Panic buying? Food hoarding during the pandemic period with city lockdown

Food hoarding is prevalent during the COVID-19 pandemic.To investigate the mechanism of urban consumers’food hoarding behaviors,we categorize hoarding motives into rational and irrational ones.Using random online survey samples from three cities in China,we employ the multivariate probit model to investigate the rational and irrational motives on food hoarding behavior.Our results confirmed the existence of both rational and irrational food hoarding,and also found factors attributing to the different buying behaviors.The amount of food at hand and the expectation on the infection possibility of COVID-19 are two major factors affecting rational hoarding.Bad mood and herd psychology are factors contributing to panic buying.This study provides an empirical evidence to support intervention policies aiming at mitigating panic buying behavior.

赔付模式对财政补贴型农业保险风险保障的影响研究

我国农业保险进入高质量发展阶段,提高保险保障水平是新阶段发展的重要目标之一。本文通过深入分析中美农业产量保险中的典型赔付模式,提出了通过优化农业产量保险赔付模式来提高农业保险保障效果的设想。研究发现:中美主流农业产量保险采取了两种截然不同的赔付模式,中国采取的是比例式赔付,美国采取的是差额式赔付;两种赔付模式差异很大,当保费补贴高于附加费用时,在相同的保费补贴下,差额式赔付比比例式赔付有更高的保额和更高的均值-方差效用。将我国农业保险赔付模式从比例式转为差额式,可以在不改变补贴资金规模的情况下显著地提升农业保险风险保障效果。研究结论为如何在财政约束下提高农业保险保障水平提供了新的可选路径。
