A random variable dominates another random variable with respectto the covariance order if the covariance of any two monotone increasingfunctions of this variable is smaller. We characterize completely thecovariance order, give strong sufficient conditions for it, present a numberof examples in...

Das multivariate Analyseverfahren der Kausalanalyse gewinnt zunehmend an Bedeutung für die Untersuchung komplexer betriebswirtschaftlicher Zusammenhänge. Neben dem im deutschsprachigen Raum etablierten Verfahren der Kovarianzstrukturanalyse zur Schätzung von Kausalmodellen wird im...

State price density (SPD) contains important information concerning market expectations. In existing literature, a constrained estimator of the SPD is found by nonlinear least squares in a suitable Sobolev space...

We explore connections between the certainty equivalent return (CER) functional and theunderlying utility function. Curvature properties of the functional depend upon how utilityfunction attributes relate to Hyperbolic Absolute Risk Aversion (HARA) type utility functions.If the CER functional is...

This paper provides a longitudinal perspective on changes in Spanish male earnings inequality for the period 1993-2000, by decomposing the earnings covariance structure into its permanent and transitory parts. According to the Spanish sample of the European Community Household Panel,...
