Dear Steve,

It was a pleasure catching up with you just now. Thanks for the advice on the grants, by the way, and 
again I may be coming around to ask more questions in the future.

See attached for two working paper updates. They are updates to WP 2012-02 “The Good of the Few: 
Reciprocity in the Provision of a Public Bad” and WP 2010-21 “Favor Trading in Public Good Provision”. 
I’ve given the former the same filename as the file that’s up there; for the latter, the previous filename 
had “feb2011” in it, so I figured I should change the name to match that.

Thanks!

-Sarah
