Market share objectives are prominent in many industries, especially where man-agers pay much attention to league table rankings. This paper explores the strategicrationale for giving managers incentives based on market share in an oligopoly com-peting in strategic substitutes. Moreover, the...

Following [10] we continue the study of the problem of expected utility maximization in incomplete markets. Our goal is to find minimal conditions on a model and a utility function for the validity of several key assertions of the theory to hold true....

This paper finds out that the risk exposure of a trader subject to a VaR limit is always lower than that of an unconstrained trader and that the probability of extreme losses is also lower.

Nonlinear AC Optimal Power Flow (OPF) problems are commonly approximatedby linearized DC OPF problems to obtain real power solutions for restructured wholesalepower markets. We first present a standard DC OPF problem, which has thenumerically desirable form of a strictly convex quadratic...

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...

The “End Racial Profiling Act of 2001” (ERPA) states that “nolaw enforcement agent or law enforcement agency shall engage in racial profiling” andmandates states to “collect detailed data on stops, searches, seizures, and arrests.” Wedevelop a stylized dynamic model of highway...

We propose a simplified approach to mean-variance portfolio problems by changingtheir parametrisation from trading strategies to final positions. This allows us to treat,under a very mild no-arbitrage-type assumption, a whole range of quadratic optimisationproblems by simple mathematical tools...

The paper examines questions of local asymptotic stability of randomdynamical systems. Results concerning stochastic dynamics ingeneral metric spaces, as well as in Banach spaces, are obtained. Theresults pertaining to Banach spaces are based on the linearization ofthe systems under study. The...
