A difficult proposition faces the new ECB president – monetary union remains incomplete, the bank lacks room to manoeuvre in applying new tools, and it is not yet clear what constitutes the new economic ‘normal’.In this episode of 'The Sound of Economics' Bruegel director Guntram Wolff addresses deputy director Maria Demertzis and research fellow Grégory Claeys, who together with senior fellow Francesco Papadia have written a memo to the incoming ECB president.In their note, the authors state that the ECB needs to begin this eight-year term by reviewing monetary policy framework to account for the increasingly uncertain environment in which it will have to operate. In that vein, the incoming president will have to be prepared to emulate previous actions, providing certainty when it cannot be found elsewhere.In addition, the authors propose methods by which the ECB can bolster the euro-area architecture while continuing to fulfil its role in promoting financial stability.For further reading on this topic, we recommend a recent blog post by Grégory Claeys and Tanja Linta on the evolution of the ECB governing council's monetary-policy decision-making process.
