The main issues that this diploma deals with, are the existence or cooperation of actors and the creation of networks and specifically the financial networks. A network is a data communication system that connects two or more autonomous and independent entities. Two factors are considered interconnected when they can exchange information with each other.
One of the most common aspects of the modern financial environment is the rich network of interconnections between businesses. Although financial liabilities due from one business to another are usually formulated as one-way liabilities that depend only of the issuer's financial position, in fact, the liability structure of the corporate liabilities is always much more complex. The value of most businesses depends on the remuneration they receive from their claims on other companies. The value of these receivables in turn depends on the financial position of other companies in the system, so all this creates a financial network. About financial networks will be analyzed their characteristics, the way they are communicated to each other and finally the risk that may arise.
The first chapter is followed by an introduction as well as a bibliographic review and properties of the networks as described by the authors. In Chapter 2 we discuss the general importance of networks, model description, Nash networks, and network options either through one-way flow of information or a two-way flow. In Chapter 3 we delve deeper into the analysis by specifically examining financial networks, their definition in algebra, and the creation of payment vectors. In chapter 4 we discuss about the importance of networks and the incentives that financial institutions have to choose risk in their portfolios. Finally, in Chapter 5 the networks are implemented through the programming language Python to compare the results.
