Testing the structural interpretation of the price puzzle with a cost channel model
Efrem Castelnuovo ()
Abstract: We estimate a new-Keynesian DSGE model with the cost
channel to assess its ability to replicate the price puzzle ie the
inflationary impact of a monetary policy shock typically arising in VAR
analysis. In order to correctly identify the monetary policy shock, we
distinguish between a standard policy rate shifter and a shock to trend
inflation ie the time-varying inflation target set by the Fed. While
offering some statistical support to the cost channel, our estimated model
clearly implies a negative inflation reaction to a tightening of monetary
policy. We offer a discussion of the possible sources of mismatch between
the VAR evidence and our own.
