The liquidity of financial system plays a central role in systemic crises. In this paper, we show that the ECB haircut policies provided an important liquidity support to distressed financial institutions during the euro area sovereign debt turmoil. Using novel, micro data on the pool of...

In this paper, we take up the analysis of a principal/agent model with moral hazard, with optimal contracting between a competitive investor and an impatient bank monitoring a pool of long-term loans subject to Markovian contagion. We provide here a comprehensive mathematical formulation of the...

We investigate the consequences of banks' liquidity hoarding behavior for the stability of the financial system 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 studies whether greater competition can mitigate agency problems within banks. We measure the intensity of the agency conflict within a bank by the volume of loans that the bank lends to its insiders (e.g., executives). We first check that these loans are a form of private benefit. By...

We use hikes in the countercyclical capital buffer [CCyB] to measure how tighter bank capital requirements affect their solvency and value, according to market participants. Two features of the CCyB in Europe allow for a unique identification strategy of the effect of such requirements. First,...

When supervisors have imperfect information about the soundness of banks, they may be unaware of insolvency problems that develop in the interval between on-site examinations. Supervising banks more often will alleviate this problem but will increase the costs of supervision. This paper analyzes...

The advent and spread of information and communication technologies (ICTs) increase potential output growth. It is uncertain to what extent and for how long they do so. We use the term "new economy" (NE) to describe the acceleration in potential output growth and the attendant and partly...

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 an otherwise unique-equilibrium model, agents are segmented into a few informational islands according to the signal they receive about others' expectations. Even if agents perfectly observe fundamentals, rational-exuberance equilibria (REX) can arise as they put weight on expectational...

Monetary union can benefit countries suffering from policy credibility problems if it eliminates the inflation bias and also allows for more efficient management of certain shocks. But it also carries costs as some stabilization may be feasible even in the absence of credibility, and this may be...
