This work introduces a new model to investigate the efficiency and evolution of networks of firms exchanging knowledge in R&D partnerships. We first examine the efficiency of a given network structure in terms of the maximization of total profits in the industry. We show that the efficient...

We develop a novel stress-test framework to monitor systemic risk in financial systems. The modular structure of the framework allows to accommodate for a variety of shock scenarios, methods to estimate interbank exposures and mechanisms of distress propagation. The main features are as follows....

We develop a framework to analyse the Credit Default Swaps (CDS) market as a network of risk transfers among counter-parties. From a theoretical perspective, we introduce the notion of flow-of-risk and provide sufficient conditions for a bow-tie network architecture to endogenously emerge as a...

Market-based solutions to climate change are widely advocated by financial actors and policy-makers in order to foster a smooth transition to a low-carbon economy. A first important limiting factor to this approach is widely recognized to be the imperfect information on investors' portfolios'...

Financial institutions form multi-layer networks of contracts among each other and exposures to common assets. As a result, the default probability of one institution depends on the default probability of all the other institutions in the network. Here, we show how small errors on the knowledge...

The practice of lobbying in the interest of economic or social groups plays an important role in the policy making process of most economies. We carry out a multi-level network analysis of the relations among lobbying organizations in the EU transparency register, focusing on the domain of...

The explosion of new and pervasive information technologies we witness in the recent years implies that all citizens of the world are potentially only one click away from each other. This comes, however, both with promises and challenges. On the one hand, one may think that it is today easier...

How, and to what extent, does an interconnected financial system endogenously amplify external shocks? This paper attempts to reconcile some apparently different views emerged after the 2008 crisis regarding the nature and the relevance of contagion in financial networks. We develop a common...

In this paper we analyze whether and how a central bank can pursue the objective to lower its exposure to climate-related financial risks in its asset purchase programs while meeting the criteria that define the eligible universe of assets, including market neutrality. Despite focusing on the...

Climate risk brings about a new type of financial risk that standard approaches to risk management are not adequate to handle. Amidst the growing concern about climate change, financial supervisors and risk managers are concerned with the risk of a disorderly low-carbon transition. We develop a...
