Before revision:   Our paper introduces a deliberately simplified model which integrates insolvency and illiquidity in financial networks and that can provide answers to the question of how illiquidity or default of one bank can influence the overall level of liquidity stress and default in the network.
After revision:  The main goal of the double cascade model we introduce is to integrate these two facets. In a default cascade, insolvency of a given bank will create a shock to the asset side of the balance sheet of each of its creditor banks. Under some circumstances, such "downstream" shocks can cause further insolvencies that may build up to create a global insolvency cascade. On the other hand, in a stress cascade, illiquidity that hits a given bank will create a shock to the liability side of the balance sheet of each of its debtor banks. Such "upstream" shocks can cause further illiquidity stresses that may build up to create a global illiquidity cascade. Our paper introduces a deliberately simplified model which integrates insolvency and illiquidity in financial networks and that can provide answers to the question of how illiquidity or default of one bank can influence the overall level of liquidity stress and default in the network.
