This document summarizes a presentation on encouraging charitable giving in the workplace. It describes two experiments conducted with different companies that tested behavioral economics approaches to increasing donations. The first experiment found that switching the default enrollment for an annual donation increase program from opt-in to opt-out dramatically increased participation. The second experiment tested adding volunteers, fliers, and sweets at a investment bank and found sweets increased donations the most. The presentation concludes by asking attendees to design their own intervention to increase workplace giving based on behavioral insights.
