Evaluating after the barn-door has been left open: Evaluating Heifer’s Give-a-Goat or Give-a-Cow Programs

The gift of a dairy goat represents a lasting, meaningful way for you to help a little boy or girl on the other side of the world (US$120); or how about a flock of ducks (US$20); or go all out and donate a water buffalo ($250). People need "a cow, not a cup"—cows that could produce milk so families would not have to depend on temporary aid.

International animal donation programs of the type mentioned here are one of the most well-known types of charitable requests, and are used by a number of major charities worldwide.

Does gender matter in migration? Why I don’t believe any studies which claim it does

Since I’ve had three emails in one week asking me about this issue, I figured I might as well blog about it and have something to refer people to instead. The questions have all been variants of:

·         Are women better remitters than men?

·         Does having mothers migrate result in worse outcomes for kids than having their fathers migrate?
