Market liquidity is the ease of trading an asset. Its risk is the potential loss, because a security can only be traded at high or prohibitive costs. While the omnipresence and importance of market liquidity is widely acknowledged, it has long remained a more or less elusive concept. Treatment...

This paper argues that book-to-market and size attributes represent sensitivities of firm returns to several risk factors, and in so doing they subsume the information in other attributes.

This paper estimates a trivariate two-factor conditional version of the Intertemporal CAPM of Merton (1973).

This paper tests a conditional version of Adler and Dumas' (1983) International CAPM with regime switching GARCH parameters.

This paper delevops a tools to analyse the ordering of concordance of random vectors.

Market liquidity risk, the difficulty or cost of trading assets in crises, has been recognized as an important factor in risk management. Literature has already proposed several models to include liquidity risk in the standard Value-at-Risk framework. While theoretical comparisons between those...

It has been frequently discussed, that returns are not normally distributed. Liquidity costs, measuring market liquidity, are similarly non-normally distributed displaying fat tails and skewness. Liquidity risk models either ignore this fact or use the historical distribution to empirically...

The paper deals with the evaluation of Collateralized Debt Obligations forinvestment purposes. CDOs are classified in the asset backed environment. Itsspecific risks (market, timing, recovery, agency) are discussed. To understand theportfolio aspect, the concept of the diversity score is...

We investigate the problem of modeling defaults of dependent credits.In the framework of the class of structural default models we studythreshold models where for each credit the underling ability-to-payprocess is a transformation of a Wiener processes. We propose a modelfor dependent defaults...

This paper proposes validation using simulation based indirect estimation. It uses typical characteristic moments of financial market data to assess the similarity of simulation outcomes.
