中文摘要
尼日利亚游牧牧民与定居农业社区之间的暴力冲突,源于两个群体围绕土地和自然资源使用的争夺,部分原因在于气候变化。我们构建理论与证据,研究农业家庭内部个体对牧民相关暴力的劳动响应,并考察一种“暴力阴影”机制,即此前的暴力事件暴露会改变个体对近期事件的劳动响应。利用2010年至2019年的面板数据,我们揭示了暴露于暴力如何在种植季或收获季、以及在男性或女性之间导致不同的响应。在种植季,对于此前未经历过牧民相关暴力的家庭中的男性和女性,我们发现暴露(即单次暴露)导致家庭企业工作减少;但在此前有过暴露经历的家庭中,暴露(即重复暴露)导致家庭企业工作增加。与此同时,重复暴露于牧民相关暴力仅减少男性的农业工作。这导致总工作时长在单次暴露后下降,而在重复暴露后增加,尤其在女性中如此。在收获季,我们发现单次暴露增加了男性和女性的农业工作,但重复暴露仅减少男性的农业工作。• 我们分析了尼日利亚对牧民相关暴力冲突的劳动响应。• 我们提出了通过重复暴露于牧民相关暴力起作用的“暴力阴影”机制。• 我们记录了不同农业季节和性别下的差异化响应。• 牧民相关暴力可能带来超出暴力直接成本的重大的间接成本。
Abstract
Violent conflict between nomadic herders and settled agricultural communities in Nigeria occurs as both groups clash over the use of land and natural resources, in part, due to a changing climate. We generate theory and evidence to study the labor responses of individuals within agricultural households to herder-related violence and consider a “shadow of violence” mechanism, whereby previous exposure to a violent event alters labor responses to a recent event. Using panel data from 2010 through 2019, we highlight how exposure to violence can lead to differing responses in the planting or harvest seasons and among men or women. In the planting season, among both men and women living in households with no previous exposure to herder-related violence, we find that exposure (i.e., singular exposure) leads to a reduction in household enterprise work, but among households with previous exposure experience, exposure (i.e., repeated exposure) leads to an increase in household enterprise work. Meanwhile, repeated exposure to herder-related violence reduces agricultural work among men only. This leads total hours worked to decline in response to singular exposure and to increase in response to repeated exposure especially among women. In the harvest season, we find that singular exposure increases agricultural work among both men and women, but repeated exposure reduces agricultural work among men only. • We analyze labor responses to herder-related violent conflict in Nigeria. • We propose a ‘shadow of violence’ mechanism via repeated exposure to herder-related violence. • We document differing responses by agricultural season and gender. • Herder-related violence can have meaningful indirect costs beyond the direct costs of violence.
