We propose a framework for estimating network-driven time-varying systemic risk contributions that is applicable to a …-stage fixed-effects quantile approach, which explicitly links bank interconnectedness to systemic risk contributions.

Finally, our evidence provides an indication that the …

We present a network model of the interbank market in which optimizing risk averse banks lend to each other and invest … sale externalities.

We measure systemic importance by means of network centrality and input-output metrics and the …
