We deal separately with the cases where spot market competition is in quantities and … types of competition the introduction of a forward market significantly lowers prices. The combination of supply function … competition with a forward market leads to high efficiency levels. …

A New Compact Linear Programming Formulation for Choice Network Revenue Management
Kunnumkal, Summit; Talluri, Kalyan - Barcelona Graduate School of Economics (Barcelona GSE) - 2012
The choice network revenue management model incorporates customer purchase behavior as a function of the offered products, and is the appropriate model for airline and hotel network revenue management, dynamic sales of bundles, and dynamic assortment optimization. The optimization problem is a...

An Enhanced Concave Program Relaxation for Choice Network Revenue Management
Meissner, Joern; Strauss, Arne; Talluri, Kalyan - Barcelona Graduate School of Economics (Barcelona GSE) - 2011
The network choice revenue management problem models customers as choosing from an offer-set, and the firm decides the best subset to offer at any given moment to maximize expected revenue. The resulting dynamic program for the firm is intractable and approximated by a deterministic linear...

On the Tractability of the Piecewiselinear Approximation for General Discrete-Choice Network Revenue Management
Kunnumkal, Sumit; Talluri, Kalyan - Barcelona Graduate School of Economics (Barcelona GSE) - 2014
The choice network revenue management (RM) model incorporates customer purchase behavior as customers purchasing products with certain probabilities that are a function of the offered assortment of products, and is the appropriate model for airline and hotel network revenue management, dynamic...

A Tractable Consideration Set Structure for Network Revenue Management
Strauss, Arne; Talluri, Kalyan - Barcelona Graduate School of Economics (Barcelona GSE) - 2012
The dynamic program for choice network RM is intractable and approximated by a deterministic linear program called the CDLP. When the segment consideration sets overlap, the CDLP is difficult to solve. A weaker formulation (SDCP+) is tractable and approximates the CDLP value very closely. We...

Equivalence of Piecewise-Linear Approximation and Lagrangian Relaxation for Network Revenue Management
Kunnumkal, Sumit; Talluri, Kalyan - Barcelona Graduate School of Economics (Barcelona GSE) - 2011
The network revenue management (RM) problem arises in airline, hotel, media, and other industries where the sale products use multiple resources. It can be formulated as a stochastic dynamic program but the dynamic program is computationally intractable because of an exponentially large state...

Bundling in Telecommunications
Garcéa-Mariñoso, Begoña; Martinez-Giralt, Xavier; … - Barcelona Graduate School of Economics (Barcelona GSE) - 2008
The paper offers an overview of the literature on bundling in the telecommunications sector and its application in the Spanish market. We argue that the use of bundling in the provision of services is associated to technological reasons. Therefore, there appears no need to regulate bundling...

Who should pay for two-way interconnection?
Hurkens, Sjaak; López, Angel L. - Barcelona Graduate School of Economics (Barcelona GSE) - 2014
European and the US mobile communication services markets have developed in rather different ways. There are striking differences in termination regulation and retail pricing models and one may wonder why this occurred and whether either of the markets outperforms the other in terms of...

Bayesian Nash Equilibrium in "Linear" Cournot Models with Private Information about Costs
Hurkens, Sjaak - Barcelona Graduate School of Economics (Barcelona GSE) - 2012
Calculating explicit closed form solutions of Cournot models where firms have private information about their costs is, in general, very cumbersome. Most authors consider therefore linear demands and constant marginal costs. However, within this framework, the nonnegativity constraint on prices...
