We propose an algorithm to model contagion in the interbank market via what we term the credit quality channel. In … existing models on contagion via interbank credit, external shocks to banks often spread to other banks only in case of a … questions. For that purpose, we propose to measure the potential cost of contagion of a given shock scenario by the aggregated …

Building on ideas from combinatorial optimization tailored to … controlling contagion in case of complete information about an interbank network, we augment the model with three plausible types … contagion losses and the policy authority's ability to control them depend on the assumed fire sale mechanism and the fiscal …
