‘Show me the money’ – The effects of refunds and rebates on donations to fundraisers. 3 minsThe Elevator Pitch• Lab Experiment
• Looking at charitable fundraisers
• Studies the impact on donations of offering refunds and rebates to donors in the event that a fundraiser raises less or more than the target amount
• Motivation: to help charities design fundraisers that maxamise funds raised
Key Terms• Voluntary Contribution Mechanism (VCM)
• Provision Point Mechanism (PPM)
• Refund
• Rebate
Motivation of study• The provision of public goods are essential to our modern economy
• A large array of public goods are provided through voluntary contributions
• Voluntary contribution mechanisms suffer from free-riding - leading to under-provision of public goods
• Mechanisms that are proven to reduce free-riding are valuable to society because they increase the provision of public goods towards an optimal level
Literature Review 3 minsBagnoli & Lipman 1989• Game Theory model of giving
• Suggested fundraiser which best mitigates free-riding: a provision point mechanism (PPM) with refund and rebate
List & Lucking-Reiley (2002)• Tested Bagnoli & Lipman’s model in the field
• Found PPM with Refund significantly increased donations vs. open request for donations
Marks & Croson (1998)• Tested Bagnoli & Lipman’s model in the lab
• Looked at the impact on giving of different rebate rules on a PPM with Refund
• Utilisation Rebate
• Proportional (cash) Rebate
• No Rebate
• Found results consistent with Bagnoli & Lipman
• Donations under Utilisation Rebate significantly higher than No rebate
• No difference between Proportional Rebate and No Rebate
My Study 3 minsAims• Look at the impact of rebates in the field
• Purpose is to determine whether Marks & Croson’s findings can be generalised outside of the lab
• By doing so improve the field picture regarding Bagnoli & Lipman’s predictions about voluntary contributions
Hypotheses• A PPM + Refund fundraiser which has a utilisation rebate will raise more funds than a fundraiser with a proportional (cash) rebate
• A PPM + Refund fundraiser (regardless of rebate) will raise more funds than a fundraiser with no refund
Design• Partner with a charity (Life Goes On)
• Allow them to conduct three separate fundraisers
o Fundraiser 1: No rebate or refund
o Fundraiser 2: Refund + Proportional Rebate
o Fundraiser 3: Refund + Utilisation Rebate
• Receive De-personalised data from charity
• Number of prospective donors that donated, and the amount they donated
Progress, Plans and Questions 1 minMy Progress to Date• Literature Review
• Study Design
• Secured in-principle support of Life Goes On
• In discussion with The Salvation Army and Oak Tree to also involve them in the study
My Proposed Next Steps• Ethics Approval
• Confirm involvement of The Salvation Army and The Oak Tree Foundation
• Allow charities to conduct their fundraisers
• Collect de-personalised data & conduct analysis
Questions I Have• What are your thoughts regarding the ethics approval process - and knowledge of past studies
• What are your thoughts on the statistical tests we should use?
