We develop a dynamic general equilibrium model for the positive and normative analysis of macroprudential policies. Optimizing financial intermediaries allocate their scarce net worth together with funds raised from saving households across two lending activities, mortgage and corporate lending....

We analyze the risk-taking behavior of heterogenous intermediaries that are protected by limited liability and choose both their amount of leverage and the risk exposure of their portfolio. Due to the opacity of the financial sector, outside providers of funds cannot distinguish “prudent”...

This paper proposes a network formation model of an OTC derivatives market where both prices and quantities are bilaterally negociated. The key feature of the framework is to endogenize the network of exposures, the gross and net notional amounts traded and the collateral delivered through...

The shocks on a stochastic system can be defined by means of either distribution, or variable. We relate these approaches and provide the link between the global and local effects of both types of shocks. These methodologies are used to perform stress-tests on the portfolio of financial...

This paper studies the scope for cross-border contagion in the European banking sector using true bilateral exposure data. Using a model of sequential solvency and liquidity cascades in networks, we analyze geographical patterns of loss propagation from 2008 to 2012. We study the distribution of...

This article analyses the dispersion of risk weights for large corporate portfolios and identifies the sources of dispersion among banks in terms of the Basel risk parameters. The analysis focuses on loans granted by 5 large French banking groups to large corporates operating in France and rated...

We study the real effect on banks’ credit supply after a negative liquidity shock. Controlling for demand effects, we take advantage of the exogenous international interbank market freeze in 2007-2008 to assess the causal relation between French banks’ liquidity risk and their lending. We...

This paper proposes a new micro-founded measure to quantify the aggregate capitalisation of banking sectors taking into account both market discipline and regulatory constraints. It allows studying the connection between micro capital shortfalls from an implicit bank specific capital target and...

We investigate the consequences of banks' liquidity hoarding behaviour for the stability of the financial system by proposing a new model of banking contagion through two channels, bilateral exposures and funding shortage. Inspired by the key role of liquidity hoarding in the 2007-2009 financial...

This paper presents the main features of macroprudential policy with a focus on the French case. We first recall the ultimate objective of this policy, which is to prevent and to mitigate systemic risk, i.e. the risk of “widespread disruptions to the provision of financial services that have...
