Simple models of monetary policy often imply optimal policy behavior that is considerably more aggressive than what is commonly observed. This paper argues that such counterfactual implications are due to model restrictions and a failure to account for multiplicative parameter uncertainty,...

Using stochastic simulations of the Reserve Bank of New Zealand s macroeconomic model, this paper examines the implications for monetary policy of uncertainty about the length of the monetary policy transmission lag. Uncertainty is examined from two perspectives. The first investigates the...

When generating conditional forecasts in dynamic models it is common to impose the conditions as restrictions on future structural shocks. However, these conditional forecasts often ignore that there may be uncertainty about the future development of the restricted variables. Our paper therefore...

How does inflation affect the investment decisions of financially constrained firms in the presence of corporate taxation? Inflation interacts with corporate taxation via the deductibility of i) capital expenditures and ii) interest payments on debt. Through the first channel, inflation...

This paper examines the effects of expenditure-based fiscal consolidation when credibility as to whether the cuts will be long-lasting is imperfect. We contrast the impact limited credibility has when the consolidating country has the means to tailor monetary policy to its own needs, with the...

In this paper we discuss a number of challenges for structural macroeconomic models in the light of the Great Recession and its aftermath. It shows that a benchmark DSGE model that shares many features with models currently used by central banks and large international institutions has...
