Sharing Norm Pressures and Community Remittances: Evidence from a Natural Disaster in the Pacific Islands
研究移民在社区分享规范压力下向家乡社区汇款的行为，利用太平洋岛屿的飓风冲击识别规范压力的影响，发现网络密集地区压力更强且存在捐赠疲劳效应。
Migrants are often subject to social pressures to remit beyond their own households, to share the benefits of migration with the wider community in their home country; these are ‘community remittances’. We hypothesise that community sharing norm pressures are stronger in locations with more extensive home community networks. We also postulate that the responsiveness of remittances to sharing pressures is subject to diminishing returns, attributable to a donor fatigue effect. Using customised survey data from three Polynesian migrant groups in metropolitan and regional Australia, we estimate double-hurdle regression models of community remittances. To identify the effects of sharing norm pressures we exploit an exogenous (cyclone) shock to home country incomes affecting one sub-group. We find strong evidence in support of the postulated responsiveness of community remittances to location-related differences in sharing norm pressures, and the presence of a donor fatigue effect. The policy implications are discussed.
