This paper analyzes a general equilibrium economy featuring input-output connections, imperfect competition, and external economies of scale owing to entry and exit. The interaction of input-output networks with industry-level market structure affects the amplification of shocks and the pattern of d...

In this paper, we study the severity of cascading failures in supply chain networks defined by a node percolation process corresponding to product suppliers failing independently due to systemic shocks. We first show that the size of the cascades follows a power law in random directed acyclic graphs...

Potential critical risks of cascading failures in power systems can be identified by exposing those critical electrical components on which certain initial disturbances may cause maximum disruption to the systems. The authors investigated the cascading failures in power systems described by the dire...

In our study, we introduce indicators that quantify the influence of each country in complex trade scenarios involving the exchange of raw materials, intermediate goods, and final products across multiple countries. We systematically employ an agent-based model to simulate the propagation of failure...
