This paper studies the behavior of a central bank that seeks to conduct policy optimally while having imperfect credibility and harboring doubts about its model. Taking the Smets-Wouters model as the central bank's approximating model, the paper's main findings are as follows. First, a central...

The fiscal position of many countries is worrying - and getting worse. Should formally independent central bankers be concerned that observed fiscal excesses spill over to monetary policy, and jeopardize price stability? To provide some insights this paper tracks the interactions between fiscal...

Discretionary policymakers cannot manage private-sector expectations and cannot co- ordinate the actions of future policymakers. As a consequence, expectations traps and coordination failures can occur and multiple equilibria can arise. In order to utilize the explanatory power of models with...

We incorporate inferential expectations into the Barro-Gordon model (1983a) of time inconsistency and consider reputational equilibria. The range of sustainable equilibria shrinks as the private sector becomes more belief-conservative.

We introduce financial market friction through search and matching in the loan market into a standard New Keynesian model. We reveal that the second order approximation of social welfare includes the terms related to credit, such as credit market tightness, the volume of credit, and the loan...

One way of evaluating how well monetary authorities perform is to provide the public with a regular and independent second opinion. The European Central Bank (ECB) and the Bank of England (BoE) are shadowed by professional and academic economists who provide a separate policy rate recommendation...

We examine policy rate recommendations of the Bank of Canada’s Governing Council (GC) and its shadow, the C.D. Howe Institute’s Monetary Policy Council (MPC). Individual recommendations of the MPC are observed but not those of the GC. Differences in the two committee’s recommendations are...

Monetary and fiscal policies interact in many ways. Recently, the stance of fiscal policy in a number of countries (including the EU and the US) has raised concerns about risks for the outcomes of monetary policy. Our paper first shows that these concerns are justified since - under an ambitious...

This paper shows an avenue through which a numerical inflation target ensures low inflation and high credibility: one that is independent of the usual Walsh incentive contract. Our novel game theoretic framework - a generalization of alternating move games - formalizes the fact that since the...
