In this paper, we investigate with a macroeconometric world model how mone-tary policy rules affect economic activity in the euro area. In the economic literature, there is a general consensus that a credible monetary policy rule is to be preferred to discretionary interventions by central banks because monetary surprises can increase expected inflation and worsen economic performance (Kydland and Prescott (1977)). Several monetary policy rules have been proposed, for example, money targeting (Friedman (1956)), inflation targeting (Bernanke et al. (1999)), nominal income targeting (Hall and Mankiw (1994), Frankel and Chinn (1995)), and an interest rate rule that targets inflation and output relative to a reference value (Taylor (1993)). Although the theoretical merits of these rules have been thoroughly discussed in the literature, the empirical investigation of the implications of these rules has only recently commenced (Bryant et al. (1993)).
In this paper, we investigate how automatic fiscal stabilisers affect economic activity in the euro area. For this purpose we apply several shocks to the NIME-model, and we compare the adjustment path of the main macroeconomic variables under a regime that allows the automatic fiscal stabilisers to operate fully, with the results for a regime that tempers the working of the automatic fiscal stabilisers. We also compare the results for the euro area with results for the United States and Japan.
In the second section of this paper, we briefly describe the NIME model. In the third section, we present simulation results for various shocks under two different fiscal regimes.
