Abstract
This study investigates asymmetric price transmission (APT) in the Finnish food retail sector using a nonlinear autoregressive distributed lag (NARDL) model. Monthly wholesale and retail price data from 2017 to 2023 are analyzed across eight food categories defined by the COICOP classification. The results indicate significant differences in price transmission elasticities and adjustment speeds across product categories. For instance, long-run asymmetries
are substantial in Cereals and Bread and Fruits and Berries, while short-run asymmetries are pronounced in Fish and Milk, Cheese, and Eggs. Adjustment speeds vary from Meat adjusting within four months to Fish taking up to thirteen months.
