This economic lab in the field experiment tests the effects of recognition on voluntary contributions to a public good at the onset of a behavioral intervention. Using a within-subjects design to look at the behavioral differences between no recognition, group and private recognition, three hundred employees of a large Colombian corporation participated in an online public goods game before the intervention. After the intervention, a new selected sample was part of the same design. Recognition has a sizable effect on contributions. The intervention improves the response to private recognition but, strikingly, it has a distributional effect on the cooperative response to the group recognition.
