Abstract: Equilibrium, co-ordination and cycles Theories of business cycles, as they emerge at the beginning of the fifties, essentially focus on co-ordination issues and more precisely on the effects of out-of-equilibrium investment behaviours. New theories, that has been developed from the beginning of the seventies onwards, are based on the so-called equilibrium method and focus on the properties of the utility function, the production function or the ex ante structure of information. They constitute a real challenge for the "old" theories, but they do not make them obsolete insofar as they miss the crucial point which is to explain the nature of a 'multi-phase (or multi-regime) dynamics'.
