In this paper we study the degree of precommitment that is required to eliminate multiplicity of policy equilibria, which arise if the policy maker acts under pure discretion. We apply a framework developed by Schaumburg and Tambalotti (2007) and Debortoli and Nunes (2010) to a standard New...

We demonstrate the existence of multiple discretionary equilibria in a mainstream New Keynesian model with capital accumulation. There can be two monetary policy regimes, both of which satisfy conditions of optimality and time consistency. In a response to a cost-push shock one of the regimes...

We study a Markov-perfect monetary policy in an open New Keynesian economy with incomplete financial markets. We analyze inflation and exchange rate targeting regimes and demonstrate that both cases may result in multiple equilibria. These equilibria feature qualitatively and quantitatively...

The fiscal policy environment central banks operate in can be radically different with respect to debt levels, maturity structures and whether or not fiscal adjustments are spending or tax based. Despite this, most analyses of monetary policy delegation schemes typically ignore the behavior of...

This paper extends the concept of discretionary equilibrium for linear-quadratic models with rational expectations by allowing for linear non-Markovian strategies of the policy-maker and the other agents in the economy. Applying this concept to the standard New Keynesian framework, we show that...

This paper develops the theoretical framework and studies discretionary non-cooperative monetary and fiscal policy stabilisation in a New Keynesian model, where the fiscal policymaker uses distortionary taxes as the policy instrument and operates with long periods between optimal adjustments of...

We study stationary discretionary equilibria in dynamic linear-quadratic rational expectations models. Past papers have assumed that this is uniquely determined; we show that such models can have multiple equilibria in some situations. We demonstrate the existence of multiple discretionary...

Focusing on linear-quadratic models with rational expectations, this paper extends the concept of discretionary equilibrium by allowing for linear non- Markovian strategies of the policy-maker and the other agents in the economy. Applying this concept to the standard New Keynesian framework, we...

This paper investigates the stabilization bias that arises in a model of monetary and fiscal policy stabilization of the economy, when monetary authority puts higher weight on inflation stabilization than society. We demonstrate that inflation conservatism unambiguously leads to social welfare...

We study the degree of precommitment that is required to eliminate multiplicity of policy equilibria, which arise if the policy maker acts under pure discretion. We apply a framework developed by Schaumburg and Tambalotti (2007) and Debertoli and Nunes (2010) to a standard New Keynesian model...
