Quality Variations a N D Maximal Variety Differentiation*
نویسنده
چکیده
We allow quality variations in a duopoly of locationally differentiated products a-la-Hotelling (1929). We analyze the impact of quality variations on the choices of the varieties produced. We show that in a sequential game of variety choice and subsequent quality and price choice there exist only maximal variety differentiation equilibria in pure strategies. Maximal variety differentiation is also the perfect pure strategies equilibrium of a sequential game of variety choice followed by quality choice and later by price choice. In both games there is minimal quality differentiation at equilibrium.

We study an interesting class of Banach function algebras of innitely dierentiable functions onperfect, compact plane sets. These algebras were introduced by Honary and Mahyar in 1999, calledLipschitz algebras of innitely dierentiable functions and denoted by Lip(X;M; ), where X is aperfect, compact plane set, M = fMng1n=0 is a sequence of positive numbers such that M0 = 1 and(m+n)!Mm+n ( m!Mm)...

متن کاملMAXIMAL PRYM VARIETY AND MAXIMAL MORPHISM
We investigated maximal Prym varieties on finite fields by attaining their upper bounds on the number of rational points. This concept gave us a motivation for defining a generalized definition of maximal curves i.e. maximal morphisms. By MAGMA, we give some non-trivial examples of maximal morphisms that results in non-trivial examples of maximal Prym varieties.

In this article, Finite Element Method (FEM) and Eulerian-Lagrangies Algorithm (ELA) formulation were used to numerically simulate the impact of several low-velocity projectiles with water surface. Material models which were used to express behavior of air and water included Null material model. For the projectiles, rigid material model were applied. Results were validated by analyzing the impa...
متن کاملMathematical Model for Bi-objective Maximal Hub Covering Problem with Periodic Variations of Parameters
The problem of maximal hub covering as a challenging problem in operation research. Transportation programming seeks to find an optimal location of a set of hubs to reach maximum flow in a network. Since the main structure's parameters of the problem such as origin-destination flows, costs and travel time, change periodically in the real world applications, new issues arise in handling it. In t...
