Endogenous Timing in a Mixed Duopoly: Wighted Welfare and Price Competition

In this paper we analyse the endogenous order of moves in a mixed duopoly for differentiated goods. Firms choose whether to set prices sequentially or simultaneously. The private firm maximises profits while the public firm maximises the weighted sum of the consumer and producer surpluses (wighted welfare). It is shown that the result obtained in equilibrium depends crucially on the weigth given to the consumer surplus in weighted welfare and on the degree to which goods are substitutes or complements. We also anlyse whether the equilibria obtained maximise the sum of the consumer and producer suspluses or not. Finally we study whether the nationality of the private firm influences the results.mixed duopoly, price competition, endogenous timing, weighted welfare

Proyecto E-MATH "Uso de las TIC en asignaturas cuantitativas aplicadas"

El projecte e-Math pretén fomentar i difondre la utilització i integració de les eines tecnològiques actuals (Internet i programari especialitzat) en els curricula de diverses assignatures quantitatives aplicades pertanyents a diferents titulacions universitàries. Els resultats del projecte (material docent, articles, conclusions, etc.) són de difusió general, ja que es pretén que puguin ser d'utilitat per a qualsevol universitat (presencial o virtual) interessada a fer ús dels recursos tecnològics en honor d'obtenir una millora substancial en la qualitat docent de les seves assignatures quantitatives aplicades.El proyecto e-Math pretende fomentar y difundir la utilización e integración de las herramientas tecnológicas actuales (Internet y software especializado) en los curricula de varias asignaturas cuantitativas aplicadas pertenecientes a diferentes titulaciones universitarias.

The results of the project (educational material, articles, conclusions, etc.) are of general diffusion, since it pretends that they can be of utility for any university (face-to-face or virtual) interested in doing use of the technological resources in plough to obtain a substantial improvement in the educational quality of his quantitative subjects applied
