Good collection of essays

From 52 prominent economists:

This is a compendium of fifty-four papers written by distinguished economists in response to an invitation by the National Science Foundation's Directorate for the Social, Behavioral and Economic Sciences (NSF/SBE) to economists and relevant research communities in August 2010 to write white papers that describe grand challenge questions in their sciences that transcend near-term funding cycles and are "likely to drive next generation research in the social, behavioral, and economic sciences." These papers offer a number of exciting and at times provocative ideas about future research agendas in economics. The papers could also generate compelling ideas for infrastructure projects, new methodologies and important research topics.

Contributors include James Heckman, Daron Acemoglu,
David Cutler, Esther Duflo, and Hal Varian.
