Abstract: Asymmetrical price transmission of agricultural products happens occasionally; one of the important reasons is its perishability. Taking the four products (apples, bananas, potatoes and tomatoes) with different perishable degrees as examples, this paper analyzes the relationship between the degree of perishability and the price transmission in vertical-related markets with the econometric model of timeseries. The results suggest that the asymmetry of price transmission is apparent among perishable products, not among storable products.

Key words: price transmission; vertical market; fruits and vegetables; perishability
