Monetary And Fiscal Policy

This paper studies the determinacy properties of monetary and fiscal policy rules in a small-scale New Keynesian model. We modify the standard model in two ways. First, we allow positive public debt in the steady state as in Leeper [Journal of Monetary Economics 27, 129–147 (1991)]. Second, we add rule-of-thumb consumers as in Bilbiie [Journal of Economic Theory 140, 162–196 (2008)]. Leeper studied a model in which Ricardian equivalence holds, and he showed that monetary and fiscal policy can be studied independently. In Bilbiie's analysis, rule-of-thumb consumers break the Ricardian equivalence and generate important consequences for the design of monetary policy. In his model, steady-state public debt was equal to zero. We study a model with both rule-of-thumb consumers and positive steady-state public debt. We find that the mix of fiscal and monetary policies that guarantees equilibrium determinacy is sensitive to the exact values of the parameters of the model.

Inflation Targets

What are the effects of a higher central bank inflation target on the burden of real public debt? Several recent proposals have suggested that even a moderate increase in the inflation target can have a pronounced effect on real public debt. We consider this question in a New Keynesian model with a maturity structure of public debt and an imperfectly observed inflation target. We find that moderate changes in the inflation target only have significant effects on real public debt if they are essentially permanent. Moreover, the additional benefits of not communicating a change in the inflation target are minor. (JEL E12, E31, E52, H63)

The Interest Rate

In the discrete-time new-Keynesian model with public debt, Ramsey optimal policy eliminates the indeterminacy of simple-rules multiple equilibria between the fiscal theory of the price level versus new-Keynesian versus an unpleasant equilibrium. If public debt volatility is taken into account into the loss function, the interest rate responds to public debt besides inflation and output gap. Else, the Taylor rule is identical to Ramsey optimal policy when there is zero public debt. The optimal fiscal-rule parameter implies the local stability of public-debt dynamics (“passive” fiscal policy).

Fiscal And Monetary Policy

This thesis is about monetary and fiscal policy in New Keynesian DSGE models. Chapter 2 presents the baseline New Keynesian DSGE model. Monetary policy is in the form of a simple interest rate Taylor-type policy rule, while fiscal policy is exogenous. Chapter 3 extends the model of Chapter 2 to include fiscal policy. Now, both monetary and fiscal policy are allowed to follow feedback rules. Chapter 4 sets up a New Keynesian model of a semi-small open economy with sovereign risk premia. Finally, Chapter 5 builds a New Keynesian DSGE model consisting of two heterogeneous countries participating in a monetary union.Throughout most of the thesis, policy is conducted via "simple", "implementable" and "optimized" feedback policy rules. Using such rules, the aim of policy is twofold: firslty, it aims to stabilize the economy when the latter is hit by shocks; secondly, it aims to improve the economy's resource allocation.
