      abstract = {This paper analyzes the farm, wholesale, and retail price  series of nine agricultural prcxiucts (rice,
beans, maize,  soyabeans, potatoes, onions, bananas, tomatoes, and  oranges). Causality analysis is carried out to
determine  the possible existence of a market level that  systematically tends to lead price changes. Immediate  and
total elasticities of price transmission are estimated  to provide evidence regarding the relative siz.e of price  variations
at different market levels. All results relate  to the city of Sao Paulo, as a consumption centre, and the  relevant
supplying wholesale firms and production regions.  For most of the products analyzed (those traded  predominantly
in the domestic market), wholesale was  detected to be the market level at which price changes were  initiated. For
products traded internationally-like  soyabeans and oranges-the fann level was apparently the  point from which price
changes are transmiued to the  domestic market. Price transmission may also originate at  the retail level for
products with high income elasticity  of demand or with a conswnption pattern affected by weather  conditions, like
oranges and tomatoes. In general, a price  change initiated at the wholesale level is reasonably  reduced when it
reaches the retail level. Ahnost all other  price changes tend to be transmitted approximately  proportionally between
market levels. Price transmission is  distributed over time, but most of the variation tends to  be transmitted within
three months of the initial shock.},
