Nudges, Social Norms, and Permanence in Agri-environmental Schemes
研究法国农民在农业环境计划合同结束后是否维持环保行为的决策因素，发现经济和非经济动机均起作用，且社会规范信息（助推）能显著影响其选择，有助于维持计划的长期效果。
The permanence of land management practices adopted under agri-environmental schemes (AESs) is often questioned. This paper investigates the drivers of farmers’ decisions as to whether to maintain “proenvironment” practices beyond the duration of a contract, and in particular the effect of social norms. Our results, based on the stated intentions of 395 French farmers, show that both pecuniary and nonpecuniary motivations drive farmers’ decisions, which are also significantly influenced by information about a social norm. Therefore “nudging” farmers, by conveying information to them on other farmers’ proenvironmental practices, appears to be a means of maintaining the long-run benefits of AESs. <i></i>
