Structural Shocks And The Fiscal Theory Of The Price Level In The Sticky Price Model

This paper examines the effects of various structural shocks in the passive monetary-active fiscal regime in which the fiscal theory of the price level is valid, and compares these effects to those suggested by conventional theory (the active monetary-passive fiscal regime), within a framework of the New Keynesian sticky price model. The results suggest that the effects of structural shocks are substantially different in the passive monetary-active fiscal regime. First, a monetary contraction (an increase in the interest-rate) increases the inflation rate persistently, and increases output with lags. Second, a positive government spending shock leads to a consumption rise in the model that predicts a consumption fall based on conventional theory. Third, in response to aggregate-demand and aggregate-supply shocks, a period of inflation above (or below) the steady-state is followed by a period of inflation below (or above) the steady-state. This inflation reversal is also found in the impulse responses of the estimated VAR models during the 1940's and 1950's, which suggests that the passive monetary-active fiscal regime seems to be actually in place during that period.I thank the editor, an associate editor, and two anonymous referees for constructive suggestions, Christopher Sims for discussion on earlier drafts, Minjung Chae for research assistance, and Clayton Reck for editorial help.
