Resumo
The aim of this work is to study São Paulo pork marketing at levels of producer, wholesale and
retail. In order to reach the objective was studied marketing margin, price transmission analysis
and asymmetric price transmission test. The marketing margins study showed that retail is the
market level that holds most of the sector's margins, averaging 56% over the analyzed period,
while the wholesale margin and the producer share are on average 8% and 36% respectively.
Regarding the analysis of price transmission, the SVEC model indicated that 1% producer’s prices
variation, turn to 0,74% wholesale price’s variation, while 1% wholesale’s prices variation
repercussion the retail price in 0,5%. Therefore, prices changes are not completely transmitted to
the next stage. Production’s stage is most susceptible to adjustment along the chain, while retail is
the most influencer to other stages prices. Result of the asymmetric error correction model (ECM)
shows that price transmission farmer to retail is asymmetric. Indicating that increases and
decreases in producer prices are not transmitted in the same path by retailers. Such evidence can be
explained by high marketing margins at retailer stage, participation in large retail chains that have
market power, access to information by being in direct contact with consumers and a high degree organization. Even not producing and not having the product, they are agents whose negotiate
through contracts, which incur in less risk.
