Volunteering time decisions: a multi-factor experimental study

Non-profit organizations often seek volunteers to help staff a fundraising event. In the present research, an experimental study assessed volunteering time decisions for a fundraising event following manipulations of opportunity cost valence, opportunity cost avoidability and question order involving donating time and donating money. Opportunity costs represent foregone alternatives sacrificed (e.g. working) when engaging in an activity (e.g. volunteering), with valence of the opportunity cost indicating the appeal (positive or negative) of the foregone alternative and avoidability of the opportunity cost suggesting how easy it would be to forgo the alternative. Prospective donors are often asked to consider both volunteering time and contributing money, and these two questions posed to individuals can be varied in terms of order. The results of the experiment revealed that individuals intended to volunteer the most time when an opportunity cost was negative and avoidable. The lowest time donation intentions occurred when an opportunity cost was positive and less avoidable with individuals also being asked about donating money prior to being asked to donate time. The results highlighted the importance to non-profit firms of considering opportunity costs potential volunteers face and suggested care in structuring the order of questions involving time and money posed to those individuals.
