Benefit and Distance Functions
We explore the relationship between R. W. Shephard's input distance function (``Cost and Production Functions,'' Princeton Univ. Press, Princeton, 1953) and D. G. Luenberger's benefit function (J. Math. Econ. 21 (1992a), 461 481). We point out that the latter can be recognized in a production context as a directional input distance function which can exhaustively characterize technologies in bo...
متن کاملBenefit functions and duality
This paper studies a new representation of individ~l preferences termed the benefit function. The benetit function b(g; x,u) measures the amount that an individual is willing to trade, in terms of a specific reference commodity bundle g, for the opportunity to move from utility level a to a consumption bundle x. The benefit function is therefore a generalization of the willingness-to-pay concep...
متن کاملDistance Functions, Instance Functions, and Preference Relations
A standard way of presenting the semantics of default information is via preference relations on models. Under this view, the default information gives rise to a preference relation which orders models according to how well they satisfy it. Diierent ways of deening the relation in terms of the default information can be used to give diierent granularities to the default status the information h...
متن کاملLevel Sets and Distance Functions
This paper is concerned with the simulation of the Partial Diierential Equation (PDE) driven evolution of a closed surface by means of an implicit representation. In most applications, the natural choice for the implicit representation is the signed distance function to the closed surface. Osher and Sethian propose to evolve the distance function with a Hamilton-Jacobi equation. Unfortunately t...
متن کاملComputing Distance Functions and Geodesics
In this paper we review computational techniques for efficiently computing distance functions and geodesics, thereby addressing optimal trajectory problems. These techniques are based on solving the Eikonal equation. Following [30] we first describe how we can numerically solve this equation in a Cartesian grid in O(N) operations, N being the number of grid points. This optimal run-time cost is...
