Abstract

Long-term price adjustments have primarily been examined using low-frequency data. By contrast, this study uses daily data from 2020 to 2025 to investigate the dynamic effects of exogenous shocks—specifically, movement restrictions due to avian influenza, heatwaves, and holidays—on price transmission across different stages of the distribution channel. A vector autoregression with exogenous variables model was employed for the analysis. The findings indicate weak short-run price transmission from the farm-level and wholesale stages to the retail stage. The observed pattern may reflect price rigidity in the retail market, which remains relatively insulated from price shocks at the farm and wholesale levels. This suggests that policy interventions may need to move beyond aggregate measures and be tailored to address potential inefficiencies within each market segment.
