Heterogeneous efforts in voluntary programmes on food safety
研究了新鲜农产品进口商在食品安全自愿计划中的努力程度，发现企业规模越大，食品安全努力越低，与环保领域的发现相反。
In this article, we discuss the efforts made by importers of fresh produce within a voluntary programme on food safety. We show theoretically that the larger the firms the lower their efforts directed at food safety. We test this proposition using original primary data from a voluntary programme implemented by French importers of fresh produce. Our results contrast with evidence from environmental economics that large firms are more likely to be proactive with respect to environmental safeguards.
