Figure 11. Likely distribution of the average length of ITN sub-networks, overlooking all pairs of countries with a bilateral trade agreement (solid purple) and without agreement (light violet), as there is a direct route between countries. The figures are calculated from the ITN for 2002. It is a list of free trade agreements between two parties in which each party could be a country (or another customs territory), a trade bloc or an informal group of countries. For dies (pout)ij-pijout, the probability of a unit following a path of length α from sector i to sector j, from (pout) ij. By analogy, (Pin)ji measures the flow of corresponding currency units. In order to measure the probability that an accidental hiker will start on the ITN from one area of one country and eventually end in another country, we define the trade interconnection (IT) between the two countries C1 and C2, since the European Agency for Development in the Field of Special Needs, established in 1996, is an independent and self-managed organisation created by the ministries of education of its 29 member countries. as a platform for cooperation in the field of special education, in order to contribute to improving the quality of education. This organisation is supported by the European Commission and Parliament. In March 2016, the U.S. government and the Peruvian government agreed to remove barriers to U.S. beef exports to Peru, which had been in effect since 2003.
The methodology used in this study can be used for follow-up studies of specific BTAs or certain sectoral effects of such agreements. A specific agreement of interest, for example, reveals whether third countries have been discriminated against as a result of this agreement. More detailed case studies will be made possible for input-exit data, with higher sectoral details. We also stress that our approach can still be adapted and extended to allow for an IT impact assessment of multilateral trade agreements such as the North American Free Trade Agreement or the European Union. In addition, impact assessments can also clarify the link between the measures proposed in this work and other economic factors. It is important that the interaction with GDP growth is of great interest. The study of the behaviour of our actions in the context of new growth models of network theory (z.B. [37-40]) is certainly a promising avenue for further research.
