Abstract: | This article studies a two-period game between the public and a central bank about whose ability to commit to an announced target the public is uncertain. The central bank chooses between announcing a target for an intermediate variable (money growth) and its goal variable, inflation. Prior to setting its instrument, the central bank receives private, noisy information about the link between money growth and inflation. Monetary targeting facilitates communication of the central bank's type, in that the probability of separation is always higher than under inflation targeting. This advantage of monetary targets from a dependable central bank's perspective is outweighed for most parameter values by the advantage of inflation targeting in terms of inflation control. If the regime choice is treated as a strategic decision, over a large range of parameter values both central banks choose the regime that a dependable central bank would prefer. |
