Spatial competition with concave transport costs
We study the location-then-price game played by two firms in a circular market when consumers face non-linear transport costs. We show that for any convex transport cost function there exists a concave one such that the location-then-price games induced by these functions are strategically equivalent. Further, we provide a sufficient condition to guarantee that a similar equivalence result hold...
متن کاملNetwork Optimization with Concave Costs
In this paper the problem of minimum cost communication network design is considered where the costs are piecewise linear concave. Several methods are compared: Simulated Annealing method, a heuristic based on the method proposed by Minoux, and a lagrangian method based on lower bounding procedure.

متن کاملLocal Matching Indicators for Transport Problems with Concave Costs
In this paper, we introduce a class of local indicators that enable to compute efficiently optimal transport plans associated to arbitrary weighted distributions of N demands and M supplies in R in the case where the cost function is concave. Indeed, whereas this problem can be solved linearly when the cost is a convex function of the distance on the line (or more generally when the cost matrix...
متن کاملLocal matching indicators for transport with concave costs
Andrĕı Sobolevskĭı A. A. Kharkevich Institute for Information Transmission Problems, Moscow, Russia Abstract In this note, we introduce a class of indicators that enable to compute efficiently optimal transport plans associated to arbitrary distributions of N demands and N supplies in R in the case where the cost function is concave. The computational cost of these indicators is small and indep...
