Sticky price models featuring heterogeneous firms and systematic firm-level productivity trends deliver radically different predictions for the optimal inflation rate than their popular homogenous-firm counterparts: (1) the optimal steady-state inflation rate generically differs from zero and...

We present a sticky-price model incorporating heterogeneous Firms and systematic firm-level productivity trends. Aggregating the model in closed form, we show that it delivers radically different predictions for the optimal inflation rate than canonical sticky price models featuring homogenous...

This paper aims to contribute to our understanding of inflation dynamics in the United Kingdom by estimating two dynamic stochastic general equilibrium models and assessing the role of nominal and real rigidities within them. We first obtain an empirical representation of the monetary...

Evidence from vector autoregressions indicates that the impact of interest rate shocks on macroeconomic aggregates can substantially be affected by the so-called cost channel of monetary transmission. In this paper we apply a structural approach to examine the relevance of the cost channel for...

This paper studies monetary policy rules in a small open economy with Inflation Targeting, incomplete pass-through and rigid nominal wages. The paper shows that, when nominal wages are fully flexible and pass-through is low to moderate, the monetary authority should target the consumer price...

Using retail scanner data, we find that the probability of price adjustment increases with a product's revenue, and the average absolute size of price adjustment decreases with the product's revenue. Furthermore, the responsiveness of prices to monetary shocks increases with product revenue....

We use microdata to estimate the strength of price selection - a key metric for the effect of monetary policy on the real economy. We propose a product-level proxy for mispricing and assess whether products with larger mispricing respond with a higher probability to identified monetary and...

We determine optimal discretionary monetary policy in a New-Keynesian model when nominal interest rates are bounded below by zero. Nominal interest rates should be lowered faster in response to adverse shocks than in the case without bound. Such "preemptive easing" is optimal because...
