Distress propagation occurs in connected networks, its rate and extent being dependent on network topology. To study this, we choose economic production networks as a paradigm. An economic network can be examined at many levels: linkages among individual agents (microscopic), among firms/sectors (mesoscopic) or among countries (macroscopic). New emergent dynamical properties appear at every level, so the granularity matters. For viral epidemics, even an individual node may act as an epicenter… Expand

Simultaneous supply and demand constraints in input–output networks: the case of Covid-19 in Germany, Italy, and Spain
Natural and anthropogenic disasters frequently affect both the supply and demand side of an economy. A striking recent example is the Covid-19 pandemic which has created severe disruptions toExpand


Disentangling shock diffusion on complex networks: identification through graph planarity
A novel methodology is proposed which combines vector autoregression model with an unique identification restrictions obtained from the topological structure of the network to uniquely characterize cascades. Expand
The interconnected wealth of nations: Shock propagation on global trade-investment multiplex networks
This model couples a spreading dynamics, describing how economic distress propagates between connected countries, with an internal contagion mechanism, describing the spreading of such economic distress within a given country, to set-up a quantitative framework to stress-test the robustness of individual countries and of the world economy.

Distress Propagation in Complex Networks: The Case of Non-Linear DebtRank
A dynamical model of distress propagation on complex networks, which is an extension of the DebtRank algorithm, is applied to the study of financial contagion in networks of banks connected to each other by direct exposures and finds that the overall stability of the system increases between 2008 and 2013.

Financial fluctuations anchored to economic fundamentals: A mesoscopic network approach
It is shown that the sectors that are relatively large in size, defined with three metrics, constitute the core of the return networks, whereas the periphery is mostly populated by relatively smaller sectors, which ultimately shapes the optimal portfolios for risk management. Expand
The Network Origins of Aggregate Fluctuations
This paper argues that in the presence of intersectoral input-output linkages, microeconomic idiosyncratic shocks may lead to aggregate fluctuations. In particular, it shows that, as the economyExpand
Community Structure of a Large-Scale Production Network in Japan
This chapter analyzes nationwide supplier–buyer relationship data for nearly a million firms and 4 million transactions in Japan. The production network constructed by firms through their transactionExpand
Large-scale structure of a nation-wide production network
Abstract. Production in an economy is a set of firms’ activities as suppliers and customers; a firm buys goods from other firms, puts value added and sells products to others in a giant network ofExpand
Systemic Risk and Stability in Financial Networks
This paper argues that the extent of financial contagion exhibits a form of phase transition: as long as the magnitude of negative shocks affecting financial institutions are sufficiently small, aExpand

Input Specificity and the Propagation of Idiosyncratic Shocks in Production Networks
This article examines whether firm-level idiosyncratic shocks propagate in production networks. We identify idiosyncratic shocks with the occurrence of natural disasters. We find that affectedExpand
