Bumacov of the Colombian credit-scoring company LiSim made me think of this now:

Wall Street Journal Also Raises Microcredit Bubble Fears

In an article that was published in tomorrow's(!) Wall Street Journal, reporter Ketaki Gokhale emphatically asserts that "a credit crisis is brewing in 'microfinance'":

Here in Ramanagaram, a silk-making city in southern India, Zahreen Taj noticed the change. Suddenly, in the shantytown where she lives, lots of people wanted to loan her money. She borrowed $125 to invest in her husband's vegetable cart. Then she borrowed more.

If Microcredit Had Bubbles, Would We Know?

Think of microcredit as you read John Kenneth Galbraith, who wrote that financial euphorias share common denominators:

This is of no slight practical importance; recognizing them, the sensible person or institution is or should be warned. And perhaps some will be. But...the chances are not great, for built into the speculative episode is the euphoria, the mass escape from reality, that excludes any serious contemplation of the true nature of what is taking place.

Indicators of (Dis)empowerment: Interest Rates Overrated? Repayment Rates Underrated?

In my writing now, I am sorting through lines of thought on how microlender behavior enhances or reduces the freedom of poor borrowers---freedom in Amartya Sen's definition, as agency in one's own life. The oldest strand here is that of "usury," the idea that charging interest above some level (maybe zero) is unjust, akin to the full-bellied selling food to the starving for a profit. As you probably know, the Compartamos IPO revived within the microfinance world the ancient debate over usury.
