Informal economy border trap in conversation with Sohrab Dalangizan Sardar Khalidi/Editorial Secretary According to the core of the theoretical framework of the economist Gunnar Myrdal, regional concentration and inequality can be reproduced and intensified through the process of agglomeration in the center. On this basis, a point is created in the center that expands the resources, the distribution of power and the rent and like a vortex it attracts all the possibilities to itself. In this way, resources, capable human resources, opportunities, investments and facilities are taken away from the surrounding areas. When resources and facilities move away from peripheral areas, no formal processes are created in these economies and the opportunities that are created remain hidden from the framework of formal processes. Being close to the market of neighboring countries does not necessarily mean the expansion of the official market. The expansion of the formal economy in the economy requires transparent and sound laws. Rules should be written in a way that is easy to understand and enforceable. They should also be worded in such a way that the businessmen and economic operators willingly and willingly agree to it and the government and government agents cannot abuse it. In this situation the formal economy is created. In any economy, where the laws are too vague, do not fit and interfere with the intervention of agents or representatives and government employees, then the economy is outside the official framework. The investor is not sure about the future because of the instability of the laws at the borders, and for this reason he is not very willing to invest in large volumes. For the borders to prosper and develop, the stability of the laws must prevail. Without stability of rules and adequate monitoring, borders become a platform for informal exchanges that can serve as a flawed hole in the body of the system. Borders are managed and developed stably under strict and transparent rules and can be a safe gateway for trade. Unfortunately, border activity in Iran's economy depends on communication and people's relationships rather than laws. Security views and procedures cause many of those organized smuggling networks or drug traffickers to wear different clothes and want to disrupt the borders to continue their activities.
