Niels-Hugo Blunch and my paper, "Literacy, Skills, and Welfare: Effects of Participation in Adult Literacy Programs," is out in this issue of EDCC, vol 60(1): 17-66. You can find the published version on JSTOR, at http://www.jstor.org/stable/10.1086/661219. It is rather long, 50 pages, but worth the read if you are interested in literacy programs.
