The neo-Fisher effect and the central bank information (CBI) effect produce similar outcomes: under both, a monetary tightening triggers an increase in inflation and an expansion in real activity. Separate estimates of these effects run the risk of confounding one with the other. To disentangle these two channels, we introduce into a new-Keynesian model a permanent monetary shock that generates neo-Fisher effects and an aggregate demand shock to which the central bank responds that creates CBI effects. We estimate the model on U.S. data. We find that the neo-Fisherian shock is an important driver of inflation, while the CBI shock explains a significant fraction of movements in the nominal interest rate. The CBI shock explains little of inflation and output, but, through counterfactual exercises, we establish that this reflects the central bank's success in isolating the economy from aggregate demand disturbances. These results are shown to hold under full and imperfect information.
