We develop a new methodology that measures conditional dependency. We achieve this by using copula functions that link marginal distributions, here chosen to obey a GARCH-type model with time-varying skewness and kurtosis. We apply this model to daily returns of stock-market indices. We find...

We evaluate how departure from normality may affect the allocation of assets. A Taylor series expansion of the expected utility allows to focus on certain moments and to compute numerically the optimal portfolio allocation. A decisive advantage of this approach is that it remains operational...

In this paper we propose an approach to Asset Liability Management of various institutions, in particular insurance companies, based on a dual VaR constraint for the asset and the surplus. A key ingredient of this approach is a flexible modelling of the term structure of interest rates leading...

This paper analyses the exposure to climate risk of ABS, an asset class frequently pledged as collateral in the European Central Bank (ECB) refinancing operations. This paper focuses on ABS backed by auto loans or loans granted to Small and Medium Enterprises (SMEs) and explores ways to measure...

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...

It has been argued in the literature that emergency liquidity injections should be conducted preferably in the form of open market operations. As we show in the present paper, this is not necessarily the case when liquidity may be alternatively used for speculative purposes during the crisis. In...

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...

We show that an increase in banks' holdings of domestic Sovereign debt decreases the ability of domestic Sovereigns to successfully enact bailouts. When Sovereigns finance bailouts with newly issued debt and the price of Sovereign debt is sensitive to unanticipated debt issues, then bailouts...

In this paper, I show that the existence of non-bank financial institutions (NBFIs) has implications for the optimal regulation of the traditional banking sector. I develop a New Keynesian DSGE model for the euro area featuring a heterogeneous financial sector allowing for potential credit...

Over the recent months, several initiatives have taken place to develop macro-prudential regulation in order to prevent systemic risk and the built-up of financial imbalances. Crucial to the success of such policy is the ability of the macro-prudential authority to identify in due time such...
