Abstract: Network models represent a useful tool to describe the complex set of financial relationships among heterogeneous firms in the system. A dynamic model is proposed for temporal multilayer networks where the different firms' exposures such as return, volatility, and macroeconomic variables are represented as layers. Each adjacency matrix of a layer is modeled as a function of the other layers allowing to characterize the relationships according to the selected exposures. In the empirical analysis, we study the topology of the network before and after the spreading of the COVID-19.
