This paper introduces two equilibrium concepts which extend the notion of Stackelberg competition to cover a general equilibrium framework. From the benchmarks of Cournot-Walras economies and of strategic market games, the introduction of an active leader modifies the working of market power and the configuration of strategic interactions. In the context of a simple pure exchange economy, asymptotic identification and welfare results are thus obtained, about Stackelberg general equilibria, compared to Cournot general equilibria and to the competitive equilibrium.
