Résumé
Selling an activity between firms is mainly, in a structural approach, analysed as an adjustment to new market constraints. The aim of this article is to show that a business unit transfer to a competitor may be analysed as the result of an aggressive behaviour of this competitor. This hypothesis is tested through the transfer of Saupiquet's canned vegetables business unit (brand Cassegrain) to Groupe Bonduelle. In particular, it is shown that Groupe Bonduelle, prior to this acquisition, reduced its prices by investing in excessive production capacities. It is assumed that the behaviour of Groupe Bonduelle itself pushed the Compagnie Saupiquet to sell Cassegrain.
