We analyse a simplified New-Keynesian model with an unobserved aggregate cost-push shock in which firms and the central bank have different information about the shock. We consider a linear policy rule where a pure inflation targeting central bank decides how much to react to the shock given its...

Most studies of optimal monetary policy under learning rely on optimality conditions derived for the case when agents have rational expectations. In this paper, we derive optimal monetary policy in an economy where the Central Bank knows, and makes active use of, the learning algorithm agents...

We show that price level stabilization is not optimal in an economy where agents have incomplete knowledge about the policy implemented and try to learn it. A systematically more accommodative policy than what agents expect generates short term gains without triggering an abrupt loss of...

We investigate the determinants of inertia in Italian inflation, estimating a Phillips curve derived from a general equilibrium business-cycle model that allows for intrinsic and extrinsic sources of inflation persistence, along with trend inflation, and that encompasses both nominal and real...

In most of the recent macroeconomics literature, the sticky reaction of prices in response to changes in aggregate conditions has been modelled following the highly influential contribution of Calvo (1983). However, this approach has difficulties in accounting for some well-established stylized...

We show that a sticky price model featuring firms' heterogeneity in terms of productivity and strategic complementarities in price setting delivers a strictly positive optimal inflation in steady state, differently from standard New Keynesian models. Due to strategic complementarities, more...

This paper documents five stylised facts relating to price adjustment in the euro area, using various micro price datasets collected in a period with relatively low and stable inflation. First, price changes are infrequent in the core sectors. On average, 12% of consumer prices change each...
