Abstract
Our goal is to examine the effect of different donation solicitation framings on the propensity to donate and donation amounts. In addition, we intend to examine the interaction between solicitation framing and donation matching. Finally, we are interested in examining the association between individual personality traits, solicitation framing and donation amounts.

We intend to test the following research questions:

1) Does donor-oriented solicitation frame lead to more donations than charity-oriented and recipient-oriented frame?
2) Is donation matching less effective for donor-oriented frame?
3) Does solicitation frame which is aligned with donor’s personality traits lead to more donations?
