Imperfect credit markets: implications for monetary policy

Gertjan Vlieghe

No 385, Bank of England working papers from Bank of England

Abstract: I develop a model for monetary policy analysis that features significant feedback from asset prices to macroeconomic quantities. The feedback is caused by credit market imperfections, which dynamically affect how efficiently labour and capital are being used in aggregate. I then analyse what implications this mechanism has for monetary policy. The paper offers three insights. First, the monetary transmission mechanism works not only via nominal rigidities but also via a reallocation of productive resources away from the most productive agents. Second, following an adverse productivity shock there is a dynamic trade-off between the immediate fall in output, which is an efficient response to the productivity fall, and the fall in output thereafter, which is caused by a reallocation of resources away from the most productive agents. The more the initial output fall is dampened with a temporary rise in inflation, the more the adverse future effects of the reallocation of resources are mitigated. Third, in a full welfare-based analysis of optimal monetary policy I show that it is optimal to have some inflation variability, even if the only shocks in the economy are productivity shocks. The optimal variability of inflation is small, but the costs of stabilising inflation too aggressively can be large.
