Monetary policy aims at affecting corporate borrowing by influencing the marginal costs of firms, but its potency can be conditioned by the degree of market competition.

Recent interest in "Risk Management"has highlighted the relevance of Bayesian analysis for robust monetary-policy making. This paper sets out a comprehensive methodology for designing policy rules inspired by such considerations. We design rules that are robust with respect to model uncertainty...
