This study examines relationships between the size of the majority and donor conformity by empirically investigating the impacts of multiple earlier donations on the amount that a subsequent donor contributes to JapanGiving, a donation-based crowdfunding platform. The platform's webpage displays...

A charitable donor typically imitates the majority contribution of other donors. This study examines the relationships between majority size and this so-called donor's conformity behavior, by empirically investigating the impacts of multiple earlier donations on the donation of a subsequent...

The constant elasticity of substitution (CES) function is widely used to model distributional preferences in modified dictator games. However, it has been pointed out that its parameter interpretations are inconsistent and problematic in applications. We constructed a model to address this issue...

In previous work, we proposed a method to address mathematical inconvenience by extending the constant elasticity of substitution (CES) utility function in Inukai, Shimodaira, and Shiozawa (2022, ISER DP No.1195). However, the relationships between the extended CES parameters and the external...

In this paper, I analyze a variety of evidence for Japan and, where available, for the United States on bequest practices, on the importance and nature of bequest motives, on bequest division, on the willingness of individuals to help others, etc., in order to shed light on which model of...

This paper discusses three alternative assumptions concerning household preferences (altruism, self-interest, and a desire for dynasty building) and shows that these assumptions have very different implications for bequest motives and bequest division. After reviewing some of the literature on...

We examined whether the knowledge that your private donation has a large number of potential recipients causes you to give more or less. We found that the people with blood type O are more likely to have donated blood than those with other blood types, by using a Japan's nationally...

This paper analyzes the determinants of the wealth decumulation behavior of the retired elderly in Japan using unique information from two household surveys, and by so doing, attempts to assess the relative importance of precautionary saving and bequest motives in explaining the lower than...

We measure differences between altruism toward a family member and toward an unknown foreigner using hypothetical questions in internet surveys across five countries: Germany, the US, Singapore, South Korea, and Japan. Our analysis shows that people in all five countries exhibit greater...

In Japan's hometown tax donation system, people can donate to municipalities where they are not resident and in return receive reciprocal gifts from the local governments of those municipalities. A large part of the donated amount can be deducted from their income and residence taxes. This study...
