One remedy to close this gap is to increase the effectiveness of fundraising activities for IHOs. This remedy means spending as little as possible in fundraising activities but, at the same time, still receiving sufficient donations to implement disaster response programs in response to the needs that arise when disasters occur. We contribute to the literature by theoretically developing and estimating a conceptual framework that links donation behavior to the operations that IHOs aim to pursue; the framework incorporates operational costs communicated in appeals, fundraising efforts, and media attention. We argue that effects are not homogenous across disasters but that IHOs can leverage public attention and disaster and appeal characteristics, such as operational costs, to increase donations. We test the framework on a unique data set for disaster response programs operated by the International Federation of Red Cross and Red Crescent Societies (IFRC), covering 174 disasters to which the IFRC responded between 2010 and 2017. 收起
