Abstract. We use a recently proved fluctuation theorem for currents to
develop a response theory of non-equilibrium phenomena. In this framework,
expressions for the response coefficients of the currents at arbitrary orders in
the thermodynamic forces or affinities are obtained in terms of the fluctuations
of the cumulative currents and remarkable relations are obtained which are the
consequences of microreversibility beyond Onsager reciprocity relations.
