Religion as an investment: Comparing the contributions and volunteer frequency among Christians, Buddhists, and folk religionists

The magnitude of the reward of an afterlife promised in the case of Christians is significantly greater than that in relation to both Buddhism and Taiwanese folk religions. The purpose of this study is to investigate whether these differences in the promised rewards of an afterlife across religions and the extent of the belief in the existence of an afterlife within the same religion are positively correlated with religionists' contributions to their religion and the frequency of their voluntary activities. This positive correlation is verified across different religions and within Christianity in regard to the religionists' contributions.
