We study the Ramsey optimal monetary policy within the Golosov and Lucas (2007) state-dependent pricing framework. The model provides micro-foundations for a nonlinear Phillips curve: the sensitivity of inflation to activity increases after large shocks due to an endogenous rise in the frequency...

This paper analyses the effects of the European Central Bank's expanded asset purchase programme (APP) on yields and on the macroeconomy, and sheds some light on its transmission channels. It shows, first, that the January 2015 announcement of the programme has significantly and persistently...

We develop a quantitative monetary DSGE model with financial intermediaries that face endogenously determined balance sheet constraints. We then use the model to evaluate the effects of the central bank using unconventional monetary policy to combat a simulated financial crisis. We interpret...

Financial integration in the markets for banks' assets and liabilities makes balance sheet constraints highly correlated across countries, resulting in a high degree of financial and macroeconomic interdependence. Likewise, under financial integration unconventional policies aimed at stabilizing...

We introduce large-scale asset purchases (LSAPs) as a monetary policy tool within a macroeconomic model.We allow for purchases of both long-term government bonds and securities with some private risks. We argue that LSAPs should be thought of as central bank intermediation that can affect the...

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...

The coronavirus (COVID-19) pandemic caused a deep recession globally, as well as in the euro area, accompanied by a steep decline in inflation rates in 2020. This paper reviews some of the main challenges created by the pandemic for inflation measurement and provides micro price data analysis of...
