Once again I have the great pleasure to present a new edition, the fourth, of the Conference on Input-Output Analysis.
As time passes, the future of SHAIO is increasingly clear, and one indicator of this tour is the celebration of the Conference. Year after year, research groups have taken over and continued with his organization. Year after year, we received this outpouring of generosity and selflessness, a commendable attitude in this day and age where what prevails is the individualism and the pursuit of self interest.
The celebration of this Conference shows that the Input-Output is alive and well, both among the most experienced researchers as among the very young, which is a source of pride and satisfaction on our part.
The forum of the Conference is a meeting point for researchers in the field, a cause for reflection on the issue and exchange of knowledge and experience.
Let me conclude by thanking the organizing committee and their work availability. Thanks and congratulations on the achievement made: the continuation of the Conference.
