In this paper we discuss some statistical pitfalls that may occur in modeling cross-dependences with copulas in financial applications. In particular we focus on issues arising in the estimation and the empirical choice of copulas as well as in the design of time-dependent copulas.

This pap er intro duces a general framework for market mo dels, namedM arket M o del Approach, through the concept of admissible sets of for-ward swap rates spanning a given tenor structure. We relate this conceptto results in graph theory by showing that a set is admissible if and only ifthe...

We analyze the problem of real optimal asset allo cation for a p ensionfund maximising the exp ected CRRA utility of its real disp osable wealth.The financial horizon of the analysis coincides with the random deathtime of a representative subscriber. We consider a very general settingwhere...

We cionsider semiparmetric assymetric kernel density estimators when the unkonwn density has support on [0,∞). We provide a unifying framework which contains assymmetric kernel versions of several semiparametric density estimators considered previously in the literature. This framework allows...

In this paper, we characterize explicitly the first derivative of the Value at Risk and the Expected Shortfall with respect to portfolio allocation when netting between positions exists. As a particular case, we examine a simple Gaussian example in order to illustrate the impact of netting...

We are interested in the macroeconomic implications of the separation of ownership and control. An alternative decentralized interpretation of the stochastic growth model is proposed, one where shareholders hire a self-interested manager who is in charge of the firm’s hiring and investment...

This paper investigates the price and volume behavior around buy, sell and holdrecommendations of Swiss stocks, as published in the major financial newspaper in Switzerland. This represents a random selection of recommendations which have been previously released by banks to their customers....

Recent empirical work shows that a better legal environment leads to lowerexpected rates of return in an international cross-section of countries. Thispaper investigates whether differences in firm-specific corporate governancealso help to explain expected returns in a cross-section of firms...

Die aktuelle Corporate Governance Literatur stützt die verbreitete Hypothe-se, dass sicht „gute“ Corporate Governance durch eine höhere Unterneh-mensbewertung manifestiert. Die Mehrzahl der empirischen Studien unter-sucht jedoch nur ausgewählte Corporate Governance Mechanismen...

Using a comprehensive set of listed Swiss companies, our findings suggestthat the size of the board of directors is an independent control mechanism.However, in contrast to previous studies, we do not find a significant rela-tionship between board size and firm performance. This suggests that...
