    Monetary policy transmission lags create credibility problems for the inflationtargeting policy maker who acts under discretion. We show that if prices react to monetary policy with a longer lag than output, the welfare maximizing inflationtargeting policy implies no policy stabilization of cost-push shocks in the canonical New Keynesian model. The reason is simple: for the period monetary policy influences output, inflation is predetermined and the best discretionary policy is to stabilize the output gap fully. We find that money growth targeting comes close to replicating the welfare-maximizing policy under commitment if there are transmission lags. Keywords: discretionary and stabilization bias, monetary policy, transmission lags, inflation targeting, money targeting JEL classification numbers: E52, E58, E61

    This study discusses the effects of financial intermediation, banks' moral hazard and monitoring on monetary policy transmission in a simple model where borrowers are dependent on loans granted by banks with superior monitoring skills.As distinct from the prior literature on monetary policy transmission, this study does not regard banks' deposit funding as a reason for their special role in the monetary transmission.Instead, we focus on banks' role in monitoring their loan customers as part of financial intermediation and on the effects of monitoring on monetary policy. We find that when the intensity of monitoring is endogenous banks acting as financial intermediaries with moral hazard problems respond less to monetary policy in lending than nonintermediary lenders that only lend their own capital without moral hazard problems.We also find that in the model the lending response of intermediary banks to monetary policy depends on the ratio of their own capital to the volume of lending.The finding is fairly insensitive to the market structure of the banking sector.In the case of a monopoly bank, an increase in the bank's capital-to-loans ratio always weakens the transmission of monetary policy to bank lending.In the case of competitive banks, an increase in the capital-to-loans ratio weakens the transmission of monetary policy to aggregate bank lending, up to a critical level. Using a data set covering the Finnish banking sector in 1995-2000, we also offer some tentative empirical evidence that is broadly consistent with the model.Banks with higher capital ratios tend to respond less to changes in monetary policy.Our conclusion is that the outcome of the model might be helpful in explaining the heterogeneity of banks' responses to monetary policy, which frequently observed in the empirical literature.
