A post-doctoral researcher at the Center for Global Development wrote about another way in which cell phones are transforming life for people in Africa, even in one of the poorest countries in Africa, Niger. She discusses some work that shows that the introduction of cell phones led to a reduction in grain price differences between markets. This shows that there are large barriers to acquiring more information and that information technologies, such as cell phones, are reducing the prices to obtaining some information.

In the health context, I have started to see more examples of work that is looking at how information technologies are transforming health service delivery. For example, using cell phones to improve adherence to HIV/AIDS treatments, and even a way for health workers to get their pay checks by cell phone. I can’t wait to see more.
