models have also been used in international relations for
the evaluation of the impact of treaties and alliances on
trade, so as for testing the effectiveness of trade agree-
ments and organizations.
For all these reasons, the indicated model can effec-
tively be an interesting technical tool for the implemen-
tation of economic data and the investigation of new
economic peculiarities.
5. Conclusion
The strength of the new derived model consists of its
ability to fit very well experimental data, accommodating
not completely understood behaviours and including pre-
vious models, like the Smith model. The possibility to
wor k a t macrolevel through the use of the gauge factor ( 1 )
allows interesting applications in any sector in which
velocities, distancies, oscillations and diffusion are in-
volved. The started tests with economic data are giving
favorable evidence of an interesting assistance of this
model in the interpretation and comprehension of many
phenomena at economic level.
