Bank and Sovereign Debt Risk Connection
(2013-01-01)
Euro area data show a positive connection between sovereign and bank risk, which increases with banks’ and sovereign long run fragility. We build a macro model with banks subject to moral hazard and liquidity risk (sudden ...
Monetary Policy and Risk Taking
(2016-05-19)
We assess the effects of monetary policy on bank risk to verify the existence of a risk-taking channel — monetary expansions inducing banks to assume more risk. We first present VAR evidence confirming that this channel ...
Endogenous Banks’ Networks, Cascades and Systemic Risk
(2014-06-01)
We develop a network model whose links are governed by banks' optmizing decisions and by an endogenous tâtonnement market adjustment. Banks in our model can default and engage in re-sales: risk is transmitted through direct ...
Monetary Policy Implementation in an Interbank Network: Effects on Systemic Risk
(2014-03-26)
This paper makes a conceptual contribution to the effect of monetary policy on financial stability. We develop a microfounded network model with endogenous network formation to analyze the impact of central banks' monetary ...
Systemic Risk in an Interconnected Banking System with Endogenous Asset Markets
(2014-03-30)
We analyze the emergence of systemic risk in a network model of interconnected bank balance sheets. The model incorporates multiple sources of systemic risk, including size of financial institutions, direct exposure from ...
Exit Strategies
(2014-04-01)
We study alternative scenarios for exiting the post-crisis fiscal and monetary accommodation using a macromodel where banks choose their capital structure and are subject to runs. Under a Taylor rule, the post-crisis ...
Austerity
(2014-11-19)
We shed light on the function, properties and optimal size of austerity using the standard sovereign model augmented to include incomplete information about credit risk. Austerity is defined as the shortfall of consumption ...
Cross-Border Resolution of Global Banks
(2015-03-01)
Most recent regulations establish that resolution of global banking groups shall be done according to bail-in procedures and following a Single Point of Entry (SPE) as opposed to a Multiple Point of Entry (MPE) approach. ...
Bank Networks: Contagion, Systemic Risk and Prudential Policy
(2015-07-01)
We present a network model of the interbank market in which optimizing risk averse banks lend to each other and invest in non-liquid assets. Market clearing takes place through a tâtonnement process which yields the ...
Multiplex interbank networks and systemic importance: An application to European data
(2015-05-01)
Research on interbank networks and systemic importance is starting to recognise that the web of exposures linking banks balance sheets is more complex than the single-layer-of-exposure approach. We use data on exposures ...
