TY - RPRT AU - Garcia, Thomas AU - Massoni, Sebastien AU - Villeval, Marie Claire TI - Ambiguity and Excuse-Driven Behavior in Charitable Giving PY - 2019/Dec/ PB - Institute of Labor Economics (IZA) CY - Bonn T2 - IZA Discussion Paper IS - 12869 UR - https://www.iza.org/index.php/publications/dp12869 AB - A donation may have ambiguous costs or ambiguous benefits. Behavior in a laboratory experiment suggests that individuals use this ambiguity strategically as a moral wiggle room to act less generously without feeling guilty. Such excuse-driven behavior is more pronounced when the costs of a donation – rather than its benefits – are ambiguous. However, the importance of excuse-driven behavior is comparable under ambiguity and under risk. Individuals exploit any type of uncertainty as an excuse not to give, regardless of the nature of this uncertainty.
