- Abstract
- (en) In sub-Saharan Africa in general, and in Benin in particular, the major consumption centers know a rise in prices of major food products despite efforts made by the government to increase the level of food production. This dissertation examines different factors that may explain the persistence of price increase. Econometric results from Dixit-Stiglitz-Krugman model show that variables related to transfer costs such as distance, roads condition between markets, and different vernacular languages affect significantly exchange of food products between rural markets and Cotonou’s retail market. To reduce transfer costs and to access of credit and market information, most traders in wholesale food markets belong to the trading associations. These trading associations adopt strategies to maintain their commercial margins but which have also affect price transmission between rural and retail markets in Benin. Econometric results from standard and asymmetric co-integration models show that, despite the magnitude of transfer cost, Benin food markets are symmetrical integrated. The results from standard and asymmetric error correction models indicate that the speed of prices adjustment on the rural markets is greater than the speed of prices adjustment on Cotonou’s retail market. The results from Granger’s causality test confirm the leadership of rural markets.
