Whilst philanthropy has long helped fund private initiatives for public good, governments are becoming more interested in expanding this income source as pressures on public spending increase. One outcome of multiple efforts to enhance philanthropy is the growth of giving circles, which involve individual donors collaborating to support causes of mutual interest. This research examines the degree to which giving circles are a good mechanism for enhancing philanthropy. Our overarching interest is to understand if giving circles in the UK and Ireland might serve to grow philanthropy as well as shift the logic of charity to meet the expectations of policy-makers.
