Four years ago "e;Research in Experimental Economics"e; published experimental evidence on fundraising and charitable contributions. This volume returns to the intrigue with philanthropy. Employing a mixture of laboratory and field experiments as well as theoretical research we present this new volume, "e;Charity with Choice"e;. New waves of experiments are taking advantage of well calibrated environments established by past efforts to add new features to experiments such as endogeneity and self-selection. Adventurous new research programs are popping up and some of them are captured here in this volume. Among the major themes in which the tools of choice, endogeneity, and self-selection are employed are: What increases or decreases charitable activity? and How do organizational and managerial issues affect the performance of non-profit organizations?
