Charity with choice Four years ago Research in Experimental Economics 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 Charity with Choice . 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.
