In this paper, we provide solution methods for non-linear rational expectations models in which regime-switching or the shocks themselves may be "endogenous", i.e. follow state-dependent probability distributions. We use the perturbation approach to find determinacy conditions, i.e. conditions...

This paper explores the role of diversification and size in protecting information. We present a simple two period credit market with a sophisticated lender faced with competitors who free ride on his screening activity. Absent commitment problems, the lender funds one borrower and exerts...

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...

By introducing a structure of the balance sheets of the banks, which takes into account their bilateral exposures in terms of stocks or lendings, we get a structural model for default analysis. This model allows distinguishing the exogenous and endogenous default dependence. We prove the...

The spectacular failure of the 150-year old investment bank Lehman Brothers on September 15th, 2008 was a major turning point in the global financial crisis that broke out in the summer 2007. Through the use of stock market data and Credit Default Swap (CDS) spreads, this paper examines the...

Financial institutions’ interconnectedness is a key component of systemic risk. However there is still no consensus on its measurement. Using a unique database of network of exposures of French financial institutions, we compare three strategies to measure interconnectedness: closeness of...

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...

In this paper, we try to illustrate the interest of the Bayesian approach for the evaluation of economic policies, often realised by analysing the response of the economy to a standard shock. We present a Stochastic Dynamic General Equilibrium model for the euro area. The Bayesian estimation...

In this paper, we provide determinacy conditions, i.e. conditions ensuring the existence and uniqueness of a bounded solution, in a purely forward-looking linear Markov switching rational expectations model. We thus settle the debate between Davig and Leeper (2007) and Farmer et al. (2010). The...

Theory and evidence suggest that in an environment of well-anchored expectations, temporary economic news or shocks should not affect agents' expectations of inflation in the long term. Our estimated structural VARs show that both long- and short-term inflation expectations are sensitive to...
