Resumo
The onion is a vegetable consumed by a large part of the world population. Brazil occupies an
important position on the world stage, ranking ninth among the largest producers. Most of the
national production is concentrated in the Southern Region, which accounts for 45% of the
onion production in the country. The state of Goiás currently ranks sixth among the largest
domestic producers, accounting for 14% of Brazilian production. The literature on the
marketing of horticultural products indicates the existence of a concentration process, which is
exercised by the wholesale market, but it is also worth mentioning the fact that the retail
market influences the productive chain due to the market power of the large supermarket
chains. Thus, the objective of this work is to analyze the existence of Asymmetry in Price
Transmission (ATP) among the agents of the onion production chain in Goiás. For the
conduction of the study it was necessary to use econometric models such as the one
developed by Houck 1977). In general terms, the results indicate that 30% of the income
from the sale of the onion, are directed to the rural producer, and the rest is divided between
the wholesale market and the retailer. In addition, the results show that asymmetry occurs in
the speed of transmission of prices among the agents of the onion production chain, with
relative advantage to retail over the other productive links.
