We study how aggregate volatility is influenced by the propagation of idiosyncratic shocks across firms through the network of ownership relations. We use detailed data on cross-holdings as well as the relevant balance sheet information for almost the entire universe of Italian limited liability...

In this paper we conduct a simulation run on a sample of Italian banks where a trigger shock, a one-off event fairly large in size, spreads through the interbank network in a set-up featuring among the actors both commercial banks and the authorities. The banks deleverage to comply with a...

This paper provides theoretical background to the increasing R&D cooperation among firms and public research institutions. We find that R&D spillovers may impede cooperation among firms or research institutions even when the cost of forming a link is negligible. Further, the presence of...

The paper investigates how the characteristics of the distribution network and the affiliation to a banking group affect mutual funds performance exploiting a unique dataset with extremely detailed information on funds' portfolios and bank-issuer relationships for the period 2006-2017. We find...

The paper develops a theoretical framework to analyze the connection between the structure of banking networks and their resilience to systemic shocks. We base our analysis on the model of interbank contagion proposed by Cifuentes, Ferrucci and Shin (2005), which accounts for the impact of...

This paper presents a model of non-cooperative network formation in which the marginal benefit of new links eventually decreases. Agents link with each other to gain information and update their links according to better-reply dynamics. In the long run the system settles to a unique network...

The aim of the paper is to estimate a reliable quarterly time-series of potential output for the Italian economy, exploiting four alternative approaches: a Bayesian unobserved component method, a univariate time-varying autoregressive model, a production function approach and a structural VAR....

Optimal Portfolio Theory prescribes that investors reduce their exposure to financial market risk as they get near to retirement. To assess the effect of ageing on portfolio choices, we study the case of an Italian defined contribution pension fund during the period 2002-08. We find that on...
