The advent and spread of information and communication technologies (ICTs) increase potential output growth. It is uncertain to what extent and for how long they do so. We use the term "new economy" (NE) to describe the acceleration in potential output growth and the attendant and partly...

Two different approaches to central banking in the aftermath of the crisis are contrasted. In the first one, labelled ‘New Normal', the monetary policy strategy is broadened to encompass such objectives as financial stability or full employment. Furthermore, the inflation target is raised and...

In the age of high-frequency trading in financial markets and faster payment services in account-to-account (A2A) transactions of bank retail customers, it may seem odd that the shortest maturity that is traded in the money market is overnight. This situation reflects policies implemented by...

In spite of a still very low volume at the global level, in comparison with the main reserve currencies, digital currencies attract a lot of attention. The paper reminds that it is above all the exchange mechanism incorporated in digital currencies (the distributed ledger technology) which...

This paper examines the effects of introducing a non Walrasian labour market into the "New Neoclassical Synthesis'' framework. A dynamic stochastic general equilibrium model is formulated, solved, and calibrated in order to evaluate its ability to replicate the main features of the Euro area...

This paper proposes a full description of the Calvo price-setting model based on partial prices indexation and studies the interaction between partial indexation and trend inflation. We show that using a hybrid version of the Phillips curve partly decreases the risks of overestimate due to the...
