Editor's Note: The next in the long series of faiV experiments—we're going to start sending it out on Mondays rather than Fridays for a bit. That gives me more time on Friday to assemble and write without it coming out well past the start of Asia/Europe weekends. We'll see how that goes on my side and on the opening/clicking side for a few weeks and then, who knows?
And just in case you need a reminder of a some good news, the cheaper of the new malaria vaccines is starting to be deployed in Ivory Coast today.

Editors’ Note: Hi, Laura and Jonathan here. A few of the pieces this week come from people who spent years up close with how poor households actually handle money, and keep coming back with something more tangled than the story usually told, and more persistent. Tim will be back for the next edition. - Laura Freschi and Jonathan Morduch
