Mark Muckerheide talks about what it would take to close the gap that international development aims to work on. Right now, Mark's team estimates that many programs get $2 for every dollar they put in. To truly close the gap, it needs to be $20 per dollar in. So how do we get 10 times better? Focus on putting "money in her pockets" and think about measuring efficiency by the benefits to women who make less than $4 per day. That means we need to think about the bigger system, and fixing the market failures that prevent women from participating fully.
