Dynamics of Financial Markets

Abstract: Financial markets, banks, currency exchanges and other institutions can be modeled and analyzed as network structures where nodes are any agents such as companies, shareholders, currencies, or countries. The edges (can be weighted, oriented, etc.) represent any type of relations between agents, for example, ownership, friendship, collaboration, influence, dependence, and correlation. We are going to discuss network and data sciences techniques to study the dynamics of financial markets and other problems in economics.

Financial rating with ordinal classification based on the hierarchical SMAA Choquet integral approach

Abstract: We consider financial rating proposing a robust ordinal regression and a stochastic ordinal regression model taking into account interaction in a hierarchy of criteria corresponding to financial and economic indicators underlying the rating. Formally we apply Robust Ordinal Regression (ROR) and Stochastic Multiattribute Acceptability Analysis (SMAA) to a sorting model based on the Choquet integral taking into account a hierarchy of criteria. The advantages of our approach are shown by means of an application to financial rating of European Countries. Economic and financial data used in the analysis are provided by Standard &Poor’s Global Inc.
