Giving time or giving money? On the relationship between charitable contributions

This paper studies philanthropic behaviour in terms of money and time contributions for charitable organisations. Using a unique dataset, which is representative of the German population, we examine the pure contributions of individuals who give either money or time as well as joint contributions of individuals who give both money and time. We find that the sequential decisions to give to charity and how much to give can be explained by different socioeconomic characteristics. We report particularly pronounced gender differences among pure contributions, an interesting pattern of human capital variables such as income and education, and possible differences in the type of philanthropic goods.
