Concluding remarks and policy implications
Introduction Mishkin (1982) and Kuttner (2001) empirically show the effects of anticipated monetary policy. More recently, Milani and Treadwell (2012) and Gomes et al. (2013) use a dynamic stochastic general equilibrium (DSGE) model to empirically show that anticipated monetary policy has a large persistent effect. Laséen and Svensson (2011) introduce a numerical computation of the effects of anticipated monetary policy in DSGE models. Moreover, Verona et al. (2013) use numerical simulation with a DSGE model to show that anticipated monetary easing is one of the reasons for the recent boom-bust cycles. However, theoretical studies of this buy Nutlin3a policy are rare. In this short study, we theoretically analyze the effects of anticipated monetary policy by using a simple new Keynesian model consisting of three equations (the IS curve, interest rate rule, and new Keynesian Philips curve). The model is a complete subset of that in Milani and Treadwell (2012) and therefore allows for obtaining a closed-form solution. The theoretical results of this paper are useful for considering the intuition behind complicated models. Although we could use full-blown DSGE models such as those of Smets and Wouters (2003) or Christiano et al. (2005) and carry out numerical analysis, a theoretical analysis using a simple model would still be needed to assess how the parameters underlying the model affect the results. From our theoretical analysis, we find that the effect of anticipated monetary policy on current output critically depends on the parameter for inflationary response to a monetary policy rule. If this parameter were relatively low, an anticipated monetary easing would always have a positive effect on output. However, if the parameter were high, the policy would have a negative impact on output. This finding has not been obtained in the literature using numerical analysis. On the other hand, for the assumed parameter space, an anticipated monetary easing always has an inflationary response. This paper is organized as follows. Section 2 presents our model and obtains a closed form of anticipated policy effects on the economy. Section 3 shows our theoretical analysis and presents our results. Section 4 performs a numerical analysis to obtain quantitative results. Finally, Section 5 concludes the paper.
A closed form of anticipated monetary policy Consider the following simple new Keynesian model consisting of three equations,where y, π, and R denote the deviation from the steady state of output, the inflation rate, and the interest rate, respectively. Eq. (1) is the Euler equation obtained by assuming logarithmic preferences, and Eq. (2) is the new Keynesian Philips curve. Eq. (3) denotes a monetary policy rule, where e for all T≥t+1 represents an anticipated monetary policy shock. This shock can also be identified as a news shock. In this paper, this shock can be defined aswhere v denotes the anticipation at period t for monetary policy i periods later. In this paper, we assume that E[v]=m for all t and for all , where denotes the start period of an anticipated monetary policy. This assumption is for simplicity and is not crucial for our qualitative results. Eqs. (1)–(3) are summarized as follows:The coefficient matrix A can be diagonalized as A=QΛQ−1, where Λ is a diagonal matrix with an eigenvalue (denoted as λ1 and λ2) of A as its diagonal elements and Q is a matrix in which the column vector is an eigenvector. Note that the Taylor principle (ϕ>1) is necessary for 1<λ1<λ2. The standard technique to solve a dynamic linear rational expectation model, like the method of Blanchard and Kahn (1980) or Klein (2000), in general, yields the following closed form of endogenous variables:where . Therefore, from QΛ−1Q−1=A−1, we haveNote thatwhere . Let , n=π,y be the first and second elements of AB. Note that when j=1, denotes the effects of the current monetary policy. In this notation, the effects of an anticipated monetary policy, which starts s periods later and ends at T, on the current economy are captured by .
