Abstract: This article deals with the question of leadership on a market. It melts post-keynesian theory and neo-structural theory. Post-keynesian theory puts forward the so-called theory of price leadership according to which a market is divided into leaders (dominant firms) and followers (dominated firms). This theory faces a problem of definition: what is a leader? The leader is the one who is observed by the others: that is the answer of neo-structural sociology, whose methodological tools (networks analysis) allow for precise identifications of who is "central" on a market. Thanks to empirical data based on a field survey led among three hundred restaurants' owners in the surrounding of Lille, we test the theory of price leadership. We establish links between firms' economic profit and their position in the network structure. We show that taking account of the sole structural position is not always enough to explain economic performance, but that it is necessary to also consider symbolic profit of cooking Chefs as explicative variables for structural position (and economic performance). Moreover, we aim at going beyond the intuitive individual property of the notion of leadership, and we show the existence, on the market under study, of a collective leadership, both economic and symbolic.
