In countries with credible inflation targeting, it seems plausible to suggest that instead of forming a rational expectation, some firms (inflation-targeters) might simply expect future inflation to always equal its target. This paper analyses the implications of this for optimal monetary policy...

This paper investigates how best to determine time-invariant policy rules in macroeconomic models with forward-looking constraints, where fully optimal policy is known to be time-inconsistent.  It proposes a new 'coefficient optimisation' approach that improves upon the timeless perspective...

Optimal monetary policy is sensitive to the Phillips curve specification used to represent the dynamics of inflation and output. Most recent literature has used a new Keynesian Phillips Curve based on Calvo pricing. This paper shows that this workhorse model is not robust to relatively minor...

This paper studies the efficient taxation of money and factor income in intertemporal optimizing growth models with infinite horizons, transaction costs technologies and flexible prices.  Second-best optimality calls for a positive inflation tax and a non-zero capital income tax when there are...

Inflation targeting central banks will be hampered without good models to assist them to be forward-looking.  Many current inflation models fail to forecast turning points adequately, because they miss key underlying long-run influences.  The world is on the cusp of a dramatic turning point in...

This paper incorporates limited asset markets participation in dynamic general equilibrium and develops a simple analytical framework for monetary policy analysis. Aggregate dynamics and stability properties of an otherwise standard business cycle model depend nonlinearly on the degree of asset...

A well-known time-inconsistency problem hinders optimal decision-making when policymakers are constrained in their pesent choices by expectations of future outcomes.  The time-inconsistency problem is caused by differences in the preferences of policymakers who exist at different points in...

Time consistency problems can arise when environmental taxes are employed to encourage firms to take irreversible abatement decisions. Setting a high carbon tax, for instance, would induce firms to invest in low-carbon technology, yet once investment has occurred the government can then reduce...

We examine the impact of different degrees of fiscal feedback on debt in an economy with nominal rigidities where monetary policy is optimal. We look at the extent to which different degrees of fiscal feedback enhances or detracts from the ability of the monetary authorities to stabilise output...

Despite the emerging consensus on the validity of purchasing power parity (PPP) between trading countries in the long run, empirical evidence in favour of the PPP theory is scarce in data predominantly exposed to real shocks. This paper tests for PPP between Norway and its trading partners using...
