Several legal missions from the Federal Planning Bureau require the construction of long-term macroeconomic scenarios for the Belgian economy. In order to increase the consistency of these scenarios and to build them within a rigorous theoretical framework, it appeared important to develop a new...

The concepts of potential growth and output gap are important tools to evaluate the state of the business cycle and to assess the supply-side capacity of an economy. They have also become an essential ingredient of the European fiscal surveillance process. However, the global economy is facing...

This paper presents the main improvements carried out to the macroeconometric model MZE since its creation in 2003. We have back-calculated the series over the period 1980-1995, in order to make the model more stable. To our knowledge, this paper is the first application of Kllians (1998) method...

Within the framework of its activity-based payment system, introduced in 2005, the French government is now seeking to achieve price convergence between public and private hospitals.
