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...

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...

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...

This study uses a Japanese nationwide sample and experimentally compares rebate and matching, both of which are schemes intended to lower the price of monetary donation. Standard economic theory predicts that the two schemes will have the same effect on individuals' donation behavior when their...

We develop an optimal policy assignment rule that integrates two distinctive approaches commonly used in economics—targeting by observables and targeting through self-selection. Our method can be used with experimental or quasi-experimental data to identify who should be treated, be untreated,...

Promoting vaccination is a crucial strategy to end the COVID-19 pandemic; however, individual autonomy should be respected at the same time. This study aimed to discover behavioral economics nudges that can reinforce people’s intention to receive the COVID-19 vaccine without impeding their...

This study experimentally investigated the effects of providing information on public policy’s future outcomes and emphasizing the information with behavioral economics nudges on budgetary decision-making in Japan’s local governments. Public budget officers consider the policy’s efficiency...
