研究了两种主要的法国新鲜蔬菜：西红柿和菊苣，其运输点与零售价格之间关系的存在及其类型的不对称性。每周数据允许在非常详细的级别（例如区域或超市连锁店）考虑这些关系。此外，该方法提出通过使用最近开发的阈值协整方法对价格传导中的不对称性进行隐式处理。我们的研究结果并没有证明人们普遍认为运输点价格上涨完全、迅速地由中间商传递给消费者，而运输点价格下跌的传导速度较慢且不完全。正如文献中已经强调的那样，这些结果可能与两种被认为新鲜蔬菜的易腐烂性质有关。
The existence and the kind of asymmetry that characterize the relationships between shipping-point and retail prices are investigated for two major French fresh vegetables: tomatoes and chicory. Weekly data allow considering these relationships at very detailed levels such as region or supermarket chain. Moreover, the methodology proposes an implicit treatment of asymmetries in price transmission by using recently developed threshold cointegration methods. Our results do not give evidence to the widespread assertion that shipping-point price increases are completely and rapidly passed by middlemen on to consumers while there is a slower and less complete transmission of shipping-point price declines. As already emphasized in the literature, these results may be linked to the perishable nature of the two considered fresh vegetables.
