The empirical literature on the determinants of charitiesâ€™ donation income, distinguishing the charitable cause, is small. We consider the case of development charities specifically. Using a panel covering a quarter of a century, we observe a strong fundraising effect and a unitary household income elasticity. We find evidence that the conventionally identified â€˜priceâ€™ effect may simply be the product of omitted variable bias. Our results further suggest that public spending on development crowds in private donations for development. We find a positive spillover effect of fundraising, suggesting the efforts of one development charity may increase contributions to other development charities.
